DA08BTN DIP Switch Equivalent & Substitute Parts

Part Overview

The DA08BTN is an 8-position DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications requiring SPST switching at 24VDC with a 50mA current rating. This component features phosphor bronze contacts with gold finish, epoxy sealed terminals, and a tape seal for environmental protection.

The DA08BTN is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DA08BTN must satisfy the following criteria to ensure functional and mechanical compatibility:

Critical Parameters for Substitution:

• Circuit configuration: SPST
• Number of positions: 8
• Voltage rating: 24VDC
• Mounting type: Through hole, right angle
• Pitch: 0.100" (2.54mm)
• Height above board: 0.390" (9.90mm)
• Actuator type: Slide (standard)

Allowable Variation:

• Current rating: The substitute part may have a lower current rating if the application does not require the full 50mA capacity of the original component. The NDA-08T-V operates at 25mA, which is suitable for applications with reduced current requirements.

The NDA-08T-V from APEM Inc. meets all critical substitution parameters and maintains compatibility with the original DA08BTN footprint and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

The NDA-08T-V is the appropriate substitute for the DA08BTN based on the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Product Availability: The NDA-08T-V carries an active product status with 696 units in stock, providing reliable supply chain access compared to the obsolete DA08BTN.

Functional Compatibility: The substitute maintains identical mechanical footprint, mounting configuration, pitch spacing, and height above board. The SPST circuit configuration, 8-position count, and 24VDC voltage rating remain unchanged.

Current Rating Consideration: The NDA-08T-V operates at 25mA versus the original 50mA rating. Selection of this substitute is appropriate for applications where the circuit current demand does not exceed 25mA. Applications requiring the full 50mA capacity of the original component require evaluation of alternative sources.

Frequently Asked Questions (FAQ)

Q: Can the NDA-08T-V directly replace the DA08BTN in existing PCB designs?

A: Yes, the NDA-08T-V maintains identical through-hole pitch (0.100"), height above board (0.390"), and right-angle mounting configuration. Direct PCB footprint compatibility is confirmed.

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

A: The current rating differs: DA08BTN is rated at 50mA, while NDA-08T-V is rated at 25mA. Both operate at 24VDC with identical switching characteristics and mechanical dimensions.

Q: Is the NDA-08T-V suitable for my application if the original design specified 50mA?

A: The NDA-08T-V is suitable only if the actual circuit current requirement does not exceed 25mA. If your application requires the full 50mA capacity, the substitute is not appropriate.

Q: Are there any differences in contact material or finish?

A: Both components feature gold-finished contacts. The DA08BTN specifies phosphor bronze contact material; the NDA-08T-V contact material is not specified in available documentation.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and rated for -20°C to 70°C operating temperature. Both feature MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the mechanical life difference between these components?

A: The DA08BTN specifies 5,000 mechanical cycles. The NDA-08T-V mechanical life specification is not provided in available documentation. Both specify 2,000 electrical cycles.
