Substitute Part Grouping Explanation

Substitute parts for the LP2986AIMM-5.0 are determined by strict equivalence across the following critical parameters:

Output voltage: 5V fixed
Output current capacity: 200mA
Input voltage rating: 16V maximum
Voltage dropout: 0.35V @ 200mA
Package type: 8-VSSOP surface mount
Quiescent current: 120 µA
PSRR: 65dB (1kHz)
Protection features: Over Current, Over Temperature, Short Circuit
Operating temperature range: -40°C ~ 125°C

All substitute parts listed maintain identical electrical performance and mechanical compatibility. The primary distinction between parts is product status (active vs. obsolete) and RoHS compliance certification level.

Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to the LP2986AIMM-5.0 and maintain identical electrical and mechanical specifications. Selection among active alternatives should prioritize:

Product Status: All substitute parts carry active product status, ensuring long-term availability and manufacturing support compared to the obsolete LP2986AIMM-5.0.

RoHS Compliance: All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The original LP2986AIMM-5.0 is RoHS non-compliant.

Inventory Availability: LP2986IMM-5.0/NOPB offers the highest inventory level at 29,400 pieces, followed by LP2986AIMMX-5.0/NOPB at 4,400 pieces. All alternatives maintain sufficient stock for production requirements.

Packaging Designation: Parts designated with "/NOPB" suffix indicate lead-free plating and are preferred for new designs and long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-5.0 be directly replaced with LP2986AIMM-5.0/NOPB?

A: Yes. Both parts are electrically and mechanically identical. The /NOPB designation indicates lead-free plating and ROHS3 compliance. Direct substitution is valid for all applications.

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

A: All three series (LP2986, LP2987, LP2988) maintain identical electrical specifications for 5V 200mA output in 8-VSSOP packaging. They are parametrically equivalent and interchangeable based on the provided specifications.

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

A: No. All substitute parts use the 8-VSSOP package with 0.118" width and 3.00mm height. Pinout and mechanical dimensions are identical across all listed alternatives.

Q: Why is the original LP2986AIMM-5.0 marked as obsolete?

A: The original part is classified as obsolete due to product lifecycle management. Active equivalents with superior compliance certifications are available as direct replacements.

Q: Which substitute part should be selected for new designs?

A: Any active substitute part with /NOPB designation is suitable for new designs. LP2986IMM-5.0/NOPB is recommended due to highest inventory availability and active product status.

Q: Are all substitute parts suitable for the full operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 125°C.
