C&K 7101SY9AV2ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SY9AV2ME is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part operates in On-On mode with a through-hole, right-angle vertical mounting design. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring compatible switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SY9AV2ME is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Mounting type must be Through Hole, Right Angle, Vertical
• Termination style must be PC Pin
• Current rating must support minimum 5A (AC/DC)
• Voltage ratings must meet or exceed 120V AC and 28V DC
• Actuator type must be Standard Round
• Bushing must be Unthreaded

Two substitute categories are identified:

Direct Substitute (Same Manufacturer): Parts from C&K that maintain identical electrical and mechanical specifications with active product status.

Similar Substitutes (Alternative Manufacturers): Parts from other manufacturers that meet the core electrical and mechanical requirements but may have minor variations in performance characteristics such as electrical life or actuator length within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

7101SY9AV2SE (C&K Direct Substitute): This is the primary replacement for the obsolete 7101SY9AV2ME. It maintains identical electrical specifications, mechanical configuration, and operating temperature range. The part is currently in active production status with 944 units in stock. RoHS compliance is confirmed. This substitute provides the highest compatibility with existing designs and should be the first choice for direct replacement applications.

34ASP11B2M7QT (Grayhill Inc. Similar Substitute): This part meets all core electrical and mechanical requirements with SPDT configuration, 5A current rating, and 120V+ AC voltage capability. The actuator length is 0.26mm shorter (10.41mm vs. 10.67mm), which may require panel cutout verification. Electrical life is rated at 40,000 cycles compared to the original 100,000 cycles. This substitute is suitable for applications where the reduced cycle life is acceptable. ROHS3 compliance is confirmed.

A123S1D9AV2Q (Electroswitch Similar Substitute): This part exceeds the original specifications with 6A current rating and 125V AC voltage capability. The actuator length matches the Grayhill substitute at 10.41mm. Operating temperature range extends to 90°C. Electrical life is rated at 60,000 cycles. RoHS compliance is confirmed. This substitute is appropriate for applications requiring higher current capacity or extended temperature operation, provided the actuator length difference is accommodated in the mechanical design.

Frequently Asked Questions (FAQ)

Q: Can I use 7101SY9AV2SE as a direct replacement for 7101SY9AV2ME?

A: Yes. The 7101SY9AV2SE is a direct substitute from the same manufacturer with identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), mounting type (Through Hole, Right Angle, Vertical), and operating temperature range (-30°C to 85°C). Both parts feature 100,000 cycle electrical life and PC Pin termination. The primary difference is product status: 7101SY9AV2SE is active production while 7101SY9AV2ME is obsolete.

Q: What are the key differences between the C&K substitute and the alternative manufacturer substitutes?

A: The C&K 7101SY9AV2SE maintains 100% specification alignment with the original part. The Grayhill 34ASP11B2M7QT and Electroswitch A123S1D9AV2Q both have reduced electrical life (40,000 and 60,000 cycles respectively versus 100,000 cycles) and slightly shorter actuators (10.41mm versus 10.67mm). The Electroswitch part offers higher current capacity (6A) and extended temperature range (-30°C to 90°C).

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

A: Actuator length differences may impact panel cutout clearance and toggle engagement. Applications with tight mechanical tolerances or custom panel designs should verify that the 10.41mm actuator length of the Grayhill and Electroswitch substitutes is compatible with existing panel cutouts and mechanical constraints before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 7101SY9AV2SE is RoHS Compliant. The 34ASP11B2M7QT is ROHS3 Compliant. The A123S1D9AV2Q is RoHS Compliant. All substitutes meet applicable RoHS requirements.

Q: Which substitute should I choose for high-cycle applications?

A: For applications requiring maximum electrical life, the 7101SY9AV2SE is the only substitute rated for 100,000 cycles, matching the original part. If the C&K substitute is unavailable, the Electroswitch A123S1D9AV2Q at 60,000 cycles is preferable to the Grayhill 34ASP11B2M7QT at 40,000 cycles for extended-life applications.

Q: Can I use the Electroswitch A123S1D9AV2Q in place of the original part?

A: Yes, with considerations. The A123S1D9AV2Q exceeds the original specifications in current capacity (6A versus 5A) and temperature range (-30°C to 90°C versus -30°C to 85°C). The 0.26mm shorter actuator requires mechanical verification. The 60,000 cycle electrical life is lower than the original 100,000 cycles. This substitute is suitable for applications where higher current capacity is beneficial and reduced cycle life is acceptable.
