C&K 7403SPYZGE Toggle Switch 4PDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7403SPYZGE is a panel-mount toggle switch with 4PDT (four-pole double-throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch operates in an On-Off-On function with anti-rotation actuator design and epoxy-sealed solder lug terminals. The product is active and ROHS3 compliant. Equivalent and substitute parts are identified when they maintain identical electrical ratings, circuit configuration, mounting specifications, and termination style while meeting the same compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403SPYZGE are identified based on strict equivalence across the following critical parameters:

• Circuit configuration: 4PDT
• Switch function: On-Off-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature: -30°C ~ 85°C
• Electrical life: 40,000 Cycles
• Features: Epoxy Sealed Terminals
• RoHS compliance: ROHS3 Compliant

The E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all these criteria. Minor variations in actuator type (anti-rotation versus standard round) and actuator length (10.67mm versus 10.41mm) do not affect electrical or mechanical compatibility for panel-mount applications with identical cutout and bushing specifications.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are functionally equivalent to the C&K 7403SPYZGE for applications requiring 4PDT toggle switches with 5A/120V AC ratings and panel-mount configuration. All three parts maintain ROHS3 compliance and active product status.

The 1004P3T1B1M1QEH variant offers higher inventory availability (1991 pcs) compared to the 1004P3T1B1M1QE (764 pcs) and the original C&K part (689 pcs). Selection between these substitutes should be based on supply chain requirements and lead time considerations, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QE directly replace the C&K 7403SPYZGE?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (4PDT), mounting specifications (panel mount, 6.35mm circular cutout, 1/4-40 bushing thread), and termination style (solder lug). The minor difference in actuator type does not affect compatibility in panel-mount applications.

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

A: The 1004P3T1B1M1QE and 1004P3T1B1M1QEH are electrically and mechanically identical. The primary distinction is inventory availability, with the QEH variant offering significantly higher stock levels.

Q: Are all three parts ROHS3 compliant?

A: Yes. The C&K 7403SPYZGE and both E-Switch substitutes (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are ROHS3 compliant.

Q: Do the actuator length differences affect panel mounting?

A: No. The actuator length variation (10.67mm for C&K versus 10.41mm for E-Switch) does not impact panel cutout compatibility or bushing thread engagement, as both maintain the same 6.35mm circular cutout and 1/4-40 bushing thread specifications.

Q: What is the electrical life rating for these switches?

A: All three parts are rated for 40,000 electrical cycles, ensuring consistent operational durability across the main part and substitutes.
