content: Ex. 12 - 16 AWG wire, strip, crimp on bare terminal, insert terminal legs into PCB thruhole, solder.I know this connector category is generally supposed to be more reliable than bare wire-to-board, IDC, poke-home, etc.But then why are products like Molex Solder Right discontinued? Is there a hidden reliability problem? Or just a business reason (moving out of low margin commodity products)?Examples:https://www.digikey.ca/en/products/detail/molex/1718920100/4946742https://www.digikey.ca/en/products/detail/molex/1722490100/4946694On a side note, is there an even more reliable design category for compact permanent WTB (space/aero/mil perspective)?

content: Huh? The examples you give of “discontinued” products aren’t even discontinued. One of them is active, the other one “Discontinued at Digi-Key”, which simply means Digi-Key has decided to stop stocking that item.

content: Every Solder-right product family page is dead or has dead links, and no longer shows up in the wire to board solutions page.Ex:https://www.molex.ca/molex/products/family/solderrighthttps://tools.molex.com/molex/products/family/solderright

content: Links work for me. Seems like you have a firewall/provider problem.

content: Your links don't work properly, but this onehttps://www.molex.com/en-us/products/part-detail/1726770100seems to. Maybe Molex have just been reorganising their site. I see the magic word "active" on that page.

content: its been a total mess for parts in the last long time nowthe uh... zero stock pile time on delivery so we don't need to sell surplus ever in case people stop ordering because there is a small chance of design change which might cost money thing has not worked out with the 'unforeseeable' problems (seeing past 1 quarter is not possible according to modern MBA teachings)?

content: Molex have indeed recently redone their website. Seems like there is some weirdness with the search, and presumably a lot of links have changed. That would explain the 'dead'/incorrect links the OP is seeing.

content: Don't solder, just crimp. Solder causes the wires to break.

content: you missed it, its a way to solder a crimped wire to the PCB. Like a pin that you crimp to the wire that is soldered to the PCB.so you don't have solder in the strands of wire but you have a soldered connection to the PCB.

content: Quote from: openyk on May 06, 2023, 07:50:06 pmI wouldn't read anything into that. Molex's website has been a hot mess for a while. Between the ham-fisted website reorganization and the prior (I don't know when) renumbering of all their parts (hence the "Engineering/Old PN" listed on many products), links to and within the website have been unreliable for ages.
