LP2966IMM-2525 Equivalent & Substitute Parts

Part Overview

The LP2966IMM-2525 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 2.5V output applications. This dual-output regulator delivers 150mA per channel with integrated protection features including over-current, over-temperature, and short-circuit protection. The device operates across the industrial temperature range of -40°C to 125°C and is housed in an 8-VSSOP surface-mount package.

The LP2966IMM-2525 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications currently utilizing this regulator.

Substitute Part Grouping Explanation

Substitution eligibility for the LP2966IMM-2525 is determined by strict equivalence across the following critical parameters:

Output voltage specification (2.5V fixed), output current capability (150mA minimum), input voltage rating (7V maximum), dropout voltage performance (0.27V @ 150mA), dual-regulator configuration, positive output polarity, and surface-mount packaging in 8-VSSOP form factor.

The LP2966IMM-2525/NOPB qualifies as a direct substitute based on identical electrical specifications, matching package geometry, and equivalent thermal and protection characteristics. The primary distinction between these parts is product status and packaging format: the LP2966IMM-2525/NOPB is active production status and supplied in Tape & Reel format, whereas the original part is obsolete.

Engineering Selection Recommendations

The LP2966IMM-2525/NOPB is the direct substitute for the obsolete LP2966IMM-2525. Both parts share identical electrical performance, thermal characteristics, and mechanical compatibility. The substitute part offers the advantage of active production status, ensuring ongoing availability and supply chain stability.

A significant compliance distinction exists: the LP2966IMM-2525/NOPB meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the LP2966IMM-2525/NOPB is the appropriate selection. For legacy systems or applications without RoHS requirements, both parts remain functionally equivalent.

The packaging format difference (bulk versus Tape & Reel) does not affect electrical or mechanical compatibility. Selection between packaging formats depends on manufacturing process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can the LP2966IMM-2525/NOPB be used as a direct replacement for the LP2966IMM-2525?

A: Yes. Both parts are electrically and mechanically identical. The substitute part features active production status and ROHS3 compliance, making it the preferred choice for new designs and ongoing production.

Q: What is the difference between the bulk and Tape & Reel packaging formats?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel format is optimized for automated pick-and-place assembly processes and high-volume manufacturing. Both formats contain identical components with no electrical or functional differences.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical voltage regulation, current output, and protection characteristics. RoHS3 compliance is a regulatory requirement for certain markets and applications.

Q: Are there any pin-compatibility or footprint concerns when substituting these parts?

A: No. Both parts use the identical 8-VSSOP package with matching pin assignments and PCB footprint dimensions (0.118", 3.00mm width). No layout modifications are required.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient.
