Panasonic MIP2H2 Replacement Options: Compatible ICs, Pinout, and Cross-Reference

User question

is there replacement for MIP2H2

Artificial Intelligence Response

Direct answer to the question

• Short answer: Yes, but a true drop‑in, pin‑for‑pin replacement outside the original part is not available. The most reliable fix is to use an original MIP2H2; “equivalents” from other vendors will require circuit changes. (encompass.com)
• Key points:
  • Original MIP2H2 is still obtainable from parts distributors as of November 6, 2025. (encompass.com)
  • Same‑family Panasonic MIP2x parts share the DIP‑7 footprint but are not guaranteed pin‑/parameter‑compatible—verify datasheets before substituting. (datasheetbank.com)
  • Functional alternatives exist (ST VIPer, Power Integrations TinySwitch, Infineon CoolSET/CoolSET‑QR), but they change pinout/control behavior and require redesign. (st.com)

Detailed problem analysis

• What MIP2H2 is: a Panasonic monolithic offline switcher (primary‑side controller + internal HV MOSFET) in a DIP‑7 package for small flyback supplies (commonly found in TV standby/aux rails). (alldatasheet.com)
• Why true “replacements” are hard:
  • Vendor‑specific control schemes (PWM, burst/valley behavior, protection thresholds).
  • OCP/OVP/UVLO and current‑sense scaling differ by family and set the effective power limit.
  • Pinouts differ even when the package is DIP‑7/8, so PCB nets (VCC, FB, DRAIN, SOURCE) won’t line up.
• Practical consequence: If you cannot source a genuine MIP2H2, the next best path is either: 1) A vetted part from the same Panasonic MIP2x family after matching key parameters (drain voltage rating, current limit/RDS(on), VCC range, startup/burst behavior), or
  2) A functional redesign around another manufacturer’s integrated switcher.

Current information and trends

• Availability today (Nov 6, 2025): MIP2H2 is listed by repair‑part distributors (e.g., Sony PN 6‑708‑801‑01) and general suppliers in the U.S., so replacement with the exact part is still practical for repair. (encompass.com)
• Industry trend: For new designs, engineers increasingly choose more recent families (e.g., TinySwitch‑5, VIPer11/22, Infineon CoolSET‑QR) for better light‑load efficiency and EMI controls; these are not drop‑ins but are superior platforms for redesign. (power.com)

Supporting explanations and details

• Same‑family Panasonic options (verify before use):
  • MIP2Kx/MIP2F× series: DIP‑7 “IPD” parts for chargers/adapters. Some share a similar external application but differ in frequency, protections, and current limit. Do not assume direct compatibility; compare datasheets. (datasheetbank.com)
• Cross‑vendor functional alternatives (require changes):
  • ST VIPer22A/22AS (fixed‑frequency, integrated 800 V MOSFET); DIP‑8 pinout. Suitable for 5–15 W aux/standby supplies. (st.com)
  • Power Integrations TinySwitch‑III (e.g., TNY277P; 700 V MOSFET, ON/OFF control with jittering); DIP‑8C. Extensive design guides available. (power.com)
  • Infineon CoolSET QR (e.g., ICE2QR1065Z; quasi‑resonant, integrated MOSFET); DIP‑7 package but different pins/thresholds—close in function, not in pinout. (infineon.com)
• Key parameters to match when evaluating any substitute:
  • Drain voltage rating (≥ the original design’s requirement), current limit/RDS(on), VCC operating/startup range, switching method (fixed‑frequency vs burst/QR), protection behavior (OCP/OVP/OTP), and package creepage.
• PCB and magnetics impact:
  • Changing controller family often requires retuning the snubber/clamp, startup bias network, feedback optocoupler network, and possibly transformer primary inductance/turns ratio to meet regulation and OCP points.

Ethical and legal aspects

• Safety: You are working on mains‑referenced circuitry. Use an isolation transformer, respect creepage/clearance, and maintain agency approvals (UL/IEC) if the unit is returned to service. Substituting a different controller may void compliance unless re‑evaluated.
• Counterfeit risk: Buy from reputable distributors; many marketplace listings for obsolete IPDs are reclaimed or remarked devices. The Sony service P/N channel is often safer for repair parts. (encompass.com)

Practical guidelines

• For repair:
  • First choice: Install a genuine MIP2H2. It minimizes risk and time. (encompass.com)
  • If you must substitute within Panasonic: Pick a MIP2x datasheet, confirm pinout equality and similar current limit/startup specs, then bench‑verify. (datasheetbank.com)
• For redesign with an alternative IC:
  • Select a target family (VIPer/TinySwitch/CoolSET‑QR) based on required output power and EMI goals. Use vendor design tools (PI Expert, ST eDesignSuite, Infineon design notes) and follow their reference schematics. (power.com)
  • Modify: startup network (VCC/bias), feedback/compensation, clamp/snubber, and transformer. Validate at low line/high line, no‑load to full‑load, and across temperature.
• Bring‑up method:
  • Power primary via an isolation transformer and a series “dim‑bulb” limiter on first start; monitor VCC, drain waveform, and secondary rails. Step through dummy loads to confirm regulation and protection triggers.

Possible disclaimers or additional notes

• “MIP2H4 is a direct replacement”: I could not find any official Panasonic cross‑reference confirming MIP2H4 as a guaranteed drop‑in for MIP2H2; treat that claim with caution unless you can verify with a datasheet and compare thresholds/pinout. (No authoritative source found.)
• Differences between “charger”‑oriented MIP2K/F devices and TV standby controllers can affect startup and burst behavior; always check light‑load stability and no‑load consumption before committing. (datasheetbank.com)

Suggestions for further research

• Obtain and compare the original MIP2H2 datasheet with any candidate’s datasheet side‑by‑side (pin functions, VCC thresholds, OCP, RDS(on), frequency/control mode). (alldatasheet.com)
• If you redesign, consult the latest design guides:
  • ST VIPer22A/11 application notes. (st.com)
  • Power Integrations TinySwitch design guide (AN‑90). (power.com)
  • Infineon CoolSET‑QR application collateral. (infineon.com)

Brief summary

• Best and simplest: replace with a genuine MIP2H2 (readily available as of Nov 6, 2025). (encompass.com)
• Same‑family Panasonic parts may be close but are not guaranteed drop‑ins—verify carefully. (datasheetbank.com)
• Cross‑vendor alternatives (ST VIPer, PI TinySwitch, Infineon CoolSET‑QR) can substitute functionally with redesign effort. (st.com)

If you can share the device, output rails/power, and whether this is a repair or a redesign, I’ll propose the closest match and note the exact component/value changes needed.
