C&K 7203TCWCLE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203TCWCLE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch features an On-Off-On function with IP67 ingress protection and epoxy-sealed terminals for harsh environment applications. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203TCWCLE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Bushing thread: 15/32-32
• Actuator type: Standard Round
• Actuator length: 17.45mm

Electrical Performance Criteria:

• Current rating: Minimum 5A (AC/DC)
• Voltage rating - AC: Minimum 120V
• Voltage rating - DC: Minimum 28V
• Operating temperature range: Must encompass -30°C to 85°C

Environmental & Mechanical Criteria:

• Ingress protection: IP67 or equivalent
• Panel cutout dimensions: Circular 11.91mm Dia
• Actuator material: Brass, Chrome Plated
• Features: Epoxy Sealed Terminals

Substitute parts are grouped into two categories: Direct Manufacturer Equivalents (same manufacturer, same series) and Similar Cross-Manufacturer Alternatives (different manufacturer, equivalent electrical and mechanical specifications).

Engineering Selection Recommendations

C&K 7203TCWCRE (Direct Equivalent - Recommended Primary Substitute)

The 7203TCWCRE is the direct successor to the obsolete 7203TCWCLE within the C&K 7000 series. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), mechanical dimensions, and environmental specifications (IP67, -30°C to 85°C). The primary distinction is product status: 7203TCWCRE is active and in production, ensuring long-term availability. The 7203TCWCRE achieves RoHS compliance and REACH affected status, making it suitable for applications requiring regulatory compliance. This part is the preferred substitute for direct replacement in existing designs.

Electroswitch A221T1TXCQ (Cross-Manufacturer Alternative)

The A221T1TXCQ provides a functionally equivalent alternative from a different manufacturer. It exceeds the original specification in current rating (6A versus 5A) and electrical life (60,000 cycles versus 40,000 cycles), offering enhanced performance margins. The operating temperature range extends to 90°C, providing additional thermal headroom. However, ingress protection is rated as Splash Proof rather than IP67 (Dust Tight, Waterproof), representing a reduction in environmental sealing capability. The A221T1TXCQ is RoHS compliant and suitable for applications where higher current capacity and extended cycle life are beneficial. Panel cutout dimensions are not specified for this part; mechanical fit verification is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 7203TCWCRE directly replace the 7203TCWCLE without circuit modifications?

A: Yes. The 7203TCWCRE maintains identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), switch function (On-Off-On), mechanical dimensions, and termination style (PC Pin). No circuit modifications are required for direct substitution.

Q: What is the difference between the 7203TCWCRE and A221T1TXCQ in terms of environmental protection?

A: The 7203TCWCRE provides IP67 ingress protection (Dust Tight, Waterproof). The A221T1TXCQ is rated for Splash Proof protection, which is a lower environmental sealing standard. For applications requiring full dust and water immersion protection, the 7203TCWCRE is the appropriate choice.

Q: Is the A221T1TXCQ suitable for applications requiring higher current capacity?

A: Yes. The A221T1TXCQ is rated for 6A (AC/DC) compared to the original 5A specification. This provides a 20% increase in current capacity and is suitable for applications where higher current margins are required. The electrical life is also extended to 60,000 cycles.

Q: What compliance certifications apply to each substitute part?

A: The 7203TCWCLE (original) is RoHS non-compliant. The 7203TCWCRE is RoHS compliant and REACH affected. The A221T1TXCQ is RoHS compliant with REACH status listed as Vendor Undefined. For applications requiring RoHS compliance, both substitute parts meet this requirement.

Q: Are there packaging differences between these parts?

A: The 7203TCWCLE and 7203TCWCRE packaging information is not specified in the technical data. The A221T1TXCQ is supplied in Bulk packaging. Confirm packaging requirements with your procurement department before finalizing part selection.

Q: What is the panel cutout requirement for the A221T1TXCQ?

A: Panel cutout dimensions for the A221T1TXCQ are not provided in the technical specification. The 7203TCWCLE and 7203TCWCRE both require a circular cutout of 11.91mm diameter. Obtain detailed mechanical drawings from Electroswitch before implementing the A221T1TXCQ in new panel designs.
