7203SHCGES Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The 7203SHCGES is an active production toggle switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) circuitry with On-Off-On switching function. This panel-mount component is rated for 5A at 120V AC and 28V DC, with a satin chrome actuator and PC pin termination. The part is in active product status with 1098 units currently in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203SHCGES is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Termination style must be PC Pin
• Operating temperature range must be -30°C ~ 85°C
• Electrical life must be 40,000 Cycles
• RoHS3 compliance required

The identified substitute part 100DP3T1B1M2REH from E-Switch meets all mechanical and environmental specifications. However, electrical ratings differ: the substitute is rated for 0.4VA at 20V (AC/DC), compared to the main part's 5A at 120V AC and 28V DC. This substitute is suitable only for applications operating within the lower voltage and current envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 7203SHCGES and 100DP3T1B1M2REH are active production components with ROHS3 compliance and identical mechanical specifications. Selection between these parts is determined by application voltage and current requirements.

The 7203SHCGES is specified for applications requiring 120V AC or 28V DC operation at 5A current capacity. The 100DP3T1B1M2REH is specified for applications operating at 20V AC/DC with 0.4VA capacity. Direct substitution of the E-Switch part for the C&K part is valid only when the application circuit operates within the lower electrical envelope. Reverse substitution (using 7203SHCGES where 100DP3T1B1M2REH is specified) is not recommended due to potential overstress of the lower-rated component.

Both parts carry identical certifications and environmental ratings, supporting interchangeability within their respective electrical operating ranges.

Frequently Asked Questions (FAQ)

Q: Can 100DP3T1B1M2REH replace 7203SHCGES in all applications?

A: No. The 100DP3T1B1M2REH is rated for 0.4VA at 20V maximum, while the 7203SHCGES is rated for 5A at 120V AC. Substitution is valid only for applications operating within the lower electrical specifications.

Q: Are the mechanical dimensions identical between these parts?

A: The panel cutout (6.35mm circular), bushing thread (1/4-40), and termination style (PC Pin) are identical. Actuator length differs slightly: 10.67mm for 7203SHCGES versus 10.41mm for 100DP3T1B1M2REH. This minor difference does not affect panel mounting compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and rated for -30°C to 85°C operating temperature with 40,000 electrical life cycles.

Q: What is the key difference between these toggle switches?

A: The primary difference is electrical rating. The 7203SHCGES supports higher voltage (120V AC) and current (5A), while the 100DP3T1B1M2REH is designed for lower-power applications (20V, 0.4VA). Both share identical DPDT On-Off-On switching function and panel-mount configuration.

Q: Can I use 7203SHCGES where 100DP3T1B1M2REH is specified?

A: This is not recommended. Using a higher-rated component in a circuit designed for lower ratings may introduce reliability or safety concerns specific to the application design.
