Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.4GL.AC52R is determined by strict alignment of the following critical parameters:

• Connector type (Plug, Male Pins)
• Number of positions (4)
• Termination method (Solder Cup)
• Fastening mechanism (Push-Pull)
• Shell material (Polysulfone PSU)
• Contact finish (Gold)
• Ingress protection rating (IP50)
• Cable opening dimensions (0.157" ~ 0.205" / 4.00mm ~ 5.20mm)
• Insert material (PEEK)
• Mounting configuration (Free Hanging, In-Line)

The substitute part S11MA7-P04MJG0-5220 (ODU MEDI-SNAP®) meets all critical substitution criteria. Variations in current rating (10A vs. 8A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) represent enhanced or equivalent performance characteristics that do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC52R and S11MA7-P04MJG0-5220 are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The PAA.M0.4GL.AC52R supports an extended operating temperature range of -50°C to 150°C, making it suitable for high-temperature applications. The S11MA7-P04MJG0-5220 operates within -50°C to 120°C and provides a higher current rating of 10A compared to the 8A rating of the LEMO part. Both connectors maintain identical mechanical and electrical interface specifications, including shell size, termination method, fastening mechanism, and contact finish.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P04MJG0-5220 be used as a direct replacement for PAA.M0.4GL.AC52R?

A: Yes, the S11MA7-P04MJG0-5220 is mechanically and electrically compatible with the PAA.M0.4GL.AC52R. Both connectors share identical 4-position solder cup termination, push-pull fastening, PSU shell material, gold contact finish, and IP50 ingress protection. The substitute part meets all critical interface requirements.

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

A: The primary differences are current rating and maximum operating temperature. The PAA.M0.4GL.AC52R is rated for 8A and operates to 150°C, while the S11MA7-P04MJG0-5220 is rated for 10A and operates to 120°C. The ODU part includes detent lock fastening as a standard feature within its push-pull mechanism.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the PAA.M0.4GL.AC52R and S11MA7-P04MJG0-5220 are ROHS3 compliant and REACH unaffected.

Q: What cable opening dimensions are supported?

A: Both connectors support cable openings of 0.157" to 0.205" (4.00mm to 5.20mm), ensuring compatibility with standard cable assemblies designed for this connector family.

Q: Which part should be selected for high-temperature applications?

A: The PAA.M0.4GL.AC52R is recommended for applications requiring operation above 120°C, as it supports temperatures up to 150°C. The S11MA7-P04MJG0-5220 is suitable for applications within the -50°C to 120°C range.

Q: Are both parts available in the same packaging?

A: The PAA.M0.4GL.AC52R is available in standard packaging, while the S11MA7-P04MJG0-5220 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.
