Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M0.4GL.LC65GZ is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets, 4-position circular connector
• Termination Method: Solder cup termination for direct PCB or cable integration
• Fastening Mechanism: Push-pull detent lock engagement
• Contact Interface: Gold-plated mating surface for reliable electrical connection
• Shell Material: Polysulfone (PSU) construction
• Mechanical Compatibility: Cable opening range 0.209" ~ 0.256" (5.30mm ~ 6.50mm)
• Environmental Rating: IP50 dust protection and operating temperature range
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part K21M07-P04LJG0-657S from ODU meets these core substitution criteria while maintaining functional equivalence for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.4GL.LC65GZ and K21M07-P04LJG0-657S maintain active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on the following provided specifications:

PRG.M0.4GL.LC65GZ (LEMO) is suitable for applications requiring the full operating temperature range of -50°C to 150°C. This part supports an 8A current rating and is available with 815 units in stock.

K21M07-P04LJG0-657S (ODU) is suitable for applications operating within -50°C to 120°C. This part supports a higher 10A current rating and includes integrated strain relief features. Inventory availability is 715 units.

Both connectors share identical mechanical interfaces, termination methods, and environmental protection ratings. The choice between them depends on specific application temperature requirements and current demands within the stated operating ranges.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P04LJG0-657S replace PRG.M0.4GL.LC65GZ in all applications?

A: Substitution is valid for applications operating within the -50°C to 120°C temperature range. If your application requires operation above 120°C, the PRG.M0.4GL.LC65GZ is the appropriate choice due to its extended upper temperature limit of 150°C.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical cable opening specifications (0.209" ~ 0.256" or 5.30mm ~ 6.50mm), 4-position configuration, push-pull detent lock fastening, and solder cup termination. Mechanical interchangeability is confirmed for these parameters.

Q: Are there differences in current handling capacity?

A: The PRG.M0.4GL.LC65GZ is rated for 8A, while the K21M07-P04LJG0-657S is rated for 10A. For applications requiring currents above 8A but within 10A, the ODU substitute provides additional capacity.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both connectors are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory compliance is equivalent.

Q: What is the difference in packaging?

A: The PRG.M0.4GL.LC65GZ is supplied in standard packaging, while the K21M07-P04LJG0-657S is supplied in bulk packaging. This affects handling and storage procedures but does not impact electrical or mechanical performance.

Q: Are there any feature differences?

A: The K21M07-P04LJG0-657S includes integrated strain relief in addition to the backshell feature present on both connectors. The PRG.M0.4GL.LC65GZ features backshell only. This additional strain relief on the substitute part provides enhanced mechanical protection for the cable assembly.
