Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Mounting type (Through Hole, Right Angle, Vertical)
• Termination style (PC Pin)
• Current rating (minimum 5A AC/DC)
• Voltage ratings (minimum 120V AC, 28V DC)
• Actuator type (Standard Round)
• Operating temperature range (minimum -30°C to 85°C coverage)
• Bushing thread (Unthreaded)

The following parts meet these substitution criteria:

Direct Equivalent (C&K 7101SY9AV2RE): Identical electrical and mechanical specifications with active product status and improved compliance profile.

Similar Substitutes: Grayhill Inc. 34ASP11B2M7QT and Electroswitch A123S1D9AV2Q provide functional equivalence with minor parameter variations within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C&K 7101SY9AV2RE

The C&K 7101SY9AV2RE is the direct equivalent replacement for the obsolete 7101SY9AV2LE. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection of this part eliminates design modification requirements and ensures supply chain continuity within the C&K 7000 series platform.

Secondary Recommendation: Grayhill Inc. 34ASP11B2M7QT

The Grayhill 34ASP11B2M7QT provides functional substitution with ROHS3 compliance. This part accommodates the original application requirements with equivalent voltage and current ratings. The 0.26mm reduction in actuator length and 40,000-cycle electrical life rating represent minor parameter variations suitable for applications not requiring the extended 100,000-cycle specification.

Tertiary Recommendation: Electroswitch A123S1D9AV2Q

The Electroswitch A123S1D9AV2Q offers the highest current rating (6A) and extended operating temperature range (-30°C to 90°C) with RoHS compliance. This part is suitable for applications requiring enhanced electrical performance margins. The 0.26mm actuator length variation and 60,000-cycle electrical life are acceptable for most industrial switching applications.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101SY9AV2RE directly replace the 7101SY9AV2LE without PCB modification?

A: Yes. The 7101SY9AV2RE maintains identical mounting dimensions, pin configuration, and electrical specifications. No PCB layout changes are required.

Q: What is the significance of the 0.26mm actuator length difference in the Grayhill and Electroswitch alternatives?

A: The actuator length variation (10.67mm vs. 10.41mm) affects panel engagement depth. Verify panel thickness and cutout specifications before selection. This difference may require mechanical adjustment in the mounting assembly.

Q: Are the Grayhill and Electroswitch parts suitable for applications requiring 100,000-cycle electrical life?

A: No. The Grayhill part is rated for 40,000 cycles and the Electroswitch for 60,000 cycles. Applications with duty cycles exceeding these specifications require the C&K 7101SY9AV2RE (100,000 cycles).

Q: What compliance advantages does the C&K 7101SY9AV2RE offer over the original part?

A: The 7101SY9AV2RE achieves RoHS compliance and REACH affected status, addressing regulatory requirements for new designs and markets with environmental compliance mandates.

Q: Can these parts be used interchangeably in existing inventory systems?

A: Mechanical and electrical interchangeability is confirmed for all listed substitutes. However, verify actuator length compatibility with existing panel assemblies before bulk substitution.
