4.20 mm pitch dual-row header for wire-to-board power
The 1724479604 is a 4-position, dual-row shrouded header from the Molex Mini-Fit Jr 172447 series, designed for board-to-cable/wire applications. The 4.20 mm pitch sets the board footprint and the per-contact current ceiling — at the rated voltage of 600 VAC/DC, the limiting factor is the wire gauge used, not the header itself.
Through-hole termination and board layout fit
Termination is through-hole solder, with a post length of 0.140" (3.56 mm) and tin-plated posts (100.0 µin thickness) for reliable soldering. The 0.500" (12.70 mm) insulation height provides clearance above the board for the mating receptacle and wire strain relief.
Compliance and sourcing reality
This header mates with standard Mini-Fit Jr. receptacle housings (e.g., 39-01-2040 or equivalent 4-circuit dual-row) using crimp terminals such as 39-00-0039 (18-24 AWG) or 39-00-0047 (16-20 AWG).
