Substitute Part Grouping Explanation

Substitute parts for the LP2986AIM-5.0 are classified based on strict electrical and mechanical parameter matching:

Direct Manufacturer Equivalent: LP2986AIM-5.0/NOPB shares identical electrical specifications and package configuration with the main part. The primary difference is packaging format (Tube vs. unspecified) and active product status.

Parametric Equivalents: LP2986IM-5.0/NOPB, LP2987IM-5.0/NOPB, LP2988AIM-5.0/NOPB, and LP2988IM-5.0/NOPB are classified as parametric equivalents because they maintain all critical electrical parameters:

Fixed 5V output voltage
200mA output current capacity
16V maximum input voltage
0.35V maximum dropout voltage at 200mA
120 µA quiescent current
65dB PSRR at 1kHz
8-SOIC package configuration
Identical operating temperature range (-40°C ~ 125°C)
Equivalent protection features (Over Current, Over Temperature, Short Circuit)

All substitute parts are RoHS3 compliant, MSL Level 1, and maintain the same ECCN and HTSUS classifications as the original part.

Engineering Selection Recommendations

Primary Selection: LP2986AIM-5.0/NOPB is the direct equivalent with active product status and highest inventory availability (5200 pcs). This part maintains identical electrical and mechanical specifications while offering superior supply chain continuity.

Secondary Selections: LP2987IM-5.0/NOPB and LP2988IM-5.0/NOPB are active alternatives from Texas Instruments with equivalent parametric performance and RoHS3 compliance. Both maintain full compatibility with the original design specifications.

Alternative Selection: LP2986IM-5.0/NOPB from National Semiconductor provides parametric equivalence with active status, though sourced from a different manufacturer. This option is suitable when primary selections are unavailable.

Compliance Consideration: All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and identical REACH and ECCN classifications, ensuring regulatory and environmental compliance across all options.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIM-5.0/NOPB be used as a direct replacement for LP2986AIM-5.0?

A: Yes. LP2986AIM-5.0/NOPB is the direct equivalent with identical electrical specifications, output voltage, current capacity, dropout voltage, and 8-SOIC package configuration. The primary difference is active product status versus obsolete status.

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

A: All three series maintain identical electrical parameters for 5V, 200mA output applications. The series designation reflects internal design variations, but external electrical performance and package compatibility remain equivalent for this 5V fixed output configuration.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the 8-SOIC (0.154", 3.90mm Width) package configuration, ensuring mechanical and electrical compatibility with existing PCB designs without layout modifications.

Q: Does the /NOPB suffix affect compatibility?

A: No. The /NOPB suffix indicates lead-free plating and RoHS compliance. It does not affect electrical performance or package compatibility. Parts with and without this suffix are functionally equivalent.

Q: Which substitute part offers the best supply chain availability?

A: LP2986AIM-5.0/NOPB provides the highest inventory (5200 pcs), followed by LP2987IM-5.0/NOPB (3800 pcs). Both are active products from Texas Instruments with reliable long-term availability.

Q: Are there any thermal or performance differences between substitute options?

A: No. All substitute parts maintain identical thermal specifications, quiescent current (120 µA), PSRR (65dB at 1kHz), and protection features (Over Current, Over Temperature, Short Circuit). Operating temperature range remains -40°C ~ 125°C across all options.
