7201SY4CGE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The 7201SY4CGE is an active production toggle switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) configuration with On-On switching function. This panel mount switch is rated for 5A at 120V AC and 28V DC, with a standard round actuator and PC pin termination. The part is currently in stock with 826 units available. Equivalent and substitute parts may be required due to inventory constraints, application-specific requirements, or design revisions that allow for alternative electrical or mechanical specifications within acceptable parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SY4CGE is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (DPDT required)
• Switch function (On-On required)
• Mounting type (Panel Mount required)
• Termination style (PC Pin required)
• Panel cutout dimensions (Circular 6.35mm Dia required)
• Bushing thread (1/4-40 required)
• Operating temperature range (-30°C to 85°C minimum required)

Secondary Compatibility Criteria:

• Current and voltage ratings must meet or exceed application requirements
• Actuator type and length variations are acceptable if mechanical fit is verified
• Electrical life ratings may vary based on application duty cycle
• Packaging format (Tray vs. Bulk) does not affect electrical compatibility

The substitute parts listed below meet the primary compatibility criteria. Variations in electrical ratings, actuator specifications, and electrical life are noted in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

100DP1T1B1M2QEH (E-Switch): This part maintains full electrical compatibility with the 7201SY4CGE, matching the 5A/120V AC and 28V DC ratings. The actuator length variation of 0.26mm is within mechanical tolerance for standard panel mount applications. Electrical life is reduced to 40,000 cycles; this part is suitable for applications with moderate duty cycles. REACH Unaffected status may provide supply chain advantages in certain regions.

100DP1T6B15M2RE (E-Switch): This part features reduced electrical ratings (0.4VA/20V) and is suitable only for low-power applications. The Flat Anti-Rotation actuator type and increased actuator length (12.30mm) represent mechanical differences that require panel design verification. Electrical life of 40,000 cycles is appropriate for moderate-duty applications within the reduced voltage specification.

2-1825138-4 (TE Connectivity ALCOSWITCH): This part meets primary compatibility criteria but features significantly reduced electrical life (6,000 cycles) and lower voltage ratings (20V AC/DC). The Nickel Plated actuator material differs from the Brass Chrome Plated specification. This part is suitable only for low-cycle-count applications. Moisture Sensitivity Level is Not Applicable, indicating different packaging considerations.

All substitute parts maintain ROHS3 compliance and are suitable for the -30°C to 85°C operating temperature range specified for the main part.

Frequently Asked Questions (FAQ)

Q: Can 100DP1T1B1M2QEH be used as a direct replacement for 7201SY4CGE?

A: Yes, 100DP1T1B1M2QEH is electrically and mechanically compatible. Both parts share identical DPDT On-On configuration, 5A/120V AC and 28V DC ratings, PC pin termination, and panel mount specifications. The 0.26mm actuator length difference is within standard mechanical tolerance for panel cutout applications.

Q: What are the limitations of 100DP1T6B15M2RE as a substitute?

A: 100DP1T6B15M2RE has reduced electrical ratings (0.4VA/20V versus 5A/120V) and is suitable only for low-power applications. The Flat Anti-Rotation actuator type and 12.30mm actuator length require mechanical fit verification against the original 10.67mm specification. This part is not suitable for applications requiring the full 5A/120V capability.

Q: When should 2-1825138-4 be considered?

A: 2-1825138-4 meets the primary compatibility criteria for DPDT On-On panel mount configuration but features significantly reduced electrical life (6,000 cycles) and lower voltage ratings (20V). This part is suitable only for low-cycle-count, low-voltage applications. The Nickel Plated actuator material differs from the original specification.

Q: Does packaging format affect electrical compatibility?

A: No. Packaging format (Tray versus Bulk) does not affect electrical or mechanical compatibility. Selection between packaging formats is determined by procurement and inventory management requirements only.

Q: Are all substitute parts RoHS and REACH compliant?

A: All substitute parts are ROHS3 compliant. REACH status varies: 100DP1T1B1M2QEH and 100DP1T6B15M2RE are REACH Unaffected, while 2-1825138-4 is REACH Affected, matching the original 7201SY4CGE status.

Q: What is the primary difference in electrical life between the main part and substitutes?

A: The 7201SY4CGE is rated for 100,000 cycles. E-Switch substitutes (100DP1T1B1M2QEH and 100DP1T6B15M2RE) are rated for 40,000 cycles. The TE Connectivity part (2-1825138-4) is rated for 6,000 cycles. Selection should be based on application duty cycle requirements.
