Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.5GL.LC65G is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Receptacle, female sockets, 5-position configuration
• Termination Method: Solder cup for PCB integration
• Fastening Mechanism: Push-pull detent lock for secure mating
• Shell & Insert Materials: Polysulfone (PSU) shell with PEEK insert for mechanical and thermal stability
• Contact Finish: Gold-plated mating surfaces for corrosion resistance and electrical performance
• Ingress Protection: IP50 dust protection rating
• Cable Opening Dimensions: 0.209" ~ 0.256" (5.30mm ~ 6.50mm) for consistent backshell compatibility
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The substitute part K11MA7-P05LJG0-6570 (ODU MEDI-SNAP®) meets these core substitution criteria, enabling direct functional replacement in compatible applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.5GL.LC65G and K11MA7-P05LJG0-6570 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, supporting long-term supply chain stability. The ODU MEDI-SNAP® substitute provides a current rating of 7.5A, exceeding the LEMO part's 7A specification, making it suitable for applications with equivalent or lower current demands.

The primary consideration is operating temperature range. The LEMO part supports -50°C to 150°C, while the ODU substitute operates within -50°C to 120°C. Applications requiring sustained operation above 120°C must use the original PRA.M0.5GL.LC65G. For applications within the -50°C to 120°C envelope, the ODU part provides functional equivalence with higher current capacity.

Both connectors maintain identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring direct substitution in PCB solder cup applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P05LJG0-6570 be used as a direct replacement for PRA.M0.5GL.LC65G?

A: Yes, for applications operating within -50°C to 120°C. Both parts share identical connector type, position count, termination method, fastening mechanism, shell material, contact finish, and ingress protection. The ODU part's 7.5A current rating exceeds the LEMO specification, supporting equivalent or lower current applications. Applications requiring operation above 120°C must use the original LEMO part.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is based on matching connector type (receptacle, female sockets), position count (5), termination method (solder cup), fastening type (push-pull detent lock), shell and insert materials (PSU/PEEK), contact finish (gold), ingress protection (IP50), and cable opening dimensions (0.209" ~ 0.256"). Deviations in any of these parameters disqualify a part from substitution.

Q: Are there differences in packaging between these parts?

A: The LEMO part is supplied in standard packaging, while the ODU substitute is supplied in bulk packaging. This distinction affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both PRA.M0.5GL.LC65G and K11MA7-P05LJG0-6570 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8536.69.4020.

Q: What applications are supported by these connectors?

A: Both parts are suitable for automotive, industrial, medical, and testing equipment applications. The ODU part additionally lists military applications within its specification.
