The surface-mount solder termination is compatible with reflow assembly, and the pick-and-place feature means the part ships on Tape & Reel for automated placement — no manual handling required for volume builds. Gold flash on the mating contacts provides a corrosion-resistant interface for moderate mating-cycle duty — think a few hundred cycles in a production test fixture or a field-serviceable module that isn't swapped daily. For higher cycle counts, a thicker gold plate would be needed. The base product number 20021321 covers the full family — the suffix -00040C1LF specifies the 40-position, gold flash, SMT, Tape & Reel variant. No direct pin-compatible equivalent from another manufacturer is listed; the Minitek127 series is proprietary to Amphenol ICC (FCI). As a receptacle, it mates with a matching Minitek127 1.27mm pitch header — typically a dual-row, surface-mount or through-hole header with the same 40 positions and 1.27mm row spacing. The push-pull fastening means the pair is held together by contact friction and alignment; no secondary latch is present. Termination is solder-only — the SMT pads are reflowed to the PCB.","metaTitle":"20021321-00040C1LF Amphenol ICC (FCI) Minitek127 40-Pin SMT","metaDescription":"Amphenol ICC (FCI) Minitek127 1.27mm pitch, 40-position, dual-row board-to-board receptacle.
