Toggle Switch DPDT 7203P3HCGE Equivalent & Substitute Parts

Part Overview

The 7203P3HCGE 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 switch is rated for 5A at 120V AC and 28V DC, with a flat anti-rotation actuator and PC pin termination. The component is designed for applications requiring reliable switching with epoxy sealed terminals and operates across a temperature range of -30°C to 85°C. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional characteristics align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203P3HCGE is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Current rating must support the application load
• Voltage ratings must meet or exceed the original specification

Mechanical Compatibility Requirements:

• 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

Environmental & Operational Requirements:

• Operating temperature range must encompass -30°C to 85°C
• Electrical life must be 40,000 cycles or greater

The substitute part 100DP3T1B1M2REH from E-Switch shares the same circuit configuration (DPDT), switch function (On-Off-On), mechanical mounting specifications, and environmental operating parameters. However, the substitute part has reduced electrical ratings (0.4VA at 20V AC/DC versus 5A at 120V AC and 28V DC), which restricts its application to lower-power circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the 7203P3HCGE and 100DP3T1B1M2REH are active production components with ROHS3 compliance and equivalent mechanical mounting specifications. Selection between these parts must be based on electrical load requirements:

The 7203P3HCGE is suitable for applications requiring 5A switching capacity at 120V AC or 28V DC. The 100DP3T1B1M2REH is limited to 0.4VA at 20V AC/DC, making it appropriate only for low-power signal switching applications. Direct substitution of the E-Switch part for the C&K part is not permissible in circuits designed for the higher current and voltage ratings of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T1B1M2REH replace the 7203P3HCGE in all applications?

A: No. While both parts share identical mechanical mounting specifications and circuit configuration, the 100DP3T1B1M2REH has significantly lower electrical ratings (0.4VA at 20V versus 5A at 120V AC). Substitution is only valid for applications with electrical loads within the E-Switch part's rating limits.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both parts require a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread, ensuring mechanical interchangeability at the panel interface level.

Q: Do both parts meet the same environmental operating specifications?

A: Yes. Both the 7203P3HCGE and 100DP3T1B1M2REH operate across the -30°C to 85°C temperature range and maintain 40,000 electrical life cycles.

Q: What is the primary limitation of the E-Switch substitute part?

A: The 100DP3T1B1M2REH is rated for 0.4VA at 20V AC/DC, compared to the C&K part's 5A at 120V AC and 28V DC. This makes it unsuitable for higher-power switching applications.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 7203P3HCGE and 100DP3T1B1M2REH are ROHS3 compliant and suitable for applications with RoHS requirements.
