Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP5912-5.0DRVT is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 5V fixed
• Output current rating: 500mA
• Input voltage maximum: 6.5V
• Dropout voltage: 0.18V @ 500mA
• Package type: 6-WDFN Exposed Pad / 6-WSON (2x2)
• Mounting type: Surface Mount
• Control and protection feature set: Enable, Power Good, Soft Start; Over Temperature, Reverse Polarity, Short Circuit
• Operating temperature range: -40°C to 125°C (TJ)

The LP5912-5.0DRVR meets all these criteria as a parametric equivalent. The primary distinction between these part numbers is packaging format: the main part (LP5912-5.0DRVT) is supplied in Tape & Reel format, while the substitute (LP5912-5.0DRVR) is supplied in Cut Tape & Digi-Reel format. Both parts share identical electrical specifications and physical package dimensions.

Parameter Comparison

Engineering Selection Recommendations

The LP5912-5.0DRVR is a direct parametric equivalent to the LP5912-5.0DRVT for all electrical and functional applications. Both parts are manufactured by Texas Instruments and maintain identical electrical performance specifications, thermal characteristics, and protection feature sets.

The primary consideration for part selection is product lifecycle status. The LP5912-5.0DRVT is designated Last Time Buy, indicating limited future availability. The LP5912-5.0DRVR maintains Active product status with significantly higher inventory availability (20,080 pcs vs. 2,434 pcs), making it the preferred choice for new designs and ongoing production requirements.

Both parts satisfy identical compliance requirements: ROHS3 Compliant, REACH Unaffected, MSL Level 1 (Unlimited), and equivalent ECCN and HTSUS classifications. The packaging format difference (Tape & Reel vs. Cut Tape & Digi-Reel) does not affect electrical performance or PCB assembly compatibility, though it may influence procurement logistics and handling procedures based on manufacturing equipment specifications.

Frequently Asked Questions (FAQ)

Q: Are LP5912-5.0DRVT and LP5912-5.0DRVR electrically identical?

A: Yes. Both parts share identical electrical specifications including output voltage (5V), output current (500mA), dropout voltage (0.18V @ 500mA), quiescent current (55 µA), PSRR characteristics, and all control and protection features. They are parametric equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. LP5912-5.0DRVT is supplied in Tape & Reel format, while LP5912-5.0DRVR is supplied in Cut Tape & Digi-Reel format. The physical package dimensions and electrical performance are identical.

Q: Can I use LP5912-5.0DRVR as a direct replacement for LP5912-5.0DRVT in PCB assembly?

A: Yes. Both parts use the same 6-WDFN Exposed Pad package (6-WSON 2x2) with identical pin configuration, footprint, and electrical characteristics. No PCB design changes are required.

Q: Why should I consider switching from LP5912-5.0DRVT to LP5912-5.0DRVR?

A: The LP5912-5.0DRVT carries Last Time Buy status, indicating phase-out. The LP5912-5.0DRVR maintains Active status with substantially higher inventory availability, ensuring long-term supply chain reliability for production and future orders.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical MSL Level 1 (Unlimited) ratings. Compliance certifications and environmental classifications are equivalent.

Q: Does packaging format affect PCB assembly or soldering?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) does not affect the physical component or soldering process. Both formats contain identical parts in the same package. Format selection is determined by manufacturing equipment compatibility and procurement preferences.
