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

Part Overview

The C&K 7203SDCGE is an active production toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V 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 REACH affected, with an operating temperature range of -30°C to 85°C.

Substitute parts are identified when equivalent electrical ratings, mechanical mounting specifications, and circuit configurations are available from alternative manufacturers, enabling procurement flexibility while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7203SDCGE 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 encompass -30°C ~ 85°C
• Electrical life must meet or exceed 40,000 cycles
• RoHS3 compliance status must be maintained

The E-Switch 100DP3T1B1M2REH meets these mechanical and functional criteria. However, electrical ratings differ: the substitute is rated for 0.4VA at 20V AC/DC, which represents a lower power capacity than the main part's 5A at 120V AC / 28V DC rating. Substitution is valid only when the application's actual electrical requirements do not exceed the substitute's ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7203SDCGE and E-Switch 100DP3T1B1M2REH maintain ROHS3 compliance and identical mechanical specifications for panel mounting. The primary differentiation lies in electrical ratings and regulatory status.

The C&K 7203SDCGE is the specified part for applications requiring 5A switching capacity at 120V AC or 28V DC. The E-Switch 100DP3T1B1M2REH is suitable only for low-power applications with maximum requirements of 0.4VA at 20V AC/DC. Selection between these parts must be based on actual circuit power requirements and voltage levels.

The E-Switch substitute offers the advantage of REACH unaffected status, which may simplify supply chain compliance in certain regulatory jurisdictions. The C&K main part's REACH affected status requires appropriate documentation and compliance procedures.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M2REH replace the C&K 7203SDCGE in all applications?

A: No. The E-Switch substitute has significantly lower electrical ratings (0.4VA at 20V versus 5A at 120V AC / 28V DC). Substitution is valid only when the application's actual power consumption and voltage requirements do not exceed the substitute's specifications.

Q: Are the panel mounting dimensions identical?

A: Yes. Both parts feature a circular 6.35mm diameter panel cutout and 1/4-40 bushing thread, enabling direct mechanical interchange in panel-mount installations.

Q: What is the difference in actuator length between these parts?

A: The C&K 7203SDCGE has a 12.45mm actuator length, while the E-Switch 100DP3T1B1M2REH has a 10.41mm actuator length. This 2.04mm difference may affect panel aesthetics and operator feel but does not impact electrical function.

Q: Do both parts have identical electrical life ratings?

A: Yes. Both parts are rated for 40,000 electrical cycles, providing equivalent operational durability.

Q: What is the significance of REACH status differences?

A: The C&K part is REACH affected, requiring compliance documentation for European supply chains. The E-Switch substitute is REACH unaffected, potentially simplifying regulatory compliance in certain markets. Selection should consider regional regulatory requirements.

Q: Are PC pin terminations compatible between these parts?

A: Yes. Both parts use PC pin termination style, enabling direct electrical connection compatibility in applications designed for this termination method.
