U11SD9AV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U11SD9AV2LE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features a through-hole, right-angle vertical mounting design with PC pin termination and epoxy sealed terminals. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U11SD9AV2LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole, Right Angle, Vertical)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)
• Base product number (U11SD9)

Parts meeting all these criteria are classified as direct functional equivalents. Variations in product status, compliance certifications, or inventory availability do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The U11SD9AV2RE is a direct electrical and mechanical equivalent to the U11SD9AV2LE. Both components share identical circuit topology, current and voltage ratings, mounting configuration, and actuator specifications. The primary distinction is product lifecycle status: the U11SD9AV2LE is obsolete while the U11SD9AV2RE maintains active production status.

For new designs and production applications, the U11SD9AV2RE is the appropriate selection. Both components meet RoHS compliance requirements, with the U11SD9AV2RE classified as RoHS Compliant and the original part as ROHS3 Compliant. REACH status differs between the two parts; this distinction should be evaluated against specific regulatory requirements for the end application.
