GS01MCKE Equivalent & Substitute Parts

Part Overview

The GS01MCKE is a slide switch with SPDT (Single Pole Double Throw) configuration manufactured by C&K. It is rated for 0.4VA at 20V AC/DC and features a through-hole mounting design with gold-plated beryllium copper contacts. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The GS01MCBE qualifies as a direct substitute for the GS01MCKE based on the following critical parameters:

• Circuit Configuration: Both parts are SPDT with identical On-On switch function
• Electrical Ratings: Both rated for 0.4VA at 20V AC/DC
• Mechanical Specifications: Identical actuator length (1.27mm), switch travel (1.02mm), and mechanical/electrical life (40,000 cycles)
• Mounting and Termination: Both use through-hole mounting with PC pin termination
• Physical Features: Both feature epoxy sealed terminals and polyetherimide actuator material
• Contact Finish: Both have gold-plated contacts

The primary differences are contact material composition and operating temperature range, which do not prevent functional substitution within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The GS01MCBE is the appropriate substitute for the obsolete GS01MCKE. Both parts maintain identical electrical and mechanical specifications across all critical parameters including circuit configuration, voltage/current ratings, actuator dimensions, and lifecycle ratings.

The GS01MCBE offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, the GS01MCBE achieves ROHS3 compliance, addressing regulatory requirements that may apply to new designs or system updates.

The extended operating temperature range of the GS01MCBE (-40°C to 85°C versus -30°C to 85°C) provides additional thermal margin without compromising performance within the original specification envelope.

Frequently Asked Questions (FAQ)

Q: Can GS01MCBE directly replace GS01MCKE in existing assemblies?

A: Yes. Both parts share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (SPDT), mechanical dimensions (1.27mm actuator length, 1.02mm travel), and mounting specifications (through-hole with PC pin termination). The parts are mechanically and electrically interchangeable.

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

A: GS01MCKE uses beryllium copper contacts while GS01MCBE uses copper contacts. Both are gold-plated and rated for identical electrical performance at the specified 0.4VA and 20V ratings.

Q: Why is GS01MCKE marked as obsolete?

A: GS01MCKE is no longer in active production. GS01MCBE serves as the current production equivalent within the GS series, maintaining all functional and electrical specifications.

Q: Does the packaging difference affect compatibility?

A: No. GS01MCKE is supplied in bulk packaging while GS01MCBE is supplied in tray packaging. This affects only procurement and handling; the electrical and mechanical performance of the switch itself is identical.

Q: Is GS01MCBE suitable for new designs?

A: Yes. GS01MCBE is an active product with ROHS3 compliance, making it appropriate for new designs and systems requiring regulatory compliance.

Q: What is the temperature operating range difference?

A: GS01MCBE operates from -40°C to 85°C compared to GS01MCKE's -30°C to 85°C range. This extended lower temperature limit provides additional margin for applications in cold environments.
