Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC201G is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 32VDC)
• Physical mounting type (Surface Mount)
• Actuator orientation (Top Actuated)
• Termination style (Gull Wing)
• Outline dimensions (6.20mm x 6.20mm)
• Actuator height (4.60mm)
• Operating force (160gf)
• Switch travel (0.30mm)
• Ingress protection rating (IP67)
• Operating temperature range (-40°C to 85°C)
• Mechanical life (5,000,000 Cycles)
• Moisture sensitivity level (MSL 1)

The KSC201GLFS meets all these criteria and is classified as a direct substitute for the obsolete KSC201G.

Parameter Comparison

Engineering Selection Recommendations

The KSC201GLFS is the direct substitute for the obsolete KSC201G. Both components are electrically and mechanically identical across all specified parameters, ensuring pin-for-pin and functional compatibility.

The primary distinction between the two parts is product status and regulatory compliance. The KSC201G is obsolete and RoHS non-compliant, while the KSC201GLFS is an active product with ROHS3 compliance. For new designs or ongoing production requiring RoHS compliance, the KSC201GLFS is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can KSC201GLFS be used as a direct replacement for KSC201G?

A: Yes. The KSC201GLFS is electrically and mechanically identical to the KSC201G across all specified parameters, including circuit configuration, contact rating, physical dimensions, actuator characteristics, and environmental ratings. Direct substitution is supported without design modification.

Q: What is the difference between KSC201G and KSC201GLFS?

A: The primary differences are product status and regulatory compliance. The KSC201G is obsolete and RoHS non-compliant, while the KSC201GLFS is an active product with ROHS3 compliance. All electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: The KSC201G packaging is listed as standard, while the KSC201GLFS is supplied in Cut Tape (CT) packaging. Both formats are suitable for surface mount assembly processes.

Q: Does the RoHS3 compliance of KSC201GLFS affect performance?

A: No. RoHS3 compliance reflects material composition and environmental standards but does not alter electrical performance, mechanical characteristics, or functional behavior. The component operates identically to the KSC201G.

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

A: Yes. Both the KSC201G and KSC201GLFS maintain IP67 ingress protection (dust tight, waterproof) and are suitable for applications requiring this environmental rating.
