Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with Texas Instruments or National Semiconductor, ensuring continued manufacturing support and availability. Selection among equivalent parts should be based on the following factors:

Packaging Availability: LP2986AIMM-3.3/NOPB and LP2988AIMM-3.3/NOPB are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. LP2986IMM-3.3/NOPB is supplied in Bulk packaging, appropriate for manual assembly or lower-volume applications.

Compliance Documentation: LP2987IMM-3.3/NOPB, LP2986AIMM-3.3/NOPB, and LP2988AIMM-3.3/NOPB carry explicit ROHS3 compliance and Moisture Sensitivity Level 1 certifications. LP2986IMM-3.3/NOPB does not specify these certifications in the provided data.

Inventory Levels: Current stock availability ranges from 1814 to 2654 units across all parts, supporting both immediate procurement and long-term supply chain planning.

Manufacturer Continuity: Texas Instruments manufactures three of the four substitute options, providing consistent technical support and documentation standards.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-3.3/NOPB be used as a direct replacement for LP2987IMM-3.3/NOPB?

A: Yes. Both parts share identical electrical specifications (3.3V output, 200mA current, 0.35V dropout, 65dB PSRR), mechanical packaging (8-VSSOP), and protection features. The primary difference is packaging format: LP2986AIMM-3.3/NOPB is supplied in Tape & Reel, while LP2987IMM-3.3/NOPB is also Tape & Reel. Both are suitable for surface mount assembly.

Q: What is the difference between LP2986IMM-3.3/NOPB and LP2986AIMM-3.3/NOPB?

A: Both parts are electrically and mechanically equivalent. The primary difference is packaging: LP2986IMM-3.3/NOPB is supplied in Bulk packaging by National Semiconductor, while LP2986AIMM-3.3/NOPB is supplied in Tape & Reel by Texas Instruments. Bulk packaging is typically used for manual assembly or lower-volume applications, while Tape & Reel is optimized for automated pick-and-place assembly.

Q: Are all substitute parts RoHS3 compliant?

A: LP2987IMM-3.3/NOPB, LP2986AIMM-3.3/NOPB, and LP2988AIMM-3.3/NOPB are explicitly certified as ROHS3 compliant. LP2986IMM-3.3/NOPB does not specify RoHS status in the provided documentation. Verify compliance requirements with your procurement or quality assurance department before selecting this part.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, all substitute parts use the identical 8-VSSOP package with 0.118" / 3.00mm width and surface mount configuration. PCB footprints, solder pad layouts, and assembly processes remain unchanged. No design modifications are required for mechanical or electrical compatibility.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across the identical temperature range of -40°C to 125°C, supporting industrial and extended-temperature applications without thermal derating.

Q: Which substitute part should I select for automated assembly?

A: LP2986AIMM-3.3/NOPB and LP2988AIMM-3.3/NOPB are supplied in Tape & Reel packaging, which is optimized for automated pick-and-place assembly equipment. LP2986IMM-3.3/NOPB in Bulk packaging is not recommended for high-volume automated processes.
