BAT54LP-7-79 Equivalent & Substitute Parts

Part Overview

The BAT54LP-7-79 is a Schottky diode manufactured by Diodes Incorporated, rated for 30 V DC reverse voltage and 200 mA average rectified current in a 0402 (1006 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while meeting packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54LP-7-79 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
• Package Configuration: 0402 (1006 Metric) surface mount
• Operating Temperature Range: -65°C to 125°C junction temperature
• Technology Type: Schottky diode

All substitute parts listed maintain these core electrical specifications and physical package dimensions. Differences in reverse leakage current, packaging format (tape & reel versus cut tape), product status (active versus obsolete), and automotive qualification do not preclude functional substitution when electrical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

BAT54LP-7 is the direct parametric equivalent from Diodes Incorporated with active product status. This part maintains identical electrical specifications and package configuration to the BAT54LP-7-79. The primary distinction is product status transition from obsolete to active, with availability in tape & reel packaging format suitable for automated assembly processes.

BAT54LP-7B is an automotive-qualified variant of the BAT54LP-7, carrying AEC-Q101 certification. This part is appropriate for applications requiring automotive-grade component qualification while maintaining all electrical and thermal specifications of the original BAT54LP-7-79.

ACDBQC54-HF is a parametric equivalent manufactured by Comchip Technology with AEC-Q101 automotive qualification. This part exhibits superior reverse leakage performance (500 nA versus 2 µA at 25 V), which may provide operational advantages in low-leakage circuit applications. The supplier device package designation (0402C/SOD-923F) represents an alternative mechanical configuration within the 0402 (1006 Metric) footprint classification.

Selection between these substitutes depends on supply chain requirements, automotive qualification necessity, and reverse leakage performance criteria specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can BAT54LP-7 directly replace BAT54LP-7-79 in existing designs?

A: Yes. The BAT54LP-7 maintains identical electrical specifications across reverse voltage (30 V), forward current (200 mA), forward voltage drop (1 V @ 100 mA), reverse recovery time (5 ns), and operating temperature range (-65°C to 125°C). Both components use the 0402 (1006 Metric) surface mount package. The primary difference is product status; BAT54LP-7 is active production while BAT54LP-7-79 is obsolete.

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

A: Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. BAT54LP-7B includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring certified components. Selection between these variants depends on application requirements for automotive-grade qualification.

Q: Why does ACDBQC54-HF show lower reverse leakage current (500 nA) compared to other substitutes (2 µA)?

A: ACDBQC54-HF is manufactured by Comchip Technology and exhibits superior reverse leakage performance at 25 V. This lower leakage characteristic does not affect substitution eligibility, as all parts meet the specified maximum reverse leakage parameter. Lower leakage may provide operational advantages in circuits sensitive to leakage current effects.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BAT54LP-7, BAT54LP-7B, and ACDBQC54-HF are all ROHS3 compliant with moisture sensitivity level 1 (unlimited), matching the compliance profile of the BAT54LP-7-79.

Q: What packaging formats are available for these substitutes?

A: BAT54LP-7 and BAT54LP-7B are supplied in tape & reel (TR) format for automated assembly. ACDBQC54-HF is also supplied in tape & reel format. All parts use the 0402 (1006 Metric) surface mount package footprint.

Q: Can ACDBQC54-HF be used in automotive applications?

A: Yes. ACDBQC54-HF carries AEC-Q101 automotive qualification, making it suitable for automotive circuit applications. This qualification is equivalent to that of BAT54LP-7B.
