Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P04MJG0-5250 (ODU MEDI-SNAP®) is classified as a direct equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Plug, Male Pins
• Number of positions: 4
• Termination method: Solder Cup
• Mounting type: Free Hanging (In-Line)
• Shell material: Polysulfone (PSU)
• Contact finish: Gold
• Ingress protection: IP50 - Dust Protected
• Cable opening: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

Allowable Variations:

• Shell size insert: M04 (LEMO) vs. 1 (ODU) — different manufacturer sizing nomenclature for equivalent mechanical interface
• Current rating: 8A (LEMO) vs. 10A (ODU) — substitute supports higher current capacity
• Operating temperature: -50°C ~ 150°C (LEMO) vs. -50°C ~ 120°C (ODU) — substitute operates within a narrower upper temperature range
• Fastening type: Push-Pull, Detent Lock (LEMO) vs. Push-Pull (ODU) — substitute uses push-pull mechanism without detent lock feature

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC52V and S11MA7-P04MJG0-5250 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

The PAA.M0.4GL.AC52V offers a detent lock fastening mechanism and extended upper operating temperature range to 150°C. Selection of this part is appropriate for applications requiring mechanical locking assurance or operation in elevated temperature environments.

The S11MA7-P04MJG0-5250 provides equivalent mechanical and electrical interface compatibility with a higher current rating of 10A. This substitute is suitable for applications where the 8A current capacity of the primary part is insufficient, provided the operating temperature does not exceed 120°C and the absence of a detent lock mechanism is acceptable for the application design.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P04MJG0-5250 be used as a direct replacement for PAA.M0.4GL.AC52V?

A: The S11MA7-P04MJG0-5250 is mechanically and electrically compatible for applications where the operating temperature remains below 120°C and the push-pull fastening mechanism without detent lock is acceptable. The higher current rating of 10A supports all applications within the 8A specification of the primary part.

Q: What is the difference in fastening mechanisms between these two connectors?

A: The PAA.M0.4GL.AC52V uses a push-pull fastening type with detent lock, providing mechanical locking engagement. The S11MA7-P04MJG0-5250 uses push-pull fastening without detent lock, requiring manual disengagement without mechanical locking assistance.

Q: Are both connectors suitable for medical device applications?

A: Both connectors are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status. Application suitability depends on specific design requirements including temperature range, current demands, and fastening mechanism requirements.

Q: What is the significance of the different shell size nomenclature (M04 vs. 1)?

A: M04 (LEMO) and 1 (ODU) represent manufacturer-specific sizing designations for equivalent 4-position circular connector interfaces. Both designations refer to the same mechanical insert size and are compatible for mating purposes.

Q: Does the higher current rating of the ODU part affect compatibility?

A: No. The S11MA7-P04MJG0-5250 with a 10A rating is fully compatible with applications designed for 8A operation. The higher rating indicates greater current capacity without affecting electrical or mechanical interface compatibility.

Q: What is the operating temperature limitation when using the ODU substitute?

A: The S11MA7-P04MJG0-5250 operates within -50°C to 120°C. Applications requiring sustained operation above 120°C must use the PAA.M0.4GL.AC52V, which is rated to 150°C.
