Single-contact compression spring for board-level interconnect
The Z01D-4C7J1-11000-E000 is a single-contact compression contact from Amphenol ICC (FCI), non-gendered, designed for surface mount termination. The copper alloy spring provides a compliant interconnect between parallel PCBs or between a board and a test fixture, accommodating stack-up tolerances without a rigid pin.
Comparing sibling spring contacts
The Z01E-4C7J1-11000-E000 adds gold plating 8.00µin over the copper alloy, which improves corrosion resistance and contact resistance stability over many mating cycles. The Z01G-4C7J2-11000-E000 is identical in material and packaging but carries a different part number — likely a plating or stroke variant. The Z02D-4F7L1-11000-E000 is the same single-contact compression spring but offered in tape-and-reel packaging for automated SMT assembly. If your pick-and-place line needs reel feed, the Z02D variant saves a handling step.
