DA07T DIP Switch SPST 7 Position Equivalent & Substitute Parts

Part Overview

The DA07T is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 7 positions. This component is rated for 50mA at 24VDC and features through-hole, right-angle mounting with gold-plated phosphor bronze contacts. The DA07T is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA07T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 7
• Voltage Rating: Must be 24VDC
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Height Above Board: Must be 0.390" (9.90mm)
• Actuator Type: Must be Slide (Standard)
• Contact Finish: Must be Gold

Current rating may vary within the operational envelope of the application. The DA07T operates at 50mA; substitute parts rated at 25mA are acceptable for applications not requiring the full 50mA capacity. All identified substitutes meet the core electrical and mechanical parameters required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

NDA-07T-V (APEM Inc.): This substitute maintains APEM Inc. as the original manufacturer and is classified as Active. It meets all core electrical and mechanical parameters. The current rating is reduced to 25mA; this part is suitable for applications where the load current does not exceed 25mA. Both parts carry ROHS3 compliance and identical MSL ratings.

KAS2107E (E-Switch): This substitute is manufactured by E-Switch and is classified as Active. It meets all core electrical and mechanical parameters and provides an extended operating temperature range (-40°C ~ 85°C) compared to the DA07T (-20°C ~ 70°C). The current rating is 25mA. This part carries ROHS3 compliance and identical MSL ratings. Packaging is supplied in Tube format.

Both substitutes are suitable for direct replacement in applications where the 25mA current rating is sufficient. Selection between NDA-07T-V and KAS2107E depends on manufacturer preference, temperature operating requirements, and packaging specifications.

Frequently Asked Questions (FAQ)

Q: Can the NDA-07T-V replace the DA07T in all applications?

A: The NDA-07T-V is a direct mechanical and electrical substitute provided the application current requirement does not exceed 25mA. Both parts share identical voltage rating, position count, mounting configuration, and pitch. The NDA-07T-V is manufactured by the same supplier (APEM Inc.) as the original DA07T.

Q: What is the primary difference between the KAS2107E and the DA07T?

A: The KAS2107E is manufactured by E-Switch rather than APEM Inc. and provides an extended operating temperature range of -40°C ~ 85°C versus the DA07T's -20°C ~ 70°C. The current rating is reduced to 25mA. All other electrical and mechanical parameters are equivalent. The KAS2107E is supplied in Tube packaging.

Q: Are there current rating limitations when substituting the DA07T?

A: Yes. The DA07T is rated for 50mA at 24VDC. Both identified substitutes (NDA-07T-V and KAS2107E) are rated for 25mA. Substitution is valid only for applications where the circuit current does not exceed 25mA. Applications requiring the full 50mA capacity cannot use these substitutes.

Q: Do all three parts meet RoHS compliance?

A: Yes. The DA07T, NDA-07T-V, and KAS2107E are all ROHS3 compliant. All three parts carry MSL rating of 1 (Unlimited) and are REACH Unaffected.

Q: What are the packaging differences?

A: The DA07T and NDA-07T-V packaging specifications are not explicitly defined in the available data. The KAS2107E is supplied in Tube packaging.
