KSC223G Equivalent & Substitute Parts

Part Overview

The KSC223G is a tactile switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.01A at 32VDC. This surface mount component features top actuation, gull wing termination, and IP67 ingress protection suitable for dust-tight and waterproof applications. The KSC223G is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC223G is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.01A @ 32VDC
• Mounting type: Surface Mount
• Actuator height: 4.60mm
• Outline dimensions: 6.20mm x 6.20mm
• Operating force: 160gf
• Ingress protection: IP67
• Operating temperature range: -40°C to 125°C
• Switch travel: 0.35mm
• Mechanical life: 500,000 Cycles
• Termination style: Gull Wing
• Actuator orientation: Top Actuated

The KSC223GLFG meets all these parameters and is classified as an active product within the same KSC series, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The KSC223GLFG is the direct substitute for the obsolete KSC223G. Both components share identical electrical and mechanical specifications across all critical parameters. The primary differences are product status and compliance certifications:

The KSC223GLFG is an active product with ROHS3 compliance, whereas the KSC223G is obsolete and RoHS non-compliant. For new designs or ongoing production requiring RoHS compliance, the KSC223GLFG is the appropriate selection. The packaging difference (Tape & Reel versus bulk) reflects standard distribution formats for active versus legacy products and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can KSC223GLFG replace KSC223G in existing designs?

A: Yes. The KSC223GLFG is functionally identical to the KSC223G across all electrical and mechanical parameters, including circuit configuration, contact rating, actuator dimensions, operating force, ingress protection, temperature range, and mechanical life. Direct substitution is supported without design modification.

Q: What is the difference between KSC223G and KSC223GLFG?

A: The primary differences are product status and compliance. The KSC223G is obsolete and RoHS non-compliant, while the KSC223GLFG is an active product with ROHS3 compliance. Packaging differs (bulk versus Tape & Reel), but electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of KSC223GLFG affect compatibility?

A: No. Packaging format does not affect component functionality or performance. Tape & Reel packaging is standard for active production items and is compatible with automated assembly processes.

Q: Are there RoHS compliance implications for using KSC223G?

A: The KSC223G is RoHS non-compliant. For applications requiring RoHS compliance, the KSC223GLFG (ROHS3 compliant) must be used.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (SPST-NO), contact rating (0.01A @ 32VDC), mounting type (Surface Mount), actuator dimensions (4.60mm height, 6.20mm x 6.20mm outline), operating force (160gf), ingress protection (IP67), temperature range (-40°C to 125°C), switch travel (0.35mm), mechanical life (500,000 cycles), and termination style (Gull Wing).
