Mini-Fit® TPA Plugs and Receptacles


Mini-Fit® TPA plugs and receptacles handle up to 13 A and are ideal for high-current applications requiring a redundant terminal retention feature


Molex's Mini-Fit® TPA plugs and receptacles utilize a highly visible "TPA pin" that indicates when a terminal is fully seated in the housing and ensures that the terminal will not back out of the housing during mating or when in use. Mini-Fit TPA connectors feature a connector position assurance (CPA) key, ensuring that the male and female connectors cannot be accidentally disengaged. The Mini-Fit TPA product family accepts all standard Mini-Fit crimp terminals, further reducing design and qualification efforts. Mini-Fit TPA products are available in wire-to-wire and wire-to-board configurations, with various circuit sizes ranging from 2- to 16-position accommodating 16 to 28 AWG.
