Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M1.4GL.AC39GZ are identified based on strict equivalence of the following critical parameters:

• Connector Type & Configuration: Plug with male pins
• Position Count: 14 positions
• Termination Method: Solder cup
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Fastening Mechanism: Push-pull connection system
• Ingress Protection: IP50 dust protection rating
• Cable Opening Range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Mounting Style: Free hanging (in-line)
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part S21MA7-P14MCC0-397S from ODU meets these core substitution criteria while maintaining functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.4GL.AC39GZ and S21MA7-P14MCC0-397S are active production parts with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications.

The LEMO PAA.M1.4GL.AC39GZ provides an operating temperature range of -50°C to 150°C with a 2A current rating and detent lock fastening mechanism.

The ODU S21MA7-P14MCC0-397S operates within -50°C to 120°C with a 2.5A current rating and standard push-pull fastening. The ODU part includes strain relief features and is available in higher inventory (1123 units).

Selection between these parts should be based on specific application requirements regarding maximum operating temperature, current capacity, and fastening mechanism preference. Both parts maintain equivalent mechanical and electrical interfaces for the 14-position solder cup configuration.

Frequently Asked Questions (FAQ)

Q: Can the ODU S21MA7-P14MCC0-397S directly replace the LEMO PAA.M1.4GL.AC39GZ?

A: Direct mechanical and electrical replacement is possible for applications operating within the ODU part's temperature range (-50°C to 120°C) and current requirements (up to 2.5A). The 14-position solder cup interface, shell material, contact finish, and cable opening dimensions are identical. The fastening mechanism differs (detent lock versus standard push-pull), which may affect connector retention characteristics in specific mounting configurations.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by: 14-position count, solder cup termination, polysulfone shell material, gold contact finish, IP50 ingress protection, 0.106" to 0.154" cable opening range, and push-pull fastening system. Deviations in any of these parameters indicate incompatibility.

Q: Are there temperature or current limitations when using the substitute part?

A: The ODU substitute part operates to a maximum of 120°C, compared to 150°C for the LEMO original. Applications requiring sustained operation above 120°C must use the LEMO part. The ODU part supports 2.5A versus 2A for the LEMO part, providing additional current capacity margin.

Q: What packaging options are available?

A: The LEMO PAA.M1.4GL.AC39GZ is available in standard packaging. The ODU S21MA7-P14MCC0-397S is supplied in bulk packaging.

Q: Are both parts compliant with current regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial, medical, and automotive applications.
