It is a board-to-board or cable interconnect, rated 15 A per circuit at 500 VAC, with tin-plated contacts on both the mating and post sides. The header is fully shrouded with a 4-wall design and uses a locking ramp for positive retention when mated with the matching Universal MATE-N-LOK receptacle housing. ## What the ratings mean for the fit The 6.35 mm pitch and 3-position count are the first fit check — this header matches a 3-circuit BOM line on a board footprint spaced for 0.250-inch centers. The 15 A per circuit rating is bus-level current for a connector this size; each power blade carries enough current for a main DC rail or a motor drive line, not a signal trace. The 500 VAC voltage rating gives ample headroom for 240 VAC or 480 VAC industrial equipment without creepage concerns across the 6.35 mm pitch. The shrouded 4-wall design protects the male pins from bending during handling and mating — important for field-serviceable assemblies where the header is exposed. The locking ramp provides an audible click when fully mated, which confirms the connection is seated under vibration; this is a standard feature on the Universal MATE-N-LOK series and mates with the corresponding ramp on the receptacle. The UL94 V-0 glass-filled thermoplastic housing means this connector is rated for use inside equipment enclosures where flame retardance is required. The operating temperature range of -25°C to 85°C covers most indoor industrial and automotive cabin environments, though it does not extend to under-hood or outdoor direct-sunlight applications without derating. ## Termination and mounting The 173925-1 supports both press-fit and solder termination through the same through-hole footprint. The press-fit option is suited for backplane or solderless assembly where rework or high-reliability connections are needed; the solder option is the standard through-hole method. The contact post length is 0.189 inches (4.80 mm), which fits standard 1.6 mm PCBs with room for the solder fillet.","metaTitle":"TE 173925-1 Universal MATE-N-LOK Header, 3 Pos, 6.35mm, 15A","metaDescription":"TE 173925-1 Universal MATE-N-LOK header, 3 positions, 6.35mm pitch, 15A, 500VAC.
