Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT00A20-16P-SR is determined by the following critical parameters:

• Connector Type & Pin Configuration: Receptacle with male pins
• Position Count: 16 positions
• Shell Size: 20-16 insert designation
• Mounting Configuration: Panel mount with flange
• Fastening Mechanism: Bayonet lock
• Termination Method: Solder-based connection
• Operating Environment: Temperature range -55°C to 125°C
• Electrical Performance: Voltage rating compatibility

The MSW00A20-16P-SR qualifies as a substitute based on alignment across these core parameters. Both connectors share identical position count, shell size, mounting type, fastening mechanism, and operating temperature range. Both employ solder termination and maintain bayonet lock fastening. Voltage rating differences and contact finish variations are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the PT00A20-16P-SR and MSW00A20-16P-SR are active products with established manufacturing status. Selection between these parts should be based on the following provided specifications:

Voltage Requirements: The PT00A20-16P-SR supports 1000VAC operation, while the MSW00A20-16P-SR is rated for 800V. Applications requiring the full 1000VAC rating must use the Amphenol part.

Contact Finish: The PT00A20-16P-SR features gold-plated mating contacts with olive drab chromate finish over cadmium shell plating. The MSW00A20-16P-SR uses cadmium contact finish. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Current Capacity: The MSW00A20-16P-SR specifies 13A current rating. The PT00A20-16P-SR does not provide a current specification in available documentation.

Compliance Status: Both parts are RoHS non-compliant and carry ECCN EAR99 classification. Both are affected by REACH regulations.

Inventory Availability: PT00A20-16P-SR maintains 762 units in stock; MSW00A20-16P-SR maintains 1033 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the MSW00A20-16P-SR directly replace the PT00A20-16P-SR in all applications?

A: Direct replacement is possible for applications operating at 800V or below. Applications requiring 1000VAC operation must use the PT00A20-16P-SR. Contact finish differences (gold versus cadmium) may affect performance in corrosive or high-reliability environments.

Q: What are the key compatibility factors between these connectors?

A: Both connectors share identical mechanical interfaces: 16-position configuration, 20-16 shell size, panel mount flange, bayonet lock fastening, and -55°C to 125°C operating range. These parameters ensure physical and functional interchangeability at the connector interface level.

Q: How do the shell finishes differ between these parts?

A: The PT00A20-16P-SR uses olive drab chromate over cadmium plating with gold-plated contacts. The MSW00A20-16P-SR uses cadmium shell finish with cadmium contact finish. Chromate conversion coating provides additional corrosion protection in aerospace and harsh industrial environments.

Q: Are there packaging differences between these substitute parts?

A: The PT00A20-16P-SR packaging is not specified in available data. The MSW00A20-16P-SR is supplied in bag packaging.

Q: What compliance considerations apply to both parts?

A: Both parts are RoHS non-compliant and REACH-affected. Both carry ECCN EAR99 classification. Applications subject to RoHS or REACH requirements cannot use either part without documented exemptions.

Q: Which part should be selected for maximum voltage headroom?

A: The PT00A20-16P-SR with 1000VAC rating provides 200V additional margin over the MSW00A20-16P-SR 800V rating. Selection depends on application voltage requirements and design safety margins.
