Key Parameters

Substitute Part Grouping Explanation

The K11MA7-P04LJG0-6550 (ODU MEDI-SNAP®) qualifies as a substitute based on the following critical parameters:

• Connector Configuration: Both parts are 4-position circular connector receptacles with female sockets
• Termination Method: Both utilize solder cup termination for identical PCB integration
• Fastening Mechanism: Both employ push-pull detent lock fastening
• Shell Material: Both feature Polysulfone (PSU) construction
• Contact Finish: Both specify gold mating surface finish
• Ingress Protection: Both meet IP50 dust protection rating
• Cable Opening Compatibility: Both accommodate 0.209" ~ 0.256" (5.30mm ~ 6.50mm) cable diameters
• Regulatory Compliance: Both are ROHS3 compliant with MSL 1 rating

Substitution is valid within the specified parameter constraints. Differences in current rating (10A vs 8A) and maximum operating temperature (-50°C ~ 120°C vs -50°C ~ 150°C) represent performance variations that do not preclude substitution when application requirements fall within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC65V and K11MA7-P04LJG0-6550 maintain active production status and full ROHS3 compliance. Selection between these parts should be based on application-specific requirements:

• Temperature Environment: Applications requiring sustained operation above 120°C necessitate the PRA.M0.4GL.LC65V due to its extended operating range to 150°C
• Current Capacity: Applications demanding continuous current above 8A benefit from the K11MA7-P04LJG0-6550's 10A rating
• Standard Operating Conditions: For applications within -50°C ~ 120°C and ≤8A, either part satisfies functional requirements
• Supply Chain Considerations: Current inventory levels (1,057 units for LEMO; 751 units for ODU) may influence procurement decisions

Both parts carry identical regulatory certifications (ROHS3, REACH Unaffected, EAR99) and moisture sensitivity ratings, ensuring equivalent compliance posture across regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the K11MA7-P04LJG0-6550 be used as a direct replacement for the PRA.M0.4GL.LC65V?

A: Yes, within application parameter constraints. Both connectors share identical mechanical interfaces (4-position, solder cup termination, push-pull detent lock), shell materials, and contact finishes. Verify that your application operates within the substitute's temperature range (-50°C ~ 120°C) and current requirements (≤10A).

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (PRA.M0.4GL.LC65V extends to 150°C versus K11MA7-P04LJG0-6550 at 120°C) and current rating (8A versus 10A respectively). Both differences represent performance enhancements in the substitute part for standard industrial applications.

Q: Are both connectors suitable for medical applications?

A: Yes. Both parts list medical applications in their specifications and maintain ROHS3 compliance. The ODU MEDI-SNAP® series designation indicates specific medical market positioning for the K11MA7-P04LJG0-6550.

Q: What is the cable opening specification, and does it affect substitution?

A: Both connectors accommodate identical cable opening ranges of 0.209" ~ 0.256" (5.30mm ~ 6.50mm). This parameter is matched across both parts, ensuring equivalent backshell and cable strain relief compatibility.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage or handling. Standard component storage practices apply.

Q: What is the contact material composition for each connector?

A: The PRA.M0.4GL.LC65V contact material specification is not provided in the technical data. The K11MA7-P04LJG0-6550 specifies brass contact material with gold mating finish. Both employ gold contact finish for mating surfaces.
