Engineering Selection Recommendations
The TE Connectivity 61868-1 is the manufacturer-recommended substitute for the obsolete Molex 0191951007. Both components share identical stud size (1/4), mounting configuration (Free Hanging In-Line), and non-insulated design. Both maintain RoHS compliance and unlimited moisture sensitivity ratings, ensuring regulatory compatibility in current applications.
The primary difference lies in termination capability: the Molex part supports both crimp and piercing termination, while the TE Connectivity substitute provides crimp termination with serrated termination features. Wire gauge specifications differ in notation (10380-52480 CMA versus 6-10 AWG), but both accommodate similar conductor sizes within standard industrial ranges.
The TE Connectivity 61868-1 is currently in active production with substantial inventory availability (12,698 pieces), providing supply chain reliability for replacement and new applications.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 61868-1 directly replace the Molex 0191951007 in existing assemblies?
A: Yes, for applications requiring crimp termination. Both parts share identical 1/4 stud size and Free Hanging mounting configuration. If piercing termination is required, compatibility must be verified against specific application requirements.
Q: What is the significance of the wire gauge difference between 10380-52480 CMA and 6-10 AWG?
A: Both specifications define the conductor size range the terminal accommodates. The 6-10 AWG rating of the TE Connectivity part covers standard wire gauges used in industrial and automotive applications. Verify your specific wire gauge falls within this range before substitution.
Q: Are there compliance differences between the two parts?
A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) ratings. The Molex part is RoHS3 compliant, while the TE Connectivity part is RoHS compliant. Both meet current regulatory requirements for new designs and replacements.
Q: What is the impact of the thickness difference (0.062" versus 0.040")?
A: The TE Connectivity part is thinner. This difference may affect mechanical fit in space-constrained applications. Verify clearance and mounting compatibility in your specific assembly before implementation.
Q: Does the serrated termination feature on the TE Connectivity part affect compatibility?
A: Serrated termination improves mechanical grip and electrical contact consistency. This is a performance enhancement that does not negatively impact compatibility with standard 1/4 stud applications.
Q: What packaging format is the TE Connectivity substitute available in?
A: The TE Connectivity 61868-1 is supplied in Cut Tape (CT) packaging, suitable for both manual and automated assembly processes.
