The 0039299145: The tin-plated solder tails (100µinch) are standard for wave-solder assembly.
This header mates with Mini-Fit Jr 5566 receptacle housings. The 4-wall shrouding guides the receptacle into alignment and protects the pins during blind-mate assembly. Termination is solder — the 0.138-inch (3.50mm) post length fits standard 1.6mm-thick PCBs with through-hole plating. The square contact shape provides reliable solder fillet formation.
The header has 14 circuits in a dual-row layout on a 4.20mm pitch, with a row spacing of 4.20mm. This matches the Mini-Fit Jr receptacle family for a direct board-to-wire connection.
Yes, it is ROHS3 compliant per the manufacturer's listing.
