M2011SD3W02 Equivalent & Substitute Parts

Part Overview

The M2011SD3W02 is a toggle switch manufactured by NKK Switches, classified as a SPST (Single Pole Single Throw) panel mount switch with on-off functionality. This component features a standard round actuator with quick connect termination and is rated for 6A AC at 125V and 4A DC at 30V operation.

The M2011SD3W02 carries an obsolete product status. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design revisions require updated component specifications. The substitute part M2011SD3W01 provides functional equivalence with modified termination characteristics.

Substitute Part Grouping Explanation

Substitution of the M2011SD3W02 with the M2011SD3W01 is based on electrical and mechanical parameter equivalence within the NKK Switches M series toggle switch family. Both components share identical specifications across the following critical parameters:

• Circuit configuration (SPST)
• Current ratings (6A AC / 4A DC)
• Voltage ratings (125V AC / 30V DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Bushing thread specification (1/4-40)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (25,000 Cycles)
• Actuator type and length (Standard Round, 10.50mm)
• Actuator material (Brass, Chrome Plated)

The primary distinction between these parts lies in termination style: the M2011SD3W02 uses Quick Connect 0.062" (1.5mm) termination, while the M2011SD3W01 uses Solder Lug termination. This difference affects circuit board integration methodology but does not alter electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M2011SD3W01 serves as a direct functional substitute for the M2011SD3W02 based on electrical and mechanical parameter equivalence. Both components are classified as obsolete products within the NKK Switches M series.

Selection between these two parts depends on circuit board integration requirements:

M2011SD3W02 (Quick Connect Termination): Suitable for applications utilizing quick connect receptacles on the circuit board or panel assembly. This termination style enables rapid insertion and removal without soldering.

M2011SD3W01 (Solder Lug Termination): Suitable for applications requiring permanent solder joint connections to the circuit board. This termination style provides fixed mechanical and electrical connection.

Both components meet RoHS compliance requirements, with M2011SD3W01 carrying the more recent ROHS3 designation. Both maintain identical electrical performance specifications and environmental ratings. The choice between these substitutes is determined solely by the termination interface available in the target application.

Frequently Asked Questions (FAQ)

Q: Can M2011SD3W01 replace M2011SD3W02 in existing designs?
