5556 Datasheet, PDF (1/2 Pages) Molex Electronics Ltd. – Mini-Fit® TPA (Terminal Position Assurance) Plugs and Receptacles

Mini-Fit^® TPA plugs and receptacles are ideal for high-vibration and high-current
applications requiring a redundant terminal retention feature
Mini-Fit^® TPA plugs and receptacles utilize a visible “TPA pin” that when engaged,
will ensure that the terminal is fully seated in the housing and that the terminal will
not back out of the housing during mating or when in use. Mini-Fit TPA connectors
also feature an optional 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. Also, no additional crimp tooling is needed. Mini-Fit TPA
products are available in wire-to-wire and wire-to-board configurations with circuit
sizes ranging from 2-16 and accommodating 16-28 AWG wire.
FEATURES AND BENEFITS
• TPA lock inserts into plug and receptacle
housings to ensure that terminals are fully
seated and guarantees that the terminals
will not back out
• Optional CPA (Connector Position
Assurance) key prevents accidental
unmating
• Up to 13.0A per pin for increased
current carrying capabilities
• Offered in wire-to-wire and wire-to-
board configurations; headers
available in mounting pegs or
screw-mount flanges
• No new tooling required
