Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSW01A8-3S-SR is based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 3
• Shell Size - Insert: 8-3
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Series Compliance: MIL-DTL-26482 Style

Compatible Electrical Parameters:

• Operating Temperature Range: -55°C to 125°C
• Voltage Rating: 800V minimum

The substitute part PT01A-8-3S(SR) manufactured by Amphenol Industrial Operations meets all mandatory matching parameters and operates within the same temperature range. Both parts are classified as Active product status and are RoHS non-compliant with EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

Both the MSW01A8-3S-SR and PT01A-8-3S(SR) are Active product status connectors compliant with MIL-DTL-26482 specifications. Selection between these parts is based on the following engineering considerations:

MSW01A8-3S-SR Selection Criteria:

• Primary sourcing option with 903 pieces in stock
• Cadmium shell finish and contact finish
• Specified current rating of 7.5A and voltage rating of 800V
• Military application designation

PT01A-8-3S(SR) Selection Criteria:

• Alternative sourcing with 929 pieces in stock
• Enhanced contact finish (Gold) for improved corrosion resistance
• Broader application range including Aerospace, Industrial, Instrumentation, and Mass Transit

Both parts operate across the identical temperature range of -55°C to 125°C and maintain Bayonet Lock fastening with 3-position, 8-3 shell size configuration. The substitute part offers enhanced environmental protection through gold plating and additional mechanical features while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PT01A-8-3S(SR) be used as a direct replacement for MSW01A8-3S-SR?

A: Yes. Both connectors share identical mechanical and electrical specifications including 3-position configuration, 8-3 shell size, Bayonet Lock fastening, Free Hanging mounting type, and -55°C to 125°C operating temperature range. Both comply with MIL-DTL-26482 specifications.

Q: What are the differences in contact finish between these parts?

A: The MSW01A8-3S-SR features Cadmium contact finish at the mating interface. The PT01A-8-3S(SR) features Gold contact finish, which provides enhanced corrosion resistance and improved electrical performance in high-reliability applications.

Q: Are there differences in shell finish?

A: Yes. The MSW01A8-3S-SR has Cadmium shell finish. The PT01A-8-3S(SR) has Olive Drab Chromate over Cadmium shell finish, providing additional environmental protection.

Q: What is the significance of the solder versus solder cup termination designation?

A: Both parts utilize solder termination technology. The PT01A-8-3S(SR) specifically designates "Solder Cup" termination, which is a standard solder termination method compatible with the MSW01A8-3S-SR solder termination requirement.

Q: Do both parts meet the same voltage and current requirements?

A: The MSW01A8-3S-SR specifies 7.5A current rating and 800V voltage rating. The PT01A-8-3S(SR) does not provide explicit current and voltage ratings in the available data; however, both parts comply with MIL-DTL-26482 specifications for the 8-3 shell size configuration.

Q: What is the cable opening specification?

A: The PT01A-8-3S(SR) specifies a cable opening of 0.125" (3.18mm). The MSW01A8-3S-SR does not provide a cable opening specification in the available data.

Q: Are there packaging differences?

A: The MSW01A8-3S-SR is supplied in unspecified packaging. The PT01A-8-3S(SR) is supplied in Bulk packaging.

Q: What is the REACH compliance status?

A: The MSW01A8-3S-SR has Vendor Undefined REACH status. The PT01A-8-3S(SR) is REACH Affected, indicating it contains substances of concern and requires compliance documentation.

Q: What is the Moisture Sensitivity Level (MSL) for each part?

A: The MSW01A8-3S-SR has MSL classified as Not Applicable. The PT01A-8-3S(SR) has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
