What this header is and where it sits in the series
The Molex 430450215 is a 2-position, dual-row male-pin SMT header from the Micro-Fit 3.0 43045 series — 3.00 mm row spacing with a locking ramp and board lock feature on the housing. All circuits are loaded; contacts are brass with 60.0 µin (1.52 µm) matte tin plating on the mating interface and solder tails. The insulator is black glass-filled LCP rated UL94 V-0.
What the key ratings mean for the BOM fit
8 A per circuit at 600 V puts this firmly in power-header territory — it will carry discrete power runs or bus rails in automotive, industrial, and medical instrument applications where the 3.00 mm pitch keeps the footprint compact without resorting to a larger connector family. Tin plating at 60.0 µin is the standard commercial grade for the series — the matte finish is adequate for signal or power mate/unmate in an industrial environment. The insulation height of 0.390 in (9.91 mm) is the dimension to watch when stacking this header under a moulded cover or routing wires past the connector — confirm the enclosure geometry clears the board-lock features without interference. -40°C to 105°C operating range covers the automotive and industrial temperature bands; the LCP glass-filled body does not soften at the upper end, but as with all SMT board-mount headers, the solder joint thermal cycling budget should be evaluated against the application's power-on hours.
Mating half and termination
This is the male-pin board-mount half — it mates with the matching Micro-Fit 3.0 female receptacle housing in the same series. The locking ramp on the header engages the housing latch for positive retention. Termination is SMT solder — the board-lock features hold the header in place during reflow paste deposition and the thermal ramp, which is the primary reason to specify this variant over a non-board-lock equivalent.
Applications and compliance
Listed for Automotive, General Purpose, Industrial, Medical, and Telecommunications — the UL94 V-0 flammability rating and 600 V rating are the relevant credentials for industrial control panels and medical device power-distribution boards where the enclosure standard demands it. ROHS3 Compliant — no restrictions for European or Asian industrial/automotive supply chains. No REACH or UL黄卡 listing appears in the record for this specific variant, so for medical device sub-assembly submissions, confirm the UL file number with Molex directly.
