Substitute Part Grouping Explanation

Substitute parts for the LP2985-10DBVR are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications and package configuration:

• LP2985-10DBVT
• LP2985A-10DBVR
• LP2985A-10DBVT

These parts share the same fixed 10V output voltage, 150mA output current, 16V maximum input voltage, 0.58V dropout voltage, SOT-23-5 package, and identical protection features. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and product status designation.

Functional Substitute offers enhanced performance characteristics:

• TPS7A2401DBVR

This part provides higher output current (200mA vs. 150mA), lower quiescent current (4.5 µA vs. 95 µA), improved dropout voltage (0.25V @ 200mA vs. 0.58V @ 150mA), and higher PSRR (75dB ~ 62dB vs. 45dB). However, the TPS7A2401DBVR features adjustable output voltage (1.24V to 17.75V) rather than fixed 10V output, requiring external resistor network configuration to achieve 10V output. It maintains SOT-23-5 package compatibility and identical operating temperature range.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents): LP2985-10DBVT, LP2985A-10DBVR, and LP2985A-10DBVT are suitable for direct substitution without circuit modification. These parts maintain identical electrical performance and package configuration. Selection among these equivalents should prioritize product status and inventory availability. LP2985A variants and LP2985-10DBVT remain in Last Time Buy status, consistent with the primary part.

For Enhanced Performance Applications: TPS7A2401DBVR is suitable when design specifications permit adjustable output voltage configuration or when improved quiescent current and dropout voltage performance are beneficial. This part requires external resistor network design to establish 10V output and introduces circuit complexity. The TPS7A2401DBVR maintains Active product status, providing superior long-term availability compared to Last Time Buy alternatives. All substitute candidates maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can LP2985-10DBVT be used as a direct replacement for LP2985-10DBVR? A: Yes. LP2985-10DBVT is a parametric equivalent with identical electrical specifications and SOT-23-5 package. The primary difference is packaging format (Cut Tape vs. Tape & Reel configuration). No circuit modifications are required.

Q: What is the difference between LP2985-10DBVR and LP2985A-10DBVR? A: Both parts share identical electrical parameters, output voltage (10V fixed), current rating (150mA), and package type (SOT-23-5). The designation difference reflects manufacturing revision levels. Both are Last Time Buy status parts.

Q: Can TPS7A2401DBVR replace LP2985-10DBVR without design changes? A: TPS7A2401DBVR maintains SOT-23-5 package compatibility and identical operating temperature range. However, it features adjustable output voltage (1.24V to 17.75V) rather than fixed 10V output. Achieving 10V output requires external resistor network configuration. This substitution introduces circuit design changes and is suitable only when design flexibility permits adjustable voltage implementation.

Q: Why is TPS7A2401DBVR listed as a substitute if it requires design modification? A: TPS7A2401DBVR is classified as a functional substitute because it can deliver the required 10V output through external resistor configuration while offering superior performance characteristics (lower quiescent current, improved dropout voltage, higher PSRR). It is the only substitute with Active product status, ensuring long-term availability. Selection depends on design requirements and modification tolerance.

Q: Are all substitute parts ROHS3 compliant? A: Yes. LP2985-10DBVR, LP2985-10DBVT, LP2985A-10DBVR, LP2985A-10DBVT, and TPS7A2401DBVR are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the inventory status of substitute parts? A: LP2985-10DBVR has 35,100 units in stock. LP2985-10DBVT has 20,040 units. LP2985A-10DBVR has 60,300 units (highest availability). LP2985A-10DBVT has 4,095 units. TPS7A2401DBVR has 19,794 units and maintains Active product status.
