Engineering Selection Recommendations

For new designs and production applications, LP2986IMM-5.0/NOPB is the primary direct substitute, offering identical electrical and mechanical specifications with active product status and ROHS3 compliance. This part provides the highest inventory availability (29,400 units) and represents the most straightforward replacement path.

Alternative LP2986 and LP2987/LP2988 series variants maintain full parametric equivalence and are suitable for applications where the primary substitute is unavailable. All active alternatives carry ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The selection among equivalent variants should be based on inventory availability and supply chain considerations rather than electrical performance, as all parts deliver identical functional characteristics within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-5.0/NOPB directly replace LP2986IMM-5.0?

A: Yes. Both parts deliver identical electrical performance: 5V fixed output, 200mA current capacity, 0.35V dropout voltage, and 120 µA quiescent current. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). The packaging and pinout are identical.

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

A: All three series maintain identical electrical specifications for 5V 200mA output in 8-VSSOP packaging. The series designation reflects internal design revisions by Texas Instruments. From an application standpoint, they are parametrically equivalent and interchangeable.

Q: Are the /NOPB suffix variants different from non-/NOPB versions?

A: The /NOPB suffix indicates lead-free (no lead, no brominated flame retardant) packaging, which is standard for modern RoHS3 compliant parts. The electrical performance is identical; the difference is in material composition and environmental compliance.

Q: Does the X suffix in part numbers like LP2986AIMMX-5.0/NOPB indicate a functional difference?

A: No. The X suffix is a Texas Instruments manufacturing code that does not affect electrical specifications or functional performance. All X and non-X variants of the same base part number are electrically equivalent.

Q: Which substitute part should I select for a new design?

A: LP2986IMM-5.0/NOPB is recommended as the primary choice due to highest inventory availability and direct part number continuity. If unavailable, any active variant from the LP2986, LP2987, or LP2988 series with /NOPB suffix meets all electrical and compliance requirements.

Q: Is the 8-VSSOP package compatible with 8-TSSOP or 8-MSOP footprints?

A: The package designation 8-VSSOP (0.118", 3.00mm Width) is the primary specification. 8-TSSOP and 8-MSOP are alternative naming conventions for the same physical package. All listed parts use this identical package configuration and are footprint-compatible.
