U15TCWV71LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U15TCWV71LE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability. The switch features momentary-off-momentary (Mom-Off-Mom) operation with IP67 ingress protection and epoxy-sealed terminals suitable for harsh environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U15TCWV71LE is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (5A AC/DC), and voltage ratings (120V AC / 28V DC)
• Mechanical Compatibility: Mounting type (panel mount), panel cutout dimensions (11.91mm circular), bushing thread (15/32-32), and termination style (PC Pin)
• Environmental Performance: Ingress protection rating (IP67), operating temperature range (-30°C to 85°C), and sealed terminal construction
• Reliability: Electrical life specification (40,000 cycles)

The U15TCWV71RE qualifies as a direct substitute based on complete alignment across all specified parameters. The primary distinction is product status: U15TCWV71LE is obsolete while U15TCWV71RE is active.

Parameter Comparison

Engineering Selection Recommendations

The U15TCWV71RE is the direct equivalent for the obsolete U15TCWV71LE. Both components are manufactured by C&K within the 7000 series and maintain identical electrical, mechanical, and environmental specifications. The U15TCWV71RE is the recommended selection for new designs and replacement applications due to its active product status and continued manufacturer support.

Compliance considerations: The U15TCWV71RE carries RoHS Compliant certification and REACH Affected status, compared to the U15TCWV71LE's ROHS3 Compliant and REACH Unaffected designations. Both components maintain EAR99 export classification and identical HTSUS coding. MSL rating of 1 (Unlimited) applies to both parts, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can U15TCWV71RE directly replace U15TCWV71LE in existing assemblies?

A: Yes. The U15TCWV71RE provides complete functional and mechanical equivalence. Panel cutout dimensions, bushing thread specifications, and PC pin termination are identical, enabling direct substitution without PCB or enclosure modifications.

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

A: ROHS3 refers to RoHS Directive 2011/65/EU as amended by Directive (EU) 2015/863. RoHS Compliant indicates adherence to the RoHS framework. Both designations confirm restriction of hazardous substances; the specific version designation reflects the regulatory framework under which compliance was assessed.

Q: Does REACH Affected status impact component selection?

A: REACH Affected status indicates the component is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This is a regulatory classification and does not affect electrical or mechanical performance. Compliance documentation should be obtained from the manufacturer for supply chain documentation.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both components are rated for 5A at 120V AC and 28V DC with SPDT Mom-Off-Mom operation. Operating temperature range (-30°C to 85°C) and electrical life (40,000 cycles) are identical.

Q: What is the significance of the 15/32-32 bushing thread specification?

A: This specification defines the panel mounting interface. The 15/32-32 thread ensures proper mechanical engagement with standard panel cutouts of 11.91mm diameter. Both parts use identical threading, confirming mechanical interchangeability.
