U15P3D9AV2LE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The U15P3D9AV2LE 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 momentary-off-momentary (Mom-Off-Mom) switch function with through-hole, right-angle vertical mounting. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U15P3D9AV2LE is determined by the following critical parameters:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Mounting type: Through Hole, Right Angle, Vertical
• Termination style: PC Pin
• Bushing thread: Unthreaded

Substitute parts must maintain compatibility across these core mechanical and electrical interfaces. Variations in current rating, voltage rating, actuator type, actuator length, and electrical life are permitted when the application requirements allow, provided the substitute part meets or exceeds the minimum specifications for the intended circuit.

Engineering Selection Recommendations

U15P3D9AV2RE (Direct Equivalent)

The U15P3D9AV2RE is the primary substitute for the obsolete U15P3D9AV2LE. Both parts share identical electrical ratings (5A at 120V AC, 28V DC), mechanical configuration, and actuator specifications. The U15P3D9AV2RE maintains active product status and is RoHS compliant. This part provides direct form-fit-function replacement with no design modifications required.

A127S1D9AV2Q (Electroswitch Alternative)

The A127S1D9AV2Q is suitable for applications where the 5A rating of the main part is insufficient. This part provides 6A current capacity at 125V AC with identical DC voltage rating. The actuator length differs (10.41mm versus 13.21mm), requiring mechanical clearance verification. Electrical life is extended to 60,000 cycles. RoHS compliance is confirmed.

A127P31D9AV2B (Electroswitch Alternative)

The A127P31D9AV2B is applicable only for low-power applications requiring 0.5VA maximum. This part operates at 28V AC and DC, limiting its use to circuits not requiring the 120V AC capability of the main part. Actuator length is 11.38mm. This substitute is suitable only when application voltage and current requirements are significantly lower than the original specification.

Frequently Asked Questions (FAQ)

Q: Can U15P3D9AV2RE directly replace U15P3D9AV2LE without design changes?

A: Yes. The U15P3D9AV2RE provides identical electrical ratings, mechanical mounting, and actuator configuration. No circuit or mechanical modifications are required.

Q: What are the key differences between the Electroswitch alternatives and the C&K parts?

A: The Electroswitch A127S1D9AV2Q provides higher current capacity (6A versus 5A) and extended electrical life (60,000 versus 40,000 cycles). The A127P31D9AV2B is limited to 0.5VA operation and 28V AC maximum, making it unsuitable for 120V AC applications. Both Electroswitch parts feature different actuator types and lengths.

Q: Are actuator length differences critical for substitution?

A: Actuator length differences must be evaluated against panel cutout dimensions and mechanical clearance requirements in the specific application. The main part specifies 13.21mm; alternatives range from 10.41mm to 11.38mm. Physical verification is necessary if panel geometry is constrained.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All listed substitute parts are RoHS compliant. The main part is ROHS3 compliant; direct and alternative substitutes meet current RoHS standards.

Q: What is the impact of different electrical life ratings?

A: The main part and U15P3D9AV2RE both specify 40,000 cycles. The Electroswitch alternatives provide 60,000 cycles, indicating extended operational life. Selection should align with application duty cycle requirements.
