Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M0.4GL.AC52A are identified based on strict equivalence across the following critical parameters:

• Connector type: Plug with male pins
• Number of positions: 4
• Termination method: Solder cup
• Shell material: Polysulfone (PSU)
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP50 dust protection
• Fastening mechanism: Push-pull configuration
• Insert material: Polyetheretherketone (PEEK)
• Mounting style: Free hanging (in-line)
• Backshell feature: Present
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part S11MA7-P04MJG0-5260 (ODU MEDI-SNAP® series) meets these core substitution criteria. Variations in current rating (10A vs. 8A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) represent differences in performance envelope rather than incompatibility for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC52A and S11MA7-P04MJG0-5260 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and automotive applications.

The PAA.M0.4GL.AC52A supports an extended operating temperature range of -50°C to 150°C, making it suitable for high-temperature environments. The S11MA7-P04MJG0-5260 operates within -50°C to 120°C, which covers standard industrial and medical temperature requirements.

Current rating differences (8A vs. 10A) should be evaluated against actual circuit requirements. The ODU substitute provides higher current capacity, which may offer design margin in power distribution applications.

Both connectors feature identical cable opening specifications, shell materials, contact finishes, and ingress protection ratings, ensuring mechanical and electrical compatibility in standard mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P04MJG0-5260 be used as a direct replacement for PAA.M0.4GL.AC52A?

A: Yes, for applications operating within -50°C to 120°C and requiring up to 10A current capacity. Both connectors share identical mechanical interfaces, termination methods, and shell specifications. Verify application temperature and current requirements before substitution.

Q: What is the difference between shell size designations M04 and 1?

A: These represent different manufacturer nomenclature systems for the same physical shell size. Both connectors accommodate 4-position configurations with identical cable opening ranges (4.00mm ~ 5.20mm).

Q: Are the fastening mechanisms equivalent?

A: Both use push-pull fastening. The PAA.M0.4GL.AC52A specifies "Push-Pull, Detent Lock" while the S11MA7-P04MJG0-5260 specifies "Push-Pull." Verify detent lock functionality requirements for your application before substitution.

Q: Do both parts meet medical device requirements?

A: Both are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status. Consult application-specific medical device standards and supplier documentation for complete qualification requirements.

Q: What is the inventory status for each part?

A: PAA.M0.4GL.AC52A has 849 units in stock. S11MA7-P04MJG0-5260 has 1003 units in stock, both as new original components.
