TPS40193DRCRG4 Equivalent & Substitute Parts

Part Overview

The TPS40193DRCRG4 is a buck regulator positive output step-down DC-DC controller IC manufactured by Texas Instruments in a 10-VSON (3x3) package. This device functions as a transistor driver for single-output, single-phase buck topology applications with a 300kHz switching frequency and 85% maximum duty cycle. The part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the TPS40193DRCRG4 is determined by the following critical parameters:

Identical Parameters (Required for Direct Substitution):

• Package / Case: 10-VFDFN Exposed Pad
• Supplier Device Package: 10-VSON (3x3)
• Output Type: Transistor Driver
• Function: Step-Down
• Output Configuration: Positive
• Topology: Buck
• Number of Outputs: 1
• Output Phases: 1
• Voltage - Supply (Vcc/Vdd): 4.5V ~ 18V
• Duty Cycle (Max): 85%
• Synchronous Rectifier: Yes
• Control Features: Enable, Power Good
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)
• REACH Status: REACH Unaffected

Variable Parameter (Allows Substitution):

• Frequency - Switching: 300kHz (main part) vs. 600kHz (TPS40192 variants)

The TPS40193DRCRG4 has direct equivalents with identical switching frequency (300kHz) and parametric equivalents with higher switching frequency (600kHz). All substitute parts maintain identical electrical and mechanical specifications except for switching frequency.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TPS40193DRCR

The TPS40193DRCR is the manufacturer-recommended direct equivalent. It maintains identical switching frequency (300kHz) and all electrical specifications as the discontinued TPS40193DRCRG4. Product status is Active with 29,100 units in stock. Packaging options include Cut Tape (CT) and Digi-Reel®, providing flexibility for both prototype and production quantities. This part is the optimal choice for direct replacement without circuit redesign.

Secondary Recommendation: TPS40193DRCT

The TPS40193DRCT is an active equivalent with identical switching frequency (300kHz) and electrical specifications. It is supplied in Tape & Reel (TR) packaging, suitable for high-volume production environments. Inventory is 2,400 units. This part is appropriate when Tape & Reel packaging is required for automated assembly processes.

Parametric Equivalent: TPS40192DRCR and TPS40192DRCT

The TPS40192 variants operate at 600kHz switching frequency, double that of the TPS40193DRCRG4. All other electrical and mechanical parameters remain identical. These parts are suitable for applications where higher switching frequency is acceptable or beneficial for reduced component size. The TPS40192DRCR has 34,400 units in stock (highest availability), while TPS40192DRCT has 2,028 units. Both are Active products.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical MSL ratings, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use TPS40192 variants as a direct replacement for TPS40193DRCRG4?

A: The TPS40192 variants are parametric equivalents with identical electrical and mechanical specifications except for switching frequency. TPS40192 operates at 600kHz versus 300kHz for TPS40193. If your circuit design accommodates 600kHz operation, TPS40192 variants are functionally compatible. If your design requires 300kHz operation, use TPS40193DRCR or TPS40193DRCT instead.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) packaging is suitable for small quantities and prototype applications, with parts cut to individual units. Tape & Reel (TR) packaging is designed for high-volume production and automated pick-and-place assembly. Both contain identical die and electrical specifications. Select based on your assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—TPS40193DRCR, TPS40192DRCR, TPS40192DRCT, and TPS40193DRCT—are ROHS3 Compliant with REACH Unaffected status, matching the original TPS40193DRCRG4.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts have MSL 2 (1 Year), indicating they require storage in controlled humidity conditions and have a one-year shelf life from the date of manufacture when stored at specified conditions.

Q: Which substitute part has the highest inventory availability?

A: TPS40192DRCR has the highest inventory with 34,400 units in stock. TPS40193DRCR has 29,100 units. Both are suitable for immediate procurement.
