Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U43TCWV71LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (4PDT)
• Switch function (On-Off-On)
• Current and voltage ratings (5A AC/DC, 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 specification (15/32-32)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)

The U43TCWV71RE meets all these criteria and is classified as an active product within the same C&K 7000 series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The U43TCWV71RE is a direct substitute for the obsolete U43TCWV71LE. Both components share identical electrical, mechanical, and environmental specifications within the C&K 7000 series. The U43TCWV71RE is currently in active production status with higher inventory availability (1122 units versus 762 units for the obsolete part).

Compliance considerations: The U43TCWV71LE carries ROHS3 Compliant and REACH Unaffected designations, while the U43TCWV71RE is RoHS Compliant and REACH Affected. Both components share the same ECCN (EAR99) and HTSUS classification (8536.50.9065). Selection between these parts should account for specific regulatory requirements applicable to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Are U43TCWV71LE and U43TCWV71RE electrically interchangeable?

A: Yes. Both components are 4PDT toggle switches with identical electrical ratings (5A at 120V AC / 28V DC), switch function (On-Off-On), and operating temperature range (-30°C ~ 85°C). They share the same circuit configuration and electrical life specification (40,000 cycles).

Q: Are these parts mechanically interchangeable?

A: Yes. Both components feature identical panel mount specifications, including circular 11.91mm diameter cutout, 15/32-32 bushing thread, standard round actuator with 17.45mm length, and PC Pin termination style.

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

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. The U43TCWV71LE carries ROHS3 Compliant status, while the U43TCWV71RE carries RoHS Compliant status. Regulatory applicability depends on the target market and end-use application.

Q: What does REACH Affected versus REACH Unaffected mean?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) status indicates regulatory obligations. The U43TCWV71LE is REACH Unaffected, while the U43TCWV71RE is REACH Affected. Compliance requirements vary by jurisdiction and application.

Q: Why is the U43TCWV71LE listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The U43TCWV71RE serves as the active equivalent for ongoing procurement and system support.

Q: Can I use U43TCWV71RE in applications originally designed for U43TCWV71LE?

A: Yes, provided that the regulatory compliance profile (RoHS and REACH status) aligns with application requirements. All electrical, mechanical, and environmental specifications are identical.
