C&K 7203SYWLE Toggle Switch DPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7203SYWLE 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 wire wrap termination and epoxy sealed terminals. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (Wire Wrap)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7203SYWRE meets all these criteria and qualifies as a direct substitute for the obsolete 7203SYWLE.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7203SYWRE is the direct functional equivalent of the obsolete 7203SYWLE. Both parts share identical electrical and mechanical specifications across all critical parameters including circuit configuration, current and voltage ratings, mounting dimensions, and operating characteristics.

The primary distinction between these parts is regulatory compliance status. The 7203SYWRE is ROHS3 compliant and REACH affected, whereas the 7203SYWLE is RoHS non-compliant and REACH unaffected. For applications subject to RoHS3 or REACH regulatory requirements, the 7203SYWRE is the appropriate selection. The 7203SYWRE is currently in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 7203SYWRE directly replace the 7203SYWLE in existing designs?

A: Yes. The 7203SYWRE is electrically and mechanically identical to the 7203SYWLE. Panel cutout dimensions, bushing thread specifications, actuator geometry, and all electrical ratings are equivalent. Direct substitution is possible without design modification.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The 7203SYWLE is obsolete and RoHS non-compliant. The 7203SYWRE is active production and ROHS3 compliant. All functional and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The 7203SYWLE is supplied in standard packaging. The 7203SYWRE is supplied in bulk packaging. Both contain the same component.

Q: Which part should be selected for new designs?

A: The 7203SYWRE should be selected for new designs. It is in active production status and meets current RoHS3 compliance requirements.

Q: Are the wire wrap terminations compatible between these parts?

A: Yes. Both parts use identical wire wrap termination style and are compatible with the same terminal connection methods.
