Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7201SYCBI is determined by strict alignment of the following critical parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Product status: Active

The identified substitute parts meet these core electrical and mechanical parameters. Variations in actuator type, actuator length, electrical life cycles, and feature implementations (epoxy potting vs. sealed terminals) do not preclude substitution when the primary functional and dimensional specifications align.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the C&K 7201SYCBI. Selection among substitutes should be based on the following considerations:

E-Switch 100AWDP1T1B1M2REH: Offers IP67 ingress protection, providing enhanced environmental sealing suitable for applications requiring dust and moisture resistance. Electrical life is rated at 30,000 cycles.

E-Switch 100DP1T6B15M2RE: Features a flat anti-rotation actuator design with extended actuator length (12.30mm). Electrical life is rated at 40,000 cycles. This variant is suitable for applications where actuator geometry and anti-rotation properties are beneficial.

TE Connectivity 2-1825138-4: Provides a standard round actuator with 10.41mm length. Electrical life is rated at 6,000 cycles. This part is suitable for applications with lower cycle count requirements.

The E-Switch 100DP1T1B1M2QEH is not recommended as a direct substitute due to its higher current rating (5A) and voltage specifications (120V AC, 28V DC), which exceed the 0.4VA 20V requirements of the primary application.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH be used as a substitute for the C&K 7201SYCBI?

A: No. The E-Switch 100DP1T1B1M2QEH has a current rating of 5A and voltage ratings of 120V AC and 28V DC, which do not align with the 0.4VA 20V specification of the C&K 7201SYCBI. This part is designed for higher-power applications and is not electrically compatible.

Q: What is the significance of the actuator type difference between the C&K 7201SYCBI and E-Switch 100DP1T6B15M2RE?

A: The C&K 7201SYCBI uses a standard round actuator, while the E-Switch 100DP1T6B15M2RE uses a flat anti-rotation actuator. Both are mechanically compatible with the 6.35mm circular panel cutout and 1/4-40 bushing thread. The flat anti-rotation design prevents unintended rotation of the actuator during operation. Selection depends on application-specific mechanical requirements.

Q: How do electrical life ratings affect substitution decisions?

A: Electrical life ratings indicate the number of switching cycles a component can withstand before performance degradation. The C&K 7201SYCBI is rated for 100,000 cycles, while substitutes range from 6,000 to 40,000 cycles. For applications requiring high cycle counts, the C&K 7201SYCBI or E-Switch 100DP1T6B15M2RE are preferred. For lower-cycle applications, all substitutes are acceptable.

Q: What does IP67 ingress protection on the E-Switch 100AWDP1T1B1M2REH provide?

A: IP67 rating indicates dust-tight and waterproof protection. The E-Switch 100AWDP1T1B1M2REH is suitable for applications exposed to moisture, dust, or submersion up to 1 meter for 30 minutes. The C&K 7201SYCBI does not specify ingress protection and is suitable for standard indoor control applications.

Q: Are all substitute parts available in the same packaging as the C&K 7201SYCBI?

A: The C&K 7201SYCBI is supplied in Tray packaging. E-Switch and TE Connectivity substitutes are supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility but may impact procurement and handling procedures.

Q: Do all parts meet the same compliance standards?

A: All identified parts are ROHS3 compliant and active-status products. The C&K 7201SYCBI is REACH Affected, while E-Switch parts are REACH Unaffected. TE Connectivity 2-1825138-4 is REACH Affected. Compliance status should be verified against specific application and regional requirements.
