Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M1.4GL.AC39Z is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Must be Plug with Male Pins, 14-position configuration
• Termination Method: Solder Cup termination required
• Shell Material & Insert Material: Polysulfone (PSU) shell with Polyetheretherketone (PEEK) insert
• Contact Finish: Gold plating on mating surfaces
• Mounting Configuration: Free Hanging (In-Line) orientation
• Ingress Protection: IP50 minimum dust protection
• Mechanical Interface: Compatible cable opening range (0.106" ~ 0.154")
• Compliance: ROHS3 compliant, REACH unaffected status

The identified substitute part S21MA7-P14MCC0-397S meets these core substitution criteria while maintaining functional equivalence for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.4GL.AC39Z and S21MA7-P14MCC0-397S are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in industrial, medical, and automotive environments.

The PAA.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 full temperature range or where detent lock engagement is a functional requirement.

The S21MA7-P14MCC0-397S offers a higher current rating of 2.5A compared to the 2A specification of the primary part, with an operating temperature range of -50°C to 120°C. This substitute is suitable for applications operating within the 120°C upper temperature limit where the increased current capacity provides design margin.

Both connectors maintain identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring physical and electrical compatibility within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the S21MA7-P14MCC0-397S be used as a direct replacement for the PAA.M1.4GL.AC39Z?

A: The S21MA7-P14MCC0-397S is mechanically and electrically compatible for applications operating at temperatures up to 120°C. Applications requiring operation above 120°C or requiring detent lock fastening must use the PAA.M1.4GL.AC39Z.

Q: What is the significance of the detent lock feature on the PAA.M1.4GL.AC39Z?

A: The detent lock provides positive mechanical engagement between mating connectors. Applications requiring positive locking should specify the PAA.M1.4GL.AC39Z. The S21MA7-P14MCC0-397S uses push-pull fastening without detent lock.

Q: Are both parts suitable for medical device applications?

A: Both parts list medical applications in their specifications and maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), making them suitable for medical device applications within their respective operating parameters.

Q: What is the difference in current rating between these parts?

A: The PAA.M1.4GL.AC39Z is rated for 2A maximum current, while the S21MA7-P14MCC0-397S is rated for 2.5A. The higher rating of the substitute part provides additional design margin for applications requiring sustained current flow.

Q: How do the operating temperature ranges differ?

A: The PAA.M1.4GL.AC39Z operates from -50°C to 150°C, while the S21MA7-P14MCC0-397S operates from -50°C to 120°C. Applications requiring sustained operation above 120°C must use the PAA.M1.4GL.AC39Z.

Q: Are the cable opening specifications identical?

A: Yes, both connectors accept cable diameters in the range of 0.106" to 0.154" (2.70mm to 3.90mm), ensuring compatibility with the same cable specifications.
