C&K 7108SYW4ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7108SYW4ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The switch features wire wrap termination, epoxy sealed terminals, and a standard round actuator with 10.67mm length, suitable for applications requiring reliable switching in industrial and commercial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7108SYW4ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (Wire Wrap)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)
• Features (Epoxy Sealed Terminals)

The C&K 7108SYW4SE maintains complete electrical and mechanical compatibility with the 7108SYW4ME across all specified parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7108SYW4SE is the direct functional equivalent for the obsolete 7108SYW4ME. Both components share identical electrical ratings, mechanical dimensions, and operational characteristics. The primary distinction is product status and regulatory compliance: the 7108SYW4SE is an active product with RoHS compliance certification, whereas the 7108SYW4ME is obsolete and RoHS non-compliant.

For new designs and ongoing production requiring compliance with current environmental regulations, the 7108SYW4SE is the appropriate selection. For legacy system maintenance where the original 7108SYW4ME specification must be maintained, the 7108SYW4SE provides complete drop-in compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 7108SYW4SE directly replace the 7108SYW4ME in existing applications?

A: Yes. The 7108SYW4SE maintains identical electrical ratings (5A at 120V AC / 28V DC), mechanical dimensions (6.35mm circular panel cutout, 1/4-40 bushing thread), actuator specifications (10.67mm standard round), and termination style (wire wrap). No circuit or mechanical modifications are required.

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

A: The 7108SYW4ME is classified as obsolete, while the 7108SYW4SE is an active product. The 7108SYW4SE carries RoHS compliance certification, whereas the 7108SYW4ME does not. Both parts are electrically and mechanically equivalent.

Q: Are there any compatibility concerns with panel cutout dimensions?

A: No. Both parts specify identical panel cutout dimensions (circular 6.35mm diameter) and bushing thread specification (1/4-40), ensuring mechanical interchangeability in existing panel installations.

Q: Does the 7108SYW4SE meet current regulatory requirements?

A: The 7108SYW4SE is RoHS compliant and REACH affected, meeting current environmental and chemical safety regulations. The obsolete 7108SYW4ME does not carry these certifications.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the same temperature range of -30°C to 85°C with identical electrical life specifications of 40,000 cycles.
