C&K 7201P3DCQI Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P3DCQI is an active production toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features a flat anti-rotation actuator and is designed for general-purpose switching applications requiring reliable electrical performance across industrial and commercial environments. Substitute parts may be required due to inventory constraints, end-of-life considerations, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with 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)

Secondary Compatibility Criteria:

• Current and voltage ratings must meet or exceed application requirements
• Actuator type and length may vary if mechanical constraints permit
• Electrical life specifications vary by substitute part

The substitute parts listed below maintain full compatibility with the primary criteria. Variations in current rating, voltage rating, actuator type, and electrical life are noted in the parameter comparison table and must be evaluated against specific application requirements.

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH is the primary substitute for applications requiring equivalent electrical performance. This part maintains the 5A/120V AC and 28V DC ratings of the original C&K 7201P3DCQI, ensuring direct functional compatibility. Both parts are ROHS3 compliant and operate across the identical temperature range. The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles), which must be evaluated against application duty cycle requirements. Actuator type differs (Standard Round versus Flat Anti-Rotation), requiring mechanical clearance verification in the panel assembly.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are suitable only for applications with reduced voltage and current requirements (0.4VA at 20V maximum). These parts are not suitable as direct replacements for the original 5A/120V specification. Selection of these parts requires confirmation that the application operates within the 0.4VA/20V envelope. The TE Connectivity part exhibits significantly reduced electrical life (6,000 cycles) and should be evaluated for applications with lower switching frequency requirements.

All substitute parts maintain mechanical compatibility through identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and termination style (PC Pin). Product status is active for all listed parts, ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M2QEH directly replace the C&K 7201P3DCQI?

A: Yes, for electrical specifications. Both parts are rated 5A at 120V AC and 28V DC with DPDT On-On configuration. Mechanical differences include actuator type (Standard Round versus Flat Anti-Rotation) and actuator length (10.41mm versus 13.21mm). Panel cutout, bushing thread, and termination are identical. Verify mechanical clearance in the panel assembly before substitution.

Q: Why do E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 have lower current and voltage ratings?

A: These parts are designed for low-signal switching applications and are not rated for the 5A/120V performance envelope of the original part. They are suitable only for applications operating at 0.4VA maximum at 20V or lower. Substitution requires confirmation that application requirements do not exceed these limits.

Q: What is the significance of electrical life differences?

A: Electrical life indicates the number of switching cycles a part is rated to perform before degradation. The C&K 7201P3DCQI is rated for 100,000 cycles, while E-Switch substitutes are rated for 40,000 cycles, and the TE Connectivity part for 6,000 cycles. Applications with high switching frequency or long operational life should account for these differences in component selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original C&K 7201P3DCQI.

Q: Do actuator type differences affect electrical performance?

A: No. Actuator type (Flat Anti-Rotation versus Standard Round) affects mechanical operation and panel assembly fit, not electrical switching performance. Verify that the selected actuator type accommodates mechanical constraints in the application.

Q: What packaging differences exist between the main part and substitutes?

A: The C&K 7201P3DCQI is supplied in Tray packaging, while all E-Switch and TE Connectivity substitutes are supplied in Bulk packaging. Confirm packaging requirements for procurement and inventory management.
