C&K 7101SY9AME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SY9AME is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component features through-hole, right-angle mounting with PC pin termination and epoxy sealed terminals. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101SY9AME are grouped based on the following critical parameters that determine functional compatibility:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Actuator type (Standard Round)
• Operating temperature range (-30°C minimum, 85°C maximum)
• Voltage and current ratings within or exceeding the original specifications

Parts are classified as direct equivalents when all critical parameters match the original specification. Parts are classified as similar substitutes when they maintain functional compatibility but may have minor variations in non-critical parameters such as actuator length, electrical life, or voltage rating variance.

Parameter Comparison

Engineering Selection Recommendations

7101SY9ASE (C&K) is the primary direct equivalent. This part maintains identical electrical ratings, mounting configuration, and operating temperature range as the obsolete 7101SY9AME. The 7101SY9ASE carries active product status and is RoHS compliant, providing the most straightforward replacement path with no design modifications required.

34ASP11B4M6QT (Grayhill Inc.) is a functional substitute suitable for applications where the 5A current rating and 125V AC voltage rating are acceptable. The actuator length is 0.26mm shorter (10.41mm vs. 10.67mm), which may require mechanical clearance verification. Electrical life is reduced to 40,000 cycles compared to the original 100,000 cycles. This part is ROHS3 compliant and active in production.

A123S1D9AQ (Electroswitch) is a functional substitute with enhanced current rating of 6A and extended operating temperature range to 90°C. The actuator length is 0.26mm shorter. Electrical life is 60,000 cycles. This part is RoHS compliant and active in production. The higher current rating provides design margin for applications approaching the 5A limit.

Frequently Asked Questions (FAQ)

Q: Can the 7101SY9ASE directly replace the 7101SY9AME without circuit modifications?

A: Yes. The 7101SY9ASE maintains identical electrical specifications, mounting type, termination style, and operating temperature range. No circuit or mechanical modifications are required.

Q: What are the key differences between the direct equivalent and similar substitutes?

A: The direct equivalent (7101SY9ASE) matches all critical parameters. Similar substitutes (34ASP11B4M6QT and A123S1D9AQ) maintain SPDT configuration and mounting type but vary in actuator length (0.26mm shorter), electrical life, and voltage ratings. The Electroswitch part offers higher current rating (6A) and extended temperature range.

Q: Does the 0.26mm difference in actuator length affect mechanical compatibility?

A: Actuator length differences may impact panel cutout clearance and operator feel. Verify mechanical fit within the specific application enclosure before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes carry RoHS or ROHS3 compliance status, meeting environmental regulatory requirements.

Q: Which substitute should be selected for high-cycle applications?

A: The 7101SY9ASE maintains the original 100,000-cycle electrical life rating. For applications requiring extended cycle life, this direct equivalent is the optimal choice. The similar substitutes offer reduced electrical life (40,000 to 60,000 cycles).

Q: Can the Electroswitch A123S1D9AQ be used in applications rated for 5A?

A: Yes. The A123S1D9AQ is rated for 6A, exceeding the 5A requirement. This provides additional design margin and is suitable for 5A applications.
