Any suggestions for a replacement for Motorola MDA 922-6 bridge rectifier? There are 3 of them in the power supply of this HP counter. Not a critical application just thought someone might know a good direct drop-in. I'm not seeing anything packaged similarly. Thanks

Just pick a 2A through hole bridge rectifier (cheap and plentiful) and arrange and bend the wires so that they would solder onto the pads.
e.g. https://www.digikey.ca/product-detail/en/vishay-semiconductor-diodes-division/2W005G-E4-51/2W005G-E4-51GI-ND/2139739
Hopefully there is enough room to mount with the height this requires compared to the original.

A quick search showed on eBay a similar to the original rectifier as "vintage rectifier", with matching price, so I wonder if they are still produced.

Good luck, Peter

If all else fails, and you are not concerned about appearance or cosmetics, you can use 4 2A rectifiers for each bridge assuming there is nothing *special* about the way the originals were packaged. But you should be able to find a suitable replacement through hole, as noted
