C&K 7101SD9AV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SD9AV2LE is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted switch features a standard round actuator with epoxy sealed terminals and operates across -30°C to 85°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-On operation
• Mounting Type: Through Hole, Right Angle, Vertical
• Termination Style: PC Pin
• Current Rating: Minimum 5A (AC/DC)
• Voltage Rating - AC: Minimum 120V
• Voltage Rating - DC: Minimum 28V
• Actuator Type: Standard Round
• Operating Temperature Range: -30°C to 85°C minimum
• Electrical Life: Minimum 40,000 Cycles

Substitute parts are grouped into two categories:

Direct Equivalent: Parts meeting all critical parameters with identical or superior electrical and mechanical specifications.

Similar Substitute: Parts meeting core electrical and mechanical requirements but with minor variations in non-critical parameters such as actuator length, electrical life, or voltage ratings that remain within acceptable operational bounds.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - C&K 7101SD9AV2RE

The 7101SD9AV2RE is the primary direct equivalent for the obsolete 7101SD9AV2LE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration, actuator dimensions, and operating temperature range. The 7101SD9AV2RE maintains the same 100,000-cycle electrical life and is ROHS3 compliant. This part is currently in active production status with 1,059 units in stock. The only distinction is REACH status (Affected vs. Unaffected), which does not affect functional compatibility.

Similar Substitutes - E-Switch 100SP1T1B4M7QE

The E-Switch 100SP1T1B4M7QE meets the core electrical requirements with 5A at 120V AC / 28V DC ratings and identical mounting configuration. The actuator length is reduced to 10.41mm (versus 12.45mm), which may require panel cutout adjustment. Electrical life is rated at 40,000 cycles, lower than the original specification. This part is ROHS3 compliant and REACH unaffected. Use this substitute when panel space constraints favor shorter actuator length.

Similar Substitutes - Grayhill Inc. 34ASP11B2M7QT

The Grayhill 34ASP11B2M7QT provides 5A at 125V AC / 28V DC, exceeding the original voltage specification. Mounting and termination are identical. Actuator length is 10.41mm. Electrical life is 40,000 cycles. This part is ROHS3 compliant and REACH unaffected. The higher AC voltage rating provides additional design margin.

Similar Substitutes - E-Switch 100SP1T1B4M7RE

The E-Switch 100SP1T1B4M7RE is not recommended as a direct substitute. While it shares the same mounting and termination configuration, it is rated for only 0.4VA at 20V AC / 20V DC, which falls below the original 5A at 120V AC specification. This part is suitable only for low-power applications.

Similar Substitutes - Electroswitch A123S1D9AV2Q

The Electroswitch A123S1D9AV2Q exceeds the original specification with 6A at 125V AC / 28V DC ratings. Mounting and termination are identical. Actuator length is 10.41mm. Electrical life is 60,000 cycles. Operating temperature extends to 90°C. This part is RoHS compliant but REACH status is vendor-undefined. Use this substitute when higher current capacity is required.

Frequently Asked Questions (FAQ)

Q: Can I use the E-Switch 100SP1T1B4M7RE as a substitute for the 7101SD9AV2LE?

A: No. The 100SP1T1B4M7RE is rated for 0.4VA at 20V, which does not meet the 5A at 120V AC requirement of the original part. This part is suitable only for low-power signal switching applications.

Q: What is the primary difference between the direct equivalent 7101SD9AV2RE and the original 7101SD9AV2LE?

A: Both parts are electrically and mechanically identical. The only difference is REACH status: the original is REACH Unaffected, while the equivalent is REACH Affected. This does not affect functional performance.

Q: Why do some substitute parts have shorter actuators (10.41mm vs. 12.45mm)?

A: Actuator length affects panel engagement depth and user feel. Shorter actuators may require panel cutout adjustment. Verify mechanical fit in your application before selection.

Q: Which substitute part has the highest electrical life rating?

A: The direct equivalent 7101SD9AV2RE maintains the original 100,000-cycle rating. The Electroswitch A123S1D9AV2Q offers 60,000 cycles, while E-Switch and Grayhill parts offer 40,000 cycles.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes are RoHS3 compliant or RoHS compliant. The Electroswitch A123S1D9AV2Q has vendor-undefined REACH status but maintains RoHS compliance.

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

A: Yes. The A123S1D9AV2Q exceeds the original specification with 6A at 125V AC / 28V DC. It is suitable for applications requiring equal or higher current and voltage ratings. Verify REACH compliance requirements for your supply chain.

Q: What is the inventory status of available substitutes?

A: The C&K 7101SD9AV2RE (direct equivalent) has 1,059 units in stock. E-Switch 100SP1T1B4M7QE has 761 units. Grayhill 34ASP11B2M7QT has 1,002 units. Electroswitch A123S1D9AV2Q has 783 units. All parts are available as new original stock.
