Equivalent & Substitute Parts for BAT1000Q-7-F

Part Overview

The BAT1000Q-7-F by Diodes Incorporated is an automotive-grade, AEC-Q101 qualified Schottky rectifier diode in a SOT-23-3 (surface mount) package, rated for 40 V reverse voltage and 1A average rectified current. Its high-speed recovery and low forward voltage characteristics make it suitable for surface-mount power and signal rectifier applications. When managing lifecycle, inventory, or multi-sourcing requirements, it is necessary to identify direct equivalents or substitute models, especially in the event of supply interruptions or end-of-life status for key components.

Key Parameters

Substitute Part Grouping Explanation

Strict substitution eligibility for BAT1000Q-7-F is determined by matching these parameters:

• Technology (Schottky)
• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Switching speed and reverse recovery
• Reverse leakage current
• Mounting type and package equivalence (TO-236-3, SC-59, SOT-23-3)
• Automotive grade/AEC-Q101 qualification and RoHS/REACH compliance
• Operating temperature (junction)

The first substitute, BAT1000-7-F, matches all primary parameters and comes from the same manufacturer. The BAS40-00-HE3-08 is a similar SOT-23-3 Schottky diode, also AEC-Q101 qualified, but with reduced maximum average rectified current.

Parameter Comparison

Engineering Selection Recommendations

• BAT1000-7-F is an active status equivalent part with matching key parameters, full RoHS3 and REACH compliance, and AEC-Q101 qualification.
• BAS40-00-HE3-08 is a last time buy product. It has a lower current rating and different forward voltage specification, but matches package, technology, and automotive grade requirements. RoHS3 and REACH unaffected status are present on all compared parts.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when selecting a substitute for BAT1000Q-7-F?
A1: Key parameters include technology (Schottky), maximum DC reverse voltage, average rectified current, forward voltage, package/case, mounting type, automotive qualification (AEC-Q101), operating temperature, and compliance status.

Q2: Are there any differences in mechanical compatibility among the compared parts?
A2: All compared models are available in SOT-23-3 (TO-236-3/SC-59) surface mount packages, supporting drop-in mechanical replacement within standard PCB footprints.

Q3: How does product status affect substitute selection?
A3: Active products such as BAT1000-7-F provide continued availability, while last time buy parts like BAS40-00-HE3-08 may be subject to obsolescence risk and should be considered with current inventory in mind.

Q4: Do all listed substitutes meet automotive and environmental compliance requirements?
A4: Yes, all parts listed are automotive grade (AEC-Q101 qualified) and are both ROHS3 compliant and REACH unaffected based on the provided data.

Q5: Are there differences in current ratings to consider?
A5: BAT1000Q-7-F and BAT1000-7-F support up to 1A average rectified current, whereas BAS40-00-HE3-08 supports 200mA. This is a critical consideration for applications requiring the full 1A capability.
