Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT07E-8-4S(SR) is determined by the following critical parameters:

• Number of Positions: Must be 4 positions to maintain electrical interface compatibility
• Shell Size - Insert: Must be 8-4 to ensure mechanical fit and mating compatibility
• Connector Category: Must be classified as a circular connector to preserve form factor and mounting requirements
• Connector Type: Must support the same gender and socket configuration as the original part

The substitute part MSW07E8-4S-SR meets these core substitution criteria. Both parts share identical position count (4), shell size (8-4), and circular connector classification. The MSW07E8-4S-SR is manufactured by Milspecwest, LLC and is available with 1040 units in inventory, providing an alternative sourcing option while maintaining mechanical and electrical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the PT07E-8-4S(SR) and MSW07E8-4S-SR maintain active product status, confirming ongoing manufacturer support and availability. Selection between these parts should be based on the following engineering considerations:

PT07E-8-4S(SR) is the primary specification and should be used when Amphenol Industrial Operations sourcing is required or preferred for supply chain consistency.

MSW07E8-4S-SR serves as a qualified substitute when alternative sourcing from Milspecwest, LLC is acceptable. This part provides equivalent mechanical interface compatibility (4 positions, 8-4 shell size) and is available with substantial inventory (1040 units). The substitute part specifies additional electrical parameters (7.5A current rating, 800V voltage rating) and operating temperature range (-55°C ~ 125°C), which may be relevant for application-specific requirements.

Both parts are RoHS non-compliant, indicating they contain materials restricted under RoHS directives and should be evaluated against applicable regulatory requirements for the intended application.

Frequently Asked Questions (FAQ)

Q: What makes MSW07E8-4S-SR a valid substitute for PT07E-8-4S(SR)?

A: Both parts share the critical substitution parameters: 4-position configuration and 8-4 shell size. These parameters determine mechanical fit and electrical interface compatibility in circular connector applications. Both are classified as circular connectors and maintain active product status.

Q: Are there differences in connector type between these parts?

A: The PT07E-8-4S(SR) is specified as a receptacle, while the MSW07E8-4S-SR is specified as a plug with female sockets. This distinction affects mating compatibility and should be verified against the complementary connector in the application circuit.

Q: What is the difference in packaging between these parts?

A: The PT07E-8-4S(SR) is supplied in bulk packaging, while the MSW07E8-4S-SR is supplied in bag packaging. Packaging differences do not affect electrical or mechanical performance but may impact handling, storage, and inventory management procedures.

Q: Are both parts suitable for military applications?

A: The MSW07E8-4S-SR is specified for military applications. The PT07E-8-4S(SR) does not include military application designation in the provided specifications. Application suitability should be confirmed against specific military standards and requirements.

Q: What are the compliance considerations for these parts?

A: Both parts are RoHS non-compliant. The MSW07E8-4S-SR specifies ECCN classification as EAR99 and REACH status as vendor undefined. Compliance verification against applicable regulations for the intended application is required before selection.
