The Molex 1727670110 is a 10-circuit plug housing from the Mini-Fit TPA2 series, built on the standard 4.20mm pitch that defines the Mini-Fit footprint.
The TPA (Terminal Position Assurance) feature in the TPA2 series provides a secondary lock that confirms each terminal is fully seated before the connector is mated.
The snap-in feature holds the housing in place while the harness is routed and mated.
Glow Wire Compliance — What It Means
The housing material (PA66, nylon) is rated glow wire compliant. This means the connector meets the 850°C glow-wire test per IEC 60335-1, a requirement for household appliances and similar equipment where a hot component could ignite the plastic. For a harness builder, this simplifies compliance — no need to add a separate heat shield or secondary insulation at the connector interface.
