    I'm tryin to find a replacement for G5A-237P 12vdc relay in a yaesu ft-8900. I'm coming up short everywhere and no response from mouser on an alternative . So I thought I'd ask the collective here if they knew.

    thanks so much,

    Obviously, you are not aware to Search ALL of the Major Electronics Distributors:
    Mouser, Digi-Key, Newark/MCM, Avvid, Farnell/element14, Allied Electronics, Future.
    ** I started with Allied in 1968, before Radio Shack bought their stores/consumer division. **

    Electronics Parts Manufacturer’s have Preferred Distributors or Exclusive Relationships.
    I prefer Digi-Key, founded by a Minnesota radio amateur, for my parts source.

    For the Yaesu FT-8900 Transceiver, OMRON was the OEM Relay supplier.
    The G5A-series of Low Signal Relay (up to 2 Amps) was used.
    OMRON Electronics G5A-237A-DC12

    OMRON G5A-series Datasheet here:

    OMRON Electronics G5A-237A-DC12 , DPDT, Non-Latching, Semi-sealed
    DISCONTINUED September 2010
    The OMRON EOL Notice (on Mouser site) recommended their G6S Series
    (Conditional Replacement)
    NOTE : These Relays are Surface Mount

    Digi-Key recommends two (2) Substitutes,
    Potter & Brumfield (TE Connectivity) Relays.
    MIGHT NOT Be Plug-N-Play Replacement for the Yaesu FT-8900 PC Board Layout

    I've no training in this just what I can figure out along the way or if someone takes the time to school me. To me it looks like the package is bigger 20mm to 16mm . Control functions look correct .
    This V23105A5303A201 looks close to the pin spacing than the other one.
    i appreciate your help and if there is a tutorial on finding components please point me in that direction.

    Google the service manual, get the part number from the parts list, then call or e-mail Yaesu parts department and ask if it’s available. Many of the parts like relays and potentiometers have been used in multiple models so it’s quite possible they have it.

    YES. Until 2019, China has Actively purchased Surplus Electronic Parts (discontinued, End-of-Life) and Electronic / Computer equipment discarded/trashed. Metals recycled, remainder burned (toxic hazard).

    In Chicago area there were two or three warehouses that purchased off-lease computers, former cellular phone site equipment, and solicited Electronics test equipment (paid by pound).
    After shipping to China (in formerly empty cargo containers) … hundreds of workers stripped equipment to modules or valuable ($$) components … that were then sold on Alibaba and eBay.

    You have to be responsible for your own education / self-improvement.
    Self-Reliance appears to no longer be taught in 21st century.

    Funny self reliance is not really a thing. If we were all self reliant the human race would have died out long ago . And elmers would not be a thing.

    forums are made up of people helping people.
    some people help their wounded ego by putting others down, maybe kicking them when down.
    routine here on the zed, just watch.
