C&K 7109SD9CLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7109SD9CLE is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This through-hole mounted switch features a standard round actuator with epoxy sealed terminals and is designed for On-Mom (momentary) operation. The 7109SD9CLE is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The 7109SD9CLE can be substituted with the 7109SD9CRE based on the following electrical and mechanical compatibility criteria:

Matching Parameters (Substitution Basis):

• Identical circuit configuration (SPDT)
• Identical switch function (On-Mom)
• Identical current rating (5A AC/DC)
• Identical voltage ratings (120V AC, 28V DC)
• Identical mounting type (Through Hole)
• Identical actuator type and length (Standard Round, 12.45mm)
• Identical termination style (PC Pin)
• Identical operating temperature range (-30°C to 85°C)
• Identical electrical life (40,000 Cycles)
• Identical base product number (7109SD)
• Same manufacturer (C&K)
• Same series (7000)

Differentiating Factors:

• Packaging: 7109SD9CLE supplied in standard packaging; 7109SD9CRE supplied in Tray
• Product Status: 7109SD9CLE is Obsolete; 7109SD9CRE is Active
• RoHS Compliance: 7109SD9CLE is RoHS non-compliant; 7109SD9CRE is RoHS3 Compliant
• REACH Status: 7109SD9CLE is REACH Unaffected; 7109SD9CRE is REACH Affected

Parameter Comparison

Engineering Selection Recommendations

The 7109SD9CRE is the direct substitute for the obsolete 7109SD9CLE. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction is product status and regulatory compliance.

The 7109SD9CRE is recommended for new designs and ongoing procurement due to its Active product status and RoHS3 compliance. For applications requiring RoHS non-compliant components or where REACH Unaffected status is mandatory, the 7109SD9CLE may be sourced from existing inventory if available.

Packaging differences (standard vs. Tray) do not affect electrical or mechanical compatibility and should be evaluated based on assembly and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7109SD9CRE directly replace the 7109SD9CLE in existing designs?

A: Yes. The 7109SD9CRE is electrically and mechanically identical to the 7109SD9CLE. All electrical ratings, switching characteristics, mounting dimensions, and actuator specifications are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between the packaging options?

A: The 7109SD9CLE is supplied in standard packaging, while the 7109SD9CRE is supplied in Tray packaging. This affects only component handling, storage, and assembly processes. Electrical and mechanical performance are unaffected.

Q: Why is the 7109SD9CLE classified as obsolete?

A: The 7109SD9CLE is no longer in active production. The 7109SD9CRE serves as the current production equivalent with improved regulatory compliance (RoHS3).

Q: Are there compliance differences between these parts?

A: Yes. The 7109SD9CRE is RoHS3 Compliant and REACH Affected, while the 7109SD9CLE is RoHS non-compliant and REACH Unaffected. Applications subject to RoHS or REACH regulations should use the 7109SD9CRE.

Q: Do both parts have the same electrical life rating?

A: Yes. Both the 7109SD9CLE and 7109SD9CRE are rated for 40,000 electrical cycles, ensuring equivalent operational longevity.

Q: Are the actuator dimensions identical?

A: Yes. Both parts feature a standard round actuator with a length of 12.45mm, ensuring identical panel cutout and mounting requirements.
