Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.5GL.AC39G is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Must be Plug with Male Pins in 5-position configuration
• Termination Method: Solder Cup termination required for direct circuit board integration
• Contact Finish: Gold-plated mating contacts for corrosion resistance and signal integrity
• Shell Material: Polysulfone (PSU) construction for mechanical durability and thermal stability
• Fastening Mechanism: Push-Pull with Detent Lock for secure mating and unmating
• Ingress Protection: IP50 minimum rating for dust protection in industrial and medical environments
• Current & Temperature Ratings: Minimum 7A current capacity and operating range compatibility
• Cable Opening Specification: 0.106" ~ 0.154" (2.70mm ~ 3.90mm) for cable strain relief compatibility
• Compliance: ROHS3 compliance and active product status required

The substitute part S11MA7-P05MJG0-3970 meets all critical substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.5GL.AC39G and S11MA7-P05MJG0-3970 are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial, medical, and automotive applications.

The PAA.M0.5GL.AC39G operates across a wider temperature range (-50°C to 150°C) compared to the ODU substitute (-50°C to 120°C). Selection between these parts should be based on the specific operating temperature requirements of the target application. For applications operating above 120°C, the LEMO part is required. For applications within the -50°C to 120°C range, both parts are functionally equivalent.

The ODU S11MA7-P05MJG0-3970 provides a marginally higher current rating (7.5A versus 7A), which may offer additional design margin in high-current applications. Both connectors share identical cable opening specifications, shell materials, contact finishes, and ingress protection ratings, ensuring mechanical and electrical interchangeability within the specified temperature operating window.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P05MJG0-3970 be used as a direct replacement for the PAA.M0.5GL.AC39G?

A: Yes, within the operating temperature range of -50°C to 120°C. Both connectors share identical 5-position solder cup termination, gold-plated contacts, polysulfone shells, push-pull fastening, IP50 ingress protection, and cable opening specifications. The LEMO part supports higher temperatures up to 150°C.

Q: What are the key differences between these two connector models?

A: The primary differences are the manufacturer (LEMO versus ODU MEDI-SNAP® series), maximum operating temperature (150°C versus 120°C), and current rating (7A versus 7.5A). All other electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with the shell size or insert specifications?

A: No. The PAA.M0.5GL.AC39G uses shell size M05, while the ODU part uses shell size 1. Both accommodate the same cable opening range (0.106" ~ 0.154" / 2.70mm ~ 3.90mm) and are mechanically compatible for solder cup termination applications.

Q: Which part should be selected for medical device applications?

A: Both parts are suitable for medical applications, as indicated in their application lists. Selection should be based on the specific operating temperature requirements of the medical device. The LEMO part is preferred for applications requiring operation above 120°C.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the PAA.M0.5GL.AC39G and S11MA7-P05MJG0-3970 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial, medical, and automotive markets.
