Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54LP-TP is determined by electrical parameter equivalence across the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Capacitance @ Vr, F: 10 pF @ 1 V, 1 MHz
• Operating Temperature - Junction: 125°C

Technology & Compliance (Must Match):

• Technology: Schottky
• RoHS Status: RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Mechanical Consideration:

• Mounting Type: Surface Mount (package form factor may differ while maintaining functional equivalence)

The BAT54L2-TP qualifies as a direct electrical substitute, sharing identical electrical specifications and compliance certifications. The primary distinction is the package configuration: BAT54L2-TP uses DFN1006-2L (0402 Metric) versus BAT54LP-TP's SOD-882 package. Both are surface mount technologies suitable for automated assembly.

Parameter Comparison

Engineering Selection Recommendations

The BAT54L2-TP is the direct electrical equivalent for the obsolete BAT54LP-TP. Both components share identical electrical specifications, reverse recovery characteristics, and compliance certifications. The BAT54L2-TP maintains active product status with higher inventory availability (15,460 pcs versus 1,092 pcs), supporting long-term supply chain continuity.

Selection of BAT54L2-TP requires PCB layout modification to accommodate the DFN1006-2L package footprint in place of the SOD-882 footprint. Both packages are surface mount technologies with equivalent thermal and electrical performance characteristics for the specified application parameters.

RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating are maintained across both components, ensuring regulatory and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can BAT54L2-TP directly replace BAT54LP-TP without circuit modification?

A: Electrical substitution is direct. The components share identical voltage ratings, current ratings, forward voltage characteristics, and reverse recovery times. PCB layout modification is required due to different package geometries (DFN1006-2L versus SOD-882).

Q: What is the primary difference between BAT54LP-TP and BAT54L2-TP?

A: The primary difference is package configuration. BAT54LP-TP uses SOD-882 packaging, while BAT54L2-TP uses DFN1006-2L (0402 Metric) packaging. All electrical parameters, performance characteristics, and compliance certifications are identical.

Q: Are there thermal performance differences between the two packages?

A: Both packages are surface mount configurations with identical operating temperature ratings (125°C junction temperature). Package-specific thermal characteristics depend on PCB layout and thermal management implementation.

Q: Does BAT54L2-TP maintain RoHS3 compliance?

A: Yes. BAT54L2-TP is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of BAT54LP-TP.

Q: Why is BAT54LP-TP classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. BAT54L2-TP represents the active equivalent within the same base product family (BAT54), providing continued access to equivalent Schottky diode functionality.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: 30 V DC reverse voltage rating, 200 mA average rectified current, 1 V forward voltage at 100 mA, 5 ns reverse recovery time, 2 µA reverse leakage current at 25 V, and 10 pF capacitance at 1 V, 1 MHz.
