CA02COM-L20-27P-B Equivalent & Substitute Parts

Part Overview

The CA02COM-L20-27P-B is a 14-position circular connector receptacle with male pins manufactured by ITT Cannon, LLC. This connector is designed for panel mount, through-hole applications with reverse bayonet lock fastening and solder termination. The part is currently active in production and maintains RoHS compliance status.

Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers. Substitution becomes necessary due to supply chain considerations, inventory availability, or specific application requirements while maintaining functional compatibility within the defined parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CA02COM-L20-27P-B are identified based on strict equivalence in the following critical parameters:

• Connector Type: Receptacle with male pins
• Position Count: 14 positions
• Shell Size: 20-27 insert designation
• Mounting Configuration: Panel mount with flange
• Electrical Ratings: Current and voltage capacity
• Temperature Range: Operating limits of -55°C to 125°C
• Series Compliance: MIL-DTL-5015 military standard

The MS3102R-20-27P from Amphenol Industrial Operations meets these core functional requirements. However, differences exist in termination method (solder cup versus solder), fastening type (threaded versus reverse bayonet lock), shell finish (olive drab chromate versus nickel), and regulatory compliance status. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

CA02COM-L20-27P-B Selection Criteria:

Select the CA02COM-L20-27P-B when the application requires RoHS compliance, reverse bayonet lock fastening, or nickel-plated shell finish. This part is suitable for applications where regulatory compliance with RoHS directives is mandatory. The reverse bayonet lock provides positive engagement without threaded fastening.

MS3102R-20-27P Selection Criteria:

The MS3102R-20-27P is suitable for military and marine applications where the olive drab chromate finish and threaded fastening are specified. This part is RoHS non-compliant and REACH-affected, making it unsuitable for applications with environmental compliance requirements. The solder cup termination differs from the solder termination of the main part and requires different PCB layout considerations.

Compatibility Constraints:

Both parts share the same 14-position, 20-27 shell size configuration and operate within identical temperature ranges. However, the differences in fastening type, termination method, and regulatory status mean these parts are not interchangeable without design modification. The choice between them depends on specific application requirements regarding compliance, fastening mechanism, and termination interface.

Frequently Asked Questions (FAQ)

Q: Can MS3102R-20-27P directly replace CA02COM-L20-27P-B in an existing design?

A: Direct replacement is not possible without design modification. The fastening types differ (threaded versus reverse bayonet lock), and the termination methods differ (solder cup versus solder). PCB layout and connector mounting hardware must be re-evaluated.

Q: What is the significance of the shell finish difference between these parts?

A: The CA02COM-L20-27P-B features a nickel finish, while the MS3102R-20-27P has an olive drab chromate over cadmium finish. These finishes provide different corrosion resistance properties and are selected based on environmental exposure and application requirements.

Q: Are both parts compliant with RoHS regulations?

A: No. The CA02COM-L20-27P-B is RoHS compliant. The MS3102R-20-27P is RoHS non-compliant and REACH-affected. Applications requiring environmental compliance must use the CA02COM-L20-27P-B.

Q: What is the difference between solder and solder cup termination?

A: Solder termination on the CA02COM-L20-27P-B involves direct solder connection to PCB pads. Solder cup termination on the MS3102R-20-27P uses a cup-shaped contact designed for wire insertion and solder filling. These require different PCB footprints and assembly processes.

Q: Do both connectors support the same current and voltage ratings?

A: The CA02COM-L20-27P-B specifies 22A at 50V. The MS3102R-20-27P does not provide current and voltage ratings in the available data. Electrical rating verification is required before substitution.

Q: What fastening mechanism does each connector use?

A: The CA02COM-L20-27P-B uses reverse bayonet lock fastening, which provides quick-connect capability without tools. The MS3102R-20-27P uses threaded fastening, requiring a mating connector with threaded coupling.

Q: Are both connectors suitable for the same temperature range?

A: Yes. Both connectors operate across the identical temperature range of -55°C to 125°C, making them thermally compatible for equivalent applications.
