Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M1.4GL.AC65Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug configuration with 14 positions
• Termination Method: Solder cup termination required
• Shell Material & Contact Finish: Polysulfone shell with gold-plated mating contacts
• Fastening Mechanism: Push-pull connection with detent lock capability
• Ingress Protection: IP50 dust protection rating
• Operating Temperature: Minimum -50°C to 150°C range
• Current Rating: Minimum 2A capacity
• Compliance: ROHS3 compliant, REACH unaffected

The identified substitute part S21MA7-P14MCC0-657S from ODU meets these core substitution criteria while maintaining functional compatibility for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

The S21MA7-P14MCC0-657S from ODU is a qualified substitute for the PAA.M1.4GL.AC65Z based on matching core electrical and mechanical specifications. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial, medical, and automotive applications.

Selection between these parts should account for the following:

• Temperature Limitation: The ODU substitute operates to a maximum of 120°C, compared to 150°C for the LEMO part. Applications requiring sustained operation above 120°C must use the PAA.M1.4GL.AC65Z.
• Current Capacity: The ODU part provides 2.5A rating versus 2A for the LEMO part, offering additional current margin in applications operating at or near the 2A specification.
• Availability: Both parts are active production items with confirmed inventory. Selection may be based on lead time, pricing, or supply chain considerations.
• Series Compatibility: The LEMO part belongs to the 2P series, while the ODU part is part of the ODU MEDI-SNAP® series. Mechanical interface compatibility with mating receptacles must be verified for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the S21MA7-P14MCC0-657S directly replace the PAA.M1.4GL.AC65Z in all applications?

A: The ODU part is mechanically and electrically compatible for most applications. However, applications requiring continuous operation above 120°C must use the LEMO part, as the ODU substitute is rated to 120°C maximum.

Q: What are the key differences between these two 14-position connectors?

A: The primary differences are operating temperature range (LEMO: -50°C to 150°C; ODU: -50°C to 120°C), current rating (LEMO: 2A; ODU: 2.5A), and series designation (LEMO 2P; ODU MEDI-SNAP®). Both share identical shell material, contact finish, termination method, and ingress protection rating.

Q: Are both parts suitable for medical applications?

A: Yes. Both the PAA.M1.4GL.AC65Z and S21MA7-P14MCC0-657S are listed for medical applications and are ROHS3 compliant with REACH unaffected status.

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

A: Both connectors accept cable diameters of 0.209" to 0.256" (5.30mm to 6.50mm). This specification is identical for both parts.

Q: Do these connectors require specific mating receptacles?

A: Yes. The LEMO PAA.M1.4GL.AC65Z mates with LEMO 2P series receptacles. The ODU S21MA7-P14MCC0-657S mates with ODU MEDI-SNAP® series receptacles. Mating receptacles are not interchangeable between manufacturers.

Q: What is the solder cup termination method?

A: Solder cup termination allows direct soldering of cable conductors into the connector contact cups. This method is suitable for applications requiring permanent, high-reliability connections without additional crimping or assembly steps.

Q: Are both parts available in bulk packaging?

A: The LEMO part is available in standard packaging with 801 units in stock. The ODU part is available in bulk packaging with 677 units in stock. Packaging format should be confirmed with the supplier based on assembly requirements.
