LP2987IMX-3.0 Equivalent & Substitute Parts

Part Overview

The LP2987IMX-3.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3V output applications with 200mA current capacity in an 8-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part provides essential power management functionality with integrated protection features including over-current, over-temperature, and short-circuit protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LP2987IMX-3.0 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (3V fixed)
• Output current capacity (200mA minimum)
• Maximum input voltage rating (16V)
• Voltage dropout characteristics (0.35V @ 200mA)
• Package type and pinout (8-SOIC)
• Protection feature set (Over Current, Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 125°C)

The LP2987IMX-3.0/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The LP2987IMX-3.0/NOPB is the direct functional equivalent for the obsolete LP2987IMX-3.0. Selection between these parts should be based on the following criteria:

Product Status: The LP2987IMX-3.0/NOPB carries Active status, ensuring continued manufacturer support and availability. The original LP2987IMX-3.0 is classified as Obsolete.

Compliance Certification: The LP2987IMX-3.0/NOPB meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. This distinction is material for applications subject to regulatory compliance mandates.

Packaging Format: The LP2987IMX-3.0/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes. The original part is available in bulk packaging.

Electrical Equivalence: All electrical parameters, including output voltage, current capacity, dropout voltage, quiescent current, PSRR, and protection features, are identical between the two parts.

For new designs or component replacement requiring regulatory compliance, the LP2987IMX-3.0/NOPB is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part meets the electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can LP2987IMX-3.0/NOPB be used as a direct replacement for LP2987IMX-3.0?

A: Yes. Both parts are electrically identical with matching output voltage (3V), output current (200mA), input voltage rating (16V), dropout voltage (0.35V @ 200mA), and protection features. The 8-SOIC package and pinout are identical, enabling direct PCB substitution.

Q: What is the difference between LP2987IMX-3.0 and LP2987IMX-3.0/NOPB?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and packaging format (Bulk vs. Tape & Reel). Electrical performance is identical.

Q: Why is the original LP2987IMX-3.0 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LP2987IMX-3.0/NOPB represents the current active equivalent from Texas Instruments.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and mounting type (Surface Mount). No PCB layout modifications are required.

Q: Does RoHS compliance affect electrical performance?

A: No. ROHS3 compliance relates to material composition and environmental standards, not electrical characteristics. The LP2987IMX-3.0/NOPB maintains identical electrical specifications to the original part.

Q: What packaging format should be selected for production assembly?

A: The LP2987IMX-3.0/NOPB in Tape & Reel format is optimized for automated pick-and-place assembly. Bulk packaging is suitable for manual assembly or low-volume applications.
