BD25IA5MEFJ-ME2 Equivalent & Substitute Parts

Part Overview

The BD25IA5MEFJ-ME2 is a linear voltage regulator IC from Rohm Semiconductor designed for automotive applications. It delivers a fixed 2.5V output at 500mA with integrated protection features including over-current, over-temperature, and soft-start functionality. The device operates across the automotive temperature range of -40°C to 105°C and carries AEC-Q100 qualification for automotive reliability. This part is actively manufactured and widely available in inventory (1078 pcs in stock). Alternative part numbers may be required due to supply chain constraints, regional availability, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The BD25IA5MEFJ-ME2 and its substitute BD25IA5MEFJ-LBH2 share an identical base product number (BD25IA5) and are both manufactured by Rohm Semiconductor. Substitution is valid based on the following critical parameters that remain constant across both parts:

Fixed output voltage of 2.5V
Output current rating of 500mA
Maximum input voltage of 5.5V
Voltage dropout specification of 0.9V @ 500mA
Quiescent current of 0.25 mA
Operating temperature range of -40°C to 105°C
Identical package configuration: 8-SOIC with exposed pad
Identical protection features: Over Current, Over Temperature, Soft Start
Enable control feature present on both variants
Both parts are ROHS3 compliant with MSL 1 rating

The suffix variation (-ME2 versus -LBH2) represents different packaging or distribution channel designations from Rohm Semiconductor but does not alter the electrical or mechanical specifications of the regulator IC itself.

Engineering Selection Recommendations

Both BD25IA5MEFJ-ME2 and BD25IA5MEFJ-LBH2 are active products from Rohm Semiconductor with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and procurement channel requirements. The BD25IA5MEFJ-ME2 currently has higher stock availability (1078 pcs) compared to BD25IA5MEFJ-LBH2 (926 pcs). Both parts maintain identical electrical performance, thermal characteristics, and protection functionality across the full automotive operating temperature range. PCB layout and design considerations remain unchanged when substituting between these part numbers, as mechanical and electrical interfaces are identical.

Frequently Asked Questions (FAQ)

Q: Can BD25IA5MEFJ-LBH2 be used as a direct replacement for BD25IA5MEFJ-ME2?

A: Yes. Both parts share identical electrical specifications, output voltage, current rating, dropout voltage, operating temperature range, and package configuration. The suffix variation represents different distribution channels or packaging designations from Rohm Semiconductor but does not affect functional performance or PCB compatibility.

Q: Are there any differences in the 8-SOIC package between these two part numbers?

A: No. Both parts use the identical 8-SOIC package with 0.154" width (3.90mm) and exposed pad configuration. PCB footprints, solder pad layouts, and thermal characteristics are identical.

Q: Do both parts support the same control and protection features?

A: Yes. Both BD25IA5MEFJ-ME2 and BD25IA5MEFJ-LBH2 include Enable control functionality and identical protection features: Over Current, Over Temperature, and Soft Start protection.

Q: What is the significance of the different part number suffixes (-ME2 vs -LBH2)?

A: The suffix variation indicates different packaging or distribution designations assigned by Rohm Semiconductor. These designations do not reflect differences in the IC die, electrical performance, or mechanical specifications.

Q: Are both parts qualified for automotive applications?

A: The BD25IA5MEFJ-ME2 carries explicit AEC-Q100 automotive qualification. Both parts operate across the automotive temperature range (-40°C to 105°C) and maintain active product status with full compliance certifications.

Q: What is the moisture sensitivity level for these parts?
