C&K 7203SY4ZBE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203SY4ZBE is an active-status toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a standard round actuator with solder lug termination and is designed for On-Off-On switching applications. The product is ROHS3 compliant and REACH affected. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit configuration align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7203SY4ZBE is determined by the following critical parameters:

• Circuit Configuration: DPDT (Double Pole Double Throw) is mandatory
• Switch Function: On-Off-On operation required
• Mounting Type: Panel Mount with circular 6.35mm diameter cutout and 1/4-40 bushing thread
• Termination Style: Solder Lug
• Actuator Type: Standard Round
• Operating Temperature Range: -30°C ~ 85°C minimum
• Electrical Life: 40,000 cycles minimum
• Compliance: ROHS3 compliant

The E-Switch 100DP3T1B1M1QEH qualifies as a substitute because it maintains identical circuit configuration (DPDT), switch function (On-Off-On), mounting specifications (panel mount with matching cutout and bushing thread), termination style (solder lug), actuator type (standard round), operating temperature range (-30°C ~ 85°C), electrical life (40,000 cycles), and ROHS3 compliance. The substitute part exceeds the voltage and current ratings of the main part, making it suitable for applications requiring higher electrical performance within the same mechanical and functional envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7203SY4ZBE and E-Switch 100DP3T1B1M1QEH are active-status products with ROHS3 compliance. The E-Switch 100DP3T1B1M1QEH is REACH unaffected, whereas the C&K part is REACH affected. Selection between these parts should be based on regulatory requirements specific to the end application and supply chain constraints. The E-Switch substitute provides higher electrical ratings (5A at 120V AC / 28V DC) compared to the C&K main part (0.4VA at 20V AC/DC), making it suitable for applications requiring greater electrical capacity while maintaining identical mechanical and functional specifications. Both parts share the same panel cutout dimensions, bushing thread specification, and termination style, ensuring direct mechanical compatibility in panel-mount installations.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M1QEH directly replace the C&K 7203SY4ZBE in existing designs?

A: Yes, provided the application circuit operates within the electrical specifications of the substitute part. The E-Switch part maintains identical DPDT circuit configuration, On-Off-On switch function, panel mount dimensions (6.35mm circular cutout with 1/4-40 bushing thread), solder lug termination, and operating temperature range (-30°C ~ 85°C). The higher current and voltage ratings of the substitute part do not prevent direct replacement in lower-power applications.

Q: What are the key mechanical compatibility factors?

A: Panel cutout diameter (6.35mm circular), bushing thread specification (1/4-40), actuator type (standard round), and termination style (solder lug) must match between the main part and substitute. Both parts in this comparison meet these requirements. Actuator length differs slightly (10.67mm vs. 10.41mm), which is within acceptable tolerance for standard panel-mount toggle switch applications.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and rated for -30°C to 85°C operation. The C&K 7203SY4ZBE is REACH affected, while the E-Switch 100DP3T1B1M1QEH is REACH unaffected. Applications subject to REACH regulations should verify compliance requirements before selecting the substitute part.

Q: What electrical performance difference exists between these parts?

A: The C&K 7203SY4ZBE is rated for 0.4VA at 20V AC/DC. The E-Switch 100DP3T1B1M1QEH is rated for 5A at 120V AC and 28V DC. The substitute part provides significantly higher electrical capacity and is suitable for applications requiring greater power handling while maintaining the same circuit topology and mechanical form factor.

Q: Are both parts available in bulk packaging?

A: Yes. The C&K 7203SY4ZBE has 818 pieces in stock (bulk packaging), and the E-Switch 100DP3T1B1M1QEH has 1,327 pieces in stock (bulk packaging).
