Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PT01E20-16S-SR are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector type: Receptacle with female sockets
• Number of positions: 16
• Shell size designation: 20-16
• Mounting configuration: Free hanging in-line
• Fastening mechanism: Bayonet lock
• Series standard: MIL-DTL-26482 style connectors
• Operating temperature range: -55°C to 125°C
• Ingress protection classification: Environment resistant

The MSW01E20-16S-SR qualifies as a substitute part because it maintains all primary compatibility parameters. Differences in contact finish material (cadmium versus gold), shell finish specification (cadmium versus olive drab chromate over cadmium), and termination detail (solder versus solder cup) represent acceptable variations within the MIL-DTL-26482 standard framework for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the PT01E20-16S-SR and MSW01E20-16S-SR maintain Active product status, indicating ongoing manufacturer support and availability. Both parts are RoHS non-compliant, consistent with military-specification circular connector standards.

The PT01E20-16S-SR features gold contact finish mating surfaces and olive drab chromate over cadmium shell finish, specifications typical for aerospace and military applications requiring enhanced corrosion resistance and contact reliability.

The MSW01E20-16S-SR provides cadmium contact finish and cadmium shell finish with documented current rating of 13A and voltage rating of 800V. This substitute maintains the core mechanical and electrical interface compatibility required for MIL-DTL-26482 style 16-position receptacle applications.

Selection between these parts should be based on specific application requirements regarding contact finish performance, environmental exposure conditions, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the MSW01E20-16S-SR directly replace the PT01E20-16S-SR in existing assemblies?

A: Both connectors share identical shell size (20-16), position count (16), mounting type (free hanging in-line), and fastening mechanism (bayonet lock). Physical and mechanical interface compatibility is maintained. Differences in contact finish material and shell finish specification should be evaluated against application-specific environmental and performance requirements.

Q: What is the significance of the contact finish difference between gold and cadmium?

A: Contact finish material affects mating surface durability, corrosion resistance, and electrical performance under specific environmental conditions. Gold provides superior corrosion resistance and contact reliability in high-reliability applications. Cadmium finish is acceptable for military applications per MIL-DTL-26482 specifications but may have different performance characteristics in specific environmental exposures.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the PT01E20-16S-SR and MSW01E20-16S-SR are rated for -55°C to 125°C operating temperature range, ensuring thermal compatibility across standard military and industrial applications.

Q: What does "26482 Style Connectors" mean for the MSW01E20-16S-SR?

A: This designation indicates the substitute part conforms to the design and performance requirements of MIL-DTL-26482 military specification for circular connectors. The PT01E20-16S-SR is explicitly designated as MIL-DTL-26482 Series I, PT. Both parts meet this standard framework.

Q: Are there any RoHS compliance considerations for substitution?

A: Both parts are RoHS non-compliant. If RoHS compliance is required for your application, neither part is suitable, and alternative components must be sourced.
