Substitute Part Grouping Explanation

Substitute parts for the PRG.M0.8GL.LC39Z are identified based on strict alignment of the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets
• Position Count: 8 positions
• Termination Method: Solder cup
• Fastening Mechanism: Push-pull detent lock
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Mounting Style: Free hanging (in-line)
• Ingress Protection: IP50 dust protection
• Cable Opening Range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part K21M07-P08LFG0-397S from ODU meets these core substitution criteria. Variations in operating temperature range, current rating, and series designation do not preclude substitution where application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.8GL.LC39Z and K21M07-P08LFG0-397S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications.

The PRG.M0.8GL.LC39Z supports a maximum current rating of 5A and operating temperature range of -50°C to 150°C. The ODU substitute K21M07-P08LFG0-397S operates at 3.85A maximum current and -50°C to 120°C. Selection between these parts depends on application-specific current and temperature requirements. Where applications require the full 5A rating or sustained operation above 120°C, the LEMO part is the appropriate choice. Where application requirements fall within 3.85A and 120°C maximum conditions, the ODU part provides a functionally equivalent alternative.

Both connectors share identical mechanical interfaces, termination methods, and protective ratings, ensuring physical and electrical compatibility in applications where performance specifications align.

Frequently Asked Questions (FAQ)

Q: Can the K21M07-P08LFG0-397S replace the PRG.M0.8GL.LC39Z in all applications?

A: Substitution is valid only where application current requirements do not exceed 3.85A and operating temperature remains within -50°C to 120°C. The LEMO part supports higher current (5A) and extended temperature range (-50°C to 150°C). Verify application specifications before substitution.

Q: Are the physical dimensions and mating interfaces identical?

A: Yes. Both connectors share the same 8-position configuration, M08 shell size, cable opening range (0.106" ~ 0.154"), push-pull detent lock fastening, and solder cup termination. Physical interchangeability is confirmed for mechanical integration.

Q: What is the difference in contact material between these parts?

A: The LEMO PRG.M0.8GL.LC39Z does not specify contact material in the provided data. The ODU K21M07-P08LFG0-397S uses brass contacts with gold plating. Both feature gold contact finish on mating surfaces, ensuring equivalent electrical performance for signal transmission.

Q: Are both parts suitable for medical device applications?

A: Yes. Both the PRG.M0.8GL.LC39Z and K21M07-P08LFG0-397S are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for medical equipment.

Q: What is the difference in packaging?

A: The LEMO part is supplied in standard packaging. The ODU substitute is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: How do the operating temperature ranges affect substitution decisions?

A: The LEMO part operates from -50°C to 150°C, while the ODU part operates from -50°C to 120°C. Applications requiring sustained operation above 120°C must use the LEMO part. Applications within the -50°C to 120°C range can use either part.
