KSA1M210 Equivalent & Substitute Parts

Part Overview

The KSA1M210 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 a grounding pin for enhanced circuit protection. The product is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Contact current rating: 0.05A minimum
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• Switch travel: 0.50mm

Allowable Variation Parameters:

• Contact voltage rating: May be equal to or exceed 32VDC
• Actuator height: ±0.50mm tolerance acceptable for PCB layout compatibility
• Operating force: Variance permitted within application requirements
• Operating temperature: Must encompass -40°C minimum
• Mechanical life: May exceed 100,000 cycles

The substitute parts listed below meet all mandatory criteria while offering improved specifications in voltage rating, mechanical durability, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - TL6105AF160QP (E-Switch)

This part provides the closest electrical match to the KSA1M210. The contact voltage rating of 50VDC exceeds the original 32VDC specification, ensuring full compatibility in existing circuit designs. The TL6105AF160QP maintains identical actuator height (4.70mm) and switch travel (0.50mm), requiring no PCB layout modifications. As an active product with ROHS3 compliance and grounding pin feature, it represents the optimal choice for direct replacement in new production runs.

Secondary Substitutes - TL6100AF130QP, TL6100AF160QP, TL6100AF300QP (E-Switch)

These TL6100 series alternatives are suitable for applications where voltage requirements do not exceed 12VDC. All three maintain the 4.70mm actuator height and 0.50mm switch travel, ensuring mechanical compatibility. The TL6100AF130QP matches the original 130gf operating force, while TL6100AF160QP and TL6100AF300QP offer increased operating force options. These parts feature superior mechanical life ratings (500,000 to 1,000,000 cycles) and ROHS3 compliance. Selection among these three depends on specific force requirements and cycle life expectations.

Alternative Substitute - TL6100BF300RP (E-Switch)

This variant differs in actuator height (5.20mm versus 4.70mm), introducing a 0.50mm vertical offset. Use this part only when PCB layout accommodates the increased height or when the application specifically requires 300gf operating force with the TL6100 series characteristics. ROHS3 compliance and 500,000 cycle mechanical life are maintained.

Voltage Consideration

Applications operating at voltages below 12VDC may use TL6100 series parts without derating. Applications requiring the full 32VDC rating must use TL6105AF160QP exclusively.

Frequently Asked Questions (FAQ)

Q: Can TL6100 series switches replace KSA1M210 in 32VDC circuits?

A: No. TL6100 series parts are rated for 12VDC maximum. For 32VDC applications, use TL6105AF160QP, which is rated for 50VDC and maintains full compatibility with the original KSA1M210 specifications.

Q: What is the significance of the actuator height difference in TL6100BF300RP?

A: The TL6100BF300RP has a 5.20mm actuator height compared to the standard 4.70mm. This 0.50mm difference may affect PCB clearance and user interface feel. Verify PCB layout compatibility before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed E-Switch substitutes are ROHS3 compliant, whereas the original KSA1M210 is RoHS non-compliant. This compliance improvement is beneficial for modern manufacturing and regulatory requirements.

Q: How do operating force variations affect circuit performance?

A: Operating force (measured in grams-force) determines the tactile feedback and actuation pressure required. The KSA1M210 specifies 130gf. Substitutes with higher operating force (160gf, 300gf) require greater finger pressure but may reduce accidental actuation. Lower force values are not available among the listed substitutes.

Q: What is the difference between switch travel specifications?

A: Switch travel indicates the distance the actuator moves before electrical contact occurs. The KSA1M210 and most substitutes feature 0.50mm travel. TL6105AF160QP has 0.25mm travel, resulting in faster response but potentially different tactile characteristics. This parameter does not affect electrical compatibility.

Q: Can I use TL6100 series parts in applications requiring grounding pin functionality?

A: TL6100AF130QP, TL6100AF160QP, and TL6100AF300QP do not specify grounding pin features. TL6105AF160QP includes grounding pin and sealed construction, making it the appropriate choice when grounding functionality is required.

Q: What inventory considerations apply to these substitutes?

A: All listed substitutes are currently in active production with substantial inventory availability. TL6105AF160QP has the lowest stock level (647 pcs), while TL6100 series variants exceed 4,700 pcs. For high-volume requirements, verify current availability with the supplier.
