The 4-103325-0-19: The post finish is tin-lead at 100.0 µinch (2.54 µm) — not RoHS-compliant. This matters for legacy BOMs that require tin-lead solderability for rework or for RoHS-exempt applications.
Unshrouded push-pull fastening — the mating receptacle slides on and off without a latch. This is a breakaway header: if the cable snags, the receptacle pulls free rather than ripping the pins off the board. Termination is solder through-hole.
