Toggle Switch DPDT 7201SDCGE Equivalent & Substitute Parts

Part Overview

The C&K 7201SDCGE is an active-status toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with epoxy-sealed PC pin termination and operates across -30°C to 85°C. The part is ROHS3 compliant and maintains an electrical life of 100,000 cycles. Substitute parts are identified for applications requiring equivalent DPDT panel-mount toggle switch functionality with compatible mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SDCGE is determined by the following critical parameters: DPDT circuit configuration, On-On switch function, panel-mount mechanical interface, PC pin termination, circular 6.35mm panel cutout, 1/4-40 bushing thread, and operating temperature range of -30°C to 85°C. All identified substitutes maintain these core mechanical and functional specifications.

Electrical rating compatibility is categorized into two groups:

Group 1 - Full Electrical Compatibility (5A @ 120V AC / 28V DC): Part 100DP1T1B1M2QEH maintains identical current and voltage ratings to the main part.

Group 2 - Reduced Electrical Rating (0.4VA @ 20V AC/DC): Parts 100DP1T6B15M2RE and 2-1825138-4 operate at lower voltage and current specifications and are suitable only for applications within their rated parameters.

Parameter Comparison

Engineering Selection Recommendations

100DP1T1B1M2QEH (E-Switch): This substitute maintains full electrical compatibility with the 7201SDCGE, supporting 5A at 120V AC and 28V DC. Both parts are ROHS3 compliant and operate across the same temperature range. The E-Switch part is REACH Unaffected, which may provide regulatory advantage in certain supply chain contexts. Electrical life is reduced to 40,000 cycles compared to the original 100,000 cycles. Actuator length is 10.41mm versus 12.45mm on the original part.

100DP1T6B15M2RE (E-Switch): This part operates at reduced electrical ratings of 0.4VA at 20V AC/DC and is suitable only for low-voltage, low-current applications. It features a flat anti-rotation actuator type and is REACH Unaffected. Selection of this substitute requires confirmation that application voltage and current demands do not exceed 20V and 0.4VA respectively.

2-1825138-4 (TE Connectivity ALCOSWITCH Switches): This Gemini A series part operates at 0.4VA at 20V AC/DC with significantly reduced electrical life of 6,000 cycles. It is REACH Affected and has Not Applicable moisture sensitivity level. This substitute is suitable only for low-voltage applications and applications with lower cycle count requirements.

Frequently Asked Questions (FAQ)

Q: Can 100DP1T1B1M2QEH directly replace 7201SDCGE in all applications?

A: 100DP1T1B1M2QEH maintains identical electrical ratings (5A @ 120V AC / 28V DC), circuit configuration (DPDT), and mechanical interface (panel mount, 6.35mm cutout, 1/4-40 bushing). The primary difference is reduced electrical life (40,000 versus 100,000 cycles). Direct substitution is valid for applications where the lower cycle count is acceptable.

Q: What are the limitations of 100DP1T6B15M2RE and 2-1825138-4?

A: Both parts operate at reduced electrical ratings of 0.4VA at 20V AC/DC. These substitutes are not suitable for applications requiring 5A at 120V AC or 28V DC. Selection requires verification that the application operates within 20V and 0.4VA maximum specifications.

Q: Are there mechanical compatibility concerns with actuator length differences?

A: Actuator lengths vary across the substitute parts (10.41mm to 12.45mm). Panel cutout dimensions and bushing threads remain consistent at 6.35mm circular and 1/4-40 respectively. Mechanical compatibility depends on panel thickness and actuator engagement requirements specific to the application.

Q: What is the significance of REACH status differences?

A: The original 7201SDCGE and 2-1825138-4 are REACH Affected, while 100DP1T1B1M2QEH and 100DP1T6B15M2RE are REACH Unaffected. REACH Unaffected status may simplify regulatory compliance in certain supply chain and geographic contexts.

Q: How do electrical life ratings compare?

A: The 7201SDCGE provides 100,000 cycles. E-Switch parts (100DP1T1B1M2QEH and 100DP1T6B15M2RE) provide 40,000 cycles. The TE Connectivity part (2-1825138-4) provides 6,000 cycles. Application cycle count requirements determine acceptable substitutes.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All parts listed—7201SDCGE, 100DP1T1B1M2QEH, 100DP1T6B15M2RE, and 2-1825138-4—are ROHS3 compliant.
