The 4-wall shrouding and keying slot protect the pins from damage and prevent mismating with non-keyed receptacles. A mounting flange on each end gives the board assembler a mechanical anchor — useful when the cable assembly will see tugging or vibration after the connector is mated.
Active Production — No End-of-Life Concern Here
No successor or replacement has been issued — this is the current-production part for the AMP-Latch 20-position, 2.54mm-pitch header family. Note the RoHS status: this variant is listed as RoHS non-compliant due to tin-lead plating on the solder posts. If your BOM requires full RoHS compliance, check the 102156-3 or other lead-free siblings in the same series.
