Substitute Part Grouping Explanation

The PL455ACPS-201 qualifies as a parametric equivalent to the PL455ACPP-201 based on matching electrical and mechanical specifications. Both parts share identical connector style (1553 twinaxial), connector type (plug with male pin and female socket concentric configuration), termination methods (crimp for both contact and shield), mounting characteristics (free hanging in-line), fastening mechanism (bayonet lock), and all critical electrical parameters including frequency rating (2 MHz maximum), voltage rating (900 V), and operating temperature range (-65°C to 125°C).

Material specifications are identical: beryllium copper center contacts with gold plating, brass body with nickel finish. Both parts maintain the same series designation (450), cable group compatibility (M17/176-00002), and regulatory compliance (RoHS compliant, MSL 1 unlimited). The substitution is valid based on these matching parameters, with the primary distinction being the package contents included with each part number.

Engineering Selection Recommendations

Both PL455ACPP-201 and PL455ACPS-201 are active production parts with identical RoHS compliance and regulatory certifications (ECCN: EAR99, HTSUS: 8536.69.4010). Selection between these parts should be based on assembly requirements and package contents. The PL455ACPP-201 includes a connector and heat shrink, while the PL455ACPS-201 includes a connector, bushing, and heat shrink. Choose the part number that matches your system's mechanical assembly needs. Both parts are electrically and mechanically interchangeable for applications requiring 1553 twinaxial connectors with crimp termination, bayonet fastening, and operation within the specified frequency, voltage, and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Are PL455ACPP-201 and PL455ACPS-201 electrically interchangeable?

A: Yes. Both parts have identical electrical specifications including 2 MHz maximum frequency, 900 V voltage rating, and -65°C to 125°C operating temperature range. They share the same connector style, contact materials, and termination methods.

Q: What is the difference between these two part numbers?

A: The primary difference is package contents. PL455ACPP-201 includes 1 connector and 1 heat shrink. PL455ACPS-201 includes 1 connector, 1 bushing, and 1 heat shrink. The connector itself is mechanically and electrically identical.

Q: Can I use PL455ACPS-201 as a direct replacement for PL455ACPP-201?

A: Yes, for applications where the connector specifications match your requirements. Verify that the additional bushing included with PL455ACPS-201 does not conflict with your assembly design.

Q: Are both parts RoHS compliant?

A: Yes. Both PL455ACPP-201 and PL455ACPS-201 are RoHS compliant with MSL 1 (unlimited) moisture sensitivity level.

Q: What cable group are these connectors compatible with?

A: Both parts are compatible with cable group M17/176-00002 per the 1553 twinaxial connector standard.

Q: Do these connectors support the same mating cycles and insertion loss specifications?

A: The provided specifications do not include mating cycle or insertion loss data for either part number. Consult the manufacturer's detailed technical documentation for these parameters if required for your application.
