Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSW01E14-19P-SR with the PT01E-14-19P(SR) is based on equivalence across the following critical parameters:

Matching Electrical Specifications:

• Current Rating: 7.5A (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Connector Type: Receptacle, Male Pins (identical)
• Number of Positions: 19 (identical)

Matching Mechanical Specifications:

• Shell Size - Insert: 14-19 (identical)
• Mounting Type: Free Hanging (In-Line) (identical)
• Fastening Type: Bayonet Lock (identical)
• Shell Material: Aluminum (identical)
• Ingress Protection: Environment Resistant (identical)

Series Compatibility: Both connectors conform to MIL-DTL-26482 series specifications, establishing functional interchangeability within military circular connector applications.

Voltage Rating Consideration: The PT01E-14-19P(SR) operates at 600VAC, which is lower than the MSW01E14-19P-SR rating of 800V. This difference requires circuit-level voltage verification to ensure the substitute meets application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MSW01E14-19P-SR remains the specified component when the application circuit operates at or near 800V. Both the main part and substitute maintain Active product status, ensuring continued availability and manufacturing support.

Substitute Part Selection: The PT01E-14-19P(SR) serves as a qualified substitute when circuit voltage requirements do not exceed 600VAC. The substitute part is manufactured by Amphenol Industrial Operations, an established supplier within military and aerospace connector markets. Both parts comply with MIL-DTL-26482 series specifications and maintain identical current ratings, temperature ranges, and mechanical mounting characteristics.

Compliance Considerations: Both parts are classified as EAR99 under export control regulations. The MSW01E14-19P-SR is explicitly RoHS non-compliant. Selection between these parts should account for end-use application compliance requirements and supply chain constraints.

Inventory Availability: The MSW01E14-19P-SR maintains 733 pieces in stock, while the PT01E-14-19P(SR) maintains 713 pieces in stock, providing equivalent sourcing capacity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the PT01E-14-19P(SR) be used as a direct replacement for the MSW01E14-19P-SR?

A: The PT01E-14-19P(SR) is functionally equivalent for applications operating at 600VAC or below. The voltage rating difference (600VAC versus 800V) requires circuit-level verification. All other electrical and mechanical parameters are identical, including current rating, temperature range, connector type, position count, and mounting configuration.

Q: What is the primary difference between these two connector models?

A: The primary differences are manufacturer identity, voltage rating, and shell finish specification. The MSW01E14-19P-SR features a cadmium shell finish, while the PT01E-14-19P(SR) features an olive drab chromate over cadmium finish. The PT01E-14-19P(SR) includes a backshell feature not specified for the MSW01E14-19P-SR.

Q: Are both connectors suitable for military applications?

A: Yes. The MSW01E14-19P-SR is specified for military applications. The PT01E-14-19P(SR) is qualified for aerospace, industrial, instrumentation, mass transit, and military applications, providing broader application scope while maintaining military-grade specifications.

Q: What termination differences exist between these parts?

A: The MSW01E14-19P-SR uses solder termination, while the PT01E-14-19P(SR) uses solder cup termination. Both are solder-based termination methods suitable for cable assembly operations.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the MSW01E14-19P-SR and PT01E-14-19P(SR) operate across the identical temperature range of -55°C to 125°C.

Q: What is the significance of the MIL-DTL-26482 series designation?

A: MIL-DTL-26482 is the military specification governing circular connector design and performance. Both connectors conform to this specification, establishing compatibility within military and aerospace systems requiring standardized connector interfaces.

Q: Are there packaging differences between these parts?

A: The MSW01E14-19P-SR packaging is not specified in available documentation. The PT01E-14-19P(SR) is packaged in bags. Packaging differences do not affect functional compatibility but may influence handling and storage procedures.
