Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P02MPH0-3960 (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: 2
• Termination method: Solder Cup
• Fastening mechanism: Push-Pull
• Contact finish: Gold
• Ingress protection: IP50 - Dust Protected
• Cable opening range: 0.106" ~ 0.154" (2.70mm ~ 3.90mm)
• Shell material: Polysulfone (PSU)
• Insert material: Polyetheretherketone (PEEK)
• Mounting type: Free Hanging (In-Line)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Current rating: 10A (main part) vs. 14A (substitute) — substitute exceeds requirement
• Operating temperature: -50°C ~ 150°C (main part) vs. -50°C ~ 120°C (substitute) — main part has extended upper range
• Shell size designation: M02 (main part) vs. 1 (substitute) — different manufacturer nomenclature for equivalent mechanical envelope
• Fastening type detail: Push-Pull, Detent Lock (main part) vs. Push-Pull (substitute) — substitute maintains push-pull functionality

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.2GL.AC39A and S11MA7-P02MPH0-3960 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.M0.2GL.AC39A maintains a higher operating temperature ceiling of 150°C compared to the ODU substitute at 120°C. Applications requiring sustained operation above 120°C must use the LEMO part.

The S11MA7-P02MPH0-3960 provides a higher current rating of 14A versus the 10A specification of the LEMO connector. For applications operating at or near the 10A limit, the ODU substitute offers additional thermal margin.

Both connectors share identical cable opening specifications, shell materials, and insert materials, ensuring mechanical and thermal compatibility in equivalent form factors.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P02MPH0-3960 be used as a direct replacement for the PAA.M0.2GL.AC39A?

A: Yes, for applications operating within -50°C to 120°C and at or below 10A current draw. The substitute maintains identical connector type, position count, termination method, contact finish, ingress protection, and mechanical envelope. Applications requiring operation above 120°C must use the LEMO part.

Q: What is the difference in shell size designation between M02 and 1?

A: M02 (LEMO nomenclature) and 1 (ODU nomenclature) represent equivalent mechanical envelope sizes for 2-position circular connectors. The physical dimensions and mating interfaces are compatible.

Q: Does the ODU substitute include detent lock fastening?

A: The S11MA7-P02MPH0-3960 features push-pull fastening. The LEMO part specifies push-pull with detent lock. Both provide secure mating; the detent lock adds mechanical retention. Application requirements determine if detent lock functionality is necessary.

Q: Are both parts suitable for medical device applications?

A: Yes. Both the PAA.M0.2GL.AC39A and S11MA7-P02MPH0-3960 are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for medical device component selection.

Q: What is the inventory status for each part?

A: PAA.M0.2GL.AC39A: 839 units in stock. S11MA7-P02MPH0-3960: 852 units in stock. Both parts are available as new original stock.
