TL5001IDR Equivalent & Substitute Parts

Part Overview

The TL5001IDR is a Buck, Boost, Flyback Regulator Controller IC manufactured by Texas Instruments, designed for positive output DC-DC conversion applications. This device functions as a transistor driver for step-up, step-down, and step-up/step-down topologies, operating across a wide supply voltage range of 3.6V to 40V with switching frequencies between 20kHz and 500kHz. The part is currently in active production status with 17,159 units available in inventory. Alternative models may be required due to supply constraints, design revisions, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL5001IDR is determined by strict equivalence across the following critical parameters:

• Package Compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Electrical Specifications: Voltage supply range 3.6V ~ 40V, switching frequency 20kHz ~ 500kHz, maximum duty cycle 100%
• Functional Topology: Buck, Boost, and Flyback regulator capability with positive output configuration
• Control Architecture: Transistor driver output with dead time control and frequency control features
• Environmental Ratings: Operating temperature range -40°C ~ 85°C
• Compliance Standards: ROHS3 compliance, MSL Level 1, REACH unaffected status

The TL5001AIDR meets all these criteria as a parametric equivalent within the Texas Instruments TL5001 product family.

Parameter Comparison

Engineering Selection Recommendations

Both the TL5001IDR and TL5001AIDR are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on availability and inventory status. The TL5001IDR currently maintains higher inventory levels at 17,159 units, while the TL5001AIDR has 9,494 units available. Both parts carry ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring environmental regulatory adherence. The identical MSL Level 1 rating indicates both parts have unlimited moisture sensitivity protection, suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can TL5001AIDR be used as a direct replacement for TL5001IDR?

A: Yes. The TL5001AIDR is a parametric equivalent with identical electrical specifications, package configuration, and functional capabilities. Both parts operate within the same voltage supply range (3.6V ~ 40V), switching frequency range (20kHz ~ 500kHz), and temperature range (-40°C ~ 85°C).

Q: Are there any package differences between these parts?

A: No. Both the TL5001IDR and TL5001AIDR use the 8-SOIC package with 0.154" (3.90mm) width. PCB layout and component placement remain identical.

Q: Do these parts have different compliance certifications?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Regulatory and environmental compliance is equivalent.

Q: What determines substitution eligibility for the TL5001IDR?

A: Substitution is determined by matching the following parameters: 8-SOIC package form factor, 3.6V ~ 40V supply voltage range, 20kHz ~ 500kHz switching frequency capability, 100% maximum duty cycle, Buck/Boost/Flyback topology support, transistor driver output type, -40°C ~ 85°C operating temperature range, and ROHS3 compliance status.

Q: Are there any functional differences in control features?

A: No. Both parts provide identical control features including dead time control and frequency control, with no serial interfaces specified for either device.
