DA07BT DIP Switch SPST 7 Position Equivalent & Substitute Parts

Part Overview

The DA07BT 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 DA07BT is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA07BT is determined by the following critical parameters:

• Circuit configuration (SPST)
• Number of positions (7)
• Voltage rating (24VDC)
• Mounting type (Through Hole, Right Angle)
• Pitch spacing (0.100" / 2.54mm)
• Height above board (0.390" / 9.90mm)
• Actuator type (Slide, Standard)
• Contact finish (Gold)
• Operating temperature range (-20°C to 70°C)

The NDA-07T-V qualifies as a substitute based on matching all critical mechanical and electrical parameters. The primary difference is a reduced current rating (25mA versus 50mA), which represents a derating that maintains compatibility for applications within the lower current specification.

Parameter Comparison

Engineering Selection Recommendations

The NDA-07T-V is suitable as a substitute for the DA07BT in applications where the circuit current requirement does not exceed 25mA. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The NDA-07T-V carries active product status, providing superior long-term availability and supply chain stability compared to the obsolete DA07BT.

Selection of the NDA-07T-V requires confirmation that the application circuit operates within the 25mA maximum current specification. Mechanical compatibility is assured through identical mounting geometry, pitch spacing, and height above board dimensions.

Frequently Asked Questions (FAQ)

Q: Can the NDA-07T-V directly replace the DA07BT in existing designs?

A: Direct replacement is possible if the application circuit current does not exceed 25mA. The mechanical footprint, mounting type, and electrical interface are identical. If the original design requires the full 50mA current rating, the NDA-07T-V is not suitable.

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

A: The current rating differs: DA07BT is rated for 50mA, while NDA-07T-V is rated for 25mA. All other electrical and mechanical specifications remain equivalent.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Why is the DA07BT obsolete?

A: The DA07BT is classified as obsolete by the manufacturer. The NDA-07T-V represents the active product line continuation from APEM Inc. for this switch category.

Q: Will the NDA-07T-V fit the same PCB footprint?

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

Q: What is the electrical life expectancy for the NDA-07T-V?

A: The NDA-07T-V is rated for 2,000 electrical cycles, matching the DA07BT specification.
