Substitute Part Grouping Explanation

Substitution for the BD00HA3MEFJ-LBH2 is determined by strict equivalence across the following critical parameters:

Output configuration (positive), output type (adjustable), maximum input voltage (8V), output voltage range (1.5V to 7V), output current capability (300mA), maximum dropout voltage (1.2V @ 300mA), package type (8-SOIC with exposed pad), mounting method (surface mount), and operating temperature range (-40°C to 105°C).

The substitute part BD00HA3MEFJ-ME2 maintains identical electrical specifications and mechanical packaging. Both parts share the same base product number (BD00HA3) and supplier device package designation (8-HTSOP-J), confirming parametric equivalence. The primary distinction is the packaging variant suffix, which reflects different tape and reel configurations but does not affect functional performance or pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both BD00HA3MEFJ-LBH2 and BD00HA3MEFJ-ME2 are active production parts from Rohm Semiconductor with full ROHS3 compliance. The BD00HA3MEFJ-ME2 carries automotive-grade qualification (AEC-Q100), making it suitable for applications requiring automotive reliability standards. Selection between these parts should be based on application requirements: the standard-grade BD00HA3MEFJ-LBH2 for general industrial and consumer applications, and the automotive-qualified BD00HA3MEFJ-ME2 for automotive or mission-critical environments where AEC-Q100 certification is mandated.

Frequently Asked Questions (FAQ)

Q: Are BD00HA3MEFJ-LBH2 and BD00HA3MEFJ-ME2 pin-compatible?

A: Yes. Both parts use the 8-SOIC package with identical pinout and electrical characteristics. They are direct functional replacements.

Q: What is the difference between the two part numbers?

A: The suffix difference (LBH2 versus ME2) indicates different tape and reel packaging configurations. The electrical specifications and physical package dimensions are identical.

Q: Can I use BD00HA3MEFJ-ME2 in place of BD00HA3MEFJ-LBH2?

A: Yes, provided your application does not require specific tape and reel specifications. The automotive qualification of BD00HA3MEFJ-ME2 makes it suitable for all applications where BD00HA3MEFJ-LBH2 is used.

Q: What are the critical parameters for substitution?

A: Output voltage range (1.5V to 7V), output current (300mA), maximum input voltage (8V), dropout voltage (1.2V @ 300mA), and 8-SOIC package type must remain constant for direct substitution.

Q: Are both parts ROHS3 compliant?

A: Yes. Both BD00HA3MEFJ-LBH2 and BD00HA3MEFJ-ME2 meet ROHS3 compliance requirements.

Q: Which part should I select for automotive applications?

A: BD00HA3MEFJ-ME2 is qualified to AEC-Q100 automotive standards and is the appropriate choice for automotive applications.
