Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRA.M1.4GL.LC65G is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets
• Position Count: 14 positions
• Termination Method: Solder cup
• Fastening Mechanism: Push-Pull with detent lock
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Mounting Style: Free hanging, in-line orientation
• Ingress Protection: IP50 dust protection
• Cable Opening Range: 0.209" ~ 0.256" (5.30mm ~ 6.50mm)
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part K11MA7-P14LCC0-6570 (ODU MEDI-SNAP®) meets all critical substitution criteria. Variations in current rating (2.5A vs. 2A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) are noted but do not preclude substitution when application requirements fall within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PRA.M1.4GL.LC65G and K11MA7-P14LCC0-6570 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

Selection between these parts should be based on:

1. Current Requirements: The ODU substitute provides 2.5A rating versus the LEMO part's 2A rating. Applications requiring currents between 2A and 2.5A may benefit from the higher-rated substitute.

2. Temperature Operating Range: The LEMO part supports operation to 150°C, while the ODU substitute operates to 120°C maximum. Applications requiring sustained operation above 120°C require the LEMO part.

3. Inventory Availability: LEMO PRA.M1.4GL.LC65G has 735 units in stock; ODU K11MA7-P14LCC0-6570 has 1004 units in stock.

4. Compliance Certifications: Both parts meet ROHS3 and REACH requirements for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can K11MA7-P14LCC0-6570 directly replace PRA.M1.4GL.LC65G in all applications?

A: Direct replacement is possible when application current requirements do not exceed 2.5A and maximum operating temperature does not exceed 120°C. Both connectors share identical mechanical interfaces, pin counts, termination methods, and fastening mechanisms.

Q: What is the difference between shell size designations M14 and 1?

A: Both designations refer to equivalent shell sizes within their respective manufacturer standards. The connectors are mechanically compatible for mating purposes.

Q: Are there any compatibility issues with existing mating plugs?

A: No. Both receptacles feature identical push-pull detent lock fastening, orientation (A), and mechanical dimensions. Existing mating plugs designed for the LEMO part will mate with the ODU substitute.

Q: How do the contact materials differ between these parts?

A: The LEMO part does not specify contact material in the provided data. The ODU substitute uses brass contacts with gold plating. Both feature gold-plated mating surfaces.

Q: What packaging formats are available?

A: The LEMO PRA.M1.4GL.LC65G is supplied in standard packaging. The ODU K11MA7-P14LCC0-6570 is supplied in bulk packaging.

Q: Are both parts suitable for medical device applications?

A: Yes. Both parts are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status required for medical device manufacturing.
