TPS40190DRCTG4 Equivalent & Substitute Parts

Part Overview

The TPS40190DRCTG4 is a Buck Regulator Positive Output Step-Down DC-DC Controller IC manufactured by Texas Instruments in a 10-VSON (3x3) package. This component functions as a transistor driver for step-down voltage conversion applications with a single output phase and positive output configuration.

The TPS40190DRCTG4 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from Texas Instruments with identical electrical and mechanical specifications but different packaging formats and active product status, making them suitable for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts for the TPS40190DRCTG4 are determined by equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution validity:

• Base Product Number: TPS40190 (identical silicon die)
• Output Type, Function, Topology, and Configuration: Transistor Driver, Step-Down, Buck, Positive (identical functional characteristics)
• Voltage Supply Range: 4.5V ~ 15V (identical input specification)
• Switching Frequency: 300kHz (identical operating frequency)
• Duty Cycle Maximum: 85% (identical performance envelope)
• Synchronous Rectifier: Yes (identical feature set)
• Operating Temperature Range: -40°C ~ 85°C (identical thermal specification)
• Package / Case: 10-VFDFN Exposed Pad (identical physical footprint)
• Supplier Device Package: 10-VSON (3x3) (identical pinout and dimensions)
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected (identical regulatory status)

Substitute parts differ only in packaging format (Tape & Reel or Cut Tape & Digi-Reel) and product status (Active vs. Discontinued), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TPS40190DRCT and TPS40190DRCR are direct electrical and mechanical equivalents to the TPS40190DRCTG4. Selection between these substitutes is determined by packaging and supply chain requirements:

TPS40190DRCT is the manufacturer-recommended substitute, supplied in Tape & Reel format with active product status and 1374 units in stock.

TPS40190DRCR is a parametric equivalent supplied in Cut Tape & Digi-Reel format with active product status and significantly higher inventory availability at 53100 units in stock.

All three parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. The choice between TPS40190DRCT and TPS40190DRCR depends on packaging format requirements for assembly processes and inventory lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can TPS40190DRCT or TPS40190DRCR be used as direct replacements for TPS40190DRCTG4?

A: Yes. Both parts are direct substitutes with identical electrical specifications, switching frequency, duty cycle, supply voltage range, output configuration, and thermal operating range. The 10-VSON (3x3) package footprint and pinout are identical across all three part numbers.

Q: What is the difference between TPS40190DRCT and TPS40190DRCR?

A: The primary difference is packaging format. TPS40190DRCT is supplied in Tape & Reel format, while TPS40190DRCR is supplied in Cut Tape & Digi-Reel format. Both maintain identical electrical and mechanical specifications. TPS40190DRCR has significantly higher inventory availability.

Q: Why is TPS40190DRCTG4 discontinued?

A: The TPS40190DRCTG4 is discontinued at DiGi Electronics. However, the base product TPS40190 remains in active production through alternative packaging formats (TPS40190DRCT and TPS40190DRCR), ensuring continued availability of this buck regulator controller.

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

A: No. All three parts maintain identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2, 1 Year) is identical across all variants.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the specific packaging format. TPS40190DRCT (Tape & Reel) and TPS40190DRCR (Cut Tape & Digi-Reel) have identical physical footprints and pinouts, making them interchangeable at the component level. Packaging format selection depends on pick-and-place equipment compatibility and supply chain logistics.
