DA08BTV Equivalent & Substitute Parts

Part Overview

The DA08BTV is an 8-position DIP slide switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications. This SPST (Single Pole Single Throw) switch operates at 24VDC with a 50mA current rating and features gold-plated phosphor bronze contacts. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA08BTV is determined by the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Number of Positions: 8-position requirement
• Voltage Rating: 24VDC operation
• Mounting Type: Through hole, right-angle configuration
• Pitch and Physical Footprint: 0.100" (2.54mm) pitch with compatible board height
• Actuator Type: Slide (standard) actuator mechanism
• Contact Finish: Gold plating for signal integrity
• Compliance: ROHS3 compliance for regulatory alignment

The NDA-08T-V from APEM Inc. meets these core substitution criteria. While the current rating differs (25mA versus 50mA), this represents a derating condition acceptable for applications where the original 50mA specification exceeds actual circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDA-08T-V is the primary substitute for the obsolete DA08BTV. Selection is supported by the following factors:

• Active Product Status: The NDA-08T-V maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and safety requirements
• Functional Equivalence: Identical circuit topology, position count, voltage rating, mounting configuration, and pitch ensure direct PCB compatibility without layout modifications
• Current Rating Consideration: The reduced current rating (25mA versus 50mA) is acceptable for applications where circuit current draw does not exceed 25mA. Applications requiring the full 50mA specification must evaluate alternative suppliers or higher-rated switch families

Frequently Asked Questions (FAQ)

Q: Can the NDA-08T-V be used as a direct replacement for the DA08BTV without PCB modifications?

A: Yes. Both parts share identical mounting type (through hole, right angle), pitch (0.100"), height above board (0.390"), and actuator configuration. No PCB layout changes are required.

Q: What is the significance of the current rating difference between these parts?

A: The DA08BTV is rated for 50mA while the NDA-08T-V is rated for 25mA. The substitute part operates at a lower current specification. Applications must confirm that actual circuit current does not exceed 25mA. If higher current capacity is required, alternative switch families must be evaluated.

Q: Are there compatibility concerns with the contact material specification?

A: The DA08BTV specifies phosphor bronze contacts with gold finish. The NDA-08T-V specifies gold finish without detailed contact material documentation. Both maintain gold plating for signal integrity. Contact material differences do not affect electrical performance in standard 24VDC switching applications.

Q: How does the obsolete status of the DA08BTV affect component selection?

A: The DA08BTV is no longer manufactured. The NDA-08T-V, with active product status, provides a supported alternative for new designs and ongoing system maintenance. Existing inventory of the DA08BTV may be available through authorized distributors, but long-term procurement should transition to the NDA-08T-V.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the DA08BTV and NDA-08T-V operate across -20°C to 70°C, ensuring compatibility in equivalent thermal environments.
