KSC223J Equivalent & Substitute Parts

Part Overview

The KSC223J 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, IP67 ingress protection, and is designed for applications requiring reliable tactile feedback with minimal travel distance. The KSC223J 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 eligibility for the KSC223J is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to serve as a direct substitute:

• 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)
• Switch travel (0.35mm)
• Ingress protection rating (IP67)
• Operating temperature range (-40°C to 125°C)
• Mechanical life (500,000 Cycles)
• Termination style (J Lead)

The KSC223JLFG meets all these criteria and is classified as a direct substitute. Differences in packaging format and product status do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The KSC223JLFG is the direct functional equivalent of the KSC223J. Both components share identical electrical specifications, mechanical dimensions, and performance characteristics. The primary distinction lies in product status and regulatory compliance.

The KSC223J is classified as obsolete, indicating discontinued manufacturing and limited availability. The KSC223JLFG maintains active product status with current manufacturing support and availability.

From a compliance perspective, the KSC223JLFG carries ROHS3 certification, whereas the KSC223J is RoHS non-compliant. For applications subject to RoHS regulations, the KSC223JLFG is the appropriate selection. Both components maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

For new designs or production requiring this switch specification, the KSC223JLFG is the recommended selection based on active product status and regulatory compliance. For legacy system maintenance where the original KSC223J is required, the KSC223JLFG provides full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can KSC223JLFG replace KSC223J in existing designs?

A: Yes. The KSC223JLFG is electrically and mechanically identical to the KSC223J. All critical parameters including contact rating, dimensions, operating force, and temperature range are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between KSC223J and KSC223JLFG?

A: The components are functionally identical. Differences include product status (KSC223J is obsolete; KSC223JLFG is active), RoHS compliance (KSC223JLFG is ROHS3 compliant), and packaging format (KSC223JLFG is supplied in Cut Tape).

Q: Does packaging format affect compatibility?

A: No. Packaging format (Cut Tape versus standard) does not affect component functionality or performance. The difference is in supply and handling logistics only.

Q: Are there any electrical parameter differences?

A: No. Both parts maintain identical contact ratings of 0.01A @ 32VDC, circuit configuration (SPST-NO), and all electrical specifications.

Q: Which part should be selected for new production?

A: The KSC223JLFG should be selected for new production due to active product status, current manufacturing availability, and ROHS3 compliance.

Q: Is the KSC223J still available?

A: The KSC223J is classified as obsolete. Availability is limited to existing inventory. The KSC223JLFG is the recommended active alternative with current supply.
