Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M0.2GL.LC39G is determined by strict alignment of the following critical parameters:

Connector type: Receptacle with female sockets
Position count: 2 positions
Termination method: Solder cup
Fastening mechanism: Push-pull with detent lock
Contact finish: Gold plating
Shell material: Polysulfone (PSU)
Mounting configuration: Free hanging (in-line)
Ingress protection rating: IP50
Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)

Engineering Selection Recommendations

Both the PRG.M0.2GL.LC39G and K11M07-P02LPH0-3970 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications. The substitute part carries a higher current rating (14A) and supports a narrower maximum operating temperature range (120°C vs. 150°C). Selection between these parts should be based on application-specific thermal and current requirements. Both parts maintain identical mechanical and electrical interface specifications, enabling direct substitution in designs where the operating temperature does not exceed 120°C and current demand does not exceed 10A.

Frequently Asked Questions (FAQ)

Q: Can K11M07-P02LPH0-3970 be used as a direct replacement for PRG.M0.2GL.LC39G?

A: Yes, provided the application operates within the temperature range of -50°C to 120°C and current requirements do not exceed 10A. Both connectors share identical mechanical interfaces, fastening mechanisms, and electrical contact specifications.

Q: What are the key differences between these two parts?

A: The primary differences are the maximum operating temperature (150°C for LEMO vs. 120°C for ODU) and current rating (10A for LEMO vs. 14A for ODU). The ODU part supports higher current capacity but operates within a narrower thermal envelope.

Q: Are both parts suitable for medical applications?

A: Yes. Both the PRG.M0.2GL.LC39G and K11M07-P02LPH0-3970 are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status.

Q: What is the cable opening specification, and does it differ between parts?

A: Both parts support identical cable opening ranges of 0.106" to 0.154" (2.70mm to 3.90mm), ensuring compatibility with the same cable assemblies.

Q: Are these connectors shielded?

A: No. Both the PRG.M0.2GL.LC39G and K11M07-P02LPH0-3970 are unshielded connectors. If electromagnetic shielding is required, alternative connector designs must be evaluated.

Q: What termination method do these connectors use?

A: Both connectors use solder cup termination, requiring direct soldering to PCB pads or wire leads. No crimping or other termination methods are applicable.

Q: Do these parts require special handling or storage conditions?

A: Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
