GT12MCKE Toggle Switch SPST Equivalent & Substitute Parts

Part Overview

The GT12MCKE is a toggle switch manufactured by C&K, classified as SPST (Single Pole Single Throw) with On-Off functionality. This through-hole mounted component is rated for 0.4VA at 20V AC/DC and features epoxy sealed terminals with a polyamide actuator. The GT12MCKE is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GT12MCKE is determined by strict equivalence across the following electrical and mechanical parameters:

Circuit configuration must remain SPST with On-Off functionality. Current and voltage ratings must match or exceed the original specification of 0.4VA at 20V AC/DC. Mounting type, termination style, and through-hole configuration must be identical. Actuator type, length, and material composition must be preserved. Operating temperature range and electrical life must meet or exceed the original ratings. The substitute part must originate from the same manufacturer series (GT) to ensure mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The GT12MCBE serves as the direct substitute for the obsolete GT12MCKE. Both components are electrically and mechanically identical across all critical parameters: SPST circuit configuration, 0.4VA current rating, 20V AC/DC voltage rating, through-hole mounting with PC pin termination, and identical actuator specifications.

The primary distinction between the two parts is product status and regulatory compliance. The GT12MCBE is currently in active production status, ensuring long-term availability and supply chain continuity. The GT12MCBE achieves ROHS3 compliance, whereas the GT12MCKE is non-compliant. For applications subject to RoHS regulations or requiring compliance documentation, the GT12MCBE is the appropriate selection. The GT12MCBE is REACH Affected, indicating it has undergone REACH substance evaluation, whereas the GT12MCKE is REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can GT12MCBE directly replace GT12MCKE in existing designs?

A: Yes. The GT12MCBE is electrically and mechanically equivalent to the GT12MCKE across all specified parameters, including circuit configuration, current and voltage ratings, mounting type, termination style, and actuator specifications. Direct substitution is supported without design modification.

Q: What is the primary reason to transition from GT12MCKE to GT12MCBE?

A: The GT12MCKE is obsolete and no longer in production. The GT12MCBE is the active production equivalent from the same manufacturer series, ensuring continued availability and supply chain support. Additionally, the GT12MCBE meets ROHS3 compliance requirements.

Q: Are there packaging differences between GT12MCKE and GT12MCBE?

A: The GT12MCKE is supplied in standard packaging, while the GT12MCBE is supplied in bulk packaging. Both configurations contain identical components; packaging format does not affect electrical or mechanical performance.

Q: What compliance certifications apply to each part?

A: The GT12MCKE is RoHS non-compliant and REACH Unaffected. The GT12MCBE is ROHS3 compliant and REACH Affected. For applications requiring RoHS compliance, the GT12MCBE is the appropriate selection.

Q: Are the electrical ratings identical between the two parts?

A: Yes. Both the GT12MCKE and GT12MCBE are rated for 0.4VA at 20V AC/DC with identical operating temperature ranges (-30°C to 85°C) and electrical life (40,000 cycles).
