ADTS63SV Equivalent & Substitute Parts

Part Overview

The ADTS63SV is an active tactile switch manufactured by APEM Inc., classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.05A at 12VDC. This component is designed for applications requiring momentary switching with tactile feedback. The part is currently in active production status with 1,081 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across different manufacturers while meeting the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADTS63SV is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO
• Contact Rating: Must support 0.05A @ 12VDC minimum
• Mounting Type: Must be Through Hole
• Actuator Orientation: Must be Top Actuated
• Termination Style: Must be PC Pin
• Switch Function: Must be Off-Mom (Momentary)
• Compliance: Must maintain ROHS3 compliance

The TL1240RQ1JCLR from E-Switch meets these core electrical and mechanical requirements, making it a valid substitute for the ADTS63SV in applications where the specified parameters are met.

Parameter Comparison

Engineering Selection Recommendations

Both the ADTS63SV and TL1240RQ1JCLR are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The primary selection criteria are:

ADTS63SV is the preferred choice when:

• Non-illuminated operation is required
• Operating temperature must reach -25°C
• Compact outline dimensions are critical
• Lower actuator height is necessary for space-constrained applications

TL1240RQ1JCLR is suitable when:

• Visual feedback through LED illumination is required
• Operating temperature minimum of -20°C is acceptable
• Additional 1.20mm outline dimension variation is accommodated in PCB layout
• Additional 1.20mm actuator height is compatible with enclosure design
• LED illumination power supply (2.3VDC nominal) can be integrated into the circuit

Both parts maintain identical electrical performance at 0.05A @ 12VDC and share the same switch travel distance of 0.25mm.

Frequently Asked Questions (FAQ)

Q: Can TL1240RQ1JCLR directly replace ADTS63SV without PCB modification?

A: Direct replacement requires verification of three factors: (1) PCB footprint accommodation of the 6.00mm x 6.00mm outline versus the original 6.20mm x 6.20mm, (2) enclosure clearance for the 8.20mm actuator height versus the original 7.00mm, and (3) circuit integration of the LED illumination feature if not required for the application.

Q: What is the impact of the operating temperature range difference?

A: The ADTS63SV operates from -25°C to 70°C, while the TL1240RQ1JCLR operates from -20°C to 70°C. If the application requires operation below -20°C, the ADTS63SV must be used. For applications within the -20°C to 70°C range, both parts are functionally equivalent.

Q: Does the LED illumination in TL1240RQ1JCLR affect electrical compatibility?

A: The LED illumination operates at 2.3VDC nominal and is independent of the switch contact circuit. If the application does not require illumination, the LED can remain unpowered without affecting switch operation. However, circuit design must accommodate the LED pins if the illumination feature is not utilized.

Q: Are the mechanical life specifications equivalent?

A: The ADTS63SV does not specify mechanical life in the provided data. The TL1240RQ1JCLR specifies 100,000 cycles. For applications requiring documented mechanical life specifications, the TL1240RQ1JCLR provides this assurance.

Q: What are the key parameters that must remain constant for substitution?

A: The following parameters must be identical for valid substitution: SPST-NO circuit configuration, 0.05A @ 12VDC contact rating, Off-Mom switch function, Through Hole mounting, Top Actuated orientation, PC Pin termination, and 0.25mm switch travel. Variations in outline dimensions, actuator height, operating temperature range, and illumination features require design review but do not prevent substitution if mechanical and thermal constraints are satisfied.
