C&K U21SPYAQE Toggle Switch DPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K U21SPYAQE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch features an anti-rotation actuator, epoxy sealed terminals, and is designed for on-on switching applications. The part is active in production with RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting specifications, and functional circuit configuration. Alternative sources provide equivalent performance within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U21SPYAQE are qualified based on the following critical parameters:

• Electrical Equivalence: Identical DPDT circuit configuration with 5A current rating at 120V AC and 28V DC
• Mechanical Compatibility: Panel mount, right-angle orientation with matching 6.35mm circular panel cutout and 1/4-40 bushing thread
• Termination Compatibility: PC pin termination style for direct circuit board connection
• Environmental Specifications: Operating temperature range of -30°C to 85°C and MSL 1 rating
• Regulatory Compliance: RoHS3 compliance for hazardous substance restrictions

The E-Switch 100DP1T1B1M6QE and 100DP1T1B1M6QEH meet these substitution criteria. Both parts maintain identical electrical ratings, mechanical mounting specifications, and environmental operating parameters as the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - C&K U21SPYAQE: Select this part for applications requiring maximum electrical life specification (100,000 cycles) and when REACH-affected component documentation is acceptable. The anti-rotation actuator design provides additional mechanical stability in high-vibration environments.

Substitute Parts - E-Switch 100DP1T1B1M6QE and 100DP1T1B1M6QEH: Both E-Switch alternatives are suitable for applications where REACH compliance status is a procurement requirement. The REACH unaffected designation simplifies supply chain documentation. These parts maintain full electrical and mechanical compatibility with the primary part across all critical operating parameters.

All three parts maintain RoHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M6QE and 100DP1T1B1M6QEH be used interchangeably with C&K U21SPYAQE?

A: Yes. Both E-Switch parts are direct substitutes. They share identical electrical ratings (5A at 120V AC/28V DC), DPDT circuit configuration, panel mount specifications with 6.35mm circular cutout and 1/4-40 bushing thread, PC pin termination, and operating temperature range (-30°C to 85°C).

Q: What is the difference between the two E-Switch substitute parts?

A: The 100DP1T1B1M6QE and 100DP1T1B1M6QEH are electrically and mechanically identical. Both are manufactured by E-Switch with the same specifications. Packaging and inventory availability may differ between part numbers.

Q: Does the difference in electrical life (100,000 vs 40,000 cycles) affect substitution?

A: The E-Switch substitutes have lower electrical life ratings (40,000 cycles) compared to the C&K primary part (100,000 cycles). For applications requiring extended cycle life beyond 40,000 operations, the C&K U21SPYAQE is the appropriate selection.

Q: Are there mechanical compatibility concerns with the actuator length difference?

A: The C&K U21SPYAQE has an actuator length of 10.67mm with anti-rotation design, while E-Switch substitutes measure 10.41mm with standard round actuators. This 0.26mm difference is within typical mechanical tolerance for panel-mount toggle switches. Verify panel cutout depth and actuator engagement requirements for specific applications.

Q: What is the significance of REACH status in part selection?

A: REACH status indicates regulatory compliance for chemical substance restrictions in the European Union. The C&K part is REACH Affected, while E-Switch substitutes are REACH Unaffected. For supply chains requiring REACH unaffected components, E-Switch alternatives simplify procurement documentation.

Q: Are all three parts RoHS3 compliant?

A: Yes. The C&K U21SPYAQE and both E-Switch substitutes (100DP1T1B1M6QE and 100DP1T1B1M6QEH) are RoHS3 compliant, meeting hazardous substance restrictions for electronic components.
