Substitute Part Grouping Explanation

Substitute parts for the PRG.M0.5GL.LC39Z are identified based on strict equivalence across the following critical parameters:

• Connector Configuration: Receptacle with female sockets
• Position Count: 5 positions
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull detent lock
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Ingress Protection: IP50 dust protection rating
• Cable Opening Range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part K21M07-P05LJG0-397S from ODU meets these core substitution criteria. Variations in shell size designation (M05 versus 1), operating temperature range, and current rating are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.5GL.LC39Z and K21M07-P05LJG0-397S maintain active product status and ROHS3 compliance, qualifying them for use in regulated applications. The LEMO connector supports a higher maximum operating temperature of 150°C compared to the ODU substitute at 120°C. The ODU part provides a marginally higher current rating of 7.5A versus 7A and includes integrated strain relief in addition to the backshell.

Selection between these parts depends on application-specific temperature requirements. For applications operating above 120°C, the LEMO PRG.M0.5GL.LC39Z is the appropriate choice. For applications within the -50°C to 120°C range, the ODU K21M07-P05LJG0-397S provides equivalent functionality with additional strain relief features.

Frequently Asked Questions (FAQ)

Q: Can the K21M07-P05LJG0-397S replace the PRG.M0.5GL.LC39Z in all applications?

A: The ODU substitute is compatible for applications operating within -50°C to 120°C. Applications requiring operation above 120°C must use the LEMO part, which is rated to 150°C.

Q: What is the significance of the shell size designation difference (M05 versus 1)?

A: Both designations refer to equivalent shell sizes within their respective manufacturer standards. The physical dimensions and mating interfaces are compatible.

Q: Are both connectors suitable for solder cup termination?

A: Yes. Both the LEMO PRG.M0.5GL.LC39Z and ODU K21M07-P05LJG0-397S feature solder cup termination, allowing direct soldering to PCB traces or wire leads.

Q: What is the difference in current rating between these parts?

A: The LEMO part is rated for 7A, while the ODU substitute is rated for 7.5A. Both ratings are suitable for low-power signal and moderate-power applications. Design margins should account for the lower LEMO rating if current capacity is critical.

Q: Do both connectors provide the same ingress protection?

A: Yes. Both parts provide IP50 dust protection, suitable for industrial and medical environments where dust ingress prevention is required.

Q: What additional features does the ODU connector provide?

A: The ODU K21M07-P05LJG0-397S includes integrated strain relief in addition to the backshell, providing enhanced cable retention and mechanical durability compared to the LEMO part.
