Substitute Part Grouping Explanation

Substitution of the BAT54LP-7B-2477 is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse Voltage Rating: 30 V maximum
• Forward Current Capacity: 200 mA average rectified current
• Forward Voltage Drop: 1 V maximum at 100 mA
• Reverse Recovery Time: 5 ns
• Reverse Leakage Current: 2 µA at 25 V
• Junction Capacitance: 10 pF at 1 V, 1 MHz
• Package Type: 0402 (1006 Metric) surface mount
• Technology: Schottky diode
• Automotive Grade: AEC-Q101 qualified
• Temperature Range: -65°C to 125°C junction operating temperature

The BAT54LP-7B-2477 is the tape and reel packaged variant of the base BAT54LP-7B part number. Substitution is valid when all electrical parameters, package dimensions, and qualification standards are identical.

Parameter Comparison

Engineering Selection Recommendations

The BAT54LP-7B is the direct active equivalent for the obsolete BAT54LP-7B-2477. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, package geometry, and automotive qualification status.

Product Status Consideration: The BAT54LP-7B-2477 is classified as obsolete, while the BAT54LP-7B maintains active product status with significantly higher inventory availability (143,343 pieces in stock versus 1,030 pieces for the obsolete variant). This availability differential supports transition to the active part number for new designs and ongoing production requirements.

Compliance and Certification: Both parts maintain AEC-Q101 automotive qualification, RoHS3 compliance, and REACH unaffected status. No compliance gaps exist between the obsolete and active variants.

Packaging Difference: The BAT54LP-7B is supplied in Tape & Reel (TR) packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), whereas the BAT54LP-7B-2477 packaging specification is not detailed in the provided data. For procurement purposes, the active BAT54LP-7B in tape and reel format is the standard supply configuration.

Frequently Asked Questions (FAQ)

Q: Can BAT54LP-7B replace BAT54LP-7B-2477 in existing designs?

A: Yes. The BAT54LP-7B is electrically and mechanically identical to the BAT54LP-7B-2477. All electrical parameters, package dimensions, and automotive qualifications are equivalent. The primary difference is product status (active versus obsolete) and packaging format (tape and reel).

Q: What is the difference between BAT54LP-7B-2477 and BAT54LP-7B?

A: The BAT54LP-7B-2477 is the obsolete variant, while BAT54LP-7B is the active production part. Both share the same electrical specifications (30 V reverse voltage, 200 mA current rating, 1 V forward voltage drop at 100 mA, 5 ns reverse recovery time). The active part is supplied in standard tape and reel packaging.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range (-65°C to 125°C junction temperature) and deliver identical electrical performance across all specified parameters including forward voltage drop, reverse leakage current, reverse recovery time, and junction capacitance.

Q: Is the 0402 (1006 Metric) package the same for both parts?

A: Yes. Both the BAT54LP-7B-2477 and BAT54LP-7B use the 0402 (1006 Metric) surface mount package with identical footprint and land pattern requirements.

Q: Does the BAT54LP-7B meet automotive qualification requirements?

A: Yes. The BAT54LP-7B carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. It maintains the same qualification status as the obsolete BAT54LP-7B-2477.

Q: What is the Moisture Sensitivity Level (MSL) for the BAT54LP-7B?

A: The BAT54LP-7B is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
