Engineering Selection Recommendations

For applications currently using the LP2989AIMM-5.0, the LP2989AIMMX-5.0/NOPB is the primary recommended substitute. This part maintains complete parametric equivalence while offering Active product status, ensuring long-term availability and supply chain stability. The LP2989AIMMX-5.0/NOPB is supplied in Tape & Reel packaging, standard for high-volume production environments.

The LP2989AIMM-5.0/NOPB serves as a secondary equivalent option, available in Cut Tape packaging. This part carries Last Time Buy status, indicating limited future availability. Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that the original Obsolete part does not meet.

Selection between LP2989AIMMX-5.0/NOPB and LP2989AIMM-5.0/NOPB should be based on packaging requirements and procurement timelines. For new designs or long-term production, LP2989AIMMX-5.0/NOPB is the preferred choice due to Active status and standard production packaging.

Frequently Asked Questions (FAQ)

Q: Can LP2989AIMM-5.0/NOPB and LP2989AIMMX-5.0/NOPB be used interchangeably with the original LP2989AIMM-5.0?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current capacity, dropout voltage, quiescent current, protection features, and operating temperature range. They are suitable for direct substitution in applications requiring the LP2989AIMM-5.0.

Q: What is the difference between the substitute parts?

A: The primary differences are product status and packaging format. LP2989AIMMX-5.0/NOPB is Active status in Tape & Reel packaging, while LP2989AIMM-5.0/NOPB is Last Time Buy status in Cut Tape packaging. Both maintain identical electrical performance and ROHS3 compliance.

Q: Why is RoHS compliance important for this substitution?

A: The original LP2989AIMM-5.0 is RoHS non-compliant. Both substitute parts achieve ROHS3 compliance, meeting regulatory requirements for electronic components in many markets and applications.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 8-VSSOP package with identical pinout and mechanical dimensions (8-TSSOP, 8-MSOP, 0.118" width, 3.00mm). They are mechanically and electrically interchangeable at the board level.

Q: Which substitute should be selected for new production?

A: LP2989AIMMX-5.0/NOPB is recommended for new production due to Active product status, ensuring continued availability and supply chain reliability. This part is supplied in standard Tape & Reel production packaging.

Q: What is the inventory status of these substitute parts?

A: LP2989AIMMX-5.0/NOPB has 973 Pcs in stock (Active status). LP2989AIMM-5.0/NOPB has 5900 Pcs in stock (Last Time Buy status). Availability should be verified with suppliers for specific procurement requirements.
