Feit PLUG3/WIFI/WP/2 Relay Replacement: Omron G5LE-1, Sanyou SJ, Songle SRD Compatible Options

User question

Where can I find a replacement relay?

Artificial Intelligence Response

Direct answer to the question

• You can buy a pin‑compatible PCB power relay from mainstream electronics distributors (Digi‑Key, Mouser, Newark, Arrow, RS, TME) once you read the markings on the original relay and match coil voltage, contact form, rating, and footprint. If you prefer an exact brand match that’s not stocked in the US, check LCSC, AliExpress, or eBay.
• The Feit triple‑outlet outdoor smart plug uses a single PCB relay to switch all three receptacles; identify its exact part number on the can, then order the same part or a fully compatible equivalent. (devices.esphome.io)

Key points

• Match: coil voltage (likely 5 VDC but confirm on the relay body), contact form (SPST‑NO or SPDT used as NO), current/voltage rating (≥ original), and the through‑hole footprint/size.
• Buy from: Digi‑Key, Mouser, Newark, Arrow, RS/TME for genuine, safety‑listed relays; LCSC/AliExpress/eBay for exact low‑cost Chinese brands if needed.
• Typical equivalents you can search for once specs are known: Omron G5LE‑1 (10 A, 5 VDC coil), or Sanyou SJ/SRD “10A cube” family—verify pinout and dimensions. (newark.com)

Detailed problem analysis

• Architecture: The Feit PLUG3/WIFI/WP/2 family uses a BK7231N‑based CB2S radio module that drives a single electromechanical relay feeding all three outlets. That means one relay replacement restores all outlets. (devices.esphome.io)
• Variants: There are at least two board variants (PLUG3/WIFI/WP/2 and PLUG3/WIFI/WP/2‑N). Both have one relay, but internal layout and GPIOs differ. The relay vendor/part can change between production runs—hence the need to read the markings on your board. (devices.esphome.io)
• What to read on the relay:
  • Coil voltage printing (e.g., “05VDC” or “12VDC”).
  • Contact rating (e.g., “10A 250VAC” or “15A 125VAC”).
  • Contact form (SPST‑NO “1A” or SPDT “1C”).
  • Manufacturer and series code (e.g., Omron G5LE‑1, Hongfa HF32F, Songle/Sanyou SRD/SJ… “‑105DM”, etc.).
• Mechanical families you’re likely to see:
  • “10 A cube” relays around 22.5×16.5×19 mm (Omron G5LE) widely used in plugs.
  • Slim 10 A miniatures around 18.2×10.2×15.5 mm (Sanyou SJ/SJ‑10A family, Hongfa HF32F). Your PCB footprint will usually make the choice obvious. (newark.com)
• Why coil voltage matters: The BK7231N runs at 3.3 V and drives the relay through a transistor; the relay coil itself is commonly 5 V in this class of Tuya/Feit devices, but 12 V appears in some products. Ordering the wrong coil voltage will make the relay run hot (too low V) or never pull in (too high V). Confirm the printed coil voltage before buying. (devices.esphome.io)

Current information and trends

• Device docs: Feit’s product and FCC pages confirm the model family and that the PLUG3/WIFI/WP/2 and PLUG3/WIFI/WP/2/RP are the current variants; however, Feit’s public spec sheet doesn’t list the internal relay part number, so reading the relay can is still required. (appshopfy.feit.com)
• Market reality: These outdoor smart plugs are inexpensive in the US, sometimes under $20 for a two‑pack, which can make full unit replacement economically attractive versus repair if you’re short on time/tools. (walmart.com)

Supporting explanations and details

• Pinout/footprint checks:
  • SPST‑NO (4‑pin) packages usually have 2 coil pins and 2 contact pins.
  • SPDT (5‑pin) packages add a common and both NO/NC; many boards use only NO+COM, leaving NC unconnected. Confirm pad count/spacing on your PCB.
• Example “drop‑in” families for 10 A, 5 VDC coil (verify size/pinout against your board):
  • Omron G5LE‑1A DC5 (SPST‑NO) or G5LE‑1 DC5 (SPDT).
  • Sanyou/Songle SRD/SJ “‑105DM” types (SPST‑NO or SPDT variants).
    These examples are UL/cUL listed in many versions; choose a listed version for mains use. (newark.com)
• Where to shop, practically:
  • Authorized channels: Digi‑Key, Mouser, Newark, Arrow, RS, TME—good stock visibility, datasheets, and certification info. (content.mouser.com)
  • If you need an exact niche Chinese brand/marking: LCSC, AliExpress, eBay can help, but verify coil voltage and dimensions carefully.

