KSA0M210 Equivalent & Substitute Parts

Part Overview

The KSA0M210 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 KSA0M210 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 KSA0M210 is determined by the following critical parameters that must remain consistent across equivalent parts:

Mandatory Compatibility Parameters:

• 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: Substitute parts rated at 12VDC are acceptable for applications originally specified at 32VDC, provided the actual operating voltage does not exceed the substitute part rating
• Actuator height: Variation within ±0.50mm is acceptable for PCB layout compatibility
• Outline dimensions: Minor variations (±0.20mm) are acceptable
• Operating force: Variations in operating force (130gf, 160gf, 300gf) represent different actuation characteristics and must be selected based on application requirements
• Mechanical life: Substitute parts with higher cycle ratings (1,000,000 or 500,000 cycles) exceed the original specification and are acceptable
• Operating temperature range: Substitute parts with -40°C ~ 85°C range are acceptable for applications within this envelope
• RoHS compliance: Active substitute parts with ROHS3 compliance are preferred for new designs

The E-Switch TL6100 series parts listed below meet the mandatory compatibility criteria and are qualified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL6100AF130QP

The TL6100AF130QP is the closest functional equivalent to the KSA0M210. It maintains identical operating force (130gf), actuator height (4.70mm), and switch travel (0.50mm). This part is currently in active production status with ROHS3 compliance, making it suitable for new designs and ongoing production support. The contact voltage rating of 12VDC is lower than the original 32VDC specification; applications must verify that actual operating voltages do not exceed 12VDC. Mechanical life is significantly improved at 1,000,000 cycles compared to the original 100,000 cycles.

Alternative Substitute: TL6100AF160QP

The TL6100AF160QP provides identical dimensional and electrical compatibility with a higher operating force of 160gf. This variant is appropriate for applications requiring increased actuation resistance. All other parameters remain consistent with TL6100AF130QP, including active product status and ROHS3 compliance.

High-Force Substitute: TL6100AF300QP

The TL6100AF300QP offers the highest operating force at 300gf with active product status and ROHS3 compliance. Mechanical life is rated at 500,000 cycles. This variant is suitable for applications requiring substantial actuation force. Outline dimensions remain 7.20mm x 7.20mm with 4.70mm actuator height.

Tall-Actuator Variant: TL6100BF300RP

The TL6100BF300RP is functionally equivalent to TL6100AF300QP with an increased actuator height of 5.20mm. This variant accommodates applications requiring extended actuator reach above the PCB surface. All other electrical and mechanical parameters remain consistent with the TL6100AF300QP.

Voltage Rating Consideration:

All E-Switch TL6100 series substitutes are rated at 12VDC maximum contact voltage, compared to the original KSA0M210 specification of 32VDC. Circuit designs must be evaluated to confirm that actual operating voltages remain within the 12VDC limit of the substitute parts. If the application requires operation above 12VDC, these substitutes are not appropriate.

Frequently Asked Questions (FAQ)

Q: Can the TL6100 series parts directly replace the KSA0M210 in existing designs?

A: Direct replacement is possible if the application operates at 12VDC or lower. The TL6100 series maintains identical circuit configuration (SPST-NO), switch function (Off-Mom), contact current rating (0.05A), mounting type (Through Hole), actuator orientation (Top Actuated), and termination style (PC Pin). PCB layout compatibility must be verified due to minor outline dimension differences (7.20mm vs. 7.40mm).

Q: What is the significance of the different operating force ratings (130gf, 160gf, 300gf)?

A: Operating force determines the tactile feedback and actuation resistance experienced by the user. The 130gf variant (TL6100AF130QP) matches the original KSA0M210 specification. The 160gf variant (TL6100AF160QP) provides moderate increase in actuation resistance. The 300gf variants (TL6100AF300QP and TL6100BF300RP) require substantially greater force to actuate and are suitable for applications where accidental activation must be prevented.

Q: Are there packaging differences between the substitute parts?

A: TL6100AF130QP, TL6100AF160QP, and TL6100AF300QP are supplied in Tube packaging. TL6100BF300RP packaging is not specified in the available data. Procurement requirements should be verified with the component supplier.

Q: What is the impact of the lower voltage rating on the TL6100 series?

A: The TL6100 series is rated at 0.05A @ 12VDC, compared to the KSA0M210 at 0.05A @ 32VDC. The lower voltage rating does not affect the current-carrying capability (both are 0.05A) but restricts the maximum voltage that can be safely applied across the switch contacts. Applications operating above 12VDC require alternative components.

Q: How do the mechanical life ratings compare?

A: The KSA0M210 is rated for 100,000 mechanical cycles. The TL6100AF130QP and TL6100AF160QP are rated for 1,000,000 cycles (10x improvement). The TL6100AF300QP and TL6100BF300RP are rated for 500,000 cycles (5x improvement). Higher cycle ratings indicate extended component longevity under repeated actuation.

Q: What is the difference between TL6100AF300QP and TL6100BF300RP?

A: Both parts are functionally identical with 300gf operating force and 500,000 mechanical life cycles. The primary difference is actuator height: TL6100AF300QP has 4.70mm height, while TL6100BF300RP has 5.20mm height. The taller actuator of the BF variant may be required for applications with specific PCB clearance or user interface requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. All E-Switch TL6100 series substitutes are ROHS3 compliant. The original KSA0M210 is RoHS non-compliant. For new designs subject to RoHS requirements, the TL6100 series substitutes are appropriate selections.

Q: What are the outline dimension differences?

A: The KSA0M210 has outline dimensions of 7.40mm x 7.40mm. All TL6100 series substitutes have outline dimensions of 7.20mm x 7.20mm. This 0.20mm reduction in each dimension is within typical PCB layout tolerances but should be verified in the specific application to confirm adequate clearance and mounting compatibility.
