LP2952IMX/NOPB Equivalent & Substitute Parts

Part Overview

The LP2952IMX/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive adjustable (fixed) output applications. This single-output regulator delivers 250mA with a dropout voltage of 0.8V at maximum current and operates across an input voltage range of up to 30V. The device integrates over-current, over-temperature, and reverse-polarity protection, making it suitable for general-purpose power management applications requiring adjustable or fixed voltage regulation.

The LP2952IMX/NOPB maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design continuity when primary stock becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the LP2952IMX/NOPB are identified based on strict parametric equivalence within the LP2952 product family. The substitution criteria are:

• Identical output configuration (Positive)
• Identical output type (Adjustable/Fixed)
• Identical number of regulators (1)
• Identical voltage specifications (Input Max: 30V, Output Min/Fixed: 1.23V/5V, Output Max: 29V)
• Identical dropout voltage (0.8V @ 250mA)
• Identical output current (250mA)
• Identical quiescent current (170 µA)
• Identical protection features (Over Current, Over Temperature, Reverse Polarity)
• Identical operating temperature range (-40°C ~ 125°C)
• Identical package type (16-SOIC)
• Identical compliance certifications (RoHS3, MSL 1)

Parts meeting all these criteria are classified as direct parametric equivalents and may be used interchangeably in circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

Both the LP2952IMX/NOPB and LP2952AIMX/NOPB are Active products from Texas Instruments with identical electrical and mechanical specifications. Both devices maintain full RoHS3 compliance and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Selection between these parts should be based on availability and supply chain requirements. The LP2952AIMX/NOPB currently maintains higher inventory levels (5300 pcs vs. 4156 pcs), making it a viable alternative when primary stock of the LP2952IMX/NOPB is constrained. Both parts are suitable for direct substitution in existing circuit designs without PCB layout modifications or component value adjustments.

Frequently Asked Questions (FAQ)

Q: Can LP2952AIMX/NOPB replace LP2952IMX/NOPB in production designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including output voltage range, current rating, dropout voltage, protection features, and package type. Direct substitution is supported without design changes.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance status and MSL 1 moisture sensitivity rating. REACH and ECCN classifications are identical.

Q: What is the significance of the "A" designation in LP2952AIMX/NOPB?

A: The "A" in the part number indicates a specific manufacturing revision or grade within the LP2952 product family. Both revisions meet identical parametric specifications and are functionally interchangeable.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically equivalent with identical electrical performance and package specifications, they may be used interchangeably within the same design and production run.

Q: What should be verified when substituting between these parts?

A: Verify that the circuit design accommodates the specified input voltage range (up to 30V), output current requirement (250mA maximum), and operating temperature range (-40°C to 125°C). Confirm that the 16-SOIC package footprint matches the PCB layout. No other verification is required for parametrically equivalent parts.
