C&K 7203T1V3LE2 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203T1V3LE2 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The switch features a standard round actuator with PC pin termination and operates across a temperature range of -30°C to 85°C with an electrical life of 40,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7203T1V3LE2 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread (15/32-32)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

Electrical Rating Considerations:

• Current rating must support the application requirements
• Voltage ratings (AC and DC) must meet or exceed system specifications
• Actuator type and length must be compatible with panel mounting

Substitutes are classified into two categories: direct manufacturer alternatives from C&K and similar alternatives from other manufacturers that meet the same functional and mechanical specifications.

Engineering Selection Recommendations

C&K 7203T1V3RE2 (Direct Substitute - Recommended for Primary Replacement)

The 7203T1V3RE2 is the preferred direct substitute for the obsolete 7203T1V3LE2. Both components share identical electrical ratings (5A at 120V AC / 28V DC), mechanical specifications, and operational characteristics. The primary distinction is product status: the 7203T1V3RE2 is active and currently in production with 1,175 units in stock. The 7203T1V3RE2 achieves RoHS compliance and is REACH affected, representing improved environmental and regulatory alignment compared to the non-compliant main part. The epoxy sealed terminals feature provides enhanced durability in demanding environments.

Grayhill Inc. 34ADP38T7V3RT (Similar Substitute - Application-Dependent)

The 34ADP38T7V3RT serves as a similar substitute when electrical rating constraints permit. This component maintains identical mechanical compatibility (panel cutout, bushing thread, mounting type) and circuit configuration (DPDT, On-Off-On). However, the 34ADP38T7V3RT operates at reduced electrical ratings (0.4VA at 20V AC/DC), making it suitable only for low-power applications. The actuator length differs at 17.45mm compared to 12.37mm, requiring panel geometry verification. The 34ADP38T7V3RT is RoHS compliant and REACH unaffected, with 959 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 7203T1V3RE2 directly replace the 7203T1V3LE2 without modification?

A: Yes. The 7203T1V3RE2 is mechanically and electrically identical to the 7203T1V3LE2. Both components feature the same panel cutout dimensions (11.91mm circular), bushing thread (15/32-32), actuator length (12.37mm), electrical ratings (5A at 120V AC / 28V DC), and operational specifications. No panel modifications or circuit redesign are required.

Q: What are the electrical limitations of the Grayhill 34ADP38T7V3RT substitute?

A: The 34ADP38T7V3RT is rated for 0.4VA at 20V AC/DC, compared to the main part's 5A at 120V AC / 28V DC. This substitute is suitable only for low-power signal switching applications. Applications requiring the full 5A capacity or 120V AC operation must use the C&K 7203T1V3RE2.

Q: Are there mechanical compatibility concerns with the Grayhill substitute?

A: The Grayhill 34ADP38T7V3RT maintains panel mounting compatibility through identical panel cutout dimensions and bushing thread specifications. However, the actuator length is 17.45mm compared to 12.37mm on the main part. Panel geometry and clearance must be verified to ensure the longer actuator does not interfere with surrounding components or panel structure.

Q: What is the inventory status for each substitute?

A: The C&K 7203T1V3RE2 has 1,175 units in stock. The Grayhill 34ADP38T7V3RT has 959 units in stock. Both substitutes are currently available for immediate procurement.

Q: How do RoHS and REACH compliance differ between the main part and substitutes?

A: The main part 7203T1V3LE2 is RoHS non-compliant and REACH unaffected. The C&K 7203T1V3RE2 is RoHS compliant and REACH affected. The Grayhill 34ADP38T7V3RT is RoHS compliant and REACH unaffected. Applications subject to RoHS or REACH regulations should specify the 7203T1V3RE2 or 34ADP38T7V3RT accordingly.
