U21P1CWCLE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The U21P1CWCLE is a panel-mount toggle switch manufactured by C&K, classified as DPDT (Double Pole Double Throw) with On-On switching function. This component is rated for 5A at 120V AC and 28V DC, featuring a flat anti-rotation actuator and IP67 ingress protection. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U21P1CWCLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Mechanical interface (Flat Anti-Rotation actuator, 21.33mm length, 6.35mm circular cutout, 1/4-40 bushing thread)
• Termination style (PC Pin)
• Environmental rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 cycles)

Parts meeting all these criteria are classified as direct substitutes within the C&K 7000 series.

Parameter Comparison

Engineering Selection Recommendations

The U21P1CWCRE serves as a direct functional substitute for the obsolete U21P1CWCLE. Both components are manufactured by C&K within the 7000 series and maintain identical electrical and mechanical specifications across all critical parameters.

The U21P1CWCRE is currently in active production status, ensuring availability for new designs and replacement applications. Both parts carry EAR99 export classification and meet environmental compliance standards. The U21P1CWCRE is RoHS Compliant and REACH Affected, while the original part is ROHS3 Compliant and REACH Unaffected. These compliance differences do not affect functional equivalence and should be evaluated based on end-application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the U21P1CWCRE directly replace the U21P1CWCLE in existing assemblies?

A: Yes. Both components share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT On-On), mechanical interface (panel mount with 6.35mm circular cutout, 1/4-40 bushing thread), and termination style (PC Pin). Physical dimensions and actuator specifications are equivalent.

Q: What is the primary difference between these two parts?

A: The U21P1CWCLE is obsolete, while the U21P1CWCRE is in active production. Compliance status differs: U21P1CWCRE is RoHS Compliant and REACH Affected, whereas U21P1CWCLE is ROHS3 Compliant and REACH Unaffected.

Q: Are there any environmental or operational limitations when substituting?

A: No. Both parts operate across the identical temperature range (-30°C to 85°C), maintain the same ingress protection rating (IP67), and deliver equivalent electrical life (100,000 cycles).

Q: How should compliance differences be handled in design documentation?

A: Compliance status should be verified against end-product regulatory requirements. The active production status of U21P1CWCRE ensures long-term availability and supply chain stability compared to the obsolete U21P1CWCLE.
