Engineering Selection Recommendations

Both parts maintain active production status and full ROHS3 compliance. The PRA.M0.4GL.LC52A remains the primary specification for designs requiring the -50°C ~ 150°C operating temperature range. The K11MA7-P04LJG0-5260 serves as a qualified substitute for applications operating within -50°C ~ 120°C, with the additional benefit of a 10A current rating versus the 8A rating of the primary part. Selection between these parts should be based on specific application temperature requirements and current load specifications. Both connectors are suitable for industrial, medical, and testing equipment applications with identical mechanical and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the K11MA7-P04LJG0-5260 be used as a direct replacement for the PRA.M0.4GL.LC52A?

A: The K11MA7-P04LJG0-5260 is mechanically and electrically compatible for applications operating within -50°C ~ 120°C. Applications requiring operation above 120°C must use the PRA.M0.4GL.LC52A, which is rated to 150°C.

Q: What are the key compatibility criteria for these connectors?

A: Compatibility is determined by: 4-position configuration, female socket receptacle type, solder cup termination, push-pull detent lock fastening, identical cable opening tolerances, and matching shell material (PSU) with gold contact finish.

Q: Are there differences in current handling capacity?

A: The PRA.M0.4GL.LC52A is rated for 8A, while the K11MA7-P04LJG0-5260 is rated for 10A. Existing designs specified for 8A operation are compatible with the higher-rated substitute.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference between shell size designations M04 and 1?

A: These are manufacturer-specific size designations for equivalent 4-position circular connector shells. Both support identical mechanical interfaces and cable opening tolerances.

Q: Are there packaging differences between these parts?

A: The PRA.M0.4GL.LC52A is supplied in standard packaging, while the K11MA7-P04LJG0-5260 is supplied in bulk packaging. This does not affect connector functionality or compatibility.
