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

Part Overview

The C&K 7203SPDZBE 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 anti-rotation actuator design with epoxy-sealed solder lug termination, suitable for applications requiring reliable on-off-on switching functionality. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative component selection.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C ~ 85°C minimum

Allowable Parameter Variations:

• Current rating: Substitute must equal or exceed 0.4VA
• Voltage rating (AC): Substitute must equal or exceed 20V
• Voltage rating (DC): Substitute must equal or exceed 20V
• Actuator type: May differ (anti-rotation vs. standard round)
• Actuator length: May vary within mechanical constraints
• Electrical life: May exceed 40,000 cycles
• RoHS and REACH compliance: Must maintain or improve regulatory status

The E-Switch 100DP3T1B1M1QEH qualifies as a substitute based on these criteria, offering higher current and voltage ratings while maintaining identical mechanical and functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7203SPDZBE and E-Switch 100DP3T1B1M1QEH maintain active product status and ROHS3 compliance. The E-Switch substitute provides superior electrical performance with 5A current capacity and 120V AC rating, compared to the primary part's 0.4VA and 20V specifications. Both components share identical mechanical interfaces (panel cutout, bushing thread, termination style) and operating temperature range, ensuring direct mechanical compatibility in panel-mount applications.

Selection between these parts should be based on application electrical requirements. The C&K 7203SPDZBE is appropriate for low-power signal switching applications. The E-Switch 100DP3T1B1M1QEH is suitable for higher-power applications requiring greater current and voltage capacity while maintaining the same mechanical form factor.

Frequently Asked Questions (FAQ)

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

A: Mechanical compatibility is confirmed. Both switches share identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and solder lug termination. The E-Switch substitute has a shorter actuator length (10.41mm vs. 12.45mm), which may affect panel clearance in space-constrained applications. Electrical compatibility depends on circuit design; the higher ratings of the E-Switch substitute do not create incompatibility with lower-power circuits.

Q: What are the key differences between these DPDT toggle switches?

A: The primary differences are current and voltage ratings. The C&K 7203SPDZBE is rated for 0.4VA at 20V, while the E-Switch 100DP3T1B1M1QEH is rated for 5A at 120V AC and 28V DC. Actuator design differs (anti-rotation vs. standard round), and actuator length varies by approximately 2mm. Both maintain identical circuit function (DPDT On-Off-On), operating temperature range, and electrical life specifications.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and maintain active product status. The C&K part is REACH Affected, while the E-Switch substitute is REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What applications are suitable for each part?

A: The C&K 7203SPDZBE is designed for low-power signal switching applications operating at 20V or below. The E-Switch 100DP3T1B1M1QEH accommodates higher-power applications requiring up to 5A at 120V AC or 28V DC, while maintaining the same mechanical interface and on-off-on switching function.
