C&K 7109SDCLE Toggle Switch SPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7109SDCLE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with epoxy sealed PC pin termination and operates across a temperature range of -30°C to 85°C. The 7109SDCLE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7109SDCLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• 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 7109SDCRE meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts lies in product status and regulatory compliance, not in electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7109SDCRE is the direct substitute for the obsolete 7109SDCLE. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The 7109SDCRE is currently in active production status, providing supply continuity for applications requiring SPDT toggle switches with 5A/120V AC ratings and panel mount configuration.

The 7109SDCRE achieves RoHS compliance, whereas the 7109SDCLE does not. For new designs or systems subject to RoHS regulatory requirements, the 7109SDCRE is the appropriate selection. Both components carry EAR99 ECCN classification and share identical HTSUS coding (8536.50.9065).

Frequently Asked Questions (FAQ)

Q: Can the 7109SDCRE directly replace the 7109SDCLE in existing applications?

A: Yes. The 7109SDCRE is electrically and mechanically equivalent to the 7109SDCLE. Both components feature identical current ratings (5A AC/DC), voltage ratings (120V AC, 28V DC), circuit configuration (SPDT), mounting type (panel mount), and physical dimensions. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The 7109SDCRE is in active production status, while the 7109SDCLE is obsolete. Additionally, the 7109SDCRE is RoHS compliant, whereas the 7109SDCLE is not. These differences do not affect electrical or mechanical performance.

Q: Are the panel cutout dimensions identical?

A: Yes. Both the 7109SDCLE and 7109SDCRE require a circular panel cutout of 6.35mm diameter with 1/4-40 bushing thread specification. Panel modifications are not required for substitution.

Q: Do both parts operate across the same temperature range?

A: Yes. Both components operate from -30°C to 85°C and maintain 40,000 electrical life cycles under identical conditions.

Q: Which part should be selected for new designs?

A: The 7109SDCRE should be selected for new designs. It provides active production support, RoHS compliance, and identical functional performance to the obsolete 7109SDCLE.
