Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the LP2986IMM-3.0. Selection should be based on the following criteria:

Product Status Consideration: The LP2986IMM-3.0 is Obsolete. All substitute parts carry Active product status, ensuring continued manufacturer support and long-term availability.

RoHS Compliance: The original LP2986IMM-3.0 is RoHS non-compliant. All substitute parts are ROHS3 Compliant, meeting current environmental and regulatory requirements for new designs and production.

Packaging Format: LP2986AIMM-3.0/NOPB, LP2986AIMMX-3.0/NOPB, LP2988AIMM-3.0/NOPB, and LP2988IMM-3.0/NOPB are supplied in Tape & Reel (TR) format. LP2986IMM-3.0/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and assembly line requirements.

Inventory Availability: LP2988IMM-3.0/NOPB offers the highest current inventory at 4,444 pieces. LP2986AIMM-3.0/NOPB provides 2,677 pieces. All parts are available as new original stock.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-3.0/NOPB directly replace LP2986IMM-3.0 in existing designs?

A: Yes. Both parts share identical electrical specifications (3V output, 200mA current, 0.35V dropout, 65dB PSRR) and the same 8-VSSOP package configuration. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

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

A: Both series deliver identical electrical performance for the 3V/200mA configuration specified. The LP2988 series represents a newer product line with the same functional characteristics. All electrical parameters, package type, and protection features are equivalent.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats contain identical die and electrical specifications. Packaging format selection is determined by production volume, assembly equipment compatibility, and supply chain logistics, not performance.

Q: Are the /NOPB suffix parts functionally equivalent to the non-/NOPB version?

A: Yes. The /NOPB designation indicates "No Plumbum" (lead-free) compliance. All electrical and mechanical specifications remain identical. The /NOPB versions are ROHS3 Compliant, making them suitable for current manufacturing standards.

Q: What is the significance of the "X" in LP2986AIMMX-3.0/NOPB?

A: The "X" suffix indicates a specific manufacturing or qualification variant within the LP2986A series. All electrical parameters and package specifications remain identical to LP2986AIMM-3.0/NOPB. Selection between these variants depends on specific supply chain or qualification requirements.

Q: Can these parts be used in new designs, or are they only for replacement applications?

A: All substitute parts carry Active product status and ROHS3 compliance, making them suitable for both new designs and replacement applications. They are fully supported by Texas Instruments for current and future production.
