C&K 7203K9V3LE2 Toggle Switch DPDT — Equivalent & Substitute Parts

Part Overview

The C&K 7203K9V3LE2 is a through-hole mounted toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This switch features a locking lever actuator with black anodized finish and is designed for On-Off-On switching applications. The part is classified as obsolete, making identification of active equivalent substitutes necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution eligibility for the 7203K9V3LE2 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT only
• Switch Function: On-Off-On operation
• Current Rating: 5A (AC/DC)
• Voltage Ratings: 120V AC and 28V DC minimum
• Mounting Type: Through Hole
• Actuator Type: Locking Lever
• Actuator Length: 17.88mm
• Termination Style: PC Pin
• Operating Temperature Range: -30°C to 85°C
• Electrical Life: 40,000 Cycles minimum
• Base Product Number: 7203K9 series

The C&K 7203K9V3RE2 meets all these criteria and is classified as a direct manufacturer equivalent within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7203K9V3RE2 is the direct functional equivalent of the 7203K9V3LE2. Both parts share identical electrical ratings, mechanical dimensions, and switching characteristics. The primary distinction is product lifecycle status: the 7203K9V3LE2 is obsolete, while the 7203K9V3RE2 is active and currently manufactured.

For new designs and production continuity, the 7203K9V3RE2 is the appropriate selection. This substitute offers improved compliance posture: it is RoHS Compliant and REACH Affected, compared to the non-compliant status of the original part. Both parts carry the same ECCN (EAR99) and HTSUS classification.

The 7203K9V3RE2 features epoxy sealed terminals, providing enhanced environmental protection compared to the black anodized finish of the original. This represents a design improvement within the same functional class.

Frequently Asked Questions (FAQ)

Q: Can the 7203K9V3RE2 be used as a direct replacement for the 7203K9V3LE2?

A: Yes. Both parts are DPDT toggle switches with identical electrical ratings (5A at 120V AC / 28V DC), mechanical dimensions (17.88mm locking lever), and switching function (On-Off-On). They share the same base product number (7203K9) and termination style (PC Pin through-hole). Electrical and mechanical compatibility is complete.

Q: What is the difference between the two parts?

A: The primary differences are product status and terminal protection. The 7203K9V3LE2 is obsolete with black anodized finish and RoHS non-compliant status. The 7203K9V3RE2 is active production with epoxy sealed terminals and RoHS Compliant certification. Both meet identical functional and electrical specifications.

Q: Are there any compatibility concerns with PCB layout or panel cutout dimensions?

A: No. Both parts use identical through-hole PC pin termination and the same 17.88mm locking lever actuator. Panel cutout dimensions are equivalent. No design modifications are required for substitution.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical switching performance and electrical ratings.

Q: What is the inventory status for each part?

A: The 7203K9V3LE2 has 717 pieces in stock (obsolete status). The 7203K9V3RE2 has 1,142 pieces in stock (active production). For new procurement, the 7203K9V3RE2 is the recommended source.
