C&K 7108P3D9V4KES Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7108P3D9V4KES is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This through-hole mounted switch features a flat anti-rotation actuator with satin chrome finish and is designed for On-Momentary switching applications. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7108P3D9V4KES is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Electrical Ratings: Current (0.4VA) and voltage (20V AC/DC) specifications must be met or exceeded
• Mounting Interface: Through-hole mounting with PC pin termination required
• Mechanical Compatibility: Actuator type (flat anti-rotation), length (13.21mm), and operating temperature range (-30°C to 85°C) must match
• Switching Characteristics: On-Momentary function and 40,000-cycle electrical life minimum
• Base Product Compatibility: Parts sharing the 7108P3 base product number within the 7000 series

The C&K 7108P3D9V4PES qualifies as a direct substitute based on identical electrical, mechanical, and functional parameters. The primary distinction is product status (active vs. obsolete) and terminal treatment (epoxy sealed vs. satin chrome).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7108P3D9V4PES is the primary substitute for the obsolete 7108P3D9V4KES. Both parts are manufactured by C&K within the 7000 series and share identical electrical and mechanical specifications. The substitute part is currently in active production status, ensuring supply chain continuity and availability.

From a compliance perspective, the substitute part maintains RoHS compliance (RoHS vs. RoHS3 designation reflects regulatory timeline updates rather than functional differences). Both parts carry EAR99 export classification and are subject to identical HTSUS tariff codes.

The terminal treatment differs between the two parts: the original features satin chrome actuators, while the substitute incorporates epoxy sealed terminals. This design variation does not affect electrical performance or mechanical compatibility in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the 7108P3D9V4PES directly replace the 7108P3D9V4KES in existing designs?

A: Yes. Both parts share identical SPDT circuit configuration, electrical ratings (0.4VA at 20V AC/DC), mechanical dimensions, and through-hole PC pin termination. No design modifications are required.

Q: What is the significance of the product status change from obsolete to active?

A: The substitute part is in current production, ensuring reliable supply and consistent manufacturing quality. The obsolete designation of the original part indicates it is no longer manufactured by C&K.

Q: Are there differences in RoHS compliance between these parts?

A: Both parts are RoHS compliant. The RoHS3 designation on the original part reflects compliance with the most recent regulatory directive, while the substitute carries the RoHS designation. Both meet current environmental compliance requirements.

Q: How do the terminal treatments differ, and does this affect PCB compatibility?

A: The original part features satin chrome actuators, while the substitute includes epoxy sealed terminals. This difference pertains to terminal protection and does not affect electrical performance or through-hole mounting compatibility on standard PCBs.

Q: Are the actuator dimensions identical between both parts?

A: Yes. Both parts feature flat anti-rotation actuators with a length of 13.21mm and operate across the same temperature range (-30°C to 85°C).

Q: What is the electrical life expectancy for both parts?

A: Both the 7108P3D9V4KES and 7108P3D9V4PES are rated for 40,000 switching cycles under specified electrical conditions.
