Engineering Selection Recommendations

The LP3982IMMX-2.82/NOPB is the direct parametric equivalent for the obsolete LP3982IMMX-2.82. Both parts share identical electrical characteristics, output specifications, and package configuration. The substitute part carries Active product status, ensuring ongoing availability and supply chain support.

The LP3982IMMX-2.82/NOPB achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies compliance obligations while maintaining full functional equivalence.

Packaging format differs between the two parts: the original is supplied in bulk configuration, while the substitute is available in Tape & Reel format. This distinction affects procurement and assembly processes but does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can LP3982IMMX-2.82/NOPB be used as a direct replacement for LP3982IMMX-2.82?

A: Yes. Both parts are parametrically equivalent with identical output voltage (2.82V), output current (300mA), input voltage rating (6V maximum), dropout voltage (0.22V @ 200mA), and package configuration (8-VSSOP). Electrical performance and circuit behavior are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (Obsolete versus Active), packaging format (bulk versus Tape & Reel), and RoHS compliance status (non-compliant versus ROHS3 compliant). Electrical specifications and package dimensions are identical.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both parts deliver identical voltage regulation, current capacity, and protection features.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-VSSOP package with 0.118" width and 3.00mm height. PCB footprints and assembly processes are identical.

Q: Which part should be selected for new designs?

A: The LP3982IMMX-2.82/NOPB is recommended for new designs due to Active product status, ensuring long-term availability and supply chain continuity. This part also satisfies RoHS3 compliance requirements for regulated applications.
