Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DB2141300L are identified based on the following critical electrical and mechanical parameters:

Voltage Rating: All substitute parts must maintain a DC reverse voltage rating of 40 V or greater to ensure safe operation within the original circuit design.

Technology: Schottky diode technology is required to preserve the fast recovery characteristics and forward voltage performance of the original component.

Package Type: Surface mount 2-SMD flat lead packages ensure mechanical and thermal compatibility with existing PCB layouts.

Operating Temperature: Maximum junction temperature of 150°C or higher maintains thermal performance equivalence.

Compliance Standards: RoHS compliance status ensures regulatory alignment with the original part.

The substitute parts identified (RB160VAM-40TR and RB160VYM-40FHTR) meet these core substitution criteria. However, current rating differences exist and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

RB160VAM-40TR: This Rohm Semiconductor part maintains active product status with 65,490 units in stock. It meets all core electrical parameters including 40 V reverse voltage rating, fast recovery Schottky technology, and 2-SMD flat lead package compatibility. ROHS3 compliance aligns with regulatory requirements. The 1 A current rating represents a reduction from the original 2 A specification and must be evaluated against circuit load requirements.

RB160VYM-40FHTR: This Rohm Semiconductor part is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. It maintains the same 40 V voltage rating, Schottky technology, and 2-SMD package as the original part. The reverse recovery time of 7.4 ns is superior to the original 12 ns specification. Like the RB160VAM-40TR, the 1 A current rating is lower than the original 2 A rating. ROHS3 compliance and unlimited MSL rating are maintained. This part is suitable for applications requiring automotive qualification.

Both substitute parts exhibit lower reverse leakage current (50 µA versus 150 µA), which represents improved performance. The primary consideration for substitution is the reduced current rating from 2 A to 1 A, which requires circuit-level evaluation to confirm compatibility with application requirements.

Frequently Asked Questions (FAQ)

Q: Can RB160VAM-40TR or RB160VYM-40FHTR be used as direct replacements for DB2141300L?

A: Both parts share identical voltage ratings (40 V), Schottky technology, fast recovery characteristics, and 2-SMD flat lead package configuration. However, the current rating is reduced from 2 A to 1 A. Direct substitution is valid only if circuit current requirements do not exceed 1 A average rectified current.

Q: What is the difference between RB160VAM-40TR and RB160VYM-40FHTR?

A: Both parts are electrically equivalent with identical voltage and current ratings. The RB160VYM-40FHTR carries automotive-grade designation and AEC-Q101 qualification, making it suitable for automotive applications. The RB160VAM-40TR is a standard-grade component. Selection depends on application requirements and qualification standards.

Q: Are the package dimensions compatible between DB2141300L (SMINI2-F4-B-B) and the substitute parts (TUMD2M)?

A: Both packages are classified as 2-SMD flat lead surface mount packages. While supplier device package designations differ, both are mechanically compatible with standard PCB layouts for 2-lead surface mount diodes. Physical verification against PCB footprint specifications is recommended for new designs.

Q: How does the reverse leakage current difference affect circuit performance?

A: The substitute parts exhibit 50 µA reverse leakage at 40 V compared to 150 µA for the original part. This represents improved leakage performance and will result in lower standby current consumption in the circuit.

Q: What is the significance of the reverse recovery time difference?

A: The RB160VYM-40FHTR specifies 7.4 ns reverse recovery time compared to 12 ns for the DB2141300L. Faster recovery time reduces switching losses and improves efficiency in high-frequency applications. The RB160VAM-40TR does not specify reverse recovery time.

Q: Are both substitute parts in active production?

A: Yes. Both RB160VAM-40TR and RB160VYM-40FHTR are listed as active products with substantial inventory availability (65,490 and 6,373 units respectively), ensuring long-term supply continuity.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both substitute parts are ROHS3 compliant, meeting current regulatory requirements. The original DB2141300L is RoHS compliant, and substitution maintains or exceeds compliance standards.
