U23P4HCQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The U23P4HCQE is an active production toggle switch manufactured by C&K, classified as a DPDT (Double Pole Double Throw) panel mount switch rated for 5A at 120V AC and 28V DC. This switch features a flat anti-rotation actuator with a 6.35mm length, non-illuminated design, and epoxy sealed PC pin terminals. The product is in active status with 634 units currently in stock.

Alternative equivalent parts may be required due to supply chain constraints, packaging preferences, or inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U23P4HCQE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 Cycles)

The substitute part 100DP3T1B9M2QEH manufactured by E-Switch meets all critical electrical and mechanical parameters required for direct substitution. Variations in actuator type (Standard Round vs. Flat Anti-Rotation) and actuator length (10.41mm vs. 6.35mm) do not affect electrical performance or panel mounting compatibility, as the panel cutout and bushing thread specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the U23P4HCQE and 100DP3T1B9M2QEH are active production components with ROHS3 compliance. The U23P4HCQE carries REACH Affected status, while the 100DP3T1B9M2QEH is REACH Unaffected. Both components are classified under ECCN EAR99 and share identical HTSUS coding (8536.50.9065).

Selection between these parts should be based on:

• Supply availability and lead time requirements
• Packaging format preference (Tray vs. Bulk)
• Actuator design requirements (Flat Anti-Rotation vs. Standard Round)
• REACH compliance obligations for the end application
• Current inventory levels (634 units for U23P4HCQE; 960 units for 100DP3T1B9M2QEH)

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T1B9M2QEH replace the U23P4HCQE in existing designs?

A: Yes. Both switches share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), and mechanical mounting specifications (6.35mm panel cutout, 1/4-40 bushing thread). The difference in actuator length does not affect panel mounting compatibility.

Q: What is the significance of the actuator type difference?

A: The U23P4HCQE features a flat anti-rotation actuator, while the 100DP3T1B9M2QEH uses a standard round actuator. This affects only the tactile feel and rotational resistance of the switch lever. Electrical performance and panel integration remain unchanged.

Q: Are there REACH compliance differences between these parts?

A: Yes. The U23P4HCQE is REACH Affected, while the 100DP3T1B9M2QEH is REACH Unaffected. Applications subject to REACH regulations should verify compliance requirements with their supply chain.

Q: What packaging formats are available?

A: The U23P4HCQE is supplied in Tray packaging, while the 100DP3T1B9M2QEH is supplied in Bulk packaging. Packaging selection may impact handling, storage, and integration into assembly processes.

Q: Do both parts meet the same environmental specifications?

A: Yes. Both switches operate across the identical temperature range (-30°C to 85°C) and maintain 40,000 electrical life cycles under rated conditions.
