ADTS61RV Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The ADTS61RV 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 standard actuator providing tactile feedback. The switch features a 4.30mm actuator height, 6.20mm x 6.20mm outline, and polyamide actuator material with 260gf operating force.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer offerings. Alternative models may be required due to component availability, supply chain considerations, or design optimization for specific operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADTS61RV is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary)
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• Outline dimensions: 6.20mm x 6.20mm
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Secondary Consideration Parameters:

• Contact rating voltage: Minimum 12VDC (higher voltage ratings are acceptable)
• Contact rating current: Minimum 0.05A (higher current ratings are acceptable)
• Actuator height: Nominal 4.30mm (±0.40mm variance acceptable for through-hole PCB mounting)
• Operating temperature range: Minimum -25°C ~ 70°C coverage
• MSL rating: 1 (Unlimited)

The five substitute parts identified (KSA0M212LFT, KSA0M312LFT, KSA0M332LFT, KSA0M432LFT, KSA0M512LFT) from C&K's KSA MKII series maintain identical circuit topology, mounting configuration, and mechanical footprint. All substitutes exceed the voltage and current specifications of the ADTS61RV and provide enhanced environmental protection (IP65 rating) and extended mechanical life ratings.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the ADTS61RV. The KSA MKII series substitutes provide enhanced specifications across multiple parameters:

Voltage and Current Ratings: All C&K substitutes are rated for 32VDC, exceeding the ADTS61RV's 12VDC specification. Current ratings of 0.05A (KSA0M212LFT, KSA0M512LFT) and 0.01A (KSA0M332LFT, KSA0M432LFT) accommodate the original 0.05A requirement.

Environmental Protection: The KSA MKII series provides IP65 ingress protection (dust tight, water resistant), offering enhanced durability compared to the unspecified ingress protection of the ADTS61RV.

Temperature Performance: KSA0M332LFT and KSA0M432LFT extend the upper operating temperature to 125°C, while KSA0M212LFT and KSA0M512LFT maintain -40°C to 85°C coverage, both exceeding the ADTS61RV's -25°C to 70°C range.

Mechanical Characteristics: Actuator height variance (4.70mm vs. 4.30mm) represents a 0.40mm increase, acceptable for through-hole PCB mounting applications. Operating force ranges from 130gf to 500gf, providing selection flexibility for different tactile feedback requirements. Mechanical life ratings of 100,000 to 1,000,000 cycles exceed the unspecified rating of the original part.

Frequently Asked Questions (FAQ)

Q: Can KSA MKII series switches directly replace the ADTS61RV in existing PCB designs?

A: Yes, all identified substitutes maintain identical circuit topology (SPST-NO), mounting type (through hole), actuator orientation (top actuated), termination style (PC pin), and outline dimensions (6.20mm x 6.20mm). The 0.40mm increase in actuator height (4.70mm vs. 4.30mm) is within acceptable tolerance for through-hole applications and does not affect PCB compatibility.

Q: What are the key differences in electrical performance between the ADTS61RV and substitute parts?

A: The primary electrical difference is voltage rating. The ADTS61RV is rated for 12VDC, while all KSA MKII substitutes are rated for 32VDC. This higher voltage rating provides design margin and is fully backward compatible with 12VDC applications. Current ratings vary: KSA0M212LFT, KSA0M512LFT, and the original ADTS61RV all support 0.05A, while KSA0M332LFT and KSA0M432LFT are rated for 0.01A.

Q: Which substitute part should be selected for applications requiring maximum operating force?

A: KSA0M512LFT provides the highest operating force at 500gf, compared to the ADTS61RV's 260gf. KSA0M432LFT offers 300gf. KSA0M212LFT, KSA0M312LFT, and KSA0M332LFT provide 130gf, suitable for applications requiring lighter actuation.

Q: Are all substitute parts suitable for moisture-sensitive environments?

A: All parts, including the ADTS61RV and KSA MKII substitutes, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations. Additionally, the KSA MKII series provides IP65 ingress protection, offering enhanced environmental resistance in dust and moisture-prone applications.

Q: What is the mechanical life expectancy difference between the ADTS61RV and substitute parts?

A: The ADTS61RV does not specify mechanical life. KSA MKII substitutes provide rated mechanical life: KSA0M212LFT and KSA0M432LFT are rated for 100,000 cycles, while KSA0M312LFT and KSA0M332LFT are rated for 1,000,000 cycles. KSA0M512LFT is rated for 100,000 cycles.

Q: Do all substitute parts meet the same regulatory compliance standards as the ADTS61RV?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the ADTS61RV. Both the original part and all substitutes carry ECCN EAR99 and HTSUS 8536.50.9031 classifications.

Q: How does the switch travel specification affect substitution suitability?

A: The ADTS61RV has 0.25mm switch travel, while KSA MKII substitutes range from 0.50mm to 0.70mm. Increased switch travel provides greater tactile feedback and may improve reliability in applications with variable actuation force. This difference does not affect electrical compatibility but may influence user experience in manual actuation scenarios.
