Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P14MCC0-3980 (ODU MEDI-SNAP®) is identified as an equivalent based on the following critical parameters that determine substitution compatibility:

Matching Parameters:

• 14-position connector configuration
• Male pin plug connector type
• Solder cup termination
• Push-Pull fastening mechanism
• Gold contact finish (mating surface)
• Polysulfone shell material
• PEEK insert material
• IP50 ingress protection rating
• Free hanging in-line mounting
• Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• RoHS3 compliance
• MSL 1 rating

Allowable Variations:

• Shell size insert designation differs (M14 vs. 1) due to manufacturer-specific nomenclature
• Current rating: 2A (PAA.M1.4GL.AC39N) vs. 2.5A (S11MA7-P14MCC0-3980) - substitute supports higher current
• Operating temperature upper limit: 150°C (PAA.M1.4GL.AC39N) vs. 120°C (S11MA7-P14MCC0-3980) - main part supports higher temperature
• Fastening type: PAA.M1.4GL.AC39N includes detent lock; S11MA7-P14MCC0-3980 specifies push-pull only
• Contact material: Not specified for PAA.M1.4GL.AC39N; S11MA7-P14MCC0-3980 specifies brass

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.4GL.AC39N and S11MA7-P14MCC0-3980 are active production parts with full RoHS3 compliance and MSL 1 ratings, making them suitable for equivalent selection in applications where the specified parameters align.

PAA.M1.4GL.AC39N (LEMO) is the primary choice when:

• Operating temperature requirements exceed 120°C (up to 150°C maximum)
• Detent lock fastening mechanism is required for secure mating

S11MA7-P14MCC0-3980 (ODU MEDI-SNAP®) is suitable as a substitute when:

• Current requirements up to 2.5A are needed (exceeds 2A rating of primary part)
• Operating temperature range of -50°C to 120°C is acceptable
• Push-pull fastening without detent lock is compatible with application design
• ODU MEDI-SNAP® series integration is preferred for system architecture

Both parts share identical 14-position solder cup configuration, gold contact finish, polysulfone shell construction, PEEK inserts, and cable opening specifications, ensuring mechanical and electrical compatibility within the stated parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P14MCC0-3980 be used as a direct replacement for PAA.M1.4GL.AC39N?

A: Substitution is possible when application requirements permit the parameter variations listed in the comparison table. The substitute supports higher current (2.5A vs. 2A) but operates at a lower maximum temperature (120°C vs. 150°C). The fastening mechanism differs (push-pull only vs. push-pull with detent lock). Verify that your application does not require the detent lock feature or sustained operation above 120°C.

Q: What are the critical matching parameters for this connector substitution?

A: The 14-position configuration, male pin plug type, solder cup termination, gold contact finish, polysulfone shell, PEEK insert material, and IP50 ingress protection are the primary parameters that establish substitution compatibility. Cable opening dimensions and mounting type must also align.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, carry MSL 1 ratings, and are active production items. No compliance or certification barriers exist for substitution.

Q: What is the significance of the shell size designation difference (M14 vs. 1)?

A: The shell size designations reflect manufacturer-specific nomenclature systems. Both parts are 14-position connectors with compatible mechanical interfaces. The different designations do not indicate incompatibility.

Q: Does the higher current rating of the substitute part affect compatibility?

A: The S11MA7-P14MCC0-3980 is rated for 2.5A compared to the 2A rating of the PAA.M1.4GL.AC39N. A higher current rating does not create incompatibility; it indicates the substitute can handle equal or greater current loads. Applications requiring only 2A operation are fully compatible with the substitute.

Q: What should be considered regarding the operating temperature difference?

A: The PAA.M1.4GL.AC39N operates to 150°C while the S11MA7-P14MCC0-3980 operates to 120°C. If your application requires sustained operation above 120°C, the LEMO part is required. For applications within the -50°C to 120°C range, both parts are equivalent.
