CA20COM-L20-27P-B Equivalent & Substitute Parts

Part Overview

The CA20COM-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 inventory constraints, supply chain considerations, or specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CA20COM-L20-27P-B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle with male pins
• Position count: 14 positions
• Shell size designation: 20-27
• Series compliance: MIL-DTL-5015
• Operating temperature range: -55°C ~ 125°C
• Mounting configuration: Panel mount with flange

Secondary Compatibility Criteria:

• Contact material: Copper alloy
• Contact finish: Silver
• Shielding: Unshielded
• Primary material: Metal construction

The MS3102R-20-27P meets these primary and secondary criteria, establishing it as a valid substitute. Differences in termination method (solder cup versus solder), fastening type (threaded versus reverse bayonet lock), and shell finish do not preclude substitution when mechanical and electrical requirements are satisfied.

Engineering Selection Recommendations

CA20COM-L20-27P-B Selection Criteria:

Select the CA20COM-L20-27P-B when RoHS compliance is a mandatory requirement. This part maintains active production status and carries RoHS compliant certification. The reverse bayonet lock fastening provides positive mechanical engagement suitable for applications requiring frequent mating cycles. Nickel shell finish offers corrosion resistance in standard industrial environments. Solder termination with specified current and voltage ratings (22A, 50V) is documented.

MS3102R-20-27P Selection Criteria:

The MS3102R-20-27P is suitable for applications where RoHS compliance is not required and where military-grade specifications are the primary driver. This part is designated for marine and military applications. The threaded fastening type provides alternative mechanical engagement. Olive drab chromate over cadmium finish is specified for military environmental conditions. Solder cup termination accommodates different assembly processes. Current and voltage ratings are not specified for this part.

Compliance Considerations:

The CA20COM-L20-27P-B is the appropriate selection for applications subject to RoHS regulations or requiring documented compliance certification. The MS3102R-20-27P is affected by REACH regulations and carries RoHS non-compliant status, making it unsuitable for applications with regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MS3102R-20-27P directly replace CA20COM-L20-27P-B in all applications?

A: Direct replacement depends on application-specific requirements. Both parts share identical position count (14), shell size (20-27), operating temperature range (-55°C ~ 125°C), and MIL-DTL-5015 series compliance. However, differences in fastening type (threaded versus reverse bayonet lock), termination method (solder cup versus solder), and shell finish must be evaluated against specific mechanical and environmental requirements.

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

A: Solder termination on the CA20COM-L20-27P-B involves direct solder connection to contact pins. Solder cup termination on the MS3102R-20-27P features cup-shaped contact ends designed to accept wire leads for solder connection. The termination method affects assembly procedures and wire gauge compatibility.

Q: Are the fastening types interchangeable?

A: No. The CA20COM-L20-27P-B uses reverse bayonet lock fastening, while the MS3102R-20-27P uses threaded fastening. These are distinct mechanical interfaces. Mating connectors must be designed for the specific fastening type. Reverse bayonet lock provides quarter-turn engagement; threaded fastening requires rotational engagement.

Q: What is the significance of shell finish differences?

A: The CA20COM-L20-27P-B features nickel finish suitable for standard industrial and commercial environments. The MS3102R-20-27P features olive drab chromate over cadmium finish specified for military and marine environments. Shell finish affects corrosion resistance and environmental suitability. Selection depends on operating environment specifications.

Q: Does the current rating difference affect substitution?

A: The CA20COM-L20-27P-B specifies 22A current rating and 50V voltage rating. The MS3102R-20-27P does not provide specified current and voltage ratings. When electrical load requirements are defined, the CA20COM-L20-27P-B is the appropriate selection due to documented electrical specifications.

Q: What is the impact of RoHS compliance status?

A: The CA20COM-L20-27P-B is RoHS compliant; the MS3102R-20-27P is RoHS non-compliant. Applications subject to RoHS regulations, including consumer electronics, automotive, and many industrial applications in regulated markets, require RoHS compliant components. The CA20COM-L20-27P-B is mandatory for these applications.

Q: Are insert materials interchangeable?

A: The CA20COM-L20-27P-B uses polychloroprene insert material; the MS3102R-20-27P uses neoprene. Both materials provide electrical insulation and mechanical support. Material selection affects temperature stability and chemical resistance. Both materials support the specified operating temperature range (-55°C ~ 125°C).
