Parameter Comparison

Engineering Selection Recommendations

Both the PRG.M0.8GL.LC39G and K11M07-P08LFG0-3970 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in industrial, medical, and automotive environments.

Selection between these parts should be based on application-specific requirements:

PRG.M0.8GL.LC39G (LEMO) is the primary choice when applications require the full 5A current rating and extended operating temperature range to 150°C.

K11M07-P08LFG0-3970 (ODU MEDI-SNAP®) is suitable for applications with current requirements up to 3.85A and operating temperatures within the -50°C to 120°C range. This substitute maintains mechanical and electrical compatibility across all critical connector parameters.

Both parts share identical mechanical interfaces, contact finishes, and ingress protection ratings, ensuring physical and functional interchangeability within their respective electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can K11M07-P08LFG0-3970 be used as a direct replacement for PRG.M0.8GL.LC39G?

A: The K11M07-P08LFG0-3970 is mechanically and functionally compatible with the PRG.M0.8GL.LC39G. However, the substitute part has a lower current rating (3.85A vs. 5A) and reduced maximum operating temperature (120°C vs. 150°C). Substitution is valid only when application requirements fall within these lower limits.

Q: What are the critical parameters for substitution between these connectors?

A: The critical parameters are: 8-position configuration, receptacle female socket type, solder cup termination, push-pull detent lock fastening, gold contact finish, polysulfone shell material, and IP50 ingress protection. Both parts meet these specifications identically.

Q: Are there packaging differences between these parts?

A: The PRG.M0.8GL.LC39G is supplied in standard packaging, while the K11M07-P08LFG0-3970 is supplied in bulk packaging. This difference does not affect connector performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PRG.M0.8GL.LC39G and K11M07-P08LFG0-3970 are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level), making them suitable for the same regulated applications.

Q: What is the cable opening specification for both connectors?

A: Both connectors accommodate cable openings of 0.106" to 0.154" (2.70mm to 3.90mm), ensuring identical cable compatibility.
