Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.4GL.LC52Z is determined by the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets
• Position Count: 4 positions
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull detent lock
• Contact Finish: Gold plating for mating surfaces
• Shell Material: Polysulfone (PSU)
• Insert Material: Polyetheretherketone (PEEK)
• Ingress Protection: IP50 dust protection
• Compliance: ROHS3 compliant

The identified substitute part K21MA7-P04LJG0-527S from ODU maintains compatibility across these core parameters, enabling direct functional substitution in applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC52Z and K21MA7-P04LJG0-527S maintain active product status and full ROHS3 compliance with REACH unaffected classification. Selection between these parts should be based on the following considerations:

PRA.M0.4GL.LC52Z (LEMO) is suitable for applications requiring the full operating temperature range of -50°C to 150°C and where the 8A current rating meets system requirements.

K21MA7-P04LJG0-527S (ODU) provides a higher current rating of 10A and includes integrated strain relief features. The operating temperature range extends to -120°C minimum but is limited to 120°C maximum. This part is appropriate for applications where the reduced upper temperature limit is acceptable and higher current capacity is beneficial.

Both connectors are certified for industrial, medical, and testing equipment applications with equivalent mechanical and electrical performance across their respective operating ranges.

Frequently Asked Questions (FAQ)

Q: Can K21MA7-P04LJG0-527S directly replace PRA.M0.4GL.LC52Z in all applications?

A: Direct substitution is possible for applications where the operating temperature does not exceed 120°C. The PRA.M0.4GL.LC52Z supports temperatures up to 150°C, while the ODU substitute is limited to 120°C maximum. Verify application temperature requirements before substitution.

Q: What are the differences in current rating between these parts?

A: The PRA.M0.4GL.LC52Z is rated for 8A, while the K21MA7-P04LJG0-527S is rated for 10A. Both ratings are suitable for standard industrial and medical applications. Select based on actual circuit current requirements.

Q: Are both parts compliant with regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements.

Q: What is the difference in shell size designation?

A: The PRA.M0.4GL.LC52Z uses shell size M04, while the K21MA7-P04LJG0-527S uses shell size 1. Both designations refer to equivalent 4-position connector configurations within their respective manufacturer standards.

Q: Does the ODU part include additional features?

A: The K21MA7-P04LJG0-527S includes integrated strain relief in addition to the backshell feature present on both parts. This provides enhanced cable protection and mechanical durability in applications subject to cable flexing or vibration.
