TL5001QDR Equivalent & Substitute Parts

Part Overview

The TL5001QDR 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 and switching frequencies between 20kHz and 500kHz.

The TL5001QDR is currently in active product status with 687 units in stock. Equivalent substitute parts are available to address supply chain requirements, inventory optimization, or specific application needs such as automotive qualification or alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL5001QDR is determined by strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Topology: Buck, Boost, Flyback
• Output Type: Transistor Driver
• Function: Step-Up, Step-Down, Step-Up/Step-Down
• Output Configuration: Positive
• 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 ~ 125°C (TJ)

Mechanical Parameters (Must Match):

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed below meet these criteria. Variations in product status, packaging configuration (Tape & Reel vs. bulk), and automotive qualification do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications: The TL5001QDR (687 units in stock) and TL5001AQDRG4Q1 (3507 units in stock) are both active products. The TL5001AQDRG4Q1 offers higher inventory availability and includes AEC-Q100 automotive qualification, making it suitable for automotive applications requiring enhanced reliability screening and traceability.

For Discontinued Product Alternatives: TL5001AQDRG4, TL5001QDRG4, and TL5001AQDG4 are discontinued at DiGi Electronics but remain available in inventory. These parts are electrically and mechanically equivalent to the TL5001QDR and may be selected based on inventory availability and cost considerations. All maintain ROHS3 compliance and identical electrical specifications.

For Automotive Applications: The TL5001AQDRG4Q1 is the only substitute part with automotive-grade qualification (AEC-Q100). This part is recommended for applications requiring automotive-level reliability and qualification documentation.

Packaging Consideration: The TL5001QDR is supplied in Tape & Reel (TR) packaging. TL5001AQDRG4Q1 is also supplied in Tape & Reel (TR) packaging. Other substitute parts do not specify packaging configuration but maintain identical 8-SOIC package geometry.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the TL5001QDR?

A: Yes. All substitute parts share identical electrical specifications including topology (Buck, Boost, Flyback), supply voltage range (3.6V ~ 40V), switching frequency range (20kHz ~ 500kHz), duty cycle (100%), control features (Dead Time Control, Frequency Control), and operating temperature range (-40°C ~ 125°C). They are parametric equivalents.

Q: Can I use TL5001AQDRG4Q1 as a direct replacement for TL5001QDR?

A: Yes. The TL5001AQDRG4Q1 is a direct parametric equivalent with identical electrical and mechanical specifications. The primary differences are product status (both active), automotive qualification (AEC-Q100 for Q1 variant), and higher inventory availability (3507 units vs. 687 units).

Q: What is the difference between TL5001QDR and TL5001AQDRG4?

A: Both parts are parametrically equivalent. The primary difference is product status: TL5001QDR is active, while TL5001AQDRG4 is discontinued at DiGi Electronics. Electrical and mechanical specifications are identical. The "A" designation in TL5001AQDRG4 indicates a variant within the TL5001 base product family.

Q: Are the discontinued parts (TL5001AQDRG4, TL5001QDRG4, TL5001AQDG4) suitable for new designs?

A: Discontinued parts are available in inventory but may face future supply constraints. For new designs, active products (TL5001QDR or TL5001AQDRG4Q1) are recommended to ensure long-term availability and supply chain stability.

Q: Does the 8-SOIC package remain consistent across all substitute parts?

A: Yes. All parts use the 8-SOIC (0.154", 3.90mm Width) package with surface mount mounting type. PCB layout and footprint compatibility is maintained across all substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and have Moisture Sensitivity Level (MSL) 1 (Unlimited). The TL5001AQDRG4Q1 additionally carries AEC-Q100 automotive qualification.

Q: Can I mix TL5001QDR and TL5001AQDRG4Q1 in the same production batch?

A: Yes. Both parts are parametrically equivalent and interchangeable at the circuit level. However, if automotive qualification documentation is required for the entire batch, all units should use TL5001AQDRG4Q1.
