KSC201J Equivalent & Substitute Parts

Part Overview

The KSC201J is a tactile switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 32VDC. This surface mount component features top actuation, IP67 ingress protection, and is designed for applications requiring reliable tactile feedback with minimal travel distance. The KSC201J is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC201J is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, KSC201JLFS, maintains identical specifications across all critical functional parameters: circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), mounting type (surface mount), physical dimensions (6.20mm x 6.20mm), actuator height (4.60mm), operating force (160gf), switch travel (0.30mm), ingress protection (IP67), operating temperature range (-40°C ~ 85°C), mechanical life (5,000,000 cycles), and termination style (J Lead).

The substitution is valid based on these matching parameters. The KSC201JLFS differs from the KSC201J in product status (active versus obsolete) and RoHS compliance status (ROHS3 Compliant versus non-compliant), with packaging offered as Cut Tape and Digi-Reel formats.

Parameter Comparison

Engineering Selection Recommendations

The KSC201JLFS is the direct functional equivalent of the KSC201J and serves as the primary substitute for applications requiring replacement or new production. Selection of KSC201JLFS is supported by its active product status, ensuring continued availability and supply chain reliability. The KSC201JLFS carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in regulated markets. Both parts maintain identical electrical and mechanical specifications, ensuring drop-in compatibility in existing PCB designs without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can KSC201JLFS be used as a direct replacement for KSC201J in existing designs?
