TL5001CDG4 Equivalent & Substitute Parts

Part Overview

The TL5001CDG4 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 TL5001CDG4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can TL5001ACD or TL5001CD be used as direct replacements for TL5001CDG4?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including package type, supply voltage range, switching frequency range, control features, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the difference between TL5001ACD and TL5001CD?

A: Both parts are parametrically identical. The primary difference is packaging format (both supplied in Tube) and inventory availability. TL5001CD is designated as the manufacturer-recommended substitute. Selection between these parts should be based on availability and procurement requirements.

Q: Are there any compatibility concerns with the 8-SOIC package?

A: No. All three parts use the identical 8-SOIC (0.154", 3.90mm Width) package. PCB layout, footprint, and assembly processes remain unchanged when substituting between these part numbers.

Q: Do the substitute parts support the same voltage and frequency ranges?

A: Yes. Both TL5001ACD and TL5001CD support identical supply voltage ranges (3.6V ~ 40V) and switching frequency ranges (20kHz ~ 500kHz) as the TL5001CDG4.

Q: Are regulatory certifications maintained with these substitutes?

A: Yes. Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original TL5001CDG4.
