Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P05MJG0-3960 (ODU MEDI-SNAP®) is grouped as an equivalent based on the following critical parameters that determine substitution compatibility:

• Connector Configuration: Both parts are 5-position circular connector plugs with male pins
• Termination Method: Both use solder cup termination
• Shell Material: Both feature Polysulfone (PSU) construction
• Contact Finish: Both have gold-plated mating surfaces
• Mounting Type: Both are free hanging (in-line) configurations
• Fastening Mechanism: Both use push-pull fastening with detent lock
• Ingress Protection: Both meet IP50 dust protection rating
• Cable Opening Range: Both accommodate 0.106" ~ 0.154" (2.70mm ~ 3.90mm) cable diameters
• Insert Material: Both use Polyetheretherketone (PEEK)
• Compliance: Both are ROHS3 compliant and REACH unaffected

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.5GL.AC39A and S11MA7-P05MJG0-3960 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.M0.5GL.AC39A offers a wider operating temperature range (-50°C to 150°C) and includes a detent lock fastening feature, making it preferable for applications requiring extended thermal performance or enhanced mechanical retention.

The S11MA7-P05MJG0-3960 provides a higher current rating (7.5A versus 7A) and operates within the -50°C to 120°C range, suitable for applications where the lower temperature ceiling is acceptable and higher current capacity is beneficial.

Selection between these parts should be based on specific application requirements regarding operating temperature limits, current demands, and fastening mechanism preferences.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P05MJG0-3960 be used as a direct replacement for PAA.M0.5GL.AC39A?

A: Both parts share identical core specifications for connector type, position count, termination method, shell material, contact finish, ingress protection, and cable opening dimensions. However, the PAA.M0.5GL.AC39A operates to 150°C while the ODU part is rated to 120°C maximum. If your application requires operation above 120°C, the LEMO part is required. For applications within the 120°C limit, the ODU substitute is functionally compatible.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Operating temperature range—LEMO extends to 150°C versus ODU's 120°C maximum; (2) Current rating—ODU is rated 7.5A versus LEMO's 7A; (3) Fastening mechanism—LEMO includes detent lock while ODU uses standard push-pull. All other critical parameters including shell size, material composition, contact finish, and ingress protection are identical.

Q: Are both parts suitable for medical device applications?

A: Yes. Both parts are listed for medical applications, are ROHS3 compliant, and have MSL rating of 1 (Unlimited). Both are active production parts with established supply chains.

Q: What is the significance of the cable opening specification?

A: The cable opening range of 0.106" ~ 0.154" (2.70mm ~ 3.90mm) is identical for both parts, ensuring compatible backshell and cable strain relief configurations. This parameter must match your cable diameter for proper mechanical fit and environmental sealing.

Q: Does the difference in fastening type affect interchangeability?

A: The PAA.M0.5GL.AC39A includes a detent lock mechanism in addition to push-pull fastening, providing enhanced mechanical retention. The S11MA7-P05MJG0-3960 uses push-pull fastening without detent lock. If your application requires the detent lock feature for vibration resistance or mechanical security, the LEMO part is necessary. For standard push-pull applications, both are compatible.
