ES02MCKE Equivalent & Substitute Parts

Part Overview

The ES02MCKE is a slide switch manufactured by C&K, classified as a SPST (Single Pole Single Throw) switch rated for 0.4VA at 20V. This component features through-hole mounting with epoxy sealed terminals and IP57 protection. The part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The ES02MCBE qualifies as a direct substitute for the ES02MCKE based on matching electrical and mechanical parameters. Both parts share identical circuit configuration (SPST), current rating (0.4VA AC/DC), voltage ratings (20V AC/DC), switch travel (2.29mm), actuator length (3.07mm), operating temperature range (-30°C to 85°C), mechanical and electrical life ratings (40,000 cycles each), mounting type (through hole), termination style (PC pin), contact finish (gold), and protective features (epoxy sealed terminals, IP57).

The substitution is valid across the following critical parameters:

• Electrical specifications (voltage and current ratings)
• Mechanical dimensions (actuator length and switch travel)
• Environmental performance (temperature range, sealing)
• Durability metrics (mechanical and electrical life cycles)
• Physical interface (mounting and termination compatibility)

Parameter Comparison

Engineering Selection Recommendations

The ES02MCBE is the appropriate substitute for the obsolete ES02MCKE. Both components are manufactured by C&K within the same ES series and maintain identical electrical and mechanical specifications. The ES02MCBE offers the additional advantage of active product status, ensuring continued availability and supply chain support.

For applications requiring RoHS3 compliance, the ES02MCBE is the mandated choice, as the ES02MCKE does not meet RoHS requirements. The ES02MCBE is supplied in tray packaging, which may differ from the original part's packaging configuration and should be evaluated for assembly line compatibility.

Frequently Asked Questions (FAQ)

Q: Can ES02MCBE directly replace ES02MCKE in existing designs? A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), mechanical dimensions (3.07mm actuator length, 2.29mm travel), mounting configuration (through hole, PC pin termination), and environmental specifications (-30°C to 85°C operating range). Physical and functional compatibility is confirmed.

Q: What is the primary reason for substitution? A: The ES02MCKE is obsolete. The ES02MCBE provides equivalent functionality with active product status and improved compliance (ROHS3).

Q: Are there packaging differences between these parts? A: The ES02MCKE packaging is unspecified in available documentation. The ES02MCBE is supplied in tray packaging. Verify tray configuration compatibility with your assembly process before procurement.

Q: Do both parts meet the same environmental and durability standards? A: Yes. Both components feature epoxy sealed terminals with IP57 protection, operate across -30°C to 85°C, and are rated for 40,000 mechanical and electrical cycles.

Q: Which part should be selected for new designs? A: The ES02MCBE should be selected for new designs due to active product status and ROHS3 compliance certification.
