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

Part Overview

The C&K 7203SPHCQE 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 operates in an On-Off-On function with anti-rotation actuator design and is classified as Active product status. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where electrical and mechanical parameters remain compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7203SPHCQE are identified based on strict compatibility criteria. The primary substitution parameters are:

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

Two E-Switch toggle switches meet these criteria with differing electrical specifications. The 100DP3T1B9M2QEH provides full electrical equivalence to the 7203SPHCQE. The 100DP3T1B1M2REH operates at reduced voltage and current ratings and is suitable only for applications with lower electrical demands.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch 100DP3T1B9M2QEH is the primary equivalent substitute for the C&K 7203SPHCQE. Both parts maintain identical electrical ratings (5A at 120V AC and 28V DC), mechanical mounting specifications, and operating temperature range. Both are ROHS3 compliant and Active product status. The minor difference in actuator type (anti-rotation versus standard round) and actuator length (10.67mm versus 10.41mm) does not affect electrical or functional compatibility in standard panel-mount applications.

The E-Switch 100DP3T1B1M2REH is a reduced-specification alternative suitable only for applications operating at 20V AC/DC maximum with current demands not exceeding 0.4VA. This part shares identical mechanical mounting and environmental specifications but operates at significantly lower electrical ratings. Selection of this part requires confirmation that application voltage and current requirements do not exceed its rated specifications.

Both E-Switch substitutes are ROHS3 compliant and carry Active product status, ensuring regulatory compliance and ongoing manufacturer support equivalent to the original C&K part.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B9M2QEH directly replace the C&K 7203SPHCQE in all applications?

A: Yes, the 100DP3T1B9M2QEH provides direct electrical and mechanical compatibility. Both parts are rated for 5A at 120V AC and 28V DC with identical DPDT On-Off-On circuit configuration, panel-mount specifications, and operating temperature range. The actuator design difference (anti-rotation versus standard round) does not affect functional compatibility.

Q: When is the E-Switch 100DP3T1B1M2REH appropriate for use?

A: The 100DP3T1B1M2REH is suitable only for applications with maximum voltage requirements of 20V AC/DC and current demands not exceeding 0.4VA. Applications requiring the full 5A at 120V AC rating must use the 100DP3T1B9M2QEH or the original C&K 7203SPHCQE.

Q: Are the panel cutout dimensions identical across all three parts?

A: Yes. All three parts require a circular panel cutout of 6.35mm diameter with 1/4-40 bushing thread, ensuring mechanical interchangeability in existing panel installations.

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

A: Yes. Both E-Switch substitutes are ROHS3 compliant with Active product status, matching the regulatory compliance profile of the C&K 7203SPHCQE.

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

A: The C&K 7203SPHCQE has an actuator length of 10.67mm, while both E-Switch substitutes have 10.41mm actuators. This 0.26mm difference is within standard mechanical tolerances and does not affect panel-mount installation or operational performance.

Q: Are the electrical life ratings equivalent?

A: Yes. All three parts are rated for 40,000 electrical cycles, ensuring equivalent operational longevity in switching applications.
