DA05 DIP Switch SPST Equivalent & Substitute Parts

Part Overview

The DA05 is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 5 positions. This component is rated for 50mA at 24VDC and features through-hole, right-angle mounting with gold-plated phosphor bronze contacts. The DA05 is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA05 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 5
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Slide (Standard)
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Height Above Board: Must be 0.390" (9.90mm)
• Contact Finish: Must be Gold
• Operating Temperature Range: Must support -20°C to 70°C
• RoHS Compliance: Must be ROHS3 Compliant

The NDA-05-V meets all critical substitution parameters. The primary difference is the current rating: the NDA-05-V is rated for 25mA versus the DA05's 50mA. This represents a reduction in maximum current capacity and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDA-05-V is an active product from APEM Inc. and provides direct substitution for the obsolete DA05 across all mechanical and electrical interface parameters. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary consideration for component selection is current rating. The NDA-05-V supports 25mA maximum current versus the DA05's 50mA rating. Selection of the NDA-05-V is appropriate when circuit current requirements do not exceed 25mA. If the application requires current capacity above 25mA, alternative components from the active APEM product line must be evaluated.

Both components share identical mechanical footprints, pitch spacing, and mounting orientation, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the NDA-05-V directly replace the DA05 in existing designs?

A: Mechanical and electrical interface compatibility is confirmed. The NDA-05-V maintains identical pitch (0.100"), height above board (0.390"), mounting type (through hole, right angle), and voltage rating (24VDC). Substitution is valid provided circuit current requirements do not exceed 25mA.

Q: What is the primary difference between these components?

A: The NDA-05-V is rated for 25mA maximum current, while the DA05 is rated for 50mA. All other electrical and mechanical parameters are equivalent.

Q: Are there compliance differences between the DA05 and NDA-05-V?

A: Both components are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical (MSL 1, Unlimited). No compliance barriers exist for substitution.

Q: Does the NDA-05-V require PCB layout modifications?

A: No. Identical pitch spacing (0.100"), mounting type (through hole, right angle), and height above board (0.390") ensure direct footprint compatibility without layout changes.

Q: What is the product status difference?

A: The DA05 is classified as obsolete, while the NDA-05-V is active. The NDA-05-V is currently manufactured and available for procurement.
