ADTS61SV Equivalent & Substitute Parts

Part Overview

The ADTS61SV is an APEM Inc. tactile switch featuring SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration with momentary off operation. This through-hole mounted component is rated for 0.05A at 12VDC and delivers tactile feedback with a 320gf operating force. The part is Active status and ROHS3 compliant, making it suitable for standard industrial and consumer applications requiring reliable tactile switching.

Substitute parts become necessary when addressing application requirements such as higher voltage ratings, enhanced environmental protection, extended temperature ranges, or improved mechanical durability specifications that exceed the original ADTS61SV parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADTS61SV is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit Configuration: SPST-NO (all substitutes maintain this requirement)
• Mounting Type: Through Hole (all substitutes maintain this requirement)
• Actuator Orientation: Top Actuated (all substitutes maintain this requirement)
• Outline Dimensions: 6.20mm x 6.20mm (all substitutes maintain this requirement)
• Termination Style: PC Pin (all substitutes maintain this requirement)
• Switch Function: Off-Mom momentary operation (all substitutes maintain this requirement)

Allowable Variation Parameters:

• Contact Rating Voltage: Substitutes rated at 32VDC exceed the 12VDC requirement and remain compatible
• Contact Rating Current: Substitutes rated at 0.01A are acceptable where 0.05A is specified, as lower current ratings indicate more conservative switching capability
• Operating Force: Ranges from 130gf to 300gf; variations accommodate different tactile feedback requirements
• Actuator Height: 4.70mm substitutes exceed the 4.30mm specification within acceptable mechanical tolerances
• Switch Travel: 0.50mm to 0.60mm variations remain within functional parameters
• Operating Temperature: Extended ranges (-40°C ~ 125°C) provide broader environmental compatibility
• Ingress Protection: IP65 rating on substitutes provides enhanced environmental sealing beyond the original specification
• Mechanical Life: Rated cycles (100,000 to 1,000,000) indicate durability improvements

All substitute parts are manufactured by C&K (KSA MKII series), maintain Active product status, and are ROHS3 compliant with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All four C&K KSA MKII series substitutes maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original ADTS61SV specification.

KSA0M212LFT provides direct electrical compatibility with 0.05A current rating while offering enhanced voltage margin (32VDC vs. 12VDC) and IP65 environmental sealing. Mechanical life is rated at 100,000 cycles. This substitute is suitable for applications requiring higher voltage tolerance and dust/water resistance without extended temperature requirements.

KSA0M312LFT maintains 0.05A current rating with 32VDC voltage capability and IP65 protection. Mechanical life specification reaches 1,000,000 cycles, representing a tenfold improvement in durability. Operating temperature extends to -40°C ~ 85°C. This substitute addresses applications demanding extended mechanical life and moderate environmental protection.

KSA0M332LFT operates at reduced current rating (0.01A @ 32VDC) with extended operating temperature range (-40°C ~ 125°C) and 1,000,000 cycle mechanical life. IP65 ingress protection is included. This substitute is appropriate for low-current signal switching applications requiring broad temperature operation and enhanced environmental sealing.

KSA0M432LFT features 0.01A current rating at 32VDC with operating force of 300gf (matching the original ADTS61SV) and extended temperature range (-40°C ~ 125°C). Mechanical life is rated at 100,000 cycles with IP65 protection. This substitute provides tactile feedback consistency with the original part while enabling low-current applications across wider temperature extremes.

Frequently Asked Questions (FAQ)

Q: Can KSA0M212LFT, KSA0M312LFT, KSA0M332LFT, or KSA0M432LFT be used as direct replacements for ADTS61SV in existing PCB designs?

A: Yes. All substitute parts maintain identical outline dimensions (6.20mm x 6.20mm), through-hole mounting configuration, PC pin termination, and top-actuated orientation. PCB footprints and mechanical mounting are compatible. Actuator height increases from 4.30mm to 4.70mm; verify clearance in your enclosure design.

Q: What is the primary difference between KSA0M212LFT and KSA0M312LFT?

A: Both parts share identical electrical ratings (0.05A @ 32VDC), dimensions, and environmental protection (IP65). The critical distinction is mechanical life: KSA0M212LFT is rated for 100,000 cycles while KSA0M312LFT reaches 1,000,000 cycles. Select KSA0M312LFT for applications with high actuation frequency requirements.

Q: When should I select KSA0M332LFT or KSA0M432LFT instead of the 0.05A rated alternatives?

A: These parts are specified for applications switching currents of 0.01A or lower. If your circuit operates at 0.05A, the higher-rated KSA0M212LFT or KSA0M312LFT are appropriate. The 0.01A variants provide conservative margin for low-signal switching applications such as logic-level control or sensor inputs.

Q: Does the increased actuator height (4.70mm vs. 4.30mm) affect functionality?

A: The 0.40mm height increase does not affect electrical function or tactile performance. Verify that your enclosure or overlay design accommodates the taller actuator profile. The switch travel and operating force characteristics remain within acceptable parameters for standard tactile switch applications.

Q: Are all substitute parts environmentally sealed?

A: Yes. All four C&K KSA MKII substitutes feature IP65 ingress protection (dust tight, water resistant), exceeding the original ADTS61SV specification. This enhancement provides improved reliability in applications exposed to moisture or particulate contamination.

Q: What is the temperature operating range difference, and when is it critical?

A: The original ADTS61SV operates from -25°C to 70°C. KSA0M212LFT and KSA0M312LFT extend to -40°C ~ 85°C. KSA0M332LFT and KSA0M432LFT reach -40°C ~ 125°C. Select extended-range variants for applications in extreme thermal environments, such as automotive underhood, industrial furnace controls, or arctic/desert field equipment.

Q: How do operating force specifications affect switch selection?

A: ADTS61SV specifies 320gf operating force. KSA0M212LFT, KSA0M312LFT, and KSA0M332LFT provide 130gf (lighter actuation), while KSA0M432LFT matches the original 300gf. Select based on tactile feedback preference and user interface requirements. Lighter force (130gf) reduces finger fatigue in high-frequency applications; higher force (300gf) provides positive tactile confirmation.

Q: Are all parts available in bulk packaging?

A: Yes. All parts listed are supplied in bulk packaging. Current inventory levels are: ADTS61SV (890 pcs), KSA0M212LFT (5,539 pcs), KSA0M312LFT (1,901 pcs), KSA0M332LFT (4,678 pcs), and KSA0M432LFT (12,201 pcs).
