Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSW02E12-8P are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector type: Receptacle with male pins
• Position count: 8 positions
• Shell size designation: 12-8
• Mounting configuration: Panel mount with flange
• Termination method: Solder cup
• Fastening mechanism: Bayonet lock
• Operating temperature range: -55°C to 125°C

The substitute parts MS3112E12-8P and PT02E-12-8P satisfy all primary compatibility criteria. Both are 8-position circular connector receptacles with male pins, 12-8 shell size, panel mount flange configuration, solder cup termination, and bayonet lock fastening. Both operate across the same temperature range and are classified as active products suitable for military applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MSW02E12-8P, MS3112E12-8P, and PT02E-12-8P—are active products with identical core electrical and mechanical specifications for 8-position circular connector receptacles with 12-8 shell size, panel mount flange, solder cup termination, and bayonet lock fastening.

MSW02E12-8P (Milspecwest, LLC): Primary part with cadmium contact finish and cadmium shell finish. Rated for 7.5A at 800V. RoHS non-compliant. ECCN classification EAR99. Current inventory: 814 pieces.

MS3112E12-8P (Souriau-Sunbank by Eaton): Substitute part with gold contact finish and olive drab color. Belongs to KPT series. RoHS non-compliant. Current inventory: 1433 pieces.

PT02E-12-8P (Amphenol Industrial Operations): Substitute part with gold contact finish, olive drab chromate over cadmium shell finish, and environment sealed ingress protection. Complies with MIL-DTL-26482 Series I specification. RoHS non-compliant. REACH affected. ECCN classification EAR99. Current inventory: 1254 pieces.

Selection between these parts depends on specific application requirements regarding contact finish material, shell finish specifications, and ingress protection level. All parts maintain compatibility with the same mating connectors and installation footprints.

Frequently Asked Questions (FAQ)

Q: Can MS3112E12-8P be used as a direct replacement for MSW02E12-8P?

A: MS3112E12-8P is mechanically and electrically compatible as a substitute. Both are 8-position receptacles with 12-8 shell size, panel mount flange, solder cup termination, and bayonet lock fastening. The primary difference is the contact finish material: MS3112E12-8P uses gold plating versus cadmium on the MSW02E12-8P. This difference does not affect mechanical interchangeability but may impact corrosion resistance and contact resistance characteristics in specific environments.

Q: What is the difference between PT02E-12-8P and the other two parts?

A: PT02E-12-8P shares the same core mechanical and electrical specifications as MSW02E12-8P and MS3112E12-8P. Key distinctions include gold contact finish, environment sealed ingress protection rating, and explicit compliance with MIL-DTL-26482 Series I specification. The shell finish is olive drab chromate over cadmium rather than solid cadmium.

Q: Are all three parts suitable for military applications?

A: Yes. MSW02E12-8P is specified for military applications. MS3112E12-8P and PT02E-12-8P are both active products with military-grade specifications and are suitable for military, aerospace, industrial, instrumentation, and mass transit applications.

Q: Do these connectors meet RoHS compliance requirements?

A: No. All three parts—MSW02E12-8P, MS3112E12-8P, and PT02E-12-8P—are RoHS non-compliant due to cadmium and other restricted substances in their construction.

Q: What is the operating temperature range for these connectors?

A: MSW02E12-8P and PT02E-12-8P both operate across -55°C to 125°C. Operating temperature data for MS3112E12-8P is not specified in available documentation.

Q: Can these receptacles be used interchangeably in the same circuit?

A: Yes, provided the application does not have specific requirements for contact finish material, shell finish, or ingress protection level. All three parts maintain identical pin configurations, mounting footprints, and fastening mechanisms, ensuring mechanical and electrical interchangeability in standard applications.

Q: What is the current and voltage rating for PT02E-12-8P?

A: Current and voltage ratings for PT02E-12-8P are not specified in available documentation. MSW02E12-8P is rated for 7.5A at 800V.
