Substitute Part Grouping Explanation

Substitution eligibility for the PT06A20-16P-SR is determined by the following critical parameters:

Connector Type & Pin Configuration: Plug with male pins
Position Count: 16 positions
Shell Size: 20-16 insert designation
Fastening Mechanism: Bayonet lock coupling
Termination Method: Solder-based connection
Mounting Configuration: Free hanging, in-line orientation
Environmental Rating: Operating temperature range -55°C to 125°C
Series Compliance: MIL-DTL-26482 style connectors

The MSW06A20-16P-SR meets these core substitution criteria through equivalent shell size, position count, fastening type, and operating temperature range. Both connectors are aluminum-bodied, bayonet-lock plugs with 16 positions and solder termination suitable for identical mechanical and electrical applications.

Engineering Selection Recommendations

Both connectors are active production parts with RoHS non-compliant status, consistent with military and aerospace applications. The PT06A20-16P-SR features gold mating contact finish with olive drab chromate over cadmium shell finish, while the MSW06A20-16P-SR uses cadmium finish on both shell and contacts. Selection between these parts should be based on:

Contact Finish Requirements: Gold contacts (PT06A20-16P-SR) provide enhanced corrosion resistance and lower contact resistance compared to cadmium contacts (MSW06A20-16P-SR)
Shell Finish Specifications: Olive drab chromate over cadmium (PT06A20-16P-SR) versus cadmium (MSW06A20-16P-SR) may be specified by application requirements
Inventory Availability: PT06A20-16P-SR has 883 units in stock; MSW06A20-16P-SR has 1036 units in stock
Electrical Ratings: MSW06A20-16P-SR provides specified current (13A) and voltage (800V) ratings; PT06A20-16P-SR ratings are not specified in available documentation

Frequently Asked Questions (FAQ)

Q: Can MSW06A20-16P-SR directly replace PT06A20-16P-SR in existing assemblies?

A: Yes, provided the application does not require gold contact finish or specific olive drab chromate shell finish. Both connectors share identical shell size (20-16), position count (16), fastening type (bayonet lock), termination method (solder), and operating temperature range (-55°C to 125°C).

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

A: PT06A20-16P-SR uses gold mating contact finish, which offers superior corrosion resistance and lower contact resistance. MSW06A20-16P-SR uses cadmium contact finish. Gold finish is preferred in high-reliability applications and corrosive environments.

Q: Are both connectors MIL-DTL-26482 compliant?

A: PT06A20-16P-SR is specified as MIL-DTL-26482 Series I, PT. MSW06A20-16P-SR is designated as 26482 Style Connectors. Verify specific compliance requirements with application documentation before substitution.

Q: What is the significance of the shell finish difference?

A: PT06A20-16P-SR features olive drab chromate over cadmium finish, standard for military aerospace applications. MSW06A20-16P-SR uses cadmium finish. Olive drab chromate provides additional corrosion protection and is specified in many military and aerospace standards.

Q: Are electrical ratings specified for both connectors?

A: MSW06A20-16P-SR provides current rating of 13A and voltage rating of 800V. PT06A20-16P-SR electrical ratings are not specified in available documentation. Consult manufacturer datasheets for complete electrical specifications when required.

Q: What is the moisture sensitivity level for these connectors?

A: PT06A20-16P-SR has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. MSW06A20-16P-SR MSL is listed as Not Applicable.
