Key Parameters

Substitute Part Grouping Explanation

Substitution of the C&K 7201SD9W5ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (Wire Wrap)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)
• Actuator material (Brass, Chrome Plated)
• Features (Epoxy Sealed Terminals)

The C&K 7201SD9W5SE meets all these parameters and qualifies as a direct substitute within the 7000 series family.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SD9W5SE is the direct substitute for the obsolete 7201SD9W5ME. Both components share identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status and regulatory compliance.

The 7201SD9W5SE is currently in active production status, ensuring availability for new designs and replacement applications. The substitute part carries RoHS Compliant certification, meeting current environmental and material restriction requirements. The main part is classified as RoHS non-compliant and REACH Unaffected, while the substitute is REACH Affected, reflecting updated regulatory frameworks.

For applications requiring RoHS compliance or long-term supply chain stability, the 7201SD9W5SE is the appropriate selection. Functional performance and electrical characteristics remain equivalent across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can the 7201SD9W5SE directly replace the 7201SD9W5ME in existing designs?

A: Yes. The 7201SD9W5SE is electrically and mechanically equivalent to the 7201SD9W5ME. All functional parameters including circuit configuration, current rating, voltage ratings, actuator specifications, and termination style are identical. No circuit modifications are required.

Q: What is the primary reason to transition from 7201SD9W5ME to 7201SD9W5SE?
