DA10T DIP Switch SPST 10 Position Equivalent & Substitute Parts

Part Overview

The DA10T is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 10 positions. This component is rated for 50mA at 24VDC and features through-hole, right-angle mounting with gold-plated phosphor bronze contacts. The DA10T is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DA10T is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 10-position requirement
• Mounting Interface: Through-hole, right-angle configuration with 0.100" (2.54mm) pitch
• Voltage Rating: 24VDC minimum
• Actuator Type: Slide-actuated mechanism
• Contact Finish: Gold plating for reliability

The DA10T operates at 50mA. Substitute parts rated at 25mA represent a reduced current capability and are suitable only for applications where the actual load current does not exceed 25mA. The NDA-10T-V and KAS2110E both meet the core mechanical and electrical interface requirements while maintaining ROHS3 compliance and 24VDC voltage rating.

Parameter Comparison

Engineering Selection Recommendations

NDA-10T-V (APEM Inc.): This substitute maintains APEM Inc. manufacturer continuity and is classified as active product status. It is suitable for applications where the circuit load current does not exceed 25mA. The NDA-10T-V shares identical mechanical dimensions, pitch, and mounting interface with the DA10T. ROHS3 compliance and MSL 1 rating are maintained.

KAS2110E (E-Switch): This substitute is manufactured by E-Switch and carries active product status. It provides a wider operating temperature range (-40°C ~ 85°C) compared to the DA10T (-20°C ~ 70°C), offering enhanced thermal performance for extended environmental applications. Like the NDA-10T-V, the KAS2110E is rated at 25mA and requires load current verification. Mechanical compatibility is confirmed through identical pitch, mounting type, and height above board specifications. ROHS3 compliance and MSL 1 rating are maintained.

Both substitutes are suitable for direct PCB footprint replacement when application current requirements do not exceed 25mA.

Frequently Asked Questions (FAQ)

Q: Can the NDA-10T-V or KAS2110E be used as direct replacements for the DA10T?

A: Both parts are mechanically and electrically compatible for direct PCB footprint replacement. However, the current rating reduction from 50mA to 25mA must be evaluated against actual circuit load requirements. If the application circuit draws more than 25mA, these substitutes are not suitable.

Q: What is the primary difference between the NDA-10T-V and KAS2110E?

A: Both parts share identical electrical ratings (25mA, 24VDC) and mechanical dimensions. The KAS2110E offers an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) and is supplied in tube packaging rather than standard packaging. The KAS2110E is manufactured by E-Switch rather than APEM Inc.

Q: Are all three parts ROHS3 compliant?

A: Yes. The DA10T, NDA-10T-V, and KAS2110E are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the pitch specification, and why is it important?

A: All three parts feature a 0.100" (2.54mm) pitch, which defines the center-to-center spacing of the switch positions. This specification ensures mechanical and electrical compatibility with existing PCB layouts designed for the DA10T.

Q: Does the washable feature affect substitution compatibility?

A: The DA10T is washable with epoxy sealed terminals and tape seal. The NDA-10T-V is washable with tape seal. The KAS2110E is not washable. Washability is a secondary feature and does not affect electrical or mechanical substitution compatibility unless the application specifically requires post-assembly cleaning processes.
