Pin Count, Pitch, and Orientation — BOM Fit Check
The 102160-3: The keying slot and mounting flange add mechanical registration and panel-securing options — useful when the header must resist cable strain or align with a cutout in the enclosure.
Contact Plating and Current — Signal-Duty Ceiling
This is a signal-level current ceiling — the 1 A limit accounts for the contact density and the housing's thermal rise in still air. For multi-conductor bundles, derate per the application note to stay within the UL94 V-0 housing's temperature limit.
Sourcing and Lifecycle — Active, Quoted to Order
The base product number is 102160, so mating receptacles and crimp terminals in the AMP-Latch family share the same prefix — useful for building a complete harness from one series.
