TL5001IDRG4 Equivalent & Substitute Parts

Part Overview

The TL5001IDRG4 is a Buck, Boost, Flyback Regulator controller IC manufactured by Texas Instruments, designed for positive output step-up, step-down, and step-up/step-down DC-DC conversion applications. This device operates as a transistor driver with integrated dead time control and frequency control features, supporting supply voltages from 3.6V to 40V with switching frequencies between 20kHz and 500kHz.

The TL5001IDRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure project timelines are not disrupted by component unavailability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL5001IDRG4 is determined by strict equivalence across the following critical parameters:

• Output Type: Transistor Driver
• Function: Step-Up, Step-Down, Step-Up/Step-Down
• Topology: Buck, Boost, Flyback
• Number of Outputs: 1
• Output Phases: 1
• Voltage - Supply (Vcc/Vdd): 3.6V ~ 40V
• Frequency - Switching: 20kHz ~ 500kHz
• Duty Cycle (Max): 100%
• Control Features: Dead Time Control, Frequency Control
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant

The TL5001AIDR meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, control architecture, and physical packaging, differing only in packaging format (Tape & Reel vs. standard packaging) and product status.

Parameter Comparison

Engineering Selection Recommendations

The TL5001AIDR is a direct parametric equivalent to the TL5001IDRG4 for all electrical and mechanical specifications. The primary distinction is product status: the TL5001IDRG4 is discontinued, while the TL5001AIDR maintains active status with significantly higher inventory availability (9494 Pcs vs. 684 Pcs).

Both parts are ROHS3 compliant and carry identical MSL ratings, ensuring regulatory and environmental compatibility. The TL5001AIDR is supplied in Tape & Reel format, which is standard for high-volume production environments and does not affect functional performance or PCB integration.

For new designs or component replenishment, the TL5001AIDR is the appropriate selection due to its active product status and superior supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the TL5001AIDR be used as a direct replacement for the TL5001IDRG4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, control features, and 8-SOIC packaging. The TL5001AIDR is functionally interchangeable in all applications designed for the TL5001IDRG4.

Q: What is the difference between the TL5001IDRG4 and TL5001AIDR?

A: The parts are electrically and mechanically identical. The primary differences are packaging format (Tape & Reel for the TL5001AIDR) and product status (active vs. discontinued). The TL5001AIDR also has significantly higher inventory availability.

Q: Are there any PCB layout or design considerations when switching from TL5001IDRG4 to TL5001AIDR?

A: No. Both parts use the same 8-SOIC package footprint (0.154", 3.90mm Width). PCB layouts, pin assignments, and component placement remain unchanged.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TL5001IDRG4 and TL5001AIDR are ROHS3 compliant with MSL rating of 1 (Unlimited). They carry identical REACH and ECCN classifications.

Q: Which part should be selected for new designs?

A: The TL5001AIDR should be selected for new designs due to its active product status and superior supply chain availability. It provides the same performance and reliability as the discontinued TL5001IDRG4.
