Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P05MJG0-5220 (ODU MEDI-SNAP®) is classified as an equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Plug, Male Pins
• Number of positions: 5
• Termination method: Solder Cup
• Shell material: Polysulfone (PSU)
• Contact finish: Gold
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Ingress protection: IP50 - Dust Protected
• Mounting type: Free Hanging (In-Line)
• Orientation: A
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Current rating: 7A (main) vs. 7.5A (substitute) — substitute exceeds minimum requirement
• Operating temperature: -50°C ~ 150°C (main) vs. -50°C ~ 120°C (substitute) — main part supports extended upper temperature range
• Fastening type: Push-Pull, Detent Lock (main) vs. Push-Pull (substitute) — substitute lacks detent lock feature
• Shell size designation: M05 (main) vs. 1 (substitute) — equivalent mechanical interface per manufacturer specifications

Parameter Comparison

Engineering Selection Recommendations

Both parts meet ROHS3 compliance and REACH unaffected status, qualifying them for regulated applications. The PAA.M0.5GL.AC52R remains the primary specification when applications require the detent lock fastening feature or operate at temperatures exceeding 120°C. The S11MA7-P05MJG0-5220 serves as a functional substitute for applications where the operating temperature maximum of 120°C is acceptable and detent lock functionality is not required. Both parts maintain identical mechanical interfaces, contact finishes, and ingress protection ratings, supporting direct substitution in compatible designs.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P05MJG0-5220 replace PAA.M0.5GL.AC52R in all applications?

A: Substitution is valid when application requirements do not mandate the detent lock fastening feature and maximum operating temperature does not exceed 120°C. The higher current rating of the substitute (7.5A vs. 7A) does not restrict compatibility.

Q: What is the significance of the different shell size designations (M05 vs. 1)?

A: Both designations refer to equivalent mechanical interfaces within their respective manufacturer specifications. The physical mating dimensions and contact arrangements are compatible.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is supplied in bulk packaging. This affects inventory management but does not impact electrical or mechanical performance.

Q: What applications are supported by both parts?

A: Both connectors support industrial, medical, and testing equipment applications. The main part additionally supports automotive applications; verify application requirements before substitution.

Q: How do the contact materials differ?

A: The main part contact material is not specified in available data. The substitute uses brass contacts with gold mating finish. Both maintain identical gold contact finish specifications for mating surfaces.
