Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.4GL.AC52N is determined by the following critical parameters:

• Connector Configuration: 4-position plug with male pins and solder cup termination
• Shell Material & Finish: Polysulfone (PSU) construction with gold-plated contacts
• Fastening Mechanism: Push-pull detent lock system
• Mounting Profile: Free hanging in-line configuration
• Environmental Protection: IP50 dust protection rating
• Electrical Performance: Current rating and contact material compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part S11MA7-P04MJG0-5280 (ODU MEDI-SNAP®) meets these core substitution criteria through equivalent connector topology, matching shell material, identical termination method, and compatible fastening approach. Both parts maintain the same ingress protection rating, mounting configuration, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC52N and S11MA7-P04MJG0-5280 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in industrial, medical, and automotive sectors.

Primary Part Selection (PAA.M0.4GL.AC52N): Use when operating temperature requirements extend to 150°C or when LEMO series compatibility is specified in system design documentation.

Substitute Part Selection (S11MA7-P04MJG0-5280): Use when ODU MEDI-SNAP® series integration is acceptable and operating temperatures remain within the -50°C to 120°C range. The higher current rating (10A versus 8A) provides additional margin for applications operating at or near the 8A specification.

Both parts maintain identical mechanical interfaces, electrical contact configurations, and environmental protection ratings. Selection between these parts should be based on supply availability, design series standardization, and thermal operating envelope requirements.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P04MJG0-5280 be used as a direct replacement for the PAA.M0.4GL.AC52N?

A: Yes, for applications operating within -50°C to 120°C. Both connectors share identical 4-position solder cup configuration, PSU shell material, gold contact finish, IP50 protection, and push-pull fastening. The ODU part's 10A current rating exceeds the LEMO part's 8A rating, providing compatibility for standard-load applications. Applications requiring operation above 120°C must use the LEMO part.

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

A: The primary differences are manufacturer series (LEMO 1P versus ODU MEDI-SNAP®), maximum operating temperature (150°C versus 120°C), and current rating (8A versus 10A). All other electrical, mechanical, and environmental specifications are equivalent.

Q: Are both parts suitable for medical device applications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and listed for medical applications. Both maintain MSL 1 (unlimited moisture sensitivity level) and identical ingress protection ratings.

Q: What is the cable opening specification, and does it differ between parts?

A: Both parts accept cable diameters of 0.157" to 0.205" (4.00mm to 5.20mm). This specification is identical across both connectors.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Mechanical and electrical interchangeability is confirmed for the specified parameters. However, connector series standardization in existing designs should be evaluated. If the assembly is designed specifically for LEMO 1P series, substitution with ODU MEDI-SNAP® should be documented as an engineering change.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and HTSUS code 8536.69.4020.
