The Z003-007L1-11001: This is a single-circuit compression contact from Amphenol ICC (FCI)'s spring-loaded contact family, designed to press against a flat pad or busbar rather than mate with a receptacle. The phosphor bronze spring provides the contact force; the gold finish (8.00 µinch) keeps the interface stable through repeated mating cycles. At 3.3 mm compressed height, it fits into tight board-to-board or board-to-battery standoffs — common in handheld test fixtures, battery contacts, and programming jigs where a low-profile, reliable interconnect is needed. Because it's non-gendered, the mating surface is simply a solder pad or plated area — no housing or latch required. This makes it a good choice for applications where the contact is accessed infrequently, such as a firmware programming point or a battery terminal.
What the gold thickness and spring material mean for field reliability
In a field-service programming fixture cycled weekly, that's years of reliable contact before resistance drift becomes a concern. If the application sees high vibration or needs a higher spring force, the stainless steel peer Z00F-4G7L1-11000 is a direct alternative with the same gold thickness and footprint.
