C&K 7201SYAV2KE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SYAV2KE is a DPDT toggle switch rated for 0.4VA at 20V, designed for panel mount applications with right-angle vertical orientation. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 7201SYAV2KE belongs to the C&K 7000 series and features epoxy sealed terminals with a 100,000-cycle electrical life rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SYAV2KE is determined by strict alignment of the following critical parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount, Right Angle, Vertical
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C

Substitute parts must maintain compatibility across all these parameters to ensure functional equivalence in the original application.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SYAV2PE is the primary direct substitute for the obsolete 7201SYAV2KE. Both parts are manufactured by C&K within the same 7000 series, maintain identical electrical and mechanical specifications, and share the same 100,000-cycle electrical life rating. The 7201SYAV2PE is currently in active production status and is RoHS Compliant, making it suitable for applications requiring modern compliance standards.

The Grayhill Inc. 34ADP11B1M7RT provides an alternative cross-manufacturer substitute that meets all critical electrical and mechanical parameters. However, this part exhibits a reduced electrical life rating of 40,000 cycles compared to the original 100,000-cycle specification. The 34ADP11B1M7RT is ROHS3 Compliant and available in bulk packaging. The actuator length differs by 0.26mm (10.41mm versus 10.67mm), which may require mechanical evaluation in space-constrained panel applications.

For applications requiring the original 100,000-cycle electrical life specification, the C&K 7201SYAV2PE is the recommended selection. For applications where reduced cycle life is acceptable, the Grayhill 34ADP11B1M7RT provides a viable alternative with current product availability.

Frequently Asked Questions (FAQ)

Q: Can the 7201SYAV2PE directly replace the obsolete 7201SYAV2KE without circuit modification?

A: Yes. The 7201SYAV2PE maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (DPDT On-On), and mechanical specifications including panel cutout dimensions, bushing thread, and termination style. No circuit modifications are required.

Q: What is the significance of the actuator length difference between the 7201SYAV2KE and 34ADP11B1M7RT?

A: The 7201SYAV2KE specifies a 10.67mm actuator length, while the 34ADP11B1M7RT provides 10.41mm. This 0.26mm difference may impact applications with tight panel clearance or specific ergonomic requirements. Panel geometry should be evaluated before selection.

Q: Why does the 34ADP11B1M7RT have a lower electrical life rating?

A: The 34ADP11B1M7RT is rated for 40,000 cycles compared to the 100,000-cycle rating of the original part. This specification difference reflects the design characteristics of the Grayhill switch mechanism. Applications requiring extended cycle life should prioritize the C&K 7201SYAV2PE.

Q: Are there compliance differences between the substitute parts?

A: Yes. The original 7201SYAV2KE is RoHS Non-Compliant. The 7201SYAV2PE is RoHS Compliant, and the 34ADP11B1M7RT is ROHS3 Compliant. Applications subject to RoHS requirements should select either the 7201SYAV2PE or 34ADP11B1M7RT.

Q: What packaging options are available for these substitute parts?

A: The 7201SYAV2KE and 7201SYAV2PE are supplied in standard packaging. The 34ADP11B1M7RT is available in bulk packaging, which may affect procurement and handling procedures.

Q: Can the 34ADP11B1M7RT be used in applications originally designed for the 7201SYAV2KE?

A: The 34ADP11B1M7RT meets all critical electrical and mechanical parameters for functional substitution. However, the reduced electrical life rating (40,000 versus 100,000 cycles) and 0.26mm actuator length difference require application-specific evaluation before implementation.
