Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.4GL.AC65Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug with male pins in 4-position configuration
• Termination Method: Solder cup termination required for PCB assembly compatibility
• Contact Finish: Gold plating for mating surface ensures consistent electrical performance
• Fastening Mechanism: Push-pull connection type for mechanical compatibility
• Ingress Protection: IP50 rating for dust protection in specified environments
• Operating Temperature: Must support the required thermal range
• Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part S21MA7-P04MJG0-657S meets these core substitution criteria while maintaining functional equivalence for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC65Z and S21MA7-P04MJG0-657S are active production parts with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial, medical, and automotive applications.

The PAA.M0.4GL.AC65Z maintains a maximum operating temperature of 150°C, providing extended thermal capability for high-temperature environments. The S21MA7-P04MJG0-657S operates to 120°C maximum, suitable for standard industrial and medical applications within this temperature envelope.

The S21MA7-P04MJG0-657S provides a higher current rating of 10A compared to the 8A rating of the PAA.M0.4GL.AC65Z, offering additional margin for power delivery applications. Both parts feature identical cable opening specifications and matching shell and insert materials, ensuring mechanical and electrical compatibility in connector mating interfaces.

Selection between these parts should be based on specific application temperature requirements and current delivery specifications.

Frequently Asked Questions (FAQ)

Q: Can the S21MA7-P04MJG0-657S be used as a direct replacement for the PAA.M0.4GL.AC65Z?

A: Yes, for applications operating within the -50°C to 120°C temperature range. Both parts share identical 4-position solder cup termination, gold contact finish, IP50 ingress protection, and mechanical dimensions. Applications requiring operation above 120°C must use the PAA.M0.4GL.AC65Z.

Q: What are the key differences between these two connector models?

A: The primary differences are operating temperature range (PAA.M0.4GL.AC65Z: -50°C to 150°C; S21MA7-P04MJG0-657S: -50°C to 120°C) and current rating (PAA.M0.4GL.AC65Z: 8A; S21MA7-P04MJG0-657S: 10A). The fastening mechanism differs slightly, with the PAA.M0.4GL.AC65Z featuring detent lock in addition to push-pull, while the S21MA7-P04MJG0-657S uses push-pull only.

Q: Are both parts suitable for medical applications?

A: Yes. Both the PAA.M0.4GL.AC65Z and S21MA7-P04MJG0-657S are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status required for medical device integration.

Q: What is the significance of the cable opening specification?

A: The cable opening range of 0.209" to 0.256" (5.30mm to 6.50mm) is identical for both parts, ensuring compatibility with the same cable gauges and backshell configurations. This parameter is critical for mechanical assembly and strain relief integration.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
