Position count and board footprint
The 430451807: 18 positions across two rows at 3.00 mm pitch — the circuit count is the primary BOM-matching fact here, not a headline current number. The right-angle orientation places the connector flat against the board. Check the housing standoff height and enclosure depth against the 0.290-inch (7.37 mm) insulation height.
Mechanical retention for high-vibration environments
The four-wall shroud and locking ramp add side-load retention at the mating interface — the shroud channels the plug engagement and the ramp locks it in place once seated. This combination is standard for automotive and industrial harness runs where vibration tries to unmate the connection. The square pin contact shape and the board lock together take the mechanical load off the solder joints during service or shock events.
Materials, flammability, and temperature range
Brass contacts with glass-filled liquid crystal polymer (LCP) housing meet a UL94 V-0 flammability rating — the material choice reflects the automotive and medical target markets on record. The -40°C to 105°C operating range covers the typical under-hood and industrial control enclosure envelope, and the LCP body handles reflow profile temperatures without warpage given its glass fill.
Sourcing
Active and ROHS3 Compliant. No official cross-reference or successor is listed in this series for this position count — confirm your BOM position count and verify the matching Micro-Fit 3.0 receptacle housing before committing. Sourced to order against the BOM quantity per RFQ.
