ADTS61YV Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The ADTS61YV is an active SPST-NO (Single Pole Single Throw - Normally Open) tactile switch manufactured by APEM Inc. in the ADTS series. This through-hole mounted component is rated for 0.05A at 12VDC with a top-actuated standard actuator and tactile feedback. The part is ROHS3 compliant and currently in active production with 740 units in stock.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and circuit function can be maintained across different voltage ratings, operating force specifications, and temperature ranges while preserving the core SPST-NO switching architecture and through-hole PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Mounting type: Through Hole
• Termination style: PC Pin
• Outline dimensions: 6.20mm x 6.20mm
• Actuator orientation: Top Actuated

Allowable Variation Parameters:

• Contact rating voltage: May exceed 12VDC (higher voltage rating is backward compatible)
• Contact rating current: Must meet or exceed 0.05A requirement
• Operating force: May vary within mechanical design constraints
• Actuator height: Minor variations acceptable within PCB clearance tolerances
• Switch travel: May vary based on actuator design
• Operating temperature range: May be wider than -25°C ~ 70°C
• Mechanical life: Specification provided where available

All substitute parts listed (KSA0M212LFT, KSA0M312LFT, KSA0M332LFT, KSA0M432LFT, KSA0M512LFT) are manufactured by C&K in the KSA MKII series and meet the mandatory compatibility parameters. Variations in contact rating current (0.01A vs 0.05A), operating force (130gf to 500gf), and temperature range reflect design differences within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.

For applications requiring 0.05A contact current at rated voltage: KSA0M212LFT, KSA0M512LFT, and KSA0M312LFT support the 0.05A current requirement. KSA0M512LFT provides the closest operating force match (500gf vs 520gf) with extended temperature range (-40°C ~ 85°C). KSA0M212LFT offers the lowest operating force (130gf) with the same current rating.

For applications with reduced current requirements (0.01A): KSA0M332LFT and KSA0M432LFT are rated for 0.01A at 32VDC. KSA0M332LFT provides extended temperature operation (-40°C ~ 125°C) with 1,000,000 cycle mechanical life. KSA0M432LFT offers higher operating force (300gf) with 100,000 cycle life.

For applications requiring extended temperature operation: KSA0M332LFT and KSA0M432LFT both support -40°C ~ 125°C operating range, exceeding the ADTS61YV specification of -25°C ~ 70°C.

For applications requiring enhanced environmental protection: All KSA MKII series substitutes provide IP65 ingress protection (dust tight, water resistant), whereas the ADTS61YV does not specify ingress protection.

Frequently Asked Questions (FAQ)

Q: Can KSA0M332LFT or KSA0M432LFT be used as direct replacements if my application only requires 0.01A?

A: Yes, if your circuit design operates at 0.01A or lower current levels. These parts are rated for 0.01A @ 32VDC and maintain identical SPST-NO circuit configuration, through-hole mounting, and PC pin termination. Verify that your PCB layout accommodates the 4.70mm actuator height (0.40mm taller than ADTS61YV).

Q: What is the impact of different operating force values?

A: Operating force determines the tactile feedback and actuation pressure required. ADTS61YV requires 520gf, while KSA MKII substitutes range from 130gf to 500gf. Lower operating force (130gf) requires less finger pressure; higher force (500gf) provides firmer tactile response. Select based on user interface requirements and mechanical design constraints.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All parts share identical 6.20mm x 6.20mm outline dimensions and PC pin termination. However, actuator height varies: ADTS61YV is 4.30mm while all KSA MKII substitutes are 4.70mm. Verify PCB clearance above the switch to accommodate the 0.40mm height difference.

Q: What is the significance of the voltage rating difference (12VDC vs 32VDC)?

A: All substitute parts are rated for 32VDC, which exceeds the ADTS61YV 12VDC rating. A higher voltage rating indicates the switch can safely operate in circuits with higher voltage potential without risk of arcing or contact degradation. This provides design flexibility for applications operating at voltages between 12VDC and 32VDC.

Q: Which substitute offers the best mechanical durability?

A: KSA0M312LFT and KSA0M332LFT both specify 1,000,000 cycle mechanical life, compared to 100,000 cycles for KSA0M212LFT, KSA0M432LFT, and KSA0M512LFT. The ADTS61YV does not specify mechanical life. Select based on expected actuation frequency over the product lifetime.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. MSL Level 1 (Unlimited) rating applies to all parts, indicating no moisture sensitivity restrictions during storage or assembly.
