The 89883-304LF: Fastening is push-pull — no locking latch, so the mated pair relies on the post-solder joint and the header's retention for vibration resistance. In a telecom or industrial backplane where the board is bolted into a chassis, the push-pull interface is sufficient; in a portable or high-shock assembly, a locking-header variant is worth evaluating.
Right-Angle Termination and Board Routing
The 0.114" (2.90 mm) post length is long enough for a 1.6 mm standard PCB with through-hole solder — the tip protrudes past the bottom-side solder fillet for a visible inspection. The blue glass-filled thermoplastic housing (UL94 V-0) holds up in equipment that requires a flame-rated enclosure.
