TL5001ACDRG4 Equivalent & Substitute Parts

Part Overview

The TL5001ACDRG4 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 part operates with a supply voltage range of 3.6V to 40V and supports switching frequencies from 20kHz to 500kHz with 100% maximum duty cycle. The TL5001ACDRG4 is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL5001ACDRG4 is determined by the following critical parameters: package type (8-SOIC), topology (Buck, Boost, Flyback), function (Step-Up, Step-Down, Step-Up/Step-Down), output type (Transistor Driver), supply voltage range (3.6V ~ 40V), switching frequency range (20kHz ~ 500kHz), and maximum duty cycle (100%). All identified substitutes maintain these core electrical and mechanical specifications.

The substitute parts are categorized as follows:

Upgrade Substitute (Active Status): TL5001AIDR offers identical electrical specifications with extended operating temperature range (-40°C ~ 85°C) and active product status, supplied in Tape & Reel packaging.

Parametric Equivalents (Active Status): TL5001ACDR and TL5001CDR maintain identical electrical and thermal specifications to the original part, with active product status and alternative packaging options (Cut Tape & Digi-Reel and Tape & Reel respectively).

Manufacturer Recommended Substitute (Cross-Manufacturer): CS51414EDR8G from onsemi provides functional substitution with step-down topology, though with different output characteristics and extended operating temperature range.

Engineering Selection Recommendations

For direct replacement of the obsolete TL5001ACDRG4, the Texas Instruments TL5001AIDR, TL5001ACDR, and TL5001CDR are the primary candidates. All three maintain identical electrical specifications, package configuration, and regulatory compliance (ROHS3, REACH Unaffected, EAR99). The TL5001AIDR provides the advantage of active product status with extended operating temperature range (-40°C ~ 85°C), making it suitable for applications requiring broader thermal performance. The TL5001ACDR and TL5001CDR offer identical specifications to the original part with active status and alternative packaging formats.

The onsemi CS51414EDR8G represents a cross-manufacturer alternative with step-down topology only, limiting its application to buck converter designs. This part is suitable only for applications that do not require boost or flyback functionality.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical package dimensions, ensuring mechanical and electrical compatibility within their respective functional scope.

Frequently Asked Questions (FAQ)

Q: Can TL5001AIDR directly replace TL5001ACDRG4 in existing designs?

A: Yes. The TL5001AIDR maintains identical electrical specifications, package configuration, and control features. The extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 85°C) provides additional thermal margin. Pin-to-pin compatibility and functional equivalence are confirmed across all specified parameters.

Q: What is the difference between TL5001ACDR and TL5001CDR?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is packaging format: TL5001ACDR is supplied in Cut Tape & Digi-Reel format, while TL5001CDR is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: Is CS51414EDR8G a suitable replacement for all TL5001ACDRG4 applications?

A: No. The CS51414EDR8G supports only step-down (buck) topology, whereas the TL5001ACDRG4 supports buck, boost, and flyback topologies. This substitute is applicable only to designs requiring step-down conversion. Applications requiring boost or flyback functionality must use TL5001 series alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes (TL5001AIDR, TL5001ACDR, TL5001CDR, and CS51414EDR8G) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the original part's regulatory status.

Q: What is the inventory status of these substitutes?

A: TL5001AIDR has 9,494 units in stock, TL5001ACDR has 5,732 units, TL5001CDR has 24,107 units, and CS51414EDR8G has 31,351 units available as new original stock.
