Substitute Part Grouping Explanation

Substitute parts for the BD50GA5MEFJ-ME2 are qualified based on strict equivalence across the following critical parameters:

Output voltage and current specifications (5V fixed, 500mA)
Input voltage rating (14V maximum)
Dropout voltage performance (1.2V @ 500mA)
Package and case dimensions (8-SOIC with exposed pad)
Mounting technology (Surface Mount)
Operating temperature range (-40°C to 105°C)
Protection features (Over-Current, Over-Temperature, Soft-Start)
Control features (Enable function)
Compliance certifications (ROHS3, REACH Unaffected, AEC-Q100 automotive qualification)
Supplier device package designation (8-HTSOP-J)

Only parts meeting all these criteria are listed as parametric equivalents. Differences in manufacturer suffix codes (such as -ME2 versus -LBH2) reflect packaging or distribution variants from the same manufacturer without affecting electrical or mechanical compatibility.

Engineering Selection Recommendations

Both the BD50GA5MEFJ-ME2 and BD50GA5MEFJ-LBH2 are active production parts from Rohm Semiconductor with identical electrical and mechanical specifications. Selection between these variants is based on availability and supply chain requirements rather than technical performance differences.

The BD50GA5MEFJ-ME2 carries higher inventory availability at 3322 units, making it the primary choice for immediate procurement. The BD50GA5MEFJ-LBH2 is available as a secondary option with 1143 units in stock.

Both parts meet automotive qualification standards (AEC-Q100), comply with ROHS3 regulations, and carry REACH Unaffected status. The identical base product number (BD50GA5), package designation (8-HTSOP-J), and protective feature set ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Are BD50GA5MEFJ-ME2 and BD50GA5MEFJ-LBH2 electrically identical?

A: Yes. Both parts share identical output voltage (5V), output current (500mA), input voltage rating (14V), dropout voltage (1.2V @ 500mA), operating temperature range (-40°C to 105°C), and protection features. The suffix difference reflects packaging or distribution variants only.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the identical 8-SOIC package with exposed pad (0.154", 3.90mm width) and 8-HTSOP-J supplier device package designation. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH Unaffected, and AEC-Q100 qualified for automotive applications. ECCN classification is EAR99 for both variants.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. The BD50GA5MEFJ-ME2 has higher stock levels and is recommended as the primary choice.

Q: Are there any thermal or reliability differences between these variants?

A: No. Both parts operate across the same temperature range (-40°C to 105°C) and include identical protection features: over-current, over-temperature, and soft-start. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both.
