33 of 34 positions — the keying slot is deliberate
The 1761664-2: This AMP-Latch header carries 33 loaded positions out of a 34-position housing. The unloaded 34th position is a keying slot — it prevents mismating with the wrong AMP-Latch IDC socket, not a missing pin.
Gold at this thickness supports repeated mating cycles — 100 or more — without the corrosion or resistance rise that tin would show in a field-service environment. The contact base is phosphor bronze, a standard spring alloy that holds its beam force over temperature and time.
Active production — no LTB watch needed
The lifecycle status is Active.
This is a through-hole solder header with a shrouded 4-wall housing. The push-pull fastening type means it mates with the standard AMP-Latch IDC socket without a latch lock — the shroud guides the socket into alignment, and the keying slot prevents a wrong-coded socket from seating. The insulation height is 0.350" (8.89mm), and the mating contact length is 0.240" (6.10mm) — enough to fully engage the socket contact beam. The post length is 0.102" (2.60mm), suited for a standard 1.6mm PCB thickness.
