C&K 7201SPDWMES Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SPDWMES is a panel-mounted toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This switch features an anti-rotation brass actuator with chrome plating and wire wrap termination, designed for applications requiring reliable on-on switching functionality. The 7201SPDWMES is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7201SPDWMES is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Mechanical interface (Actuator type, length, panel cutout dimensions, bushing thread)
• Termination style (Wire Wrap)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (100,000 Cycles)

The C&K 7201SPDWSES meets all these criteria and qualifies as a direct substitute. The primary distinction between the main part and substitute is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SPDWSES is the appropriate substitute for the obsolete 7201SPDWMES. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs and panel assemblies.

The 7201SPDWSES offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 7201SPDWSES achieves RoHS compliance, making it suitable for applications subject to RoHS regulatory requirements. The REACH Affected status of the 7201SPDWSES indicates compliance with REACH substance restrictions.

Selection between these parts should be based on regulatory compliance requirements and supply availability. For new designs or systems requiring RoHS compliance, the 7201SPDWSES is the specified choice. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 7201SPDWSES directly replace the 7201SPDWMES in existing assemblies?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (DPDT), mechanical interface (panel cutout 6.35mm diameter, 1/4-40 bushing thread), and termination style (wire wrap). No circuit modifications or panel rework are required.

Q: What is the difference between these two parts?

A: The primary differences are product status and compliance certifications. The 7201SPDWMES is obsolete, while the 7201SPDWSES is active. The 7201SPDWSES is RoHS compliant and REACH affected, whereas the 7201SPDWMES is RoHS non-compliant and REACH unaffected. Electrical and mechanical performance are identical.

Q: Are there any actuator or termination differences?

A: No. Both parts feature anti-rotation brass actuators with chrome plating, 12.45mm length, and wire wrap termination. The 7201SPDWSES includes epoxy sealed terminals as a feature, while the 7201SPDWMES features a satin chrome actuator. These are design variations that do not affect electrical compatibility.

Q: Which part should be selected for new designs?

A: The 7201SPDWSES should be selected for new designs. It is an active product with current manufacturing support and meets RoHS compliance requirements applicable to most modern applications.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the identical temperature range of -30°C to 85°C with 100,000 cycle electrical life.
