FFF CompatibilityThe package footprint and pinout assignments are fully compatible with GAQY214EH.Both parts use the standard 4-SMD Gull Wing package with equivalent physical outer dimensions.Continuous load current is slightly lower (120 mA vs 130 mA) and maximum on-state resistance is higher (35 Ohms vs 25 Ohms).Housed in a 6-pin SMD package rather than a 4-pin SMD package, requiring a complete footprint redesign.Physical package size is larger (6-SMD vs 4-SMD) and uses more pins.Input-to-output isolation voltage is lower (3750 Vrms vs 5000 Vrms), though output load ratings are superior.
AI Summary

GAQY214EH by APSEMI: Solid State Photo-Coupled Relay (Photorelay) SPST-NO (1 Form A) 4-SMD.

An excellent high-reliability drop-in option from Panasonic that perfectly matches the package dimensions, pin layout, 400 V load voltage, and 5000 Vrms isolation rating. The only minor trade-offs are a slightly lower continuous load current and a slightly higher maximum on-resistance.

  • Pin-compatible drop-in with matching 4-SMD layout (Pin 1 Anode, Pin 2 Cathode, Pin 3/4 Load)
  • Equivalent 5000 Vrms high-isolation voltage rating
  • Maintains the identical 400 V maximum load voltage ceiling
  • Slightly lower continuous load current: 120 mA vs 130 mA
  • Higher maximum on-state resistance: 35 Ohms vs 25 Ohms

An industrial-grade performance alternative that offers vastly superior load current capabilities and much lower on-state resistance. However, it requires a PCB layout redesign due to its larger 6-SMD footprint and features a lower isolation rating of 3750 Vrms.

  • Significantly higher continuous load current rating: 250 mA vs 130 mA
  • Significantly lower maximum on-state resistance: 8 Ohms vs 25 Ohms
  • Identical 400 V maximum load voltage ceiling
  • Larger 6-SMD footprint requires PCB redesign
  • Lower isolation rating: 3750 Vrms vs 5000 Vrms

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
