BD25HA3MEFJ-ME2 Equivalent & Substitute Parts

Part Overview

The BD25HA3MEFJ-ME2 is a linear voltage regulator IC from ROHM Semiconductor designed for positive fixed output applications. This Power Management (PMIC) component delivers 300mA output current at a fixed 2.5V output with a maximum dropout voltage of 1.2V at rated current. The device is housed in an 8-HTSOP-J package and is qualified to AEC-Q100 automotive standards. As an active product with established supply availability, equivalent substitute parts exist within the same product family to support procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the BD25HA3MEFJ-ME2 are identified based on strict parametric equivalence within the ROHM Semiconductor BD25HA3 product family. Substitution is valid when all critical electrical parameters match exactly: output voltage (2.5V fixed), maximum input voltage (8V), output current capability (300mA), dropout voltage specification (1.2V @ 300mA), control features (Enable), protection features (Over Current, Over Temperature, Soft Start), operating temperature range (-40°C ~ 105°C), and package type (8-HTSOP-J). Mechanical compatibility is ensured through identical package and mounting specifications. All substitute parts maintain the same base product number (BD25HA3) and comply with identical regulatory standards (ROHS3, AEC-Q100, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

Both BD25HA3MEFJ-ME2 and BD25HA3MEFJ-LBH2 are active products with full parametric equivalence and identical compliance certifications. The BD25HA3MEFJ-ME2 carries explicit automotive grade designation and AEC-Q100 qualification. Selection between these parts should be based on procurement availability, lead time requirements, and supply chain logistics. Both parts are ROHS3 compliant, REACH unaffected, and maintain unlimited moisture sensitivity classification (MSL 1), ensuring equivalent reliability and handling requirements in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can BD25HA3MEFJ-LBH2 be used as a direct replacement for BD25HA3MEFJ-ME2?

A: Yes. Both parts share identical electrical specifications, output voltage (2.5V), current rating (300mA), dropout voltage (1.2V @ 300mA), protection features, and package type (8-HTSOP-J). All critical parameters for functional equivalence are matched.

Q: Are there differences in automotive qualification between these parts?

A: The BD25HA3MEFJ-ME2 is explicitly designated as automotive grade with AEC-Q100 qualification. The BD25HA3MEFJ-LBH2 specifications provided do not include explicit automotive grade or AEC-Q100 designation. For applications requiring automotive qualification, BD25HA3MEFJ-ME2 is the specified choice.

Q: Do these parts require different PCB layouts or mounting procedures?

A: No. Both parts use identical package specifications (8-SOIC with 0.154" width, 3.90mm exposed pad) and 8-HTSOP-J supplier device package. PCB footprints, mounting procedures, and thermal management approaches are identical.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without desiccant packaging or baking procedures prior to assembly.

Q: Are there supply chain considerations when selecting between these parts?

A: Inventory levels differ between part numbers. BD25HA3MEFJ-ME2 has 1145 pieces in stock while BD25HA3MEFJ-LBH2 has 1086 pieces available. Selection may depend on procurement volume requirements and lead time constraints.