Ethical and legal aspects

• Safety certifications: Replacing a relay with a non‑listed or lower‑rated part can compromise UL “wet location” compliance printed on the product. As the repairer, you assume responsibility for continued electrical safety. Keep or exceed the original ratings and prefer UL/cUL‑recognized parts.
• Wet‑location integrity: Opening and resoldering can compromise seals. Reseal gaskets and apply conformal coating or silicone where the manufacturer used it. Follow NEC 125 V device safety practices. Product documentation confirms wet‑location rating; your repair must preserve it. (feit.com)

Practical guidelines

1. Identify the relay: Provide a clear photo of the relay top and the solder side of the PCB. Note the text on the can and count the pads.
2. Confirm coil voltage: Look for “05VDC/12VDC” on the can; if illegible, measure the drive voltage across the coil during energize (carefully, with mains isolated) or trace the low‑voltage supply rail.
3. Match dimensions and pin layout:
   • Cube family (e.g., Omron G5LE) ≈ 22.5×16.5×19 mm. (newark.com)
   • Slim family (e.g., Sanyou SJ‑10A) ≈ 18.2×10.2×15.5 mm. (tme.com)
4. Order from a reputable distributor: Example searches: “G5LE‑1 DC5,” “G5LE‑1A DC5,” or “SJ‑S‑105DM 10A 5VDC” and then check drawings vs. your PCB. (newark.com)
5. Desoldering tips: High‑current pads have thermal mass. Use a 60–80 W iron or hot‑air + preheat, add fresh leaded solder to lower the melting point, and use a solder sucker or braid.
6. Re‑seal: After soldering, clean flux, re‑apply conformal coating around mains pads if the original board was coated, and ensure gaskets are seated before closing.
7. Functional check (no load, then load): Verify the relay clicks and that mains continuity appears only when commanded. Start with a small resistive load (e.g., a lamp) before returning to outdoor duty.

Possible disclaimers or additional notes

• Some Feit lots use different PCBs/relays; the teardown and ESPHome pages confirm single‑relay architecture but do not fix a single relay part number. Always trust what’s printed on your specific unit. (elektroda.com)
• Do not up‑rate contact current without checking creepage/clearance and enclosure fit; a larger relay (e.g., 30 A TE T9A) likely won’t fit the footprint even if ratings look attractive. (newark.com)
• Mains work risk: If you’re not experienced with mains‑rated repairs, replacing the entire smart plug may be safer and, given current retail pricing, sometimes more economical. (walmart.com)

Suggestions for further research

• Provide the exact can markings or a photo; I can cross‑reference to a pin‑compatible part at Digi‑Key/Mouser/Newark.
• If you want a reliability upgrade, we can select a relay with the same footprint but higher endurance/contact material (AgSnO2), and evaluate adding or verifying an RC snubber across the load to reduce contact wear (often present from the factory).
• See the ESPHome devices page for your model and the community teardown for board photos and context while you work. (devices.esphome.io)

Brief summary

• Read the relay’s markings, confirm coil voltage, contact form/rating, and footprint, then order from a reputable distributor. Common, safe choices in this class include Omron G5LE‑1/G5LE‑1A (10 A, 5 VDC coil) or Sanyou/Songle “‑105DM” family, provided the footprint and dimensions match your PCB. Your Feit plug has one relay for all three outlets, so replacing that single part restores function—just preserve wet‑location sealing and safety approvals during the repair. (newark.com)

If you share a photo or the exact text printed on your relay, I’ll point you to an in‑stock, pin‑compatible part number at a US distributor.
