Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS62003DGSG4 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (1.2V fixed)
• Output current capability (600mA minimum)
• Input voltage operating range (2.5V to 5.5V)
• Switching frequency (750kHz)
• Synchronous rectification capability
• Package type (10-TFSOP, 10-MSOP)
• Operating temperature range (-40°C to 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The TPS62003DGS meets all these criteria and is classified as the manufacturer-recommended equivalent. Both parts share the same base product number (TPS62003) and differ only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The TPS62003DGS is the direct functional equivalent to the TPS62003DGSG4. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications across all critical parameters including output voltage, current rating, input voltage range, and switching frequency. The primary distinction is product status: the TPS62003DGSG4 is discontinued, while the TPS62003DGS remains in active production with significantly higher inventory availability (3546 units versus 1110 units).

Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. The packaging difference (Tube versus Tape and Reel) reflects standard distribution methods and does not affect electrical or mechanical compatibility. Selection of the TPS62003DGS ensures access to current inventory and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the TPS62003DGS directly replace the TPS62003DGSG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number, output specifications, input voltage range, switching frequency, and package footprint. The only differences are packaging configuration and product status.

Q: What is the significance of the packaging difference between these parts?

A: The TPS62003DGSG4 is supplied in Tape and Reel format, while the TPS62003DGS is supplied in Tube format. Both are surface-mount 10-TFSOP, 10-MSOP packages with identical 0.118" (3.00mm) width. The packaging format affects distribution and handling but not electrical performance or PCB compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level is 1 (Unlimited) for both devices, indicating no special handling requirements.

Q: Why is the TPS62003DGS recommended over the discontinued TPS62003DGSG4?

A: The TPS62003DGS is actively manufactured and stocked by Texas Instruments with substantially higher inventory availability. This ensures reliable supply chain access and ongoing technical support from the manufacturer.

Q: Are the pin configurations identical between these parts?

A: Yes. Both parts use the 10-TFSOP, 10-MSOP package with identical pin assignments and electrical characteristics, ensuring direct PCB compatibility without layout modifications.
