The Molex 10142963-104KLF is a 4-circuit male pin header from the Minitek MicroSpace 1.80mm series, designed for board-to-cable/wire interconnects in automotive, general purpose, and industrial applications. It carries a 1.80 mm pitch and is rated 4 A per circuit — the pitch and current pair well for signal-level power distribution in tight harness layouts where a 2.00 mm header would crowd the board edge. The right-angle SMT orientation places the mating face parallel to the PCB, which suits low-profile enclosures and cable exits along the board edge.
Mounting and retention
The header is shrouded on all four walls, which protects the pins during mating and prevents stubbing against the receptacle housing. A latch holder fastening system locks the mated pair — the latch clicks into place and holds under vibration without relying on a separate clip. Board guide and solder retention features on the SMT package help align the part during reflow and keep the solder joints from lifting under cable strain. The 4 A rating at the stated temperature range is derated above 85°C per the manufacturer's curve; the tin-on-tin contact finish handles the mating cycle count typical of a harness that mates once at assembly and stays connected.
Compliance and lifecycle
The housing is rated UL94 V-0, so it meets the flame requirement for equipment inside an enclosure. The operating temperature range of -40°C to 130°C covers underhood automotive and industrial cabinet environments. ROHS3 compliance is on record, which clears the part for EU-regulated markets. The manufacturer lists an Active lifecycle status — no end-of-life notice, no last-time-buy window.
Position count comparison
The closest sibling in the same series is the 10142963-106KLF, a 6-position variant at the same 1.80 mm pitch, 4 A per circuit, tin-on-tin plating, and right-angle SMT mounting. The only functional difference is the circuit count — 4 positions vs 6 positions. If the BOM calls for 6 circuits, the 106KLF is the drop-in match; if the board layout has space for only 4, the 104KLF fits without changing the footprint or the mating receptacle family.
