DA04KV Equivalent & Substitute Parts

Part Overview

The DA04KV is a DIP slide switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 4 positions. It is rated for 50mA at 24VDC and features a through-hole, right-angle mounting with raised slide actuator. The DA04KV is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA04KV is determined by the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 4
• Voltage Rating: Must be 24VDC
• Actuator Type & Level: Must be Slide (Standard) with Raised level
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Height Above Board: Must be 0.390" (9.90mm)
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must support -20°C to 70°C
• RoHS & MSL Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The NDA-04-V meets all critical substitution criteria. The primary difference is a reduced current rating (25mA versus 50mA), which represents a design constraint rather than an incompatibility. This substitution is valid for applications where the circuit current requirement does not exceed 25mA.

Parameter Comparison

Engineering Selection Recommendations

The NDA-04-V is the active production equivalent for the obsolete DA04KV. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical interfaces, with the exception of current rating capacity.

Selection of the NDA-04-V is appropriate when:

• The application circuit current requirement does not exceed 25mA
• Procurement of active production components is required
• ROHS3 compliance and MSL 1 rating are mandatory
• Mechanical and thermal operating parameters align with the -20°C to 70°C range

If the application requires the full 50mA current capacity of the original DA04KV, alternative components with equivalent mechanical form factors and higher current ratings must be evaluated from the APEM Inc. product portfolio or other qualified manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the NDA-04-V be used as a direct replacement for the DA04KV?

A: The NDA-04-V is mechanically and electrically compatible with the DA04KV for applications where circuit current does not exceed 25mA. Both components share identical mounting type, pitch, height above board, and operating temperature range. Verification that your application current requirement is within the 25mA limit is required before substitution.

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

A: The current rating differs: DA04KV is rated for 50mA, while NDA-04-V is rated for 25mA. All other electrical and mechanical parameters are equivalent.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance differences exist between the two parts.

Q: Why is the DA04KV obsolete?

A: The DA04KV has been discontinued by APEM Inc. The NDA-04-V represents the active production alternative within the same product family.

Q: Will the NDA-04-V fit in the same PCB footprint as the DA04KV?

A: Yes. Both components have identical through-hole, right-angle mounting configuration with 0.100" (2.54mm) pitch and 0.390" (9.90mm) height above board. PCB layout compatibility is maintained.

Q: What should I do if my application requires 50mA current capacity?

A: Consult the APEM Inc. product catalog for alternative DIP switch models with equivalent mechanical form factors and 50mA or higher current ratings, or evaluate qualified substitutes from other manufacturers meeting the same mechanical and electrical interface specifications.
