Replacement for obsolete Mouser parts (152-3415, 512-LM324AN) #11

I'm gathering the parts for a card, using the BOM file in Mouser, but there are 2 items that are marked as obsolete, so I'll need replacements.

  1. The 15 pin D-SUB socket (152-3415)
  2. The amplifier chip U5 (512-LM324AN)

I tried looking for a replacement DSUB connector by selecting all the attributes and looking for similar, and the search came up with 20 items. Can I just grab the cheapest one? :P

And can the amp chip be replaced with this one: https://www.mouser.co.il/ProductDetail/Texas-Instruments/LM324AN?qs=KaAwwOlwapuGsi7hHRxlkw%3D%3D ? I noticed that it have a bit different "Output Current per Channel" value of 20mA, vs 40mA in the original part.

i've swapped in some new parts in the BOM. the TI LM324 should work fine. the d-sub connector is not critical but you must check the distance between the mounting holes on the footprint and the panel edge -- it should be about 9.5mm. some d-subs are "stubby" and won't work.
