KSC141G Equivalent & Substitute Parts

Part Overview

The KSC141G 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 KSC141G is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSC141G is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Mounting type (Surface Mount)
• Physical outline (6.20mm x 6.20mm)
• Actuator height (2.50mm)
• Actuator orientation (Top Actuated)
• Termination style (Gull Wing)
• Operating force (300gf)
• Switch travel (0.30mm)
• Ingress protection (IP67)
• Operating temperature range (-40°C ~ 85°C)
• Mechanical life (200,000 Cycles)

The KSC141GLFS meets all these parameters and is therefore a direct functional equivalent. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The KSC141GLFS is the direct substitute for the obsolete KSC141G. Both parts are functionally identical across all electrical and mechanical parameters. The KSC141GLFS offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance meets current regulatory requirements, whereas the KSC141G is RoHS non-compliant
• Tape & Reel packaging is standard for automated assembly processes and high-volume production

For new designs or production transitions, the KSC141GLFS is the appropriate selection. For legacy system repairs requiring exact part matching, the KSC141G remains functionally equivalent where regulatory compliance is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can KSC141GLFS be used as a direct replacement for KSC141G in existing designs?

A: Yes. The KSC141GLFS is electrically and mechanically identical to the KSC141G. All functional parameters, including circuit configuration, contact rating, physical dimensions, actuator specifications, and operating characteristics, are equivalent. The primary differences are product status and packaging format.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (KSC141G) is suitable for manual handling and small-quantity applications. Tape & Reel packaging (KSC141GLFS) is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Both packaging formats contain the same component.

Q: Why is RoHS compliance important for this substitution?

A: The KSC141GLFS is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components. The KSC141G is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the KSC141GLFS is the required selection.

Q: Are there any performance differences between KSC141G and KSC141GLFS?

A: No. Both parts share identical electrical performance, mechanical characteristics, and reliability specifications. Operating force, switch travel, mechanical life, ingress protection, and temperature range are equivalent.

Q: What inventory considerations apply to this substitution?

A: The KSC141G is obsolete with limited remaining inventory. The KSC141GLFS is an active product with established supply chain availability. For ongoing production requirements, the KSC141GLFS is the recommended selection to ensure supply continuity.
