A23K1V-DA Equivalent & Substitute Parts

Part Overview

The A23K1V-DA is an active DPDT rocker switch manufactured by NKK Switches, rated for 0.4VA at 28V AC/DC. This through-hole, right-angle vertical mount switch features a concave black actuator with PC pin termination and is sealed for environmental protection. The component is ROHS3 compliant and carries CSA and UL approvals. Substitute parts are identified when equivalent electrical ratings, mechanical configurations, and circuit topologies are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A23K1V-DA are identified based on the following critical parameters that determine functional equivalence:

Circuit topology (DPDT configuration), mounting method (through-hole, right-angle, vertical orientation), actuator style (concave curved design), termination type (PC pin), and color (black). The substitute part 400MDP3R1BLKM7QE from E-Switch shares these core mechanical and electrical interface characteristics, enabling direct physical and functional replacement in applications where the electrical ratings permit.

The 400MDP3R1BLKM7QE operates at higher current (3A) and voltage (120V AC) ratings compared to the A23K1V-DA (0.4VA, 28V). This higher rating capability means the E-Switch part can be used in applications requiring the A23K1V-DA specifications, as the substitute exceeds the original part's electrical envelope. However, the substitute features an On-Off-On switch function versus the original On-On function, and exhibits lower mechanical and electrical life cycles (30,000 cycles each versus 100,000 and 50,000 respectively).

Parameter Comparison

Engineering Selection Recommendations

Both the A23K1V-DA and 400MDP3R1BLKM7QE are active products with current manufacturing status and regulatory compliance. The A23K1V-DA carries CSA and UL approvals, while the 400MDP3R1BLKM7QE carries cULus certification. Both components are ROHS3 compliant and rated for the same operating temperature range (-30°C to 85°C).

Selection between these parts depends on application-specific requirements. The A23K1V-DA is suitable for low-power 28V circuits requiring extended mechanical and electrical life. The 400MDP3R1BLKM7QE accommodates higher-power applications up to 120V AC and 3A, though with reduced cycle life ratings. The difference in switch function (On-On versus On-Off-On) must align with circuit design requirements. Both parts share identical mechanical mounting interfaces and physical form factors, supporting direct substitution where electrical specifications permit.

Frequently Asked Questions (FAQ)

Q: Can the 400MDP3R1BLKM7QE directly replace the A23K1V-DA in all applications?

A: Physical and mechanical compatibility is confirmed through matching mounting type, actuator style, termination, and form factor. Electrical compatibility requires verification that the application circuit operates within the substitute part's ratings. The higher current and voltage ratings of the 400MDP3R1BLKM7QE support applications designed for the A23K1V-DA. However, the different switch function (On-Off-On versus On-On) must be evaluated against circuit requirements.

Q: What are the key differences in electrical ratings?

A: The A23K1V-DA is rated for 0.4VA at 28V AC/DC. The 400MDP3R1BLKM7QE is rated for 3A at 120V AC and 28V DC. The substitute part exceeds the original specifications, making it suitable for higher-power applications while remaining compatible with lower-power circuits.

Q: How do the mechanical life ratings compare?

A: The A23K1V-DA specifies 100,000 mechanical cycles and 50,000 electrical cycles. The 400MDP3R1BLKM7QE specifies 30,000 cycles for both mechanical and electrical life. Applications requiring extended cycle life should prioritize the A23K1V-DA.

Q: Are both parts RoHS compliant?

A: Yes, both the A23K1V-DA and 400MDP3R1BLKM7QE are ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What certifications do these parts carry?

A: The A23K1V-DA carries CSA and UL approvals. The 400MDP3R1BLKM7QE carries cULus certification. Both certifications are recognized for industrial and commercial applications.
