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

Part Overview

The C&K 7201SCWCQI is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch is designed for On-On applications with IP67 ingress protection and epoxy potting for enhanced durability. The part is currently active in production with 1,032 units in stock. Substitute parts may be required due to supply constraints, end-of-life considerations, or specific application requirements that align with alternative electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SCWCQI 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)
• Panel cutout dimensions (Circular 6.35mm Dia required)
• Bushing thread (1/4-40 required)
• Termination style (PC Pin required)
• Operating temperature range (-30°C to 85°C minimum required)

Electrical Compatibility Criteria:

• Current rating must meet or exceed 5A (AC/DC)
• Voltage rating must meet or exceed 120V AC and 28V DC

The substitute parts listed below meet the primary compatibility criteria. However, electrical ratings vary and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

100DP1T1B1M2QEH (E-Switch): This substitute maintains full electrical compatibility with the 7201SCWCQI, matching both 5A current rating and 120V AC / 28V DC voltage specifications. All mechanical parameters align identically. The part is ROHS3 compliant and currently active in production with 8,013 units in stock. Electrical life is reduced to 40,000 cycles compared to the original 100,000 cycles.

100DP1T6B15M2RE (E-Switch): This part meets all mechanical compatibility requirements but operates at reduced electrical ratings (0.4VA at 20V AC/DC). Selection of this substitute is limited to applications where the lower voltage and current specifications are acceptable. The part is ROHS3 compliant and active in production with 830 units in stock.

2-1825138-4 (TE Connectivity ALCOSWITCH Switches): This part meets all mechanical compatibility requirements but operates at reduced electrical ratings (0.4VA at 20V AC/DC). Selection of this substitute is limited to applications where the lower voltage and current specifications are acceptable. The part is ROHS3 compliant and REACH affected, with 1,751 units in stock. Electrical life is significantly reduced to 6,000 cycles.

Frequently Asked Questions (FAQ)

Q: Can 100DP1T1B1M2QEH directly replace the 7201SCWCQI? A: Yes, within the constraints of mechanical panel mounting and electrical specifications. The 100DP1T1B1M2QEH maintains identical voltage and current ratings (5A, 120V AC, 28V DC), panel cutout dimensions (6.35mm), bushing thread (1/4-40), and termination style (PC Pin). Electrical life is reduced from 100,000 to 40,000 cycles.

Q: What are the limitations of 100DP1T6B15M2RE and 2-1825138-4? A: Both parts operate at significantly lower electrical ratings (0.4VA at 20V AC/DC) compared to the original 5A at 120V AC specification. These substitutes are suitable only for low-voltage, low-current applications. The 2-1825138-4 additionally exhibits reduced electrical life (6,000 cycles).

Q: Are all substitute parts panel-mount compatible with the original mounting hole? A: Yes. All substitute parts share identical panel cutout dimensions (6.35mm circular) and bushing thread specifications (1/4-40), ensuring mechanical compatibility with existing panel installations.

Q: What is the impact of reduced electrical life in substitute parts? A: The 7201SCWCQI is rated for 100,000 electrical cycles. The E-Switch 100 series substitutes are rated for 40,000 cycles, and the TE Connectivity 2-1825138-4 is rated for 6,000 cycles. Applications requiring high cycle counts should account for more frequent replacement intervals with substitute parts.

Q: Are all parts RoHS3 compliant? A: Yes. The 7201SCWCQI and all listed substitute parts are ROHS3 compliant. The 2-1825138-4 is additionally REACH affected.

Q: What packaging formats are available? A: The 7201SCWCQI is supplied in Tray packaging. All substitute parts are supplied in Bulk packaging. Packaging format should be verified against procurement requirements.
