UPS115U/TR7 Equivalent & Substitute Parts

Part Overview

The UPS115U/TR7 is a Schottky diode manufactured by Microchip Technology, rated for 15 V DC reverse voltage and 1 A average rectified current in a Surface Mount Powermite package. This component is classified as Active and is suitable for fast recovery rectification applications requiring low forward voltage drop characteristics. The part is available in Tape & Reel packaging with 686 pieces currently in stock.

Substitute parts are identified to address packaging format availability, compliance requirements, or inventory considerations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the UPS115U/TR7 is determined by equivalence across the following critical parameters:

Voltage - DC Reverse (Vr) (Max): 15 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 220 mV @ 1 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 10 mA @ 15 V
Package / Case: DO-216AA
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C ~ 150°C
Technology: Schottky

The UPS115UE3/TR7 meets all electrical and mechanical requirements for direct substitution. The primary difference between the main part and the substitute is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and compliance certification status.

Engineering Selection Recommendations

The UPS115U/TR7 and UPS115UE3/TR7 are electrically and mechanically equivalent Schottky diodes suitable for direct substitution in applications requiring 15 V, 1 A rectification with fast recovery characteristics.

Selection between these parts should be based on the following factors:

Packaging Format: The UPS115U/TR7 is supplied in Tape & Reel format, while the UPS115UE3/TR7 is available in Cut Tape and Digi-Reel® formats. Choose based on assembly line requirements and quantity needs.

Compliance Requirements: The UPS115UE3/TR7 carries ROHS3 compliance certification, whereas the UPS115U/TR7 is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the UPS115UE3/TR7.

Inventory Availability: The UPS115UE3/TR7 has significantly higher inventory availability (17,370 pieces) compared to the UPS115U/TR7 (686 pieces), which may influence procurement decisions for high-volume production.

Both parts share identical electrical performance, temperature operating range, and moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the UPS115UE3/TR7 be used as a direct replacement for the UPS115U/TR7?

A: Yes. Both parts are electrically and mechanically equivalent, with identical voltage ratings (15 V), current ratings (1 A), forward voltage characteristics (220 mV @ 1 A), and operating temperature range (-55°C ~ 150°C). The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for high-speed automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in cut tape format or on smaller reels, typically used for lower-volume production or mixed-component assembly. Both formats contain the same component in the same package.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. Both parts meet identical electrical and thermal specifications. The UPS115UE3/TR7 is ROHS3 compliant, while the UPS115U/TR7 is RoHS non-compliant. Selection depends on regulatory requirements applicable to the end application.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the same junction temperature range (-55°C ~ 150°C) and share identical reverse leakage characteristics (10 mA @ 15 V). Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.

Q: Which part should be selected for new designs?

A: For new designs, the UPS115UE3/TR7 is the preferred selection due to ROHS3 compliance and higher inventory availability. The UPS115U/TR7 remains suitable for legacy applications or where RoHS non-compliance is not a constraint.
