LP2986AIMMX-5.0 Equivalent & Substitute Parts

Part Overview

The LP2986AIMMX-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications with 200mA current capacity in an 8-VSSOP surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering current product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: output voltage (5V fixed), output current (200mA), input voltage rating (16V maximum), voltage dropout specification (0.35V @ 200mA), quiescent current (120 µA), PSRR (65dB at 1kHz), package type (8-VSSOP), operating temperature range (-40°C to 125°C), and protection features (Over Current, Over Temperature, Short Circuit). All identified substitute parts meet these criteria without exception. Differences in product status (obsolete versus active) and RoHS compliance certifications do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

All substitute parts listed maintain complete electrical and mechanical equivalence to the LP2986AIMMX-5.0. The primary distinction is product status: the original part is obsolete while all substitutes are active. All substitute parts carry ROHS3 compliance certification, whereas the original part is non-compliant. For new designs and production continuity, LP2986IMM-5.0/NOPB is the preferred selection due to highest inventory availability (29,400 units). For direct form-fit-function replacement with minimal design impact, LP2986AIMMX-5.0/NOPB provides the closest variant designation while offering active status and improved compliance. Parts within the LP2987 and LP2988 series provide equivalent functionality with identical electrical specifications and package compatibility.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts pin-compatible with the LP2986AIMMX-5.0?

A: Yes. All substitute parts use the 8-VSSOP package with identical pinout, mechanical dimensions (0.118" width, 3.00mm), and surface mount footprint specifications.

Q: What is the difference between LP2986, LP2987, and LP2988 series parts?

A: Within the 5V fixed output configuration specified, these series variants maintain identical electrical performance across output voltage, current capacity, dropout voltage, quiescent current, and PSRR specifications. All are mechanically and electrically interchangeable for this application.

Q: Why is the original LP2986AIMMX-5.0 marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. Active equivalents with identical specifications are available as direct replacements.

Q: Does the /NOPB suffix affect compatibility?

A: The /NOPB suffix indicates lead-free plating and does not affect electrical or mechanical compatibility. It reflects manufacturing process compliance.

Q: Which substitute part should be selected for maximum inventory availability?

A: LP2986IMM-5.0/NOPB offers the highest inventory level at 29,400 units while maintaining complete equivalence.

Q: Are there compliance differences between substitute options?

A: All substitute parts are ROHS3 compliant. The original LP2986AIMMX-5.0 is RoHS non-compliant. For applications requiring RoHS compliance, any listed substitute is suitable.
