The 4.20mm pitch is the same across the Mini-Fit family, so the footprint and mating interface are consistent whether you're using a 2-, 4-, or 10-circuit housing. The dual-row layout puts 5 contacts per row, which keeps the connector body compact for the circuit count. No secondary locking mechanism needed here; the TPA2 name refers to the terminal position assurance feature built into the housing, which locks each crimped contact in place after insertion. The glow wire compliant rating means the housing material resists ignition under fault conditions. The nylon insulation handles thermal cycling.
What Doesn't Come in the Bag — Contacts Are Separate
The female socket contacts (Molex Mini-Fit Jr. crimp terminals, series 44476 or similar) must be ordered separately. You'll also need the appropriate crimp tool — typically a hand tool or a pneumatic applicator for production runs. Wire gauge range for the Mini-Fit TPA2 system is 18-24 AWG depending on the terminal variant. Always confirm the terminal part number against the wire size and current requirement before committing the BOM.
