It carries 8 A per contact at 600 V across a dual-row 3.00 mm pitch, with a 30.0 µ\" gold mating interface that handles repeated mating cycles in corrosive or high-vibration environments. The shrouded 4-wall housing with locking ramp and board lock provides positive retention and shear-force resistance during assembly and field service. ## Ratings and what they mean for the fit The 8 A per-contact rating at 600 V is the headline power spec. The 3.00 mm pitch gives enough creepage for the 600 V rating. The 30.0 µ\" gold on the mating side is a robust industrial-grade plating — not a flash-gold or tin surface. It supports hundreds of mating cycles without fretting corrosion, which matters for equipment that sees periodic disconnection during maintenance or reconfiguration. The tin-plated solder tails (100.0 µ\") are standard for through-hole wave-solder processes. The -40°C to 105°C operating range and UL94 V-0 liquid crystal polymer housing confirm this header is rated for under-hood automotive and sealed industrial enclosures where flame retardance and thermal cycling are requirements, not options. ## Mating and termination This header mates with the matching Micro-Fit 3.0 receptacle housing (female, crimp-terminal style). The locking ramp on the 4-wall shroud engages the receptacle latch for an audible click — the connection stays mated under vibration without a secondary lock. The through-hole right-angle orientation places the mating face parallel to the PCB, suited for board-edge or low-profile enclosure layouts. Termination is solder to the PCB — the board lock feature holds the header in place during wave solder, preventing skew from the cable strain that follows in the harness assembly. ## Sourcing and lifecycle The 430451602 carries an Active lifecycle status with ROHS3 compliance. No official successor or cross-reference is on record — the Micro-Fit 3.0 series is a mature, broadly used platform, so the mating half and footprint are well established in existing BOMs.","metaTitle":"Molex Micro-Fit 3.0 430451602, 16-circuit R/A Header, 8 A","metaDescription":"Molex Micro-Fit 3.0 430451602 right-angle header, 16 circuits, 3.00 mm pitch, 8 A per contact, 600 V, gold mating, board lock, UL94 V-0.
