Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the LP2986IMMX-3.3/NOPB. Selection should prioritize active product status parts to ensure long-term availability and manufacturing support.

LP2986AIMM-3.3/NOPB, LP2987IMM-3.3/NOPB, LP2987IMMX-3.3/NOPB, LP2988AIMM-3.3/NOPB, LP2988IMM-3.3/NOPB, and LP2988IMMX-3.3/NOPB are all active products with identical specifications. LP2986IMM-3.3/NOPB is also active but sourced from National Semiconductor.

All listed parts comply with ROHS3, carry MSL rating of 1 (Unlimited), and are REACH unaffected. ECCN classification is EAR99 for all variants.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-3.3/NOPB replace LP2986IMMX-3.3/NOPB directly?

A: Yes. Both parts share identical electrical specifications, output voltage, current capacity, dropout voltage, and 8-VSSOP package. The difference is product status (active vs. obsolete) and packaging format (tape & reel vs. bulk).

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

A: All three series maintain identical electrical parameters for the 3.3V 200mA configuration specified. Substitution is valid across all series designations when output voltage and current ratings match.

Q: Are there packaging differences between IMMX and IMM variants?

A: Both IMMX and IMM variants use the same 8-VSSOP package. The X suffix indicates tape & reel packaging format, while non-X variants may use bulk packaging. Electrical performance is identical.

Q: Is the National Semiconductor LP2986IMM-3.3/NOPB compatible?

A: Yes. This part is electrically and mechanically equivalent. National Semiconductor and Texas Instruments share manufacturing lineage for this product line. All parameters match the original specification.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. ECCN classification is EAR99 for all variants.
