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

Part Overview

The C&K 7203SPHCGE 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 an anti-rotation brass actuator with epoxy sealed terminals and is designed for On-Off-On switching applications. Finding equivalent substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility in component sourcing.

• Voltage rating: 120V AC / 28V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: 6.35mm circular
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 cycles

Substitute Parts Identified:

1. 100DP3T1B9M2QEH (E-Switch) - Full electrical and mechanical equivalence with identical current and voltage ratings
2. 100DP3T1B1M2REH (E-Switch) - Mechanical and mounting equivalence with reduced electrical ratings (0.4VA at 20V AC/DC)

Parameter Comparison

Engineering Selection Recommendations

100DP3T1B9M2QEH (E-Switch Series 100) is the direct electrical and mechanical equivalent to the 7203SPHCGE. This substitute maintains identical current ratings (5A AC/DC), voltage specifications (120V AC / 28V DC), and all mechanical parameters including panel cutout dimensions and bushing thread specifications. Both parts are ROHS3 compliant and active in production status. This substitute provides full interchangeability for applications requiring the specified electrical performance.

100DP3T1B1M2REH (E-Switch Series 100) shares identical mechanical and mounting characteristics but operates at reduced electrical ratings (0.4VA at 20V AC/DC). This part is suitable only for applications where the lower voltage and current specifications are acceptable. The REACH status differs (Unaffected vs. Affected), which may be relevant for specific regulatory requirements.

Both E-Switch alternatives are ROHS3 compliant and maintain the same operating temperature range and electrical life specifications as the original C&K part.

Frequently Asked Questions (FAQ)

Q: Can 100DP3T1B9M2QEH be used as a direct replacement for 7203SPHCGE?

A: Yes. The 100DP3T1B9M2QEH provides full electrical and mechanical equivalence. Both parts feature identical DPDT On-Off-On configuration, 5A current rating at 120V AC and 28V DC, panel mount design with 6.35mm circular cutout, 1/4-40 bushing thread, and PC pin termination. Operating temperature range and electrical life specifications are identical.

Q: What are the limitations of using 100DP3T1B1M2REH as a substitute?

A: The 100DP3T1B1M2REH has reduced electrical ratings (0.4VA at 20V AC/DC compared to 5A at 120V AC / 28V DC). This part is mechanically compatible but electrically suitable only for low-voltage, low-current applications. Use this substitute only when application requirements do not exceed 0.4VA at 20V.

Q: Are all substitute parts panel-mount compatible with the same cutout dimensions?

A: Yes. All listed substitutes feature identical panel mount specifications: 6.35mm circular cutout diameter and 1/4-40 bushing thread. Physical installation compatibility is maintained across all parts.

Q: Do the substitute parts meet the same compliance standards?

A: All substitute parts are ROHS3 compliant and active in production. The 100DP3T1B9M2QEH maintains the same REACH Affected status as the original 7203SPHCGE. The 100DP3T1B1M2REH is REACH Unaffected, which may be relevant for specific regulatory applications.

Q: What is the difference in actuator design between the main part and substitutes?

A: The 7203SPHCGE features an anti-rotation brass actuator (10.67mm length), while both E-Switch substitutes use a standard round brass actuator (10.41mm length). Both actuator types are brass with chrome plating and suitable for the specified operating temperature range.
