Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT01A20-16S-SR is determined by strict alignment with the following critical parameters:

• Connector Type & Gender: Must be Receptacle with Female Sockets
• Position Count: Must be 16 positions
• Shell Size Designation: Must be 20-16 (Size 20 shell with 16-position insert)
• Mounting Configuration: Must support Free Hanging (In-Line) mounting
• Termination Method: Must be Solder or Solder Cup compatible
• Fastening Mechanism: Must use Bayonet Lock
• Shell Material: Must be Aluminum
• Temperature Rating: Must support -55°C ~ 125°C operating range
• Series Compliance: Must conform to MIL-DTL-26482 style specifications

The MSW01A20-16S-SR qualifies as a substitute part because it meets all critical parameters within the allowed tolerance for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the PT01A20-16S-SR and MSW01A20-16S-SR are Active product status components, ensuring ongoing manufacturer support and availability. Both parts are RoHS non-compliant, indicating they contain materials subject to RoHS restrictions and are suitable for applications where RoHS exemptions apply.

The PT01A20-16S-SR features gold mating contact finish and olive drab chromate over cadmium shell finish, providing enhanced corrosion resistance and contact reliability. The MSW01A20-16S-SR uses cadmium finish for both shell and contacts, with published electrical ratings of 13A current and 800V voltage.

Selection between these parts should be based on specific application requirements regarding contact finish specifications, shell finish durability requirements, and published electrical performance data availability.

Frequently Asked Questions (FAQ)

Q: Can the MSW01A20-16S-SR directly replace the PT01A20-16S-SR in existing designs?

A: Both connectors share identical mechanical interfaces (16 positions, 20-16 shell size, bayonet lock fastening, free-hanging mounting). The primary differences are contact finish (gold vs. cadmium) and shell finish specifications. Compatibility depends on whether the application requires the specific finish characteristics of the original part.

Q: What is the significance of the shell size designation "20-16"?

A: The "20-16" designation indicates a Size 20 shell with a 16-position insert. This determines the physical envelope and mating interface. Both substitute parts use identical shell sizing, ensuring mechanical interchangeability.

Q: Are there differences in termination between solder cup and solder termination?

A: Both termination methods are solder-based. Solder cup termination provides a cup-shaped receptacle for wire insertion and solder flow, while solder termination indicates general solder compatibility. Both are compatible with standard PCB assembly processes.

Q: What does MIL-DTL-26482 compliance mean for substitution?

A: MIL-DTL-26482 is the military specification for circular connectors. The PT01A20-16S-SR conforms to Series I of this specification, while the MSW01A20-16S-SR is described as "26482 Style," indicating design alignment with the specification family. Both parts meet the mechanical and electrical requirements for this connector class.

Q: Why are both parts RoHS non-compliant?

A: RoHS non-compliance indicates these connectors contain materials (such as cadmium plating) restricted under RoHS regulations. These parts are suitable for applications with RoHS exemptions, including aerospace, military, and industrial systems where performance and reliability requirements override RoHS restrictions.

Q: How do the electrical ratings compare?

A: The PT01A20-16S-SR does not specify current or voltage ratings in the provided data. The MSW01A20-16S-SR is rated for 13A current and 800V voltage. For applications requiring specific electrical performance verification, consult manufacturer datasheets or application notes.
