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

Part Overview

The C&K 7201SYWMI 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 a standard round actuator with wire wrap termination and is designed for applications requiring reliable on-on switching functionality. The 7201SYWMI is classified as obsolete, making identification of equivalent active alternatives essential for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SYWMI 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 (Panel Mount)
  • Actuator specifications (Standard Round, 10.67mm length)
  • Termination style (Wire Wrap)
  • Panel cutout dimensions (Circular - 6.35mm Dia)
  • Bushing thread (1/4-40)
  • Operating temperature range (-30°C ~ 85°C)
  • Electrical life (100,000 Cycles)

The C&K 7201SYWSI meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the 7201SYWMI is obsolete, while the 7201SYWSI is active, making it the recommended alternative for new designs and replacement inventory.

Engineering Selection Recommendations

The C&K 7201SYWSI is the direct equivalent for the obsolete 7201SYWMI. Both parts maintain identical electrical and mechanical specifications, ensuring drop-in compatibility in existing designs. The 7201SYWSI is currently in active production status with 878 units available in stock, providing supply continuity for applications requiring DPDT toggle switches with 5A/120V AC ratings.

Both parts carry EAR99 export classification and comply with RoHS standards. The 7201SYWSI is REACH Affected, while the 7201SYWMI is REACH Unaffected; however, this distinction does not impact functional equivalence. The primary engineering consideration is the transition from the obsolete 7201SYWMI to the active 7201SYWSI for procurement planning and inventory management.

Frequently Asked Questions (FAQ)

Q: Can the 7201SYWSI directly replace the 7201SYWMI in existing applications?

A: Yes. The 7201SYWSI is electrically and mechanically equivalent to the 7201SYWMI. Both parts share identical circuit configuration (DPDT), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), mounting specifications, and actuator dimensions. Panel cutout and bushing thread specifications are identical, enabling direct substitution without design modification.

Q: What is the difference between the 7201SYWMI and 7201SYWSI?

A: The primary difference is product status. The 7201SYWMI is classified as obsolete, while the 7201SYWSI is active. Additionally, the 7201SYWMI features epoxy potted construction, while the 7201SYWSI uses epoxy sealed terminals. Both parts maintain equivalent electrical performance and mechanical compatibility.

Q: Are there any compliance differences between these parts?

A: Both parts comply with RoHS standards and carry EAR99 export classification. The 7201SYWSI is REACH Affected, whereas the 7201SYWMI is REACH Unaffected. This distinction relates to regulatory scope but does not affect functional equivalence or component selection for applications within the specified electrical and temperature parameters.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: DPDT circuit configuration, On-On switch function, 5A current rating, 120V AC and 28V DC voltage ratings, panel mount configuration, standard round actuator at 10.67mm length, wire wrap termination, 6.35mm circular panel cutout, 1/4-40 bushing thread, -30°C to 85°C operating temperature, and 100,000 cycle electrical life.

Q: Is the 7201SYWSI available for immediate procurement?

A: Yes. The 7201SYWSI is in active production status with 878 units currently in stock as new original inventory.
