KSC241G Equivalent & Substitute Parts

Part Overview

The KSC241G 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, gull wing termination, and IP67 ingress protection suitable for dust-tight and waterproof applications. The KSC241G is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSC241G is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Surface mount packaging with gull wing termination
• Physical footprint (6.20mm x 6.20mm outline)
• Actuator height (4.60mm vertical)
• Top actuation orientation
• Operating force (350gf)
• Switch travel (0.50mm)
• Ingress protection rating (IP67)
• Operating temperature range (-40°C ~ 85°C)
• Mechanical life specification (300,000 cycles)

The KSC241GLFS meets all these parameters and is therefore a direct functional equivalent. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The KSC241GLFS is the direct substitute for the obsolete KSC241G. Both components are electrically and mechanically identical across all functional parameters. The KSC241GLFS offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the KSC241GLFS carries ROHS3 compliance, whereas the KSC241G is non-compliant. For new designs or ongoing production requiring RoHS compliance, the KSC241GLFS is the appropriate selection. Both components maintain identical moisture sensitivity levels and regulatory classifications (REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Are KSC241G and KSC241GLFS electrically interchangeable?

A: Yes. Both components share identical circuit configuration (SPST-NO), contact rating (0.05A @ 32VDC), operating force (350gf), switch travel (0.50mm), and mechanical life (300,000 cycles). Electrical performance is equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both components have identical outline dimensions (6.20mm x 6.20mm), actuator height (4.60mm), and termination style (gull wing). PCB footprints are identical, requiring no layout modifications.

Q: What is the primary difference between these parts?

A: The KSC241G is obsolete, while the KSC241GLFS is active. The KSC241GLFS also carries ROHS3 compliance certification, whereas the KSC241G does not. Functionally, they are equivalent.

Q: Can I use KSC241GLFS in place of KSC241G in existing designs?

A: Yes. The KSC241GLFS is a direct functional replacement with no design modifications required. The identical mechanical and electrical specifications ensure compatibility.

Q: What packaging is available for KSC241GLFS?

A: The KSC241GLFS is supplied in Cut Tape (CT) packaging.

Q: Are there any compliance or regulatory differences?

A: The KSC241GLFS is ROHS3 compliant, while the KSC241G is not. Both maintain REACH Unaffected status and EAR99 classification. For applications requiring RoHS compliance, the KSC241GLFS is the appropriate selection.
