Electroswitch D2C0405N Rotary Switch - Equivalent & Substitute Parts

Part Overview

The Electroswitch D2C0405N is a panel-mount rotary switch featuring 2 to 5 adjustable positions with dual-deck configuration (DP5T circuit). Rated for 250mA AC at 115V and 550mA DC at 28V, this non-shorting contact switch is designed for applications requiring reliable position selection with solder lug termination. The part is Active status and RoHS Compliant, with 1,077 units currently in stock.

Substitute parts are identified when equivalent electrical ratings, mechanical mounting specifications, and contact configurations are maintained within the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

The D2D0406N is identified as a substitute based on the following alignment criteria:

Maintained Parameters:

• Manufacturer: Electroswitch (same family)
• Series: D2 (same product line)
• Current Rating: 250mA (AC), 550mA (DC) — identical
• Voltage Rating: 115V (AC), 28V (DC) — identical
• Contact Timing: Non-Shorting (BBM) — identical
• Contact Material & Finish: Brass with Silver — identical
• Mounting Type: Panel Mount — identical
• Termination Style: Solder Lug — identical
• RoHS Status: RoHS Compliant — identical
• Product Status: Active — identical

Differing Parameters:

• Number of Positions: D2C0405N supports 2~5 positions; D2D0406N supports 2~6 positions
• Circuit Configuration: D2C0405N is DP5T; D2D0406N is DP6T
• Actuator Diameter: D2C0405N uses 3.17mm; D2D0406N uses 6.35mm
• Panel Cutout Dimensions: D2C0405N requires 6.76mm circular; D2D0406N requires 9.78mm circular
• Depth Behind Panel: D2C0405N is 18.14mm; D2D0406N is 18.34mm

Substitution is valid when the application requires up to 6 positions instead of 5, and the mechanical installation parameters (larger actuator diameter and panel cutout) are accommodated in the design.

Parameter Comparison

Engineering Selection Recommendations

Both D2C0405N and D2D0406N are Active status components with RoHS Compliance and identical electrical ratings (250mA AC / 550mA DC at 115V AC / 28V DC). Selection between these parts depends on application-specific requirements:

Select D2C0405N when:

• Application requires up to 5 selectable positions
• Panel cutout is sized for 6.76mm diameter
• Actuator diameter of 3.17mm is specified in mechanical design

Select D2D0406N when:

• Application requires up to 6 selectable positions
• Panel cutout can accommodate 9.78mm diameter
• Actuator diameter of 6.35mm is compatible with control interface design
• Extended position range provides design flexibility

Both parts maintain identical electrical performance, contact characteristics, and compliance certifications. Mechanical integration parameters (panel cutout and actuator diameter) are the primary selection criteria.

Frequently Asked Questions (FAQ)

Q: Can D2D0406N replace D2C0405N in existing designs?

A: Electrical substitution is valid. However, mechanical redesign is required: the panel cutout must be enlarged from 6.76mm to 9.78mm diameter, and the actuator interface must accommodate the larger 6.35mm diameter shaft. Depth behind panel difference (18.14mm vs 18.34mm) is negligible.

Q: What is the key difference between DP5T and DP6T configurations?

A: DP5T (D2C0405N) provides 5 contact positions per deck; DP6T (D2D0406N) provides 6 contact positions per deck. The additional position in D2D0406N allows one additional switch state in the application circuit.

Q: Are the current and voltage ratings identical?

A: Yes. Both parts are rated for 250mA AC at 115V and 550mA DC at 28V. Electrical load capacity is equivalent.

Q: What does "Non-Shorting (BBM)" contact timing mean?

A: BBM (Break-Before-Make) contact timing ensures that the previous contact position breaks before the new position makes contact. This prevents momentary short circuits during position transitions and is maintained in both parts.

Q: Are both parts RoHS Compliant?

A: Yes. Both D2C0405N and D2D0406N are RoHS Compliant and Active status, suitable for applications with environmental compliance requirements.

Q: What is the inventory status for each part?

A: D2C0405N has 1,077 units in stock; D2D0406N has 756 units in stock. Both are available for immediate procurement.
