Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the LP2986IMMX-3.0/NOPB. Selection should be based on the following criteria:

Product Status: The main part is obsolete. All substitute parts are active, ensuring ongoing availability and manufacturing support from Texas Instruments.

Compliance & Certifications: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), ensuring regulatory and environmental compatibility across all options.

Packaging Format: Choose based on procurement and assembly requirements. Tape & Reel (TR) format is standard for automated assembly. Cut Tape (CT) & Digi-Reel® format provides flexibility for lower-volume or mixed-component orders.

Inventory Availability: LP2988IMM-3.0/NOPB offers the highest inventory level (4444 Pcs), followed by LP2986AIMM-3.0/NOPB (2677 Pcs) and LP2988AIMM-3.0/NOPB (2411 Pcs).

Base Product Series: LP2986 and LP2988 series parts are functionally equivalent for this 3V/200mA application. Selection between series does not affect electrical performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-3.0/NOPB directly replace LP2986IMMX-3.0/NOPB?

A: Yes. Both parts share identical electrical specifications (3V output, 200mA current, 0.35V dropout, 65dB PSRR) and package type (8-VSSOP). The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk).

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

A: For the 3V/200mA fixed output configuration specified, LP2986 and LP2988 series parts are electrically equivalent. Both maintain identical output voltage, current capability, dropout voltage, quiescent current, and PSRR specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats contain identical die and electrical characteristics. Format selection is based on procurement volume, assembly automation capability, and supply chain logistics.

Q: What is the MSL rating, and why does it matter?

A: All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing handling costs.

Q: Can I use these parts interchangeably in existing designs?

A: Yes. All substitute parts maintain the same pinout, package footprint (8-VSSOP), electrical specifications, and protection features (Over Current, Over Temperature, Short Circuit). No design modifications are required.
