LP2960AIM-5.0 Equivalent & Substitute Parts

Part Overview

The LP2960AIM-5.0 is a linear voltage regulator IC from Texas Instruments, delivering a fixed 5V output at 500mA in a 16-SOIC surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The device provides essential power management functionality with integrated protection features including over-current, over-temperature, and reverse polarity protection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2960AIM-5.0 are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Fixed output voltage of 5V
• Minimum output current rating of 500mA
• Maximum input voltage of 30V or greater
• Operating temperature range of -40°C to 125°C
• Surface mount technology
• Integrated protection features (over-current, over-temperature, reverse polarity)

Two substitute parts meet these core requirements with variations in package type and performance characteristics. The LP2960IM-5.0/NOPB maintains identical electrical specifications and package format, while the MIC5239-5.0YMM offers improved performance metrics in a smaller package footprint.

Parameter Comparison

Engineering Selection Recommendations

The LP2960IM-5.0/NOPB is the direct functional equivalent to the LP2960AIM-5.0, offering identical electrical specifications and package format while providing active product status and ROHS3 compliance. This part is suitable for designs requiring pin-for-pin compatibility and existing PCB layouts.

The MIC5239-5.0YMM from Microchip Technology provides an alternative solution with enhanced performance characteristics, including lower dropout voltage (0.35V typical versus 0.8V maximum) and significantly reduced quiescent current (45 µA versus 600 µA). The 8-MSOP package is smaller than the 16-SOIC format, requiring PCB layout modifications. This part includes over-voltage protection in addition to the standard protection features and carries MSL 1 rating for unlimited moisture exposure. Both substitute parts are ROHS3 compliant and carry active product status.

Frequently Asked Questions (FAQ)

Q: Can the LP2960IM-5.0/NOPB be used as a direct replacement for the LP2960AIM-5.0?

A: Yes. The LP2960IM-5.0/NOPB maintains identical electrical specifications, output voltage, current rating, input voltage range, operating temperature range, and 16-SOIC package format. No circuit modifications are required for substitution.

Q: What are the key differences between the LP2960IM-5.0/NOPB and MIC5239-5.0YMM?

A: Both parts deliver 5V at 500mA with identical input voltage and temperature specifications. The MIC5239-5.0YMM offers lower dropout voltage (0.35V typical versus 0.8V maximum) and lower quiescent current (45 µA versus 600 µA), resulting in reduced power dissipation. The MIC5239-5.0YMM uses an 8-MSOP package instead of 16-SOIC, requiring PCB redesign. The MIC5239-5.0YMM includes over-voltage protection and carries MSL 1 rating versus MSL 3 for the LP2960 variants.

Q: Is the MIC5239-5.0YMM package compatible with existing LP2960AIM-5.0 PCB layouts?

A: No. The MIC5239-5.0YMM uses an 8-MSOP package while the LP2960AIM-5.0 uses a 16-SOIC package. PCB layout modifications are required for this substitution.

Q: What compliance certifications apply to these substitute parts?

A: The LP2960IM-5.0/NOPB and MIC5239-5.0YMM are both ROHS3 compliant and REACH unaffected. The original LP2960AIM-5.0 is RoHS non-compliant. Both substitutes carry ECCN EAR99 classification.

Q: How do the moisture sensitivity levels compare?

A: The LP2960AIM-5.0 and LP2960IM-5.0/NOPB carry MSL 3 rating (168 hours maximum exposure). The MIC5239-5.0YMM carries MSL 1 rating (unlimited moisture exposure), providing superior handling flexibility during storage and assembly.
