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

Part Overview

The C&K 7201SDCBE is an active production toggle switch with DPDT (Double Pole Double Throw) configuration rated for 0.4VA at 20V AC/DC. This panel-mount switch features a standard round actuator with epoxy sealed terminals and is designed for applications requiring reliable switching in the low-voltage, low-current range. Substitute parts are identified based on matching electrical ratings, mechanical compatibility, and functional equivalence within the DPDT toggle switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SDCBE are identified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• 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 ~ 85°C

Electrical Compatibility Parameters:

• Current rating: 0.4VA (AC/DC) or higher
• Voltage rating: 20V AC/DC minimum

The identified substitutes meet these core requirements. Parts with higher current or voltage ratings remain compatible for applications designed for the 7201SDCBE, as they operate within the same mechanical envelope and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Matched Current and Voltage Ratings):

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are direct electrical equivalents to the C&K 7201SDCBE, matching the 0.4VA current rating and 20V voltage specifications. Both are ROHS3 compliant and active production parts. The E-Switch 100DP1T6B15M2RE features a flat anti-rotation actuator, while the TE Connectivity 2-1825138-4 uses a standard round actuator matching the original design.

Higher-Rated Alternative:

E-Switch 100DP1T1B1M2QEH provides enhanced electrical capacity (5A at 120V AC, 28V DC) while maintaining mechanical compatibility. This part is suitable for applications requiring higher current or voltage headroom within the same panel-mount footprint. ROHS3 compliant and active production status.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and active product status. The C&K 7201SDCBE and TE Connectivity 2-1825138-4 are both REACH Affected. The E-Switch alternatives are REACH Unaffected, which may be relevant for specific regulatory environments.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH (5A, 120V) be used in place of the C&K 7201SDCBE (0.4VA, 20V)?

A: Yes. The E-Switch 100DP1T1B1M2QEH maintains identical mechanical compatibility (panel cutout, bushing thread, termination style) and DPDT On-On configuration. Higher electrical ratings do not prevent substitution in applications designed for lower ratings. The part is ROHS3 compliant and in active production.

Q: What is the primary difference between the E-Switch 100DP1T6B15M2RE and the TE Connectivity 2-1825138-4?

A: Both are direct electrical equivalents with matched 0.4VA and 20V ratings. The E-Switch features a flat anti-rotation actuator (12.30mm length), while the TE Connectivity uses a standard round actuator (10.41mm length). Actuator type selection depends on panel design and user interface requirements.

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

A: The C&K 7201SDCBE is supplied in Tray packaging. E-Switch alternatives (100DP1T6B15M2RE and 100DP1T1B1M2QEH) and TE Connectivity 2-1825138-4 are supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do substitute parts meet the same environmental specifications?

A: All substitute parts operate within the -30°C ~ 85°C temperature range matching the original. All are ROHS3 compliant. REACH compliance differs: C&K 7201SDCBE and TE Connectivity 2-1825138-4 are REACH Affected; E-Switch parts are REACH Unaffected. Verify REACH requirements for your specific application region.

Q: What electrical life expectancy should be considered when selecting a substitute?

A: The C&K 7201SDCBE is rated for 100,000 electrical cycles. E-Switch alternatives are rated for 40,000 cycles, and the TE Connectivity 2-1825138-4 is rated for 6,000 cycles. Select based on application duty cycle requirements.
