Frequently Asked Questions

How do I identify the correct Molex terminal for my connector?

Cross-reference the part number 19434-0003 in the Molex online catalog (molex.com) to verify the terminal specifications, compatible housings, and required crimp tool. The Molex catalog provides the complete terminal datasheet including wire range, current rating, crimp tool specification, and compatible housing part numbers. If the terminal part number is not visible on the original terminal, identify the connector housing part number and cross-reference to find the compatible terminal.

What crimp tool is required for Molex 19434-0003?

Molex specifies a dedicated crimp tool for each terminal series. Cross-reference 19434-0003 in the Molex catalog to identify the required crimp tool part number. Using the wrong crimp tool produces an incomplete crimp that fails Molex’s pull-out force specification. For professional automotive harness repair, use the Molex-specified ratchet crimp tool with the correct die.

Can I use these terminals to repair a damaged Molex connector?

Yes. Repair procedure: (1) use a terminal extraction tool to remove the damaged terminal from the Molex housing; (2) cut the wire behind the damaged terminal; (3) strip the wire to the length specified in the Molex terminal datasheet; (4) crimp the new terminal using the correct Molex crimp tool; (5) insert the new terminal into the housing until the locking lance clicks. Verify terminal seating with a pull-test before reassembling the connector.

Typical Applications
