DA10TN DIP Switch Equivalent & Substitute Parts

Part Overview

The DA10TN is a 10-position DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with a 50mA current rating at 24VDC. This component features a slide actuator with raised level, through-hole right-angle mounting, and gold-plated phosphor bronze contacts. The DA10TN is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA10TN is determined by the following critical parameters:

• Circuit Configuration: Must be SPST to maintain identical switching logic
• Number of Positions: Must be 10 to ensure pin-for-pin compatibility
• Voltage Rating: Must be 24VDC or higher to support the operating voltage
• Current Rating: Must be equal to or greater than 50mA to handle the design load
• Mounting Type: Must be through-hole, right-angle to fit the PCB layout
• Pitch: Must be 0.100" (2.54mm) for footprint compatibility
• Height Above Board: Must be 0.390" (9.90mm) or less to avoid mechanical interference
• Actuator Type: Must be slide (standard) to maintain user interface consistency

The NDA-10T-V from APEM Inc. meets the core electrical and mechanical requirements for substitution, with the exception of current rating, which is specified at 25mA versus the DA10TN's 50mA rating.

Parameter Comparison

Engineering Selection Recommendations

The NDA-10T-V qualifies as a functional substitute for the DA10TN based on electrical and mechanical compatibility. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The NDA-10T-V carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete DA10TN.

The primary design consideration is the reduced current rating of the NDA-10T-V (25mA versus 50mA). This substitution is valid only for applications where the actual circuit current does not exceed 25mA. For applications requiring the full 50mA capacity of the original DA10TN, alternative parts with equivalent or higher current ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the NDA-10T-V directly replace the DA10TN in existing designs?

A: Pin-for-pin and footprint compatibility is confirmed. Substitution is valid provided the circuit current requirement does not exceed 25mA. If the design draws more than 25mA, the NDA-10T-V will not provide adequate current capacity.

Q: What is the primary difference between these two parts?

A: The current rating differs. The DA10TN is rated for 50mA, while the NDA-10T-V is rated for 25mA. All other electrical and mechanical parameters are equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the DA10TN and NDA-10T-V are ROHS3 compliant and REACH unaffected.

Q: Why is the DA10TN listed as obsolete?

A: The DA10TN has been discontinued by APEM Inc. The NDA-10T-V represents the active product line continuation with equivalent functionality.

Q: Will the NDA-10T-V fit the same PCB footprint?

A: Yes. Both components share identical mounting specifications: through-hole right-angle configuration, 0.100" (2.54mm) pitch, and 0.390" (9.90mm) height above board.

Q: What operating temperature range do these switches support?

A: Both the DA10TN and NDA-10T-V operate across -20°C to 70°C.
