Push-pull fastening means it's a friction-lock mate — no latch, so it's fine for low-vibration environments but not for automotive or heavy machinery. Tin-on-tin mating finish keeps the cost down but limits the connector to a low number of mating cycles before fretting corrosion starts. For a product that gets mated once at build and then stays connected, tin is fine. Tin wets well with standard lead-free solder profiles, and the PPS housing handles reflow temperatures without distortion.","metaTitle":"4-176891-2 TE Connectivity Header SMD 12POS 1.25mm Pitch","metaDescription":"TE Connectivity AMP Connectors Fine Pitch header, 12 positions, 1.25mm pitch, shrouded 4-wall, SMD, tin contacts, 0.5A, 50V.
