C&K 7203SY4ZGE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203SY4ZGE is an active production toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with solder lug termination and is designed for On-Off-On switching applications. The part is ROHS3 compliant and maintains an operating temperature range of -30°C to 85°C with 40,000 electrical life cycles. Equivalent substitute parts are identified based on matching electrical ratings, mechanical dimensions, circuit configuration, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7203SY4ZGE are identified based on strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A at 120V AC / 28V DC)
• Mounting type (Panel Mount)
• Actuator type (Standard Round)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Termination style (Solder Lug)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 Cycles)
• RoHS compliance status (ROHS3 Compliant)

The E-Switch 100DP3T1B1M1QEH meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7203SY4ZGE and E-Switch 100DP3T1B1M1QEH are active production components with ROHS3 compliance. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain preferences and established vendor relationships
• Minor actuator length variance (10.67mm vs 10.41mm), which may affect panel aesthetics but does not impact electrical function
• REACH compliance status: The C&K part is REACH Affected, while the E-Switch part is REACH Unaffected

For applications requiring REACH compliance documentation, the E-Switch 100DP3T1B1M1QEH is the appropriate selection. Both parts are electrically and mechanically equivalent for standard DPDT switching applications within the specified ratings.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M1QEH be used as a direct replacement for the C&K 7203SY4ZGE?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (DPDT), mounting specifications (Panel Mount with 1/4-40 bushing thread), and panel cutout dimensions (6.35mm circular). Both are ROHS3 compliant and rated for 40,000 electrical cycles across the same operating temperature range.

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

A: The actuator length variance (10.67mm vs 10.41mm) is 0.26mm. This minor difference does not affect electrical performance or mechanical compatibility with standard panel cutouts. Visual appearance and tactile feel may differ slightly, but functional operation remains identical.

Q: Does REACH compliance status affect substitution eligibility?

A: REACH compliance status is a regulatory consideration specific to supply chain and end-market requirements. The C&K 7203SY4ZGE is REACH Affected, while the E-Switch 100DP3T1B1M1QEH is REACH Unaffected. Selection should align with applicable regulatory requirements for your application region and end-use market.

Q: Are both parts suitable for solder lug termination in PCB assembly?

A: Yes. Both parts feature solder lug termination and are designed for direct soldering to circuit boards or wiring harnesses. No adapter or modification is required for electrical connection.

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

A: Both the C&K 7203SY4ZGE and E-Switch 100DP3T1B1M1QEH are rated for 40,000 electrical cycles, representing the number of complete on-off switching operations under rated load conditions.
