What This Header Is
The FCI 65863-015LF is the 16-position member of the Quickie™ series — a dual-row 0.100" (2.54 mm) pitch board-to-cable header with a 4-wall shroud and a dedicated keying slot that prevents mis-mating in multi-connector assemblies. Push-pull fastening means the mating half snaps in without tool actuation; the shroud locks the receptacle positively and keeps the housing aligned under vibration or cable pull. Contact material is phosphor bronze, with bifurcated plating: 30.0 µin (0.76 µm) gold on the mating face and 100.0 µin (2.54 µm) tin on the solder post. The thick post-side tin ensures reliable solderability and wetting; the gold mating finish protects the contact interface across repeated mate/de-mate cycles. The insulation body is black thermoplastic rated UL94 V-0.
Where It Fits in the Build
16 positions across two rows at 0.100" pitch — the canonical Quickie footprint that matches the 0.100" row spacing. The 0.640" (16.26 mm) insulation height gives the header enough standoff to clear conformal coat or underfill in board-to-cable applications. Through-hole mounting with 0.150" (3.81 mm) post length accommodates standard PCB thicknesses; the 0.230" (5.84 mm) mating length positions the contact engagement deep enough for reliable wipe.
Sourcing Reality
Status is Active — no LTB notice or EOL notice listed. Quoted to order against BOM quantity; the tray package is the standard pack for this part, not tape-and-reel. The base product number is 65863 — lower-position-count variants in the same series may cover other BOM lines and consolidate connector SKUs to one family. No official successor listed; the Quickie family is a widely second-sourced FCI/Amphenol standard, so a pin-compatible alternate from another franchised distributor is a viable conversation if you are managing single-vendor exposure.
