C&K 7108SD9ALE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7108SD9ALE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted switch features a standard round actuator with epoxy sealed terminals and is designed for On-Mom (momentary) operation. The 7108SD9ALE is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7108SD9ALE 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 (Through Hole, Right Angle)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)
• Base product number (7108SD)

The C&K 7108SD9ARE meets all these criteria and serves as a direct substitute. The primary distinction is product status: the 7108SD9ALE is obsolete, while the 7108SD9ARE is active and available for new designs.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7108SD9ARE is the direct substitute for the obsolete 7108SD9ALE. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs without modification.

The 7108SD9ARE offers the additional advantage of RoHS compliance, making it suitable for applications subject to RoHS regulations. The REACH Affected status of the 7108SD9ARE indicates regulatory documentation availability for supply chain compliance purposes.

For new designs or procurement of replacement inventory, the 7108SD9ARE should be specified in place of the 7108SD9ALE.

Frequently Asked Questions (FAQ)

Q: Can the 7108SD9ARE be used as a direct replacement for the 7108SD9ALE in existing assemblies?

A: Yes. The 7108SD9ARE is electrically and mechanically identical to the 7108SD9ALE. All electrical ratings, mounting dimensions, and actuator specifications are equivalent. No circuit modifications or mechanical redesign is required.

Q: What is the difference between the two parts?

A: The primary differences are product status and regulatory compliance. The 7108SD9ALE is obsolete, while the 7108SD9ARE is active. The 7108SD9ARE is RoHS compliant, whereas the 7108SD9ALE is not. Both parts are from the same C&K 7000 series and share the same base product number (7108SD).

Q: Are there any packaging or lead-time considerations when switching to the 7108SD9ARE?

A: Both parts use PC Pin termination and through-hole, right-angle mounting. Packaging specifications were not provided in the technical data. Verify packaging requirements with your supplier to ensure compatibility with assembly processes.

Q: Does the RoHS compliance of the 7108SD9ARE affect performance?

A: No. RoHS compliance indicates material composition restrictions but does not alter electrical performance, current rating, voltage rating, or operating temperature range. The 7108SD9ARE maintains all functional specifications of the 7108SD9ALE.

Q: Is the 7108SD9ARE suitable for applications requiring REACH documentation?

A: Yes. The 7108SD9ARE is REACH Affected, meaning REACH compliance documentation is available. The 7108SD9ALE is REACH Unaffected. For applications requiring REACH documentation, the 7108SD9ARE is the appropriate choice.
