Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS76515DR is determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Positive fixed 1.5V
• Output current capability: 150mA minimum
• Input voltage rating: 10V maximum
• Package type: 8-SOIC form factor
• Quiescent current: 50 µA
• PSRR performance: 63dB at 1kHz
• Protection and control features: Over-current, over-temperature, reverse polarity protection with enable and power good functions
• Operating temperature range: -40°C to 125°C
• Regulatory compliance: ROHS3 compliant

The TPS76515D qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TPS76515D is the direct equivalent for TPS76515DR applications. Both parts maintain identical electrical and functional specifications across all critical parameters. The TPS76515D carries Active product status, ensuring continued availability and support from Texas Instruments, whereas the TPS76515DR is classified as Obsolete.

Selection between these parts should be based on packaging requirements and supply chain considerations. The TPS76515D is supplied in Tube packaging, while the TPS76515DR was supplied in Tape and Reel format. Both parts meet ROHS3 compliance and REACH requirements, making them suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can TPS76515D directly replace TPS76515DR in existing designs?

A: Yes. The TPS76515D is electrically and functionally identical to TPS76515DR. All electrical parameters, output specifications, protection features, and control functions are equivalent. The 8-SOIC package dimensions are identical, allowing direct PCB substitution.

Q: What is the difference between TPS76515DR and TPS76515D?

A: The primary differences are product status and packaging format. TPS76515DR is Obsolete and supplied in Tape and Reel format. TPS76515D is Active and supplied in Tube packaging. All electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both TPS76515DR and TPS76515D are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across both parts.

Q: What packaging considerations apply to substitution?

A: TPS76515D is supplied in Tube packaging rather than Tape and Reel. This affects handling and automated assembly processes. Verify that your assembly equipment can accommodate Tube packaging, or confirm availability of Tape and Reel formatted TPS76515D if required for automated placement.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both parts use the same 8-SOIC package with 0.154" width (3.90mm). PCB footprints and land patterns are identical, requiring no design modifications for substitution.
