Key Parameters

Substitute Part Grouping Explanation

The substitute part K21M07-P04LJG0-657S from ODU is classified as an equivalent based on the following matching parameters:

• Connector Configuration: Both parts are 4-position circular connector receptacles with female sockets
• Termination Method: Both use solder cup termination
• Fastening Mechanism: Both employ push-pull detent lock fastening
• Shell Material: Both utilize Polysulfone (PSU) construction
• Contact Finish: Both feature gold-plated mating surfaces
• Cable Opening Specification: Both accommodate 0.209" ~ 0.256" (5.30mm ~ 6.50mm) cable diameters
• Ingress Protection: Both provide IP50 dust protection rating
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Mounting Type: Both are configured for free hanging in-line mounting

The substitute part is suitable for applications where LEMO PRG.M0 series connectors can be replaced with ODU MEDI-SNAP® equivalents, subject to design validation of the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.4GL.LC65Z and K21M07-P04LJG0-657S are active production parts with full regulatory compliance. Selection between these parts should be based on the following factors:

LEMO PRG.M0.4GL.LC65Z is appropriate when:

• Operating temperature range up to 150°C is required
• Current rating of 8A meets application specifications
• LEMO connector ecosystem integration is preferred

ODU K21M07-P04LJG0-657S is appropriate when:

• Current rating of 10A is required
• Operating temperature range up to 120°C is acceptable
• ODU MEDI-SNAP® series integration is preferred
• Strain relief feature is beneficial for the application

Both parts maintain identical compliance certifications (ROHS3, REACH unaffected) and share equivalent mechanical and electrical interfaces for the 4-position solder cup configuration.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P04LJG0-657S directly replace PRG.M0.4GL.LC65Z in all applications?

A: Direct replacement is possible when the application operating temperature does not exceed 120°C and the 10A current rating of the ODU part is acceptable. The PRG.M0.4GL.LC65Z supports higher temperature operation (up to 150°C), which may be required in specific automotive or industrial applications.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share identical 4-position configuration, solder cup termination, push-pull detent lock fastening, cable opening specifications (5.30mm ~ 6.50mm), and IP50 ingress protection. These parameters ensure mechanical and electrical compatibility in equivalent applications.

Q: Are there differences in contact material between these parts?

A: The PRG.M0.4GL.LC65Z does not specify contact material in the provided data. The K21M07-P04LJG0-657S uses brass contacts with gold plating. Both parts feature gold-plated mating surfaces.

Q: What is the significance of the strain relief feature on the ODU part?

A: The K21M07-P04LJG0-657S includes strain relief as an additional mechanical feature. This provides enhanced cable protection at the connector interface, which may be beneficial in applications subject to vibration or mechanical stress.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the PRG.M0.4GL.LC65Z and K21M07-P04LJG0-657S are ROHS3 compliant, REACH unaffected, and classified under the same HTSUS code (8536.69.4020) with EAR99 ECCN designation.

Q: What packaging options are available?

A: The PRG.M0.4GL.LC65Z is available in standard packaging. The K21M07-P04LJG0-657S is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
