Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Electrical Equivalent): LP3892EMR-1.2/NOPB is the direct manufacturer equivalent with Active product status. This part maintains identical electrical performance and package configuration, making it suitable for direct substitution in existing designs without circuit modification.

For Enhanced Performance with Active Status: LP3882EMR-1.2/NOPB offers improved dropout voltage performance (0.32V @ 1.5A) compared to the original specification (0.55V @ 1.5A), resulting in lower power dissipation and improved thermal efficiency. This part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The identical package footprint and electrical interface enable direct PCB compatibility.

Compliance Considerations: The original LP3892EMR-1.2 is RoHS non-compliant. For applications requiring RoHS compliance, LP3882EMR-1.2/NOPB is the appropriate selection. Both substitute parts maintain identical thermal and protection specifications across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can LP3892EMR-1.2/NOPB be used as a direct replacement for LP3892EMR-1.2?

A: Yes. LP3892EMR-1.2/NOPB is a direct manufacturer equivalent with identical electrical specifications, output voltage (1.2V), output current (1.5A), package type (8-PowerSOIC), and protection features. No circuit modifications are required.

Q: What is the difference between LP3892EMR-1.2/NOPB and LP3882EMR-1.2/NOPB?

A: Both parts deliver 1.2V at 1.5A in the same 8-PowerSOIC package. The primary difference is dropout voltage: LP3882EMR-1.2/NOPB has a lower dropout voltage of 0.32V @ 1.5A compared to 0.55V @ 1.5A for LP3892EMR-1.2/NOPB. This results in reduced power dissipation. LP3882EMR-1.2/NOPB also carries ROHS3 compliance.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-PowerSOIC (0.154", 3.90mm Width) package with identical pinout and control features (Enable function). They are mechanically and electrically interchangeable at the PCB level.

Q: Which part should be selected for new designs?

A: LP3882EMR-1.2/NOPB is recommended for new designs. It offers Active product status, improved dropout voltage performance, ROHS3 compliance, and long-term supply availability.

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

A: All three parts operate across -40°C to 125°C, supporting industrial and extended temperature applications.

Q: Are moisture sensitivity levels identical across all parts?

A: The original LP3892EMR-1.2 and LP3882EMR-1.2/NOPB both specify Moisture Sensitivity Level 3 (168 Hours). Moisture sensitivity data for LP3892EMR-1.2/NOPB is not provided in the specification.

Q: Do all parts include the same protection features?
