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

Part Overview

The C&K 7203SCWCGE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch is designed for On-Off-On applications requiring robust electrical switching in industrial and commercial environments. The part is currently active in production with 1010 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility, supply chain alternatives, and compatibility options for system integrators and equipment manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7203SCWCGE are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit Configuration: DPDT topology must be maintained
• Switch Function: On-Off-On operation required
• Mounting Interface: Panel mount with 1/4-40 bushing thread and 6.35mm circular cutout
• Termination: PC pin termination for PCB compatibility
• Operating Temperature: -30°C to 85°C range
• Electrical Life: 40,000 cycles minimum
• Actuator Material: Brass, chrome-plated construction
• Epoxy Sealed Terminals: Required for environmental protection

Two E-Switch alternatives meet these core mechanical and functional requirements. Electrical ratings vary between the substitutes, creating two distinct substitution categories based on application voltage and current demands.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Full Electrical Rating Match): The E-Switch 100DP3T1B9M2QEH provides complete electrical and mechanical equivalence to the 7203SCWCGE. Both parts share identical current (5A AC/DC), voltage (120V AC / 28V DC), and all mechanical interface specifications. This substitute is suitable for direct replacement in applications requiring the full electrical specification. Both parts are ROHS3 compliant and carry active product status.

Reduced Rating Substitute (Lower Voltage/Current Application): The E-Switch 100DP3T1B1M2REH is suitable only for applications operating at 20V AC/DC with 0.4VA current requirements. This part maintains all mechanical compatibility and functional characteristics but operates at reduced electrical ratings. Selection of this substitute requires verification that application voltage and current demands do not exceed 20V and 0.4VA respectively. This part is ROHS3 compliant and carries active product status.

Compliance Considerations: All three parts are ROHS3 compliant. The main part (7203SCWCGE) is REACH Affected, while both E-Switch substitutes are REACH Unaffected. The main part provides IP67 ingress protection; E-Switch alternatives do not specify ingress protection ratings.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B9M2QEH replace the C&K 7203SCWCGE in all applications? A: Yes, the 100DP3T1B9M2QEH provides complete electrical and mechanical equivalence. All electrical ratings, mounting interfaces, termination styles, and environmental specifications are identical. Both parts support the same operating temperature range and electrical life cycle.

Q: What is the key difference between the two E-Switch substitutes? A: The 100DP3T1B9M2QEH matches the full electrical specification (5A, 120V AC, 28V DC), while the 100DP3T1B1M2REH is rated for reduced voltage and current (0.4VA, 20V AC/DC). Selection depends on application electrical requirements.

Q: Are there mechanical compatibility concerns between the C&K and E-Switch parts? A: No. All three parts share identical panel mount interfaces: 6.35mm circular cutout, 1/4-40 bushing thread, and PC pin termination. Actuator length varies slightly (10.67mm vs 10.41mm), but this does not affect panel mounting or electrical function.

Q: What is the impact of the missing ingress protection specification on E-Switch parts? A: The main part specifies IP67 protection (dust tight, waterproof). E-Switch substitutes do not provide ingress protection ratings. Applications requiring sealed environmental protection should retain the C&K 7203SCWCGE or verify E-Switch ingress protection through direct manufacturer consultation.

Q: Are all parts suitable for the same operating temperature range? A: Yes. All three parts operate across -30°C to 85°C, supporting identical thermal requirements.

Q: What is the electrical life expectancy for these switches? A: All three parts are rated for 40,000 electrical cycles, providing equivalent operational longevity.
