GS02MCKE Equivalent & Substitute Parts

Part Overview

The GS02MCKE is a slide switch SPST (Single Pole Single Throw) manufactured by C&K, rated for 0.4VA at 20V with through-hole mounting. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The GS02MCKE features beryllium copper contacts with gold finish, epoxy sealed terminals, and is rated for 40,000 mechanical and electrical cycles across an operating temperature range of -30°C to 85°C.

Substitute Part Grouping Explanation

Substitution eligibility for the GS02MCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Switch function (On-Off)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Actuator type and dimensions (Standard, 1.27mm length)
• Switch travel distance (1.02mm)
• Contact finish (Gold)
• Mechanical and electrical life ratings (40,000 cycles minimum)

The GS02MCBE qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and functional characteristics within the GS series. Both components share the same circuit topology, voltage/current ratings, mounting configuration, and lifecycle ratings. The primary distinction lies in contact material composition and product status, with GS02MCBE offering active availability and enhanced compliance certifications.

Engineering Selection Recommendations

The GS02MCBE is the designated substitute for the obsolete GS02MCKE. Both components meet identical electrical and mechanical specifications required for SPST switching applications at 0.4VA and 20V ratings. The GS02MCBE provides the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS3 compliance satisfies current regulatory requirements for new designs
• Extended operating temperature range (-40°C to 85°C versus -30°C to 85°C) provides broader environmental tolerance
• Copper contact material maintains functional equivalence while supporting modern manufacturing standards

Selection of GS02MCBE is appropriate for applications requiring direct replacement of GS02MCKE in existing designs or for new implementations requiring equivalent SPST switching functionality within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can GS02MCBE directly replace GS02MCKE in existing PCB designs?

A: Yes. Both components share identical mounting type (through hole), termination style (PC pin), actuator dimensions (1.27mm length), and switch travel (1.02mm). No PCB layout modifications are required.

Q: What is the difference in contact material between these parts?

A: GS02MCKE uses beryllium copper contacts, while GS02MCBE uses copper contacts. Both are finished with gold plating and maintain equivalent electrical performance at the specified 0.4VA and 20V ratings.

Q: Does the operating temperature range difference affect substitution?

A: GS02MCBE supports -40°C to 85°C compared to GS02MCKE's -30°C to 85°C. This represents an extended lower temperature capability in GS02MCBE, making it suitable for all applications where GS02MCKE was used.

Q: Why is GS02MCKE classified as obsolete?

A: Product obsolescence reflects C&K's discontinuation of this part number. GS02MCBE remains in active production and provides equivalent functionality for ongoing procurement needs.

Q: Are there packaging differences between these parts?

A: GS02MCKE is supplied with dash packaging, while GS02MCBE is supplied in trays. Both packaging formats are suitable for through-hole assembly processes.

Q: What compliance certifications apply to GS02MCBE?

A: GS02MCBE is RoHS3 compliant and REACH unaffected. GS02MCKE is RoHS non-compliant. For new designs subject to RoHS requirements, GS02MCBE is the appropriate selection.

Q: Are the mechanical and electrical life ratings identical?

A: Yes. Both components are rated for 40,000 mechanical cycles and 40,000 electrical cycles, ensuring equivalent reliability and service life in switching applications.
