C&K 7403SH3ZGE Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7403SH3ZGE is a panel-mount toggle switch with 4PDT (four-pole double-throw) configuration rated for 5A at 120V AC and 28V DC. This switch features an On-Off-On function with solder lug termination and epoxy sealed terminals. The product is active and in stock with 867 units available. Equivalent and substitute parts are identified when they maintain identical electrical ratings, mechanical compatibility, and functional specifications across the critical parameters that define interchangeability for this switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403SH3ZGE are qualified based on strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A at 120V AC / 28V DC)
• Mounting type and panel cutout dimensions (Panel Mount, Circular 6.35mm Dia, 1/4-40 bushing thread)
• Termination style (Solder Lug)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 cycles)

The E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all these criteria and are therefore direct substitutes. Both parts maintain identical electrical specifications, mechanical compatibility, and functional performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—C&K 7403SH3ZGE, E-Switch 1004P3T1B1M1QE, and E-Switch 1004P3T1B1M1QEH—are active products with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Compliance status: The C&K 7403SH3ZGE is REACH Affected, while both E-Switch alternatives are REACH Unaffected
• Application-specific supply chain or qualification requirements

The E-Switch 1004P3T1B1M1QEH offers the highest inventory level at 1991 units, providing supply chain flexibility for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH be used interchangeably with C&K 7403SH3ZGE?

A: Yes. Both E-Switch parts are direct substitutes. They maintain identical circuit configuration (4PDT), electrical ratings (5A at 120V AC / 28V DC), mechanical dimensions, termination style, and operating temperature range. Panel cutout and bushing thread specifications are identical, ensuring mechanical compatibility.

Q: What is the difference between E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: 1004P3T1B1M1QEH has 1991 units in stock compared to 764 units for 1004P3T1B1M1QE. Both are REACH Unaffected, whereas the C&K part is REACH Affected.

Q: Are there any actuator length differences between these parts?

A: The C&K 7403SH3ZGE has an actuator length of 10.16mm, while both E-Switch substitutes have 10.41mm. This 0.25mm difference does not affect functional compatibility or panel mounting, as both dimensions fall within standard panel-mount switch specifications.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, carry MSL Rating 1 (Unlimited), and share the same ECCN (EAR99) and HTSUS code (8536.50.9065). The key compliance difference is REACH status: C&K 7403SH3ZGE is REACH Affected, while both E-Switch alternatives are REACH Unaffected.

Q: Can these switches be used in applications requiring REACH compliance?

A: Applications requiring REACH Unaffected components should use E-Switch 1004P3T1B1M1QE or 1004P3T1B1M1QEH. The C&K 7403SH3ZGE is REACH Affected and may require additional compliance documentation depending on application and regional requirements.
