KSA0M410 Equivalent & Substitute Parts

Part Overview

The KSA0M410 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 component features top actuation, through-hole mounting, and is designed for applications requiring momentary switching functionality. The KSA0M410 is currently listed as obsolete, making identification of equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSA0M410 is determined by the following critical parameters:

Electrical Compatibility:

• Circuit configuration must remain SPST-NO
• Switch function must be Off-Mom (momentary)
• Contact rating current capacity: 0.05A minimum
• Voltage rating: substitute parts must support the application voltage requirement

Mechanical Compatibility:

• Mounting type: Through Hole (required for PCB compatibility)
• Actuator orientation: Top Actuated (required for accessibility and assembly)
• Termination style: PC Pin (required for through-hole assembly)
• Outline dimensions: 7.20mm x 7.20mm to 7.40mm x 7.40mm (acceptable tolerance for footprint compatibility)
• Actuator height: 4.70mm to 5.20mm (acceptable range for clearance and tactile feedback)

Operational Parameters:

• Operating force: 130gf to 300gf (determines tactile feedback and user experience)
• Switch travel: 0.50mm to 0.60mm (acceptable range for actuation distance)
• Operating temperature: minimum -40°C ~ 85°C (covers the KSA0M410 range)

The E-Switch TL6100 series parts listed below meet these substitution criteria across all electrical and mechanical parameters.

Engineering Selection Recommendations

For Direct Replacement with Matching Operating Force (300gf):

TL6100AF300QP and TL6100BF300RP are the primary substitutes for the KSA0M410. Both maintain the 300gf operating force specification, ensuring equivalent tactile feedback. TL6100AF300QP features a 4.70mm actuator height matching the original part, while TL6100BF300RP has a 5.20mm height. Both are active products with ROHS3 compliance and superior mechanical life ratings (500,000 cycles versus 100,000 cycles).

For Lower Operating Force Applications (130gf or 160gf):

TL6100AF130QP and TL6100AF160QP provide lighter actuation forces suitable for applications where reduced operating force is acceptable. These parts offer extended mechanical life (1,000,000 cycles) and maintain all other mechanical and electrical compatibility parameters.

Voltage Rating Consideration:

All E-Switch TL6100 series substitutes are rated at 0.05A @ 12VDC, compared to the KSA0M410 rating of 0.05A @ 32VDC. For applications operating at voltages exceeding 12VDC, design verification is required to confirm the substitute part meets the circuit voltage requirements.

Compliance Status:

All E-Switch TL6100 series parts are ROHS3 compliant and active products, providing long-term availability and supply chain stability compared to the obsolete KSA0M410.

Frequently Asked Questions (FAQ)

Q: Can TL6100 series parts directly replace the KSA0M410 in existing designs?

A: TL6100 series parts are mechanically and electrically compatible for through-hole PCB assembly. The outline dimensions (7.20mm x 7.20mm versus 7.40mm x 7.40mm) and actuator heights (4.70mm to 5.20mm) fall within acceptable tolerances for footprint compatibility. However, voltage rating differences (12VDC versus 32VDC) require circuit verification for applications exceeding 12V operation.

Q: What is the difference between TL6100AF300QP and TL6100BF300RP?

A: Both parts share identical electrical specifications and 300gf operating force. The primary difference is actuator height: TL6100AF300QP has 4.70mm height (matching the KSA0M410), while TL6100BF300RP has 5.20mm height. Selection depends on PCB clearance requirements and desired tactile feedback profile.

Q: Why do the TL6100 substitutes have lower voltage ratings than the KSA0M410?

A: The KSA0M410 is rated at 32VDC while TL6100 series parts are rated at 12VDC. This reflects different design specifications between manufacturers. Applications requiring operation above 12VDC must verify that the substitute part meets circuit voltage requirements before implementation.

Q: Which substitute part should I select if operating force is not critical?

A: TL6100AF130QP offers the lowest operating force (130gf) with the highest mechanical life rating (1,000,000 cycles), providing extended component longevity. TL6100AF160QP provides a mid-range option at 160gf with equivalent cycle life. Selection depends on user interface requirements and tactile feedback preferences.

Q: Are all TL6100 substitutes available in the same packaging as the KSA0M410?

A: TL6100AF130QP, TL6100AF160QP, and TL6100AF300QP are supplied in Tube packaging. TL6100BF300RP packaging is not specified in available data. Verify packaging requirements with your procurement process before finalizing part selection.

Q: What is the mechanical life advantage of TL6100 series parts?

A: The KSA0M410 is rated for 100,000 cycles. TL6100AF130QP and TL6100AF160QP provide 1,000,000 cycles (10x improvement), while TL6100AF300QP and TL6100BF300RP provide 500,000 cycles (5x improvement). Extended mechanical life reduces replacement frequency in high-cycle applications.
