Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAB.M1.4GL.AC39Z are identified based on strict equivalence of the following critical parameters:

• Connector Configuration: 14-position plug with male pins
• Termination Method: Solder cup
• Shell Material: Polysulfone (PSU)
• Contact Finish: Gold plating on mating surfaces
• Mounting Style: Free hanging, in-line configuration
• Ingress Protection: IP50 dust protection rating
• Insert Material: Polyetheretherketone (PEEK)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part S21MC7-P14MCC0-397S meets these core electrical and mechanical requirements. Variations in fastening type (push-pull without detent lock), orientation designation, current rating (2.5A vs. 2A), and maximum operating temperature (120°C vs. 150°C) are noted as secondary differences that do not prevent functional substitution in applications within the overlapping operational envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the PAB.M1.4GL.AC39Z and S21MC7-P14MCC0-397S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications.

The PAB.M1.4GL.AC39Z provides a maximum operating temperature of 150°C and includes a detent lock fastening mechanism. Selection of this part is appropriate for applications requiring the extended temperature range or the additional mechanical security of the detent lock feature.

The S21MC7-P14MCC0-397S offers a higher current rating of 2.5A and operates to 120°C maximum. This substitute is suitable for applications operating within the -50°C to 120°C envelope where the increased current capacity is beneficial. The ODU MEDI-SNAP® series includes strain relief features in addition to backshell protection.

Both parts share identical cable opening specifications, shell material composition, contact finish, and ingress protection rating, ensuring mechanical and electrical compatibility in equivalent circuit designs.

Frequently Asked Questions (FAQ)

Q: Can S21MC7-P14MCC0-397S replace PAB.M1.4GL.AC39Z in all applications?

A: Substitution is valid for applications operating within the overlapping temperature range (-50°C to 120°C) and current requirements not exceeding 2A. Applications requiring operation above 120°C or the detent lock fastening mechanism must use the original PAB.M1.4GL.AC39Z specification.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share 14-position configuration, solder cup termination, gold-plated contacts, polysulfone shell material, PEEK inserts, IP50 ingress protection, and identical cable opening dimensions. These parameters ensure mechanical fit and electrical performance equivalence within specified operating conditions.

Q: Are there differences in fastening mechanisms?

A: The PAB.M1.4GL.AC39Z includes a detent lock in addition to push-pull fastening, while the S21MC7-P14MCC0-397S uses push-pull fastening only. This difference affects mechanical retention force but does not prevent functional substitution in applications where detent locking is not a requirement.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the PAB.M1.4GL.AC39Z and S21MC7-P14MCC0-397S are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for industrial and medical equipment.

Q: What is the significance of the current rating difference?

A: The S21MC7-P14MCC0-397S is rated for 2.5A versus 2A for the PAB.M1.4GL.AC39Z. The substitute part supports higher current capacity. Applications designed for 2A operation are compatible with the substitute; applications requiring current above 2A must use the substitute or verify the original part's capability.

Q: Are the orientation designations interchangeable?

A: The PAB.M1.4GL.AC39Z uses orientation B while the S21MC7-P14MCC0-397S uses orientation C. These designations reflect manufacturer-specific keying schemes. Physical compatibility must be verified against mating connector specifications before substitution.
