Toggle Switch DPDT 7203MH3CGE Equivalent & Substitute Parts

Part Overview

The 7203MH3CGE is a panel-mounted toggle switch manufactured by C&K, classified as DPDT (Double Pole Double Throw) with On-Off-On switching function. This component operates at 5A AC/DC with voltage ratings of 120V AC and 28V DC. The switch features epoxy sealed terminals, non-illuminated design, and PC pin termination suitable for industrial control and instrumentation applications. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the 7203MH3CGE remains in production. Equivalent parts are identified to support supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203MH3CGE is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Current rating must be 5A (AC/DC)
• Voltage ratings must be 120V AC and 28V DC minimum
• Mounting type must be Panel Mount
• Termination style must be PC Pin
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Operating temperature range must encompass -30°C ~ 85°C
• Electrical life must be 40,000 cycles minimum

The substitute part 100DP3T1B9M2QEH (E-Switch) meets all mandatory electrical and mechanical parameters. Variations in actuator length (4.57mm vs. 10.41mm) do not affect functional substitution when panel mounting geometry and cutout specifications remain identical. Both parts maintain identical circuit behavior, load capacity, and environmental performance within specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the 7203MH3CGE and 100DP3T1B9M2QEH are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Procurement cost and inventory positioning
• Actuator length compatibility with panel design (4.57mm vs. 10.41mm)
• Manufacturer preference or qualification requirements
• REACH compliance status (7203MH3CGE is REACH Affected; 100DP3T1B9M2QEH is REACH Unaffected)

Both components satisfy identical functional requirements for DPDT 5A 120V AC panel-mounted toggle switch applications. The actuator length difference does not affect electrical performance or mechanical mounting compatibility when panel cutout and bushing specifications remain constant.

Frequently Asked Questions (FAQ)

Q: Can the 100DP3T1B9M2QEH replace the 7203MH3CGE in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: DPDT circuit, 5A current rating, 120V AC / 28V DC voltage ratings, panel mount configuration, PC pin termination, and identical panel cutout dimensions (6.35mm circular). The actuator length difference (4.57mm vs. 10.41mm) does not affect substitution when panel geometry remains unchanged.

Q: What is the significance of the actuator length difference?

A: Actuator length affects the physical feel and appearance of the switch lever but does not impact electrical function or panel mounting compatibility. Both lengths are compatible with standard 1/4-40 bushing threads and 6.35mm circular panel cutouts. Design considerations should account for operator ergonomics and panel aesthetics.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant with EAR99 ECCN classification and identical HTSUS codes. The primary difference is REACH status: the 7203MH3CGE is REACH Affected, while the 100DP3T1B9M2QEH is REACH Unaffected. For applications subject to REACH regulations, the E-Switch part may offer simplified compliance documentation.

Q: What electrical life expectancy should be assumed for these switches?

A: Both parts are rated for 40,000 electrical cycles under specified operating conditions (5A, 120V AC / 28V DC, -30°C ~ 85°C). This rating applies to the mechanical switching action and contact durability.

Q: Are these switches suitable for AC and DC applications?

A: Yes. Both parts are rated for 5A operation at 120V AC and 28V DC, making them suitable for mixed AC/DC control circuits within these voltage and current parameters.
