Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M0.4GL.LC65N is determined by strict alignment of the following critical parameters:

Connector type and gender (Receptacle, Female Sockets)
Number of positions (4)
Termination method (Solder Cup)
Fastening mechanism (Push-Pull, Detent Lock)
Contact finish (Gold plating)
Shell material (Polysulfone)
Ingress protection rating (IP50)
Mounting configuration (Free Hanging, In-Line)
Insert material (Polyetheretherketone PEEK)
Backshell presence and material

The substitute part K11MA7-P04LJG0-6580 (ODU MEDI-SNAP® series) meets all critical substitution criteria. Both parts share identical connector architecture, termination approach, and environmental sealing specifications. Differences in current rating (10A vs. 8A) and maximum operating temperature (120°C vs. 150°C) represent performance enhancements in the substitute part, making it suitable for applications within the original part's operational envelope.

Engineering Selection Recommendations

Both the PRA.M0.4GL.LC65N and K11MA7-P04LJG0-6580 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications. Selection between these parts should be based on:

Supply availability and lead time requirements
Application-specific current demands (8A vs. 10A rating)
Temperature operating envelope constraints (150°C vs. 120°C maximum)
Inventory positioning and procurement cost considerations
Connector series standardization within system design

Both parts maintain identical mechanical and electrical interfaces, supporting direct substitution in solder cup termination applications. The ODU MEDI-SNAP® series substitute provides enhanced current capacity, making it suitable for applications requiring higher power delivery within the original thermal operating window.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P04LJG0-6580 be used as a direct replacement for PRA.M0.4GL.LC65N?

A: Yes. Both connectors share identical connector type, position count, termination method, fastening mechanism, contact finish, shell material, ingress protection rating, and mounting configuration. The substitute part is mechanically and electrically compatible for direct substitution in solder cup applications.

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

A: The primary differences are manufacturer (LEMO vs. ODU), connector series designation (1P vs. ODU MEDI-SNAP®), current rating (8A vs. 10A), and maximum operating temperature (150°C vs. 120°C). The substitute part offers higher current capacity and is suitable for applications operating within its 120°C maximum temperature specification.

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

A: No. Both parts use identical solder cup termination and cable opening specifications (0.209" ~ 0.256" / 5.30mm ~ 6.50mm), ensuring compatible PCB and cable assembly integration.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both PRA.M0.4GL.LC65N and K11MA7-P04LJG0-6580 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial, medical, and automotive applications.

Q: Which part should be selected for high-temperature applications?

A: The PRA.M0.4GL.LC65N supports operation up to 150°C, making it suitable for applications requiring extended temperature performance. The K11MA7-P04LJG0-6580 is rated to 120°C maximum and should be selected only for applications within this thermal envelope.

Q: Are there packaging differences between these connectors?

A: The PRA.M0.4GL.LC65N is supplied in standard packaging, while K11MA7-P04LJG0-6580 is supplied in bulk packaging. Both are available in active production with adequate inventory levels.
