It carries a 5.00 mm pitch and is rated for 20 A per circuit at 250 VAC, placing it firmly in the high-current power distribution class — not a signal-level interconnect. Silver plating on both the mating tab and the solder post is the right choice for a power application: lower contact resistance than tin at high current, though it will tarnish in corrosive environments if left unmated. The through-hole termination with a 3.50 mm post length gives a solid solder joint in a standard 1.6 mm PCB — no special hole depth needed. ## Mating and Fit The 5.00 mm pitch and 3-position count are the primary fit constraints — the latch holder on the header engages with the locking ramp on the receptacle for a positive lock.","metaTitle":"TE Connectivity 9-1971846-3 Header, 3 Pos, 5mm, 20A","metaDescription":"TE Connectivity 9-1971846-3 header, 3 positions, 5.00mm pitch, 20A, silver-plated contacts, shrouded, glow wire compliant.
