TL5002IDG4 Equivalent & Substitute Parts

Part Overview

The TL5002IDG4 is a Boost and Flyback Regulator controller IC manufactured by Texas Instruments, designed for positive output step-up and step-up/step-down DC-DC conversion applications. This device operates as a transistor driver with integrated dead time and frequency control features, supporting input voltage ranges from 3.6V to 40V with switching frequencies between 20kHz and 500kHz.

The TL5002IDG4 is currently discontinued at DiGi Electronics, with 875 units available in new original stock. Due to its discontinued status, identifying functionally equivalent alternatives is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL5002IDG4 is determined by strict equivalence across the following critical parameters:

• Output Type: Transistor Driver
• Function: Step-Up, Step-Up/Step-Down
• Topology: Boost, Flyback
• Number of Outputs: 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 TL5002ID qualifies as a direct substitute, maintaining identical electrical specifications and mechanical compatibility while offering active product status and improved supply chain availability.

Frequently Asked Questions (FAQ)

Q: Is the TL5002ID a direct pin-for-pin replacement for the TL5002IDG4?

A: Yes. Both parts use the 8-SOIC package with identical pinout and electrical characteristics. No circuit modifications are required for substitution.

Q: What is the primary reason to substitute the TL5002IDG4?

A: The TL5002IDG4 is discontinued at DiGi Electronics. The TL5002ID provides identical functionality with active product status and improved supply availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Can the TL5002ID be used in existing designs without PCB modifications?

A: Yes. Identical package dimensions (8-SOIC, 0.154" width, 3.90mm), mounting type (Surface Mount), and electrical specifications ensure direct substitution without design changes.

Q: What are the key electrical parameters that define substitution eligibility?

A: Supply voltage range (3.6V ~ 40V), switching frequency capability (20kHz ~ 500kHz), maximum duty cycle (100%), control features (Dead Time Control, Frequency Control), and operating temperature range (-40°C ~ 85°C) must remain constant across substitute parts.
