U15K9AV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U15K9AV2LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration manufactured by C&K in the 7000 series. This through-hole, right-angle vertical mounted switch is rated for 5A at 120V AC and 28V DC with a momentary-off-momentary (Mom-Off-Mom) switch function. The part is currently obsolete, making identification of equivalent and substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U15K9AV2LE are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Mounting type (Through Hole, Right Angle, Vertical)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

Two substitute categories exist:

Direct Equivalent (U15K9AV2RE): Maintains identical electrical ratings (5A at 120V AC / 28V DC), same series, same actuator specifications, and same termination. Differs only in product status (Active vs. Obsolete) and RoHS compliance variant.

Similar Substitute (34ASP45B2M7RT): Shares the same circuit configuration, mounting type, termination style, and operating temperature range. However, this Grayhill Inc. component operates at reduced electrical ratings (0.4VA at 20V AC/DC) and features a standard round actuator instead of a locking lever, with a longer actuator length (21.32mm vs. 17.88mm).

Parameter Comparison

Engineering Selection Recommendations

U15K9AV2RE (Direct Equivalent): This C&K 7000 series component is the primary substitute for the obsolete U15K9AV2LE. It maintains full electrical and mechanical compatibility with identical current and voltage ratings, actuator specifications, and termination style. The part is currently in active production status with 633 units in stock. Both components meet ROHS3 compliance requirements. Selection of U15K9AV2RE is appropriate for direct replacement in existing designs without circuit modification.

34ASP45B2M7RT (Similar Substitute): This Grayhill Inc. component from the 34A series provides functional equivalence in circuit configuration and mounting characteristics but operates at significantly reduced electrical ratings (0.4VA at 20V versus 5A at 120V AC). The actuator geometry differs, with a standard round type and increased length (21.32mm). This substitute is suitable only for applications where the lower electrical ratings and different actuator type are compatible with system requirements. The part is in active production with 904 units in stock and maintains ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can U15K9AV2RE be used as a direct replacement for U15K9AV2LE?

A: Yes. U15K9AV2RE is a direct equivalent with identical electrical ratings (5A at 120V AC / 28V DC), same circuit configuration (SPDT Mom-Off-Mom), matching mounting type (Through Hole, Right Angle, Vertical), and identical actuator specifications (Locking Lever, 17.88mm length). The primary difference is product status: U15K9AV2RE is active production while U15K9AV2LE is obsolete.

Q: When is 34ASP45B2M7RT appropriate as a substitute?

A: The 34ASP45B2M7RT is suitable only when application requirements accommodate reduced electrical ratings (0.4VA at 20V AC/DC instead of 5A at 120V AC / 28V DC) and a different actuator type (Standard Round instead of Locking Lever). The increased actuator length (21.32mm vs. 17.88mm) must also be compatible with panel cutout and mechanical envelope constraints.

Q: What are the key compatibility parameters for substitution?

A: Critical parameters for substitution are circuit configuration (SPDT), switch function (Mom-Off-Mom), mounting type (Through Hole, Right Angle, Vertical), termination style (PC Pin), operating temperature range (-30°C to 85°C), and electrical life rating (40,000 cycles). Electrical ratings (current and voltage) and actuator specifications must match application requirements.

Q: Are there compliance differences between the main part and substitutes?

A: U15K9AV2LE and 34ASP45B2M7RT are both ROHS3 compliant and REACH unaffected. U15K9AV2RE is RoHS compliant and REACH affected. All three components carry EAR99 ECCN classification and the same HTSUS code (8536.50.9065). Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: What is the inventory status for each substitute?

A: U15K9AV2LE (obsolete) has 775 units in stock. U15K9AV2RE (active) has 633 units in stock. 34ASP45B2M7RT (active) has 904 units in stock. All are listed as new original components.
