TPS40211DRCRG4 Equivalent & Substitute Parts

Part Overview

The TPS40211DRCRG4 is a multi-topology DC-DC controller IC from Texas Instruments designed for boost, flyback, and SEPIC regulator applications with positive output configuration. This device functions as a transistor driver for step-up and step-up/step-down topologies, operating across a wide supply voltage range of 4.5V to 52V with programmable switching frequency between 35kHz and 1MHz.

The TPS40211DRCRG4 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available in active product status with identical electrical and mechanical specifications, differing only in packaging format and moisture sensitivity level ratings.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS40211DRCRG4 is determined by strict equivalence across the following critical parameters:

• Topology: Boost, Flyback, SEPIC
• Output Type: Transistor Driver
• Function: Step-Up, Step-Up/Step-Down
• Output Configuration: Positive
• Supply Voltage Range: 4.5V ~ 52V
• Switching Frequency Range: 35kHz ~ 1MHz
• Control Features: Enable, Frequency Control, Soft Start
• Package Type: 10-VSON (3x3)
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Compliance: ROHS3 Compliant, REACH Unaffected

All substitute parts listed maintain identical electrical specifications and physical package dimensions. Differences exist only in packaging format (tape & reel versus cut tape) and moisture sensitivity level (MSL) ratings, which do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—TPS40210DRCT, TPS40211DRCR, and TPS40211DRCT—are functionally equivalent to the discontinued TPS40211DRCRG4 and maintain active product status with Texas Instruments. Selection between substitutes should be based on the following criteria:

TPS40210DRCT: Available in tape & reel packaging with MSL 2 rating. Suitable for standard production environments with standard moisture control protocols.

TPS40211DRCR: Available in cut tape & Digi-Reel® packaging with MSL 2 rating. Appropriate for applications requiring flexible packaging formats and standard moisture handling.

TPS40211DRCT: Available in cut tape & Digi-Reel® packaging with MSL 1 (unlimited) rating. Recommended for applications with extended storage periods or environments with limited moisture control infrastructure, as the MSL 1 classification eliminates time-based moisture sensitivity constraints.

All substitutes maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected). Selection should prioritize inventory availability and packaging requirements specific to manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can TPS40210DRCT be used as a direct replacement for TPS40211DRCRG4?

A: Yes. TPS40210DRCT is a parametric equivalent with identical electrical specifications, topology support, control features, and operating temperature range. The only differences are packaging format and product status (active versus discontinued).

Q: What is the significance of the MSL rating difference between TPS40211DRCT and the other substitutes?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements, while MSL 2 requires baking if the component has been exposed to moisture for more than one year. TPS40211DRCT with MSL 1 is suitable for long-term storage without time-dependent moisture management protocols.

Q: Are there any functional differences between TPS40211DRCR and TPS40211DRCT?

A: No functional differences exist. Both parts are identical in electrical performance and specifications. The difference is packaging format: TPS40211DRCR uses cut tape & Digi-Reel® format, while TPS40211DRCT also uses cut tape & Digi-Reel® format. Both maintain MSL 2 ratings.

Q: Will substituting the TPS40211DRCRG4 require PCB layout modifications?

A: No. All substitute parts use the identical 10-VSON (3x3) package with 10-VFDFN exposed pad configuration, ensuring pin-for-pin compatibility and identical footprint requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the original TPS40211DRCRG4.

Q: Which substitute should be selected for new designs?

A: For new designs, any of the three active substitutes are appropriate. Selection should be based on packaging preference (tape & reel versus cut tape) and moisture sensitivity requirements. TPS40211DRCT with MSL 1 is recommended for applications with extended storage or limited environmental controls.
