Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2960AIMX-5.0 is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 5V fixed output
• Output current capacity: 500mA minimum
• Input voltage tolerance: 30V maximum
• Voltage dropout characteristics: 0.8V @ 500mA
• Package type: 16-SOIC surface mount
• Protection features: Over-current, over-temperature, and reverse polarity protection
• Control functionality: Enable feature
• Operating temperature range: -40°C ~ 125°C
• Quiescent current: 600 µA
• Supply current: 40 mA maximum

The LP2960AIMX-5.0/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The LP2960AIMX-5.0/NOPB is the direct functional equivalent of the LP2960AIMX-5.0. Selection between these parts should be based on the following criteria:

The LP2960AIMX-5.0/NOPB is recommended for new designs and procurement due to its active product status with Texas Instruments. This part maintains identical electrical and thermal specifications while offering ROHS3 compliance, addressing regulatory requirements for modern manufacturing environments. The tape and reel packaging format is standard for automated assembly processes.

The LP2960AIMX-5.0 remains suitable for legacy system maintenance and repair applications where existing inventory or design documentation specifies this exact part number. However, procurement of this obsolete variant may face extended lead times and limited availability.

Frequently Asked Questions (FAQ)

Q: Can LP2960AIMX-5.0/NOPB be used as a direct replacement for LP2960AIMX-5.0?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including output voltage, current capacity, dropout voltage, protection features, and package configuration. The primary differences are product status and packaging format.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix designates tape and reel packaging format without plating on the leads, as opposed to bulk packaging. This is a standard packaging designation and does not affect electrical performance or pin compatibility.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The LP2960AIMX-5.0/NOPB is ROHS3 compliant, while the LP2960AIMX-5.0 is RoHS non-compliant. For applications subject to RoHS regulations, the LP2960AIMX-5.0/NOPB is the appropriate selection.

Q: Will the LP2960AIMX-5.0/NOPB work in existing PCB designs for the LP2960AIMX-5.0?

A: Yes. Both parts use identical 16-SOIC package dimensions and pin configurations. No PCB layout modifications are required for substitution.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 3 rating with a 168-hour floor life. Standard moisture control procedures during storage and assembly are required.
