Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7403TCWV71LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 17.45mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread (15/32-32)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7403TCWV71RE meets all these criteria and qualifies as a direct substitute within the 7000 series.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7403TCWV71RE is the direct substitute for the obsolete 7403TCWV71LE. Both components are manufactured by C&K within the 7000 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the 7403TCWV71LE is obsolete while the 7403TCWV71RE is active. The 7403TCWV71RE carries RoHS compliance certification and is REACH affected, whereas the 7403TCWV71LE is REACH unaffected. Both components satisfy equivalent environmental and regulatory requirements for their respective classifications.

Selection of the 7403TCWV71RE ensures access to an actively manufactured component with equivalent functional performance and identical mechanical fit for panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 7403TCWV71RE directly replace the 7403TCWV71LE in existing designs?

A: Yes. Both components share identical circuit configuration (4PDT), electrical ratings (5A at 120V AC), mechanical dimensions (11.91mm circular cutout, 15/32-32 bushing thread), and actuator specifications (Standard Round, 17.45mm). Panel mount installation is identical.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. Both designations indicate compliance with RoHS requirements; the terminology reflects different regulatory documentation versions.

Q: Does the REACH Affected status of the 7403TCWV71RE affect substitution suitability?

A: No. REACH Affected status indicates the component is subject to REACH registration requirements. This is a regulatory classification that does not alter electrical or mechanical performance. The component remains suitable for direct substitution.

Q: Are the ingress protection ratings identical between both parts?

A: Yes. Both the 7403TCWV71LE and 7403TCWV71RE maintain IP67 rating (dust tight, waterproof), ensuring equivalent environmental protection in panel mount applications.

Q: What is the electrical life specification for both components?

A: Both components are rated for 40,000 electrical cycles, indicating equivalent mechanical durability and switch contact life under specified operating conditions.
