Substitute Part Grouping Explanation

Substitute parts for the LP2987IM-3.0/NOPB are identified based on strict parametric equivalence across the following critical specifications:

• Output voltage configuration: Positive fixed 3V output
• Output current capability: 200mA minimum
• Input voltage range: Maximum 16V
• Voltage dropout: 0.35V @ 200mA
• Quiescent current: 120 µA
• Package type: 8-SOIC surface mount
• Operating temperature range: -40°C ~ 125°C
• Protection features: Over Current, Over Temperature, Short Circuit
• Control features: Enable function

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The LP2986AIM-3.0/NOPB qualifies as a direct parametric equivalent to the LP2987IM-3.0/NOPB. Both devices are in active production status and meet identical electrical and mechanical specifications across all critical parameters. The substitute part maintains full compatibility with existing PCB layouts and circuit designs due to identical package geometry and pinout configuration.

Both parts comply with ROHS3 standards and carry equivalent regulatory certifications (ECCN: EAR99, HTSUS: 8542.39.0001). Selection between these parts may be based on availability, lead time, or procurement preferences, as no functional or performance differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the LP2986AIM-3.0/NOPB be used as a direct replacement for the LP2987IM-3.0/NOPB?

A: Yes. Both devices share identical electrical specifications including output voltage, current rating, dropout voltage, quiescent current, and protection features. The 8-SOIC package dimensions and pinout are identical, enabling direct PCB substitution without circuit modification.

Q: Are there any differences in package or mounting requirements?
