PT01E20-16P-SR Equivalent & Substitute Parts

Part Overview

The PT01E20-16P-SR is a 16-position circular connector receptacle manufactured by Amphenol Industrial Operations, designed for free-hanging in-line applications. This connector features male pins with solder cup termination and is compliant with MIL-DTL-26482 Series I specifications. The part is currently active in production with 958 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT01E20-16P-SR is determined by strict alignment of the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins)
• Position count (16 positions)
• Shell size designation (20-16)
• Mounting configuration (Free Hanging, In-Line)
• Fastening mechanism (Bayonet Lock)
• Shell material (Aluminum)
• Operating temperature range (-55°C ~ 125°C)
• Environmental protection classification (Environment Resistant)

The MSW01E20-16P-SR from Milspecwest, LLC meets these core substitution criteria. Both connectors conform to MIL-DTL-26482 style specifications and share identical mechanical interfaces and environmental ratings. Differences in contact finish plating and termination method details do not preclude functional equivalence in applications where the specified parameters are met.

Parameter Comparison

Engineering Selection Recommendations

Both the PT01E20-16P-SR and MSW01E20-16P-SR are active production components with confirmed inventory availability. Selection between these parts should be based on:

• Supply chain requirements and lead time constraints
• Procurement source preferences and established vendor relationships
• Compliance documentation requirements for specific applications
• Inventory levels at the time of component selection

Both connectors maintain identical MIL-DTL-26482 compliance and environmental ratings. Neither part carries RoHS compliance certification, which is consistent with military-specification circular connector standards. The operating temperature range, mechanical interface, and environmental protection ratings are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can MSW01E20-16P-SR be used as a direct replacement for PT01E20-16P-SR?

A: Yes. Both connectors share identical mechanical interfaces, position counts, shell sizes, mounting configurations, and operating temperature ranges. The bayonet lock fastening mechanism and aluminum shell construction are equivalent. Both maintain MIL-DTL-26482 compliance and environment-resistant ingress protection.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer identity and contact finish plating specifications. The PT01E20-16P-SR features gold mating contact finish, while the MSW01E20-16P-SR specifies cadmium contact finish. Both connectors use solder termination methods suitable for cable assembly applications.

Q: Are there any compliance or certification differences?

A: Both connectors are RoHS non-compliant and carry EAR99 ECCN classification. Neither part has RoHS certification, which is standard for military-specification connectors. Compliance documentation should be verified against specific application requirements.

Q: What mounting applications are these connectors suitable for?

A: Both connectors are configured for free-hanging in-line mounting, making them suitable for cable assembly applications in aerospace, communication systems, industrial equipment, instrumentation, and mass transit applications.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Interchangeability is determined by the specific application requirements. The mechanical and electrical parameters are equivalent. However, contact finish specifications and any application-specific certifications should be reviewed before substitution in production assemblies.
