Engineering Selection Recommendations
Both PT00A20-16S-SR and MSW00A20-16S-SR are active products with RoHS non-compliant status, indicating continued availability and military-grade specifications. Selection between these parts should be based on the following provided parameters:
PT00A20-16S-SR is the primary specification with gold contact finish mating surfaces and olive drab chromate over cadmium shell finish, providing enhanced corrosion resistance and contact reliability for demanding aerospace and communication applications.
MSW00A20-16S-SR provides an equivalent mechanical and electrical interface with cadmium shell and contact finishes, and includes specified current (13A) and voltage (800V) ratings. This substitute maintains MIL-DTL-26482 compliance and is suitable for applications where the specified electrical ratings are acceptable.
The primary distinction between these parts lies in surface finish specifications. The main part's gold contact finish and chromate treatment provide superior corrosion protection, while the substitute's cadmium finish offers a cost-effective alternative where environmental exposure is controlled. Both parts support identical mechanical interfaces and operating temperature ranges.
Frequently Asked Questions (FAQ)
Q: Can MSW00A20-16S-SR be used as a direct replacement for PT00A20-16S-SR?
A: MSW00A20-16S-SR meets the core mechanical and electrical interface requirements for substitution. Both connectors feature 16 positions, 20-16 shell sizing, panel mount flange configuration, bayonet lock fastening, and -55°C to 125°C operating temperature range. The primary difference is surface finish specification: the main part features gold contact finish and olive drab chromate over cadmium shell finish, while the substitute features cadmium finishes. Substitution is valid where these finish specifications are acceptable for the application.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution eligibility is determined by equivalence in connector type (receptacle, female sockets), position count (16), shell size (20-16), mounting configuration (panel mount flange), fastening method (bayonet lock), termination capability (solder), shell material (aluminum), and operating temperature range (-55°C to 125°C). All these parameters are identical between the main part and substitute.
Q: Are there differences in packaging between these parts?
A: The main part PT00A20-16S-SR packaging is not specified in the provided data. The substitute MSW00A20-16S-SR is packaged in bags. Packaging differences do not affect electrical or mechanical compatibility.
Q: Do both parts meet military specifications?
A: Both PT00A20-16S-SR and MSW00A20-16S-SR conform to MIL-DTL-26482 specifications. Both are classified as RoHS non-compliant, consistent with military-grade connector standards. Both maintain active product status.
Q: What is the significance of the contact finish difference?
A: The main part features gold contact finish on mating surfaces, providing superior corrosion resistance and contact reliability. The substitute features cadmium contact finish. Gold plating is typically specified for high-reliability aerospace and communication applications where contact resistance stability is critical. Cadmium finish is acceptable for applications where environmental exposure is controlled and cost optimization is a priority.
Q: What is the significance of the shell finish difference?
A: The main part features olive drab chromate over cadmium shell finish, providing enhanced corrosion protection through chromate conversion coating. The substitute features cadmium finish only. Chromate treatment provides superior protection in harsh environmental conditions. Selection should be based on the specific environmental exposure requirements of the application.
