U23P3HCQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The U23P3HCQE is an active production toggle switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) circuitry with On-Off-On switching function. This panel-mount component is rated for 5A at 120V AC and 28V DC, with a flat anti-rotation actuator and PC pin termination. The component is stocked at 772 units in new original condition. Substitute parts are identified when equivalent electrical ratings, mechanical interfaces, and functional characteristics align within acceptable parameters for the application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U23P3HCQE is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Panel cutout diameter: 6.35mm (Circular)
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 Cycles

Electrical Rating Compatibility: Substitute parts must support the application's voltage and current requirements. The U23P3HCQE operates at 5A (AC/DC), 120V AC, and 28V DC. Substitute components with lower electrical ratings are not suitable for direct replacement in applications requiring the full rated capacity.

The identified substitute part 100DP3T1B1M2REH (E-Switch, Series 100) shares the mechanical interface specifications and functional characteristics but operates at reduced electrical ratings (0.4VA, 20V AC/DC). This part is suitable only for applications with lower power requirements than the original specification.

Parameter Comparison

Engineering Selection Recommendations

U23P3HCQE (Primary Component): The U23P3HCQE maintains active production status with ROHS3 compliance and REACH affected designation. This component is suitable for applications requiring 5A switching capacity at 120V AC or 28V DC with DPDT On-Off-On functionality. The flat anti-rotation actuator provides mechanical stability in panel-mount installations.

100DP3T1B1M2REH (Substitute Component): The 100DP3T1B1M2REH is an active production alternative from E-Switch with identical mechanical interfaces and functional switching characteristics. This component maintains ROHS3 compliance and REACH unaffected status. However, the reduced electrical rating (0.4VA, 20V AC/DC) restricts its application to low-power circuits. Selection of this substitute requires confirmation that the application's actual power requirements do not exceed the component's rated capacity. The standard round actuator differs from the flat anti-rotation design of the primary component.

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T1B1M2REH directly replace the U23P3HCQE in all applications?

A: No. While both components share identical panel cutout dimensions (6.35mm), bushing thread (1/4-40), and termination style (PC Pin), the 100DP3T1B1M2REH has significantly lower electrical ratings (0.4VA, 20V AC/DC versus 5A, 120V AC/28V DC). Direct substitution is only valid for applications with power requirements below the substitute component's rated capacity.

Q: What are the mechanical interface differences between these components?

A: Both components feature circular panel cutouts of 6.35mm diameter and 1/4-40 bushing threads, ensuring compatible panel mounting. The primary difference is the actuator design: the U23P3HCQE uses a flat anti-rotation actuator (11.43mm length), while the 100DP3T1B1M2REH uses a standard round actuator (10.41mm length). This affects operator feel and mechanical stability but does not prevent physical installation.

Q: Are both components RoHS compliant?

A: Yes. Both the U23P3HCQE and 100DP3T1B1M2REH are ROHS3 compliant. However, the U23P3HCQE is REACH affected, while the 100DP3T1B1M2REH is REACH unaffected. Regulatory requirements for your application may influence component selection.

Q: What is the electrical life expectancy for both components?

A: Both components are rated for 40,000 electrical cycles, providing equivalent operational longevity under their respective electrical ratings.

Q: How do the operating temperature ranges compare?

A: Both components operate across the identical temperature range of -30°C to 85°C, ensuring thermal compatibility in equivalent environmental conditions.
