BAS4002LE6327XTMA1 Equivalent & Substitute Parts

Part Overview

The BAS4002LE6327XTMA1 is a Schottky diode manufactured by Infineon Technologies, rated for 40 V DC reverse voltage and 120 mA average rectified current. This surface mount component operates across a junction temperature range of -55°C to 150°C and is classified as a small signal diode with reverse recovery time of 100 ps. The part is currently in active production status and maintains full RoHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where alternative manufacturers or package configurations may be preferred while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS4002LE6327XTMA1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 120 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200 mA (Io)

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: SOD-882
• RoHS Status: ROHS3 Compliant

Compliance Criteria:

• Product Status: Active
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part BAS40L,315 (Nexperia USA Inc.) meets all electrical and mechanical equivalence criteria. Both parts share identical reverse voltage rating, rectified current capacity, forward voltage characteristics, and SOD-882 package specification. Both maintain active production status and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

BAS40L,315 (Nexperia USA Inc.) Substitution Basis:

The BAS40L,315 qualifies as a direct electrical and mechanical substitute for the BAS4002LE6327XTMA1 based on matching specifications across all critical parameters: 40 V reverse voltage rating, 120 mA rectified current capacity, 1 V forward voltage at 40 mA, Schottky technology, and SOD-882 package configuration.

Both parts maintain active production status, full RoHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Both are surface mount components suitable for identical PCB assembly processes.

The Nexperia BAS40L,315 includes AEC-Q100 automotive qualification, which represents an additional compliance credential not specified for the Infineon part. This qualification is applicable in automotive applications but does not affect substitution eligibility in non-automotive contexts.

Reverse leakage current differs between parts: Infineon specifies 1 µA @ 30 V, while Nexperia specifies 10 µA @ 40 V. This difference reflects measurement at different voltage points and does not disqualify substitution where the 40 V rating is the operational reference.

Frequently Asked Questions (FAQ)

Q: Can BAS40L,315 be used as a direct replacement for BAS4002LE6327XTMA1 in existing designs?

A: Yes. Both parts share identical electrical ratings (40 V reverse voltage, 120 mA rectified current, 1 V forward voltage at 40 mA), identical Schottky technology classification, and identical SOD-882 package specification. Both maintain active production status and RoHS3 compliance. No design modification is required for substitution.

Q: Are there package differences between these parts?

A: Both parts use the SOD-882 package / case designation. The Infineon part specifies supplier device package PG-TSLP-2-1, while the Nexperia part specifies DFN1006-2. These represent different supplier nomenclature for the same SOD-882 physical package standard. PCB footprints and assembly processes remain identical.

Q: What is the significance of the AEC-Q100 qualification on the Nexperia part?

A: AEC-Q100 is an automotive industry qualification standard. The Nexperia BAS40L,315 carries this certification, indicating suitability for automotive applications. The Infineon part does not list this qualification. In non-automotive applications, this difference is not relevant to substitution eligibility.

Q: How do reverse leakage current specifications compare?

A: Infineon specifies 1 µA @ 30 V; Nexperia specifies 10 µA @ 40 V. These measurements are taken at different voltage points. At the 40 V rated voltage, the Nexperia specification applies. This difference does not disqualify substitution where 40 V is the operational reference voltage.

Q: Is reverse recovery time (trr) a concern for substitution?

A: The Infineon part specifies 100 ps reverse recovery time. The Nexperia part does not provide this specification in the available data. Both parts are classified as small signal diodes with identical speed classification (≤ 200 mA). Where reverse recovery time is a critical design parameter, the Infineon specification should be verified against application requirements.

Q: Are both parts available in equivalent quantities?

A: Infineon BAS4002LE6327XTMA1 inventory: 15,499 pcs. Nexperia BAS40L,315 inventory: 127,958 pcs. Both are available in tape and reel (TR) packaging for automated assembly. The Nexperia part shows significantly higher inventory availability.
