Equivalent & Substitute Parts for U23P3DCQE

Part Overview

The U23P3DCQE is a toggle switch manufactured by C&K, classified as a DPDT (Double Pole Double Throw) panel mount switch with On-Off-On functionality. This switch is rated for 5A at 120V AC and 28V DC, featuring a flat anti-rotation actuator and PC pin termination. The product is currently active and available in inventory with 613 units in stock.

Finding equivalent and substitute parts is necessary when the primary component becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits operation within a broader range of electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U23P3DCQE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C or broader

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed the application requirement
• Voltage rating (AC/DC): Substitute must meet or exceed the application requirement
• Actuator type and length: May vary if mechanical clearance permits
• Electrical life: May vary based on application cycle requirements

The substitute part 100DP3T1B1M2REH from E-Switch shares the same circuit configuration, switch function, mounting type, panel cutout dimensions, bushing thread, termination style, and operating temperature range. However, it operates at reduced current and voltage ratings, making it suitable only for applications with lower electrical demands.

Parameter Comparison

Engineering Selection Recommendations

The U23P3DCQE remains the primary selection for applications requiring 5A at 120V AC or 28V DC operation. This part is active, ROHS3 compliant, and maintains full inventory availability.

The 100DP3T1B1M2REH from E-Switch is a valid substitute only for applications with electrical requirements not exceeding 0.4VA at 20V AC/DC. This substitute shares identical mechanical and functional characteristics but operates at significantly reduced current and voltage ratings. Selection of this substitute requires confirmation that the application does not exceed these electrical limits.

Both parts maintain ROHS3 compliance and identical operating temperature ranges, supporting long-term supply chain flexibility within their respective electrical operating envelopes.

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T1B1M2REH replace the U23P3DCQE in all applications?

A: No. The 100DP3T1B1M2REH is rated for 0.4VA at 20V maximum, while the U23P3DCQE is rated for 5A at 120V AC or 28V DC. Substitution is valid only when the application electrical requirements do not exceed the lower ratings of the E-Switch part.

Q: Are the mechanical interfaces identical between these parts?

A: Yes. Both parts share identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. Panel mounting and mechanical installation are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the U23P3DCQE and 100DP3T1B1M2REH are ROHS3 compliant and operate across the identical temperature range of -30°C to 85°C.

Q: What is the primary difference between these parts?

A: The primary difference is electrical rating. The U23P3DCQE supports higher current (5A) and voltage (120V AC, 28V DC), while the 100DP3T1B1M2REH is limited to 0.4VA at 20V. Both maintain identical DPDT On-Off-On functionality and mechanical form factor.

Q: Which part should be selected for new designs?

A: Select based on application electrical requirements. If the application requires 5A at 120V AC or 28V DC, the U23P3DCQE is the appropriate choice. If the application operates at 20V or below with current not exceeding 0.4VA, either part may be used, with the 100DP3T1B1M2REH offering an alternative sourcing option.
