KSC151G Equivalent & Substitute Parts

Part Overview

The KSC151G 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 KSC151G carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSC151G is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Mounting type (Surface Mount)
• Actuator orientation (Top Actuated)
• Termination style (Gull Wing)
• Outline dimensions (6.20mm x 6.20mm)
• Actuator height off PCB (2.50mm)
• Operating force (550gf)
• Switch travel (0.35mm)
• Ingress protection rating (IP67)
• Operating temperature range (-40°C ~ 85°C)
• Mechanical life (100,000 Cycles)
• Non-illuminated specification

The KSC151GLFS meets all these criteria and qualifies as a direct substitute for the KSC151G.

Parameter Comparison

Engineering Selection Recommendations

The KSC151GLFS is the direct substitute for the obsolete KSC151G. Both parts are manufactured by C&K and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The KSC151G is classified as obsolete, while the KSC151GLFS maintains active product status. Additionally, the KSC151GLFS is ROHS3 compliant, whereas the KSC151G is RoHS non-compliant. For new designs or systems requiring current regulatory alignment, the KSC151GLFS is the appropriate selection.

Both parts are available in standard packaging formats. The KSC151GLFS is supplied in Cut Tape (CT) packaging with significantly higher inventory availability (10,548 pieces) compared to the KSC151G (1,153 pieces).

Frequently Asked Questions (FAQ)

Q: Can the KSC151GLFS directly replace the KSC151G in existing designs?

A: Yes. The KSC151GLFS is electrically and mechanically identical to the KSC151G. All critical parameters including circuit configuration, contact rating, mounting type, actuator specifications, and environmental ratings are equivalent. Direct substitution is possible without design modification.

Q: What is the difference between KSC151G and KSC151GLFS?

A: The parts are functionally equivalent. The KSC151GLFS differs in product status (active versus obsolete) and regulatory compliance (ROHS3 compliant versus RoHS non-compliant). The KSC151GLFS also features Cut Tape packaging and higher inventory availability.

Q: Are there packaging differences between these parts?

A: The KSC151G packaging specification is not detailed in the available data. The KSC151GLFS is supplied in Cut Tape (CT) packaging. Confirm packaging requirements with your procurement or assembly team before finalizing component selection.

Q: What certifications apply to both parts?

A: Both the KSC151G and KSC151GLFS carry REACH Unaffected status and are classified under ECCN EAR99. The KSC151GLFS additionally meets ROHS3 compliance requirements. Both parts have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Are these parts suitable for IP67-rated applications?

A: Yes. Both parts provide IP67 ingress protection (dust tight and waterproof), making them suitable for sealed and wet environment applications within the specified operating temperature range of -40°C to 85°C.
