• Contact Finish: Both specify gold mating surface finish
• Ingress Protection: Both meet IP50 dust protection rating
• Cable Opening Tolerance: Both accommodate 0.209" ~ 0.256" (5.30mm ~ 6.50mm) cable diameters
• Insert Material: Both utilize Polyetheretherketone (PEEK)
• Compliance: Both are ROHS3 compliant with MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC65A and K11MA7-P04LJG0-6560 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent substitution in applications where the specified parameters are met.

The K11MA7-P04LJG0-6560 substitute part demonstrates a higher current rating of 10A compared to the 8A rating of the primary part. Applications requiring the full 8A current capacity of the primary part will operate within the substitute's rated capability.

The primary part PRA.M0.4GL.LC65A maintains a higher maximum operating temperature of 150°C versus the substitute's 120°C maximum. Applications requiring operation above 120°C must utilize the primary part.

Both connectors share identical mechanical interfaces, termination methods, and environmental protection ratings, supporting direct substitution in applications operating within the overlapping parameter envelope of -50°C to 120°C and up to 8A current.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P04LJG0-6560 be used as a direct replacement for PRA.M0.4GL.LC65A?

A: Yes, for applications operating within -50°C to 120°C temperature range and requiring up to 8A current. Both connectors share identical 4-position configuration, solder cup termination, push-pull detent lock fastening, and IP50 ingress protection. Mechanical and electrical interfaces are equivalent.

Q: What is the primary difference between these two connector models?

A: The main differences are operating temperature range (PRA.M0.4GL.LC65A: -50°C to 150°C; K11MA7-P04LJG0-6560: -50°C to 120°C) and current rating (PRA.M0.4GL.LC65A: 8A; K11MA7-P04LJG0-6560: 10A). The substitute part supports higher current but lower maximum temperature.

Q: Are both parts RoHS compliant?

A: Yes, both PRA.M0.4GL.LC65A and K11MA7-P04LJG0-6560 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What cable opening diameter do these connectors accommodate?

A: Both connectors accept cable diameters within the range of 0.209" to 0.256" (5.30mm to 6.50mm).

Q: Can these connectors be used in medical applications?

A: Both connectors list medical applications in their approved use categories. Compliance with specific medical device standards and regulations must be verified based on end-use requirements.
