It carries a 6.35 mm pitch — wide enough to handle the 15 A per-circuit rating without crowding the board layout. The through-hole mounting accepts either press-fit or solder termination, giving the assembly line flexibility between reflow and backplane press-in processes. The housing is a glass-filled thermoplastic rated UL94 V-0, and the locking ramp provides positive retention against vibration. ## Ratings and what they mean for the fit The 15 A per-contact rating is the headline number, but the tin-on-tin contact finish (78.7 µin on the mating side, 20.0 µin on the post) governs the real duty cycle. Tin-plated contacts are suited for a moderate number of mating cycles — think a PSU harness that mates once at build and stays mated, not a field-service connector that sees frequent disconnect. The 500 VAC rating pairs with the 6.35 mm pitch to give enough creepage for that voltage without requiring a conformal-coated board. The locking ramp engages with the matching receptacle housing to prevent the pair from backing out under cable strain or machine vibration. ## Termination and mounting The header lists both press-fit and solder as termination options. The press-fit variant is the one that stands out — it lets you seat the header into a plated through-hole without a wave solder step, which is common in backplane or power-distribution boards where rework access is limited. The through-hole mounting with a 0.189\" post length gives a solid mechanical anchor before the press-fit interference holds it. The 4-wall shrouding protects the male pins from being bent during handling or blind mating. ## Sourcing and lifecycle The 173924-1 carries an Active lifecycle status from TE Connectivity — no end-of-life notice, no last-time-buy clock. It is RoHS3 compliant.","metaTitle":"TE 173924-1 Universal MATE-N-LOK Header, 2 Pos, 15A","metaDescription":"TE Connectivity 173924-1 Universal MATE-N-LOK header, 2 positions, 6.35mm pitch, 15A, tin-plated, locking ramp.
