C&K 7201SYCPE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SYCPE is an active-status panel mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This switch is designed for applications requiring reliable on-on switching functionality with epoxy sealed terminals and a standard round actuator. Substitute parts are identified to provide equivalent electrical and mechanical performance for applications where the original part is unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SYCPE are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit Configuration: DPDT (required match)
• Switch Function: On-On (required match)
• Current Rating: 0.4VA AC/DC (required match for direct substitution)
• Voltage Rating: 20V AC and 20V DC (required match for direct substitution)
• Mounting Type: Panel Mount (required match)
• Panel Cutout Dimensions: Circular 6.35mm Dia (required match)
• Bushing Thread: 1/4-40 (required match)
• Termination Style: PC Pin (required match)
• Operating Temperature Range: -30°C to 85°C (required match)

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents. Deviations in secondary parameters such as actuator type, actuator length, electrical life, or ingress protection are noted but do not disqualify substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical and Mechanical Equivalents (0.4VA, 20V Rating):

The following parts meet all primary substitution criteria and are classified as direct equivalents for the 7201SYCPE:

• 100AWDP1T1B1M2REH (E-Switch): Matches all electrical specifications. Features IP67 ingress protection. Electrical life rated at 30,000 cycles versus 100,000 cycles for the original part. ROHS3 compliant and REACH unaffected.

• 100DP1T6B15M2RE (E-Switch): Matches all electrical specifications. Actuator type differs (Flat Anti-Rotation versus Standard Round) with increased actuator length (12.30mm versus 10.67mm). Electrical life rated at 40,000 cycles. ROHS3 compliant and REACH unaffected.

• 2-1825138-4 (TE Connectivity ALCOSWITCH): Matches all electrical specifications. Electrical life rated at 6,000 cycles, significantly lower than the original part. Actuator material is Brass, Nickel Plated versus Brass, Chrome Plated. ROHS3 compliant and REACH affected.

Non-Equivalent Part (Higher Electrical Rating):

• 100DP1T1B1M2QEH (E-Switch): Does not meet primary substitution criteria. Current rating is 5A AC/DC with voltage ratings of 120V AC and 28V DC. This part is rated for higher electrical loads and is not suitable as a direct substitute for 0.4VA, 20V applications.

All equivalent parts maintain ROHS3 compliance and active product status. Selection should account for differences in electrical life cycles and specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T1B1M2QEH be used as a substitute for the 7201SYCPE?

A: No. The 100DP1T1B1M2QEH has a current rating of 5A and voltage ratings of 120V AC / 28V DC, which exceed the 0.4VA, 20V specifications of the 7201SYCPE. This part is designed for higher electrical loads and is not electrically compatible.

Q: What is the primary difference between the 100AWDP1T1B1M2REH and the 7201SYCPE?

A: Both parts match all primary electrical and mechanical specifications. The 100AWDP1T1B1M2REH provides IP67 ingress protection (dust tight, waterproof) and has a lower electrical life rating of 30,000 cycles compared to 100,000 cycles for the original part.

Q: Does the 100DP1T6B15M2RE have a different actuator?

A: Yes. The 100DP1T6B15M2RE features a Flat Anti-Rotation actuator with a length of 12.30mm, compared to the Standard Round actuator of 10.67mm on the 7201SYCPE. Panel mounting dimensions remain compatible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The 2-1825138-4 is REACH affected, while the E-Switch parts are REACH unaffected.

Q: What is the electrical life difference between the original part and substitutes?

A: The 7201SYCPE is rated for 100,000 electrical cycles. The 100AWDP1T1B1M2REH is rated for 30,000 cycles, the 100DP1T6B15M2RE for 40,000 cycles, and the 2-1825138-4 for 6,000 cycles. Application duty cycle requirements should guide selection.

Q: Can the 2-1825138-4 be used in applications requiring high cycle counts?

A: The 2-1825138-4 has an electrical life rating of 6,000 cycles, significantly lower than the original 7201SYCPE at 100,000 cycles. Selection should be based on specific application cycle requirements.
