UCS2113T-2-V/G4 Equivalent & Substitute Parts

Part Overview

The UCS2113T-2-V/G4 is a Power Switch/Driver IC manufactured by Microchip Technology, designed for USB switching applications with 1:1 configuration and 3A output capability. This component operates as a high-side power switch with integrated I2C/SMBus interface control and comprehensive fault protection. The part is currently in active production status with 3477 units available in cut tape packaging. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional characteristics align with the original specification, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the UCS2113T-2-V/G4 are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria include:

• Identical switch type (USB Switch) and output configuration (High Side, 2 outputs)
• Matching input:output ratio (1:1)
• Equivalent electrical specifications: load voltage range (2.9V ~ 5.5V), supply voltage (4.5V ~ 5.5V), maximum output current (3A), and on-resistance (40mOhm typical)
• Identical control interface (I2C, SMBus)
• Matching fault protection features (Current Limiting, Over Temperature, Over Voltage, UVLO)
• Compatible operating temperature range (-40°C ~ 105°C)
• Identical package type (20-VFQFN Exposed Pad) and mounting method (Surface Mount)
• Same manufacturer (Microchip Technology) and base product number (UCS2113)

The UCS2113T-1-V/G4 meets all these criteria and is classified as a parametric equivalent. Differences exist only in packaging format (cut tape versus tape & reel) and moisture sensitivity level specifications, which do not affect functional performance or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the UCS2113T-2-V/G4 and UCS2113T-1-V/G4 are active production parts from Microchip Technology with identical electrical and functional specifications. Selection between these parts is determined by packaging and storage requirements rather than performance characteristics.

The UCS2113T-2-V/G4 with MSL 1 rating is suitable for applications with unlimited shelf life and storage flexibility. The UCS2113T-1-V/G4 with MSL 3 rating requires controlled storage conditions (168-hour maximum exposure to 30°C/60% RH before reflow) and is available in both cut tape and tape & reel formats for automated assembly processes.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and consumer applications. Selection should be based on procurement volume, assembly method (manual versus automated), and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are the UCS2113T-2-V/G4 and UCS2113T-1-V/G4 electrically identical?

A: Yes. Both parts have identical electrical specifications including 3A maximum output current, 40mOhm on-resistance, I2C/SMBus interface, and comprehensive fault protection. They are functionally interchangeable in circuit design.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and moisture sensitivity level. The UCS2113T-2-V/G4 is supplied in cut tape with MSL 1 (unlimited shelf life). The UCS2113T-1-V/G4 is available in both cut tape and tape & reel formats with MSL 3 (168-hour storage limit under controlled conditions).

Q: Can I use the UCS2113T-1-V/G4 in place of the UCS2113T-2-V/G4?

A: Yes, from an electrical and functional standpoint. However, the MSL 3 rating requires adherence to moisture control procedures during storage and handling. If your application does not require tape & reel packaging or automated assembly, the UCS2113T-2-V/G4 may be more practical due to its unlimited shelf life.

Q: What does MSL 1 versus MSL 3 mean for my supply chain?

A: MSL 1 (Unlimited) means the part has no moisture sensitivity restrictions and can be stored indefinitely under normal conditions. MSL 3 (168 Hours) means the part must be used within 168 hours of exposure to 30°C/60% relative humidity, or it must be baked before reflow soldering. This affects inventory management and handling procedures.

Q: Are both parts suitable for high-volume automated assembly?

A: The UCS2113T-1-V/G4 is optimized for automated assembly with tape & reel packaging availability. The UCS2113T-2-V/G4 in cut tape format is suitable for lower-volume or manual assembly processes. Both use identical 20-VFQFN packages compatible with standard surface mount equipment.

Q: Do these parts have the same compliance certifications?

A: Yes. Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and consumer electronics applications.
