Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.4GL.LC52A and K11M07-P04LJG0-5260 are active production parts with ROHS3 compliance and equivalent mechanical and electrical characteristics for 4-position circular connector receptacle applications.

The PRG.M0.4GL.LC52A (LEMO) provides an extended operating temperature range of -50°C to 150°C, making it suitable for applications requiring higher temperature performance.

The K11M07-P04LJG0-5260 (ODU MEDI-SNAP®) offers a higher current rating of 10A compared to the 8A rating of the main part, with an operating temperature range of -50°C to 120°C. This substitute is suitable for applications within the specified temperature range that may benefit from increased current capacity.

Selection between these parts should be based on specific application requirements regarding operating temperature limits and current demands, with both parts meeting the same compliance and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can K11M07-P04LJG0-5260 be used as a direct replacement for PRG.M0.4GL.LC52A?

A: Yes, for applications operating within -50°C to 120°C and requiring up to 10A current. Both connectors share identical mechanical dimensions, termination method, fastening type, and shell material. Verify your application's temperature and current requirements before substitution.

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

A: M04 and 1 represent different nomenclature systems used by LEMO and ODU respectively. Both designations refer to equivalent mechanical dimensions for 4-position circular connectors in this product category.

Q: Are there any compatibility concerns with solder cup termination between these parts?

A: No. Both parts use identical solder cup termination and cable opening specifications (0.157" ~ 0.205" / 4.00mm ~ 5.20mm), ensuring mechanical and electrical compatibility in PCB assembly and wiring applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both PRG.M0.4GL.LC52A and K11M07-P04LJG0-5260 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the primary consideration when choosing between these two connectors?

A: Operating temperature range and current capacity are the primary differentiators. The LEMO part supports -50°C to 150°C at 8A, while the ODU part supports -50°C to 120°C at 10A. Select based on your application's thermal and electrical requirements.
