C&K 7101TV3LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101TV3LE is a panel mount toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 7101TV series provides reliable switching functionality with epoxy sealed terminals and a standard round actuator suitable for industrial control applications.

• Mounting type: Panel Mount or Through Hole
• Panel cutout dimensions: Circular - 11.91mm Dia
• Bushing thread: 15/32-32
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Note: Current and voltage ratings are reduced; electrical life is reduced

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The C&K 7101TV3RE is the recommended direct substitute for the obsolete 7101TV3LE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), mechanical dimensions, and termination specifications. The 7101TV3RE maintains active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

For Reduced-Load Applications: The E-Switch 100SP1T8B13VS2RE and 100SP1T8B13VS2REH are suitable substitutes only for applications where current and voltage requirements do not exceed 0.4VA at 20V AC/DC. These parts maintain mechanical compatibility through identical panel cutout dimensions and bushing threads. The 100SP1T8B13VS2REH offers through-hole mounting as an alternative to panel mount configuration. Both E-Switch parts have reduced electrical life (40,000 cycles versus 100,000 cycles) and should be evaluated against application duty cycle requirements.

Compliance Considerations: All substitute parts maintain the operating temperature range of -30°C to 85°C. The 7101TV3RE and 100SP1T8B13VS2REH are ROHS3 compliant. The 7101TV3RE is REACH affected, while the 7101TV3LE and 100SP1T8B13VS2REH are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T8B13VS2RE be used as a direct replacement for the C&K 7101TV3LE? A: No. While both parts share SPDT configuration and mechanical compatibility, the E-Switch part has significantly reduced electrical ratings (0.4VA at 20V versus 5A at 120V AC / 28V DC). Use only if your application operates within the lower electrical specifications.

Q: What is the primary difference between 100SP1T8B13VS2RE and 100SP1T8B13VS2REH? A: The primary difference is mounting type. The 100SP1T8B13VS2RE is panel mount, while the 100SP1T8B13VS2REH is through-hole. All other electrical and mechanical specifications are identical.

Q: Is the C&K 7101TV3RE available in the same packaging as the 7101TV3LE? A: The 7101TV3LE was supplied in standard packaging. The 7101TV3RE is the active equivalent and is available through standard distribution channels.

Q: What is the impact of reduced electrical life in the E-Switch parts? A: The E-Switch 100 series parts are rated for 40,000 cycles versus 100,000 cycles for the C&K 7000 series. Applications requiring frequent switching should account for this reduced cycle life in maintenance planning.

Q: Are all substitute parts suitable for the same temperature range? A: Yes. All listed substitute parts operate across the same temperature range of -30°C to 85°C.

Q: What are the key mechanical compatibility factors? A: Panel cutout diameter (11.91mm circular), bushing thread (15/32-32), and PC pin termination are consistent across all parts, ensuring mechanical interchangeability in panel mount applications.
