The 0039296028: The header uses a dual-row layout with 0.165" (4.20mm) row spacing. Mates with the standard Mini-Fit Jr receptacle housing (e.g., Molex 39-01-2020 or equivalent 2-circuit receptacle) using the matching crimp terminal (Molex 44476-1112 or 44476-1111 for 18-24 AWG).
The part is ROHS3 compliant.
The row spacing is 0.165" (4.20mm). The pitch between contacts within a row is the standard Mini-Fit Jr 4.20mm pitch.
No official direct replacement is listed. The 0039296028 is the active 2-position Mini-Fit Jr header with gold contacts. Alternatives with tin contacts or different plating thickness exist within the same series but are not pin-compatible without a BOM change.
