Key Parameters

Substitute Part Grouping Explanation

The MSW01A20-16S from Milspecwest, LLC qualifies as a substitute for the PT01A-20-16S based on the following critical parameters that determine functional interchangeability:

• Number of Positions: Both parts feature 16 positions
• Shell Size - Insert: Both use 20-16 specification
• Connector Type: Both are receptacles with female sockets
• Fastening Type: Both employ bayonet lock mechanisms
• Termination Method: Both use solder termination
• Current Rating: Both rated at 13A
• Voltage Rating: Both rated at 800V
• Operating Temperature Range: Both operate from -55°C to 125°C

These aligned parameters establish the basis for substitution eligibility in circular connector applications requiring 16-position receptacle configurations with bayonet fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the PT01A-20-16S and MSW01A20-16S maintain active product status, indicating ongoing manufacturer support and availability. The MSW01A20-16S is classified as a 26482 Style Connector, which aligns with military-grade circular connector standards. The substitute part carries RoHS non-compliant status, consistent with military applications where legacy compliance requirements may differ from commercial standards. Selection between these parts should be based on supply availability, procurement lead times, and specific application compliance requirements. Both parts are suitable for military applications and operate within identical electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: What makes the MSW01A20-16S a valid substitute for the PT01A-20-16S?

A: Both connectors share identical critical specifications: 16-position configuration, 20-16 shell size, bayonet fastening, 13A current rating, 800V voltage rating, and -55°C to 125°C operating temperature range. These aligned parameters establish functional interchangeability for circular connector applications.

Q: Are there differences in packaging between these parts?

A: The PT01A-20-16S is supplied in bulk packaging, while the MSW01A20-16S is supplied in bag packaging. This distinction affects handling and storage but does not impact electrical or mechanical compatibility.

Q: What is the significance of the 26482 Style designation on the MSW01A20-16S?

A: The 26482 Style designation indicates conformance to military connector standards. This classification ensures the part meets established military specifications for circular connectors, supporting applications requiring standardized military-grade components.

Q: How do the inventory levels compare?

A: The PT01A-20-16S has 1085 units in stock, while the MSW01A20-16S has 717 units available. Both represent adequate inventory for component sourcing, with selection dependent on immediate availability requirements.

Q: Are there compliance considerations when selecting between these parts?

A: Both parts are RoHS non-compliant, which is typical for military-grade circular connectors. Applications requiring RoHS compliance would require alternative component selection outside this substitution group.
