Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2141IPWPRG4 is determined by strict equivalence across the following critical parameters:

• Identical package and pinout: 14-PowerTSSOP (14-HTSSOP)
• Matching voltage supply range: 4.1V ~ 5.5V
• Equivalent supply current specification: 85µA
• Identical operating temperature range: -40°C ~ 85°C
• Same functional classification: USB adjustable LDO regulator
• Equivalent compliance certifications: ROHS3, REACH Unaffected

The substitute part TPS2141IPWPR meets all these criteria and shares the same base product number (TPS2141), confirming functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TPS2141IPWPR is the direct substitute for the discontinued TPS2141IPWPRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: TPS2141IPWPR maintains active availability with 3300 units in stock, whereas TPS2141IPWPRG4 is discontinued.

For new designs and production applications requiring USB adjustable LDO regulation in the 4.1V to 5.5V supply range, TPS2141IPWPR is the appropriate selection. Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can TPS2141IPWPR directly replace TPS2141IPWPRG4 in existing designs?

A: Yes. Both parts share identical electrical specifications, package dimensions (14-PowerTSSOP), pinout, voltage supply range (4.1V ~ 5.5V), supply current (85µA), and operating temperature range (-40°C ~ 85°C). No circuit modifications are required.

Q: What is the difference between TPS2141IPWPRG4 and TPS2141IPWPR?

A: The parts are electrically and functionally equivalent. The primary difference is product lifecycle status: TPS2141IPWPRG4 is discontinued, while TPS2141IPWPR remains in active production with current inventory availability.
