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

Part Overview

The C&K 7203SDCBE 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 PC pin termination and is designed for On-Off-On switching applications. The part is ROHS3 compliant and carries REACH Affected status. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple manufacturers, and maintain design compatibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203SDCBE is determined by strict alignment of the following critical parameters:

• Circuit configuration: DPDT only
• Switch function: On-Off-On operation
• Current and voltage ratings: 0.4VA at 20V AC/DC minimum
• Mounting type: Panel Mount with matching mechanical interface
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 85°C minimum
• Electrical life: 40,000 cycles minimum
• Regulatory compliance: ROHS3 Compliant

The E-Switch 100DP3T1B1M2REH qualifies as a direct substitute because it meets all critical electrical and mechanical parameters. Both parts share identical voltage/current ratings, circuit topology, mounting specifications, and environmental operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7203SDCBE and E-Switch 100DP3T1B1M2REH are active-status products with ROHS3 compliance. The E-Switch substitute offers the advantage of REACH Unaffected status, which may simplify regulatory documentation in certain supply chain scenarios. Both parts carry identical electrical ratings, circuit topology, and mechanical interface specifications. The actuator length difference (12.45mm versus 10.41mm) is a mechanical consideration that must be evaluated against specific panel design requirements and available mounting depth. Selection between these parts should be based on supply availability, lead time, and regulatory requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M2REH be used as a direct replacement for the C&K 7203SDCBE?

A: Yes, the E-Switch part qualifies as a direct electrical and mechanical substitute. Both parts share identical DPDT circuit configuration, On-Off-On switching function, 0.4VA/20V ratings, panel mount interface with 6.35mm circular cutout, 1/4-40 bushing thread, and PC pin termination. Verify that the 2.04mm actuator length difference accommodates your specific panel design.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by matching circuit configuration (DPDT), switch function (On-Off-On), current/voltage ratings (0.4VA/20V AC/DC), mounting type (Panel Mount), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), termination style (PC Pin), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles).

Q: Does the REACH status difference affect compatibility?

A: REACH status does not affect electrical or mechanical compatibility. The E-Switch part's REACH Unaffected status may reduce regulatory documentation requirements in certain jurisdictions, but this is a supply chain consideration rather than a functional one.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. Inventory availability differs: C&K 7203SDCBE has 900 pieces in stock, while E-Switch 100DP3T1B1M2REH has 1401 pieces available.

Q: What should be verified before implementing a substitution?

A: Confirm that the 10.41mm actuator length of the E-Switch part provides adequate clearance within your panel assembly. Verify that both parts meet your specific application's environmental and electrical requirements within the stated -30°C to 85°C operating range and 40,000-cycle electrical life specification.
