The 1-1888381-3: RoHS3 compliant per TE's current material declaration — no restricted substances above the threshold.
This header mates with AMP-Latch IDC socket connectors that accept 0.100" pitch ribbon cable — the latch lock/eject hooks engage the socket's locking ears for a positive retention. A keying slot in the housing prevents mis-mating with non-keyed counterparts — confirm the mating socket has the matching keyway profile.
The mating half is an AMP-Latch IDC socket connector (e.g., 1-746285-3 or similar) that accepts 0.100" pitch ribbon cable and has latch-compatible locking ears. Confirm the keying slot alignment before ordering.
Yes, it is listed as ROHS3 Compliant by TE Connectivity.
Yes, the housing includes a keying slot to prevent mis-mating with non-keyed connectors.
