Substitute Part Grouping Explanation

Substitute parts for the PRG.M0.8GL.LC39GZ 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
• Ingress Protection: IP50 dust protection
• Cable Opening Dimensions: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part K21M07-P08LFG0-397S (ODU MEDI-SNAP®) meets these core substitution criteria. Variations in current rating, maximum operating temperature, and additional features (strain relief) are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.8GL.LC39GZ 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.LC39GZ supports a maximum current rating of 5A and operating temperature range of -50°C to 150°C. The K21M07-P08LFG0-397S operates at 3.85A maximum current and -50°C to 120°C, with the addition of strain relief features. Selection between these parts depends on application-specific current and temperature requirements. The ODU substitute includes integrated strain relief, which may provide additional mechanical protection in cable-intensive installations.

Both connectors share identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring physical and electrical compatibility in applications where the specified current and temperature parameters are within acceptable limits.

Frequently Asked Questions (FAQ)

Q: Can the K21M07-P08LFG0-397S replace the PRG.M0.8GL.LC39GZ in all applications?

A: Substitution is valid where application current requirements do not exceed 3.85A and maximum operating temperature does not exceed 120°C. Both connectors share identical mechanical interfaces, fastening mechanisms, and contact configurations. Applications requiring the full 5A rating or extended temperature operation to 150°C must use the PRG.M0.8GL.LC39GZ.

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

A: Both connectors feature 8-position female socket receptacles with solder cup termination, push-pull detent lock fastening, identical cable opening dimensions (0.106" ~ 0.154"), polysulfone shells with gold-plated contacts, and IP50 ingress protection. These parameters ensure mechanical and electrical interchangeability within the specified electrical and thermal operating ranges.

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

A: The PRG.M0.8GL.LC39GZ contact material is not specified in the provided data. The K21M07-P08LFG0-397S uses brass contacts with gold mating finish. Both employ identical insert materials (PEEK) and backshell materials (PSU).

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

A: The K21M07-P08LFG0-397S includes integrated strain relief in addition to the backshell. This feature provides additional mechanical support at the cable entry point, reducing stress on solder connections during cable flexing or vibration. The PRG.M0.8GL.LC39GZ backshell does not include this feature.

Q: Are both connectors suitable for medical applications?

A: Both connectors are listed for medical applications. Both are ROHS3 compliant and have MSL rating of 1 (unlimited moisture sensitivity). Application-specific validation is required based on medical device classification and intended use.

Q: What packaging options are available?

A: The PRG.M0.8GL.LC39GZ is available in standard packaging. The K21M07-P08LFG0-397S is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.
