ADTS65KV Equivalent & Substitute Parts

Part Overview

The ADTS65KV is an SPST-NO tactile switch manufactured by APEM Inc., designed for through-hole mounting applications requiring low-current switching at 12VDC. This Active product features a standard polyamide actuator with tactile feedback, 9.50mm vertical height, and 0.25mm switch travel. The part is RoHS3 compliant and MSL 1 rated, suitable for general-purpose switching applications with moderate operating force requirements.

Substitute parts are identified when equivalent circuit topology, mounting configuration, and electrical ratings support direct replacement in the application, with consideration for mechanical and environmental parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADTS65KV are qualified based on the following substitution criteria:

Primary Compatibility Requirements:

• Circuit configuration: SPST-NO (maintained across all substitutes)
• Switch function: Off-Mom (momentary operation)
• Mounting type: Through Hole with PC Pin termination
• Actuator orientation: Top Actuated
• Contact rating: 0.05A minimum at rated voltage

Allowable Parameter Variations:

• Voltage rating: Substitutes rated at 32VDC exceed the 12VDC requirement and are acceptable for lower-voltage applications
• Actuator height: Substitutes at 9.90mm represent a 0.40mm increase, within typical PCB layout tolerance
• Outline dimensions: Substitutes at 7.40mm x 7.40mm represent a 1.20mm increase in footprint
• Operating force: Substitutes range from 130gf to 500gf, representing variations in actuation feel
• Switch travel: Substitutes range from 0.50mm to 0.70mm, representing increased tactile displacement
• Operating temperature: Substitutes rated to -40°C ~ 90°C provide extended environmental range
• Mechanical life: Substitutes rated from 500,000 to 1,000,000 cycles exceed typical requirements

All substitute parts are RoHS3 compliant, MSL 1 rated, and Active products from C&K (KSL MKII series).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and RoHS3 compliance, ensuring regulatory continuity and supply chain stability. The C&K KSL MKII series substitutes provide enhanced environmental protection through IP65 ingress rating, extending application scope to moisture-sensitive environments beyond the ADTS65KV capability.

KSL0M212LFT offers the closest mechanical profile match with 130gf operating force and 500,000-cycle mechanical life, suitable for applications requiring minimal footprint increase and standard actuation feel.

KSL0M312LFT provides the highest mechanical life rating at 1,000,000 cycles with equivalent 130gf operating force, appropriate for high-cycle-count applications requiring extended component longevity.

KSL0M412LFT and KSL0M512LFT feature increased operating forces (300gf and 500gf respectively) with reduced mechanical life ratings (100,000 cycles), suitable for applications requiring higher actuation resistance or tactile feedback emphasis.

All substitutes operate at 32VDC, exceeding the 12VDC requirement and providing margin for voltage transient conditions. Extended temperature range (-40°C ~ 90°C) accommodates broader environmental specifications than the original part.

Frequently Asked Questions (FAQ)

Q: Can KSL0M212LFT, KSL0M312LFT, KSL0M412LFT, or KSL0M512LFT directly replace ADTS65KV in a 12VDC circuit?

A: Yes. All substitute parts are rated for 0.05A @ 32VDC, which exceeds the 12VDC requirement. The SPST-NO circuit configuration, Off-Mom function, and through-hole PC pin termination are identical. Electrical compatibility is confirmed.

Q: What are the mechanical differences between ADTS65KV and the KSL MKII substitutes?

A: The primary mechanical differences are actuator height (9.50mm vs. 9.90mm), outline footprint (6.20mm x 6.20mm vs. 7.40mm x 7.40mm), and switch travel (0.25mm vs. 0.50-0.70mm). Operating force varies from 130gf to 500gf across the KSL MKII series, compared to 100gf for ADTS65KV. These variations require PCB layout verification and user interface feel assessment.

Q: Which substitute part should be selected for maximum mechanical life?

A: KSL0M312LFT provides the highest mechanical life rating at 1,000,000 cycles, compared to 500,000 cycles for KSL0M212LFT and 100,000 cycles for KSL0M412LFT and KSL0M512LFT.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ADTS65KV and all four KSL MKII substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the advantage of IP65 ingress protection in the KSL MKII series?

A: IP65 rating provides dust-tight and water-resistant protection, enabling use in environments with moisture exposure or particulate contamination. ADTS65KV does not specify ingress protection, limiting application scope to controlled environments.

Q: Do the substitute parts fit the same PCB footprint as ADTS65KV?

A: No. The KSL MKII series has a larger outline (7.40mm x 7.40mm vs. 6.20mm x 6.20mm) and increased actuator height (9.90mm vs. 9.50mm). PCB layout and enclosure clearance must be re-evaluated before substitution.
