The Amphenol FCI 10103594-0001LF is a USB 2.0 micro-B receptacle — the 5-contact, 1-port, horizontal-mount version that mates with the standard micro-B plug found on countless portable devices, data cables, and embedded modules. It sits in the 10103594 base series, which covers the common micro-B footprint with variations in mounting height and orientation. The shell is shielded with a steel and stainless steel wrap, and the contacts carry gold finish. The 1.8 A per contact rating and 100VAC voltage spec put it in the standard USB power-delivery range for 5 V bus-powered peripherals.
The solder retention feature adds hold-down tabs that reflow with the signal pins. The mounting feature is horizontal, meaning the USB opening faces the board edge.
Rated for 10,000 mating cycles — that is an order of magnitude above the typical 1,000-5,000 cycles for a consumer-grade micro USB connector. The gold contact finish supports that duty, resisting fretting corrosion through repeated insertions. For a field-service tech or a product that sees daily cable connects (test equipment, handheld instruments, docking stations), this connector is built to last years of regular use without the contact wear that causes intermittent disconnects on standard parts.
Both are 5-contact, shielded, USB 2.0 micro-B receptacles with the same 1.8 A/100VAC rating and 10,000-cycle life. The difference: the 10103593-0001LF uses a mid-mount design, where the connector body sits partially recessed into a cutout in the PCB, lowering the mated profile above the board surface. The 10103594-0001LF is a standard horizontal mount — the body sits entirely on top of the board. Choose the mid-mount version when the enclosure height above the PCB is tight; stick with the standard horizontal mount for a simpler board cutout and easier hand-assembly inspection.
