Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB2460100L is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Package / Case: SOD-128
• Mounting Type: Surface Mount
• Technology: Schottky

Performance Parameters (Allowable Variation):

• Current - Average Rectified (Io): 3 A or greater
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit operating margins
• Reverse Recovery Time (trr): Fast Recovery classification (≤ 500 ns, > 200 mA)
• Current - Reverse Leakage @ Vr: Within acceptable circuit specifications

Substitute parts must satisfy all mandatory matching parameters. Performance parameters may vary within the constraints of the application circuit design. The identified substitutes are grouped based on their ability to fulfill these criteria while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

The RBR3LAM60ATR and RBR3LAM60ATFTR from Rohm Semiconductor are direct electrical equivalents to the DB2460100L. Both parts maintain the 60 V reverse voltage rating, 3 A current rating, and SOD-128 package specification. The forward voltage at 3 A is 660 mV, compared to 650 mV for the original part, representing a 10 mV increase within acceptable circuit operating margins. Reverse leakage current is 100 µA at 60 V, lower than the original 150 µA specification. Both Rohm parts are ROHS3 compliant and carry active product status. The RBR3LAM60ATFTR includes AEC-Q101 automotive qualification and REACH compliance documentation.

Secondary Substitute (Current Rating Reduction):

The CMS14(TE12L,Q,M) from Toshiba Semiconductor and Storage is a 60 V Schottky diode in SOD-128 package with a reduced current rating of 2 A. This part is suitable only for applications where the circuit design permits operation at 2 A or lower. The forward voltage at 2 A is 580 mV, lower than the original specification. Reverse leakage current is 200 µA at 60 V, higher than the original part. This substitute is appropriate for designs with reduced current requirements or where thermal management permits lower current operation.

Frequently Asked Questions (FAQ)

Q: Can the RBR3LAM60ATR directly replace the DB2460100L in existing designs?

A: Yes. The RBR3LAM60ATR maintains identical voltage and current ratings (60 V, 3 A), operates in the same SOD-128 surface mount package, and exhibits compatible electrical characteristics. The 10 mV increase in forward voltage at 3 A is within typical circuit design margins.

Q: What is the difference between RBR3LAM60ATR and RBR3LAM60ATFTR?

A: Both parts are electrically identical 60 V, 3 A Schottky diodes in SOD-128 packages. The RBR3LAM60ATFTR includes AEC-Q101 automotive qualification and REACH compliance status, making it suitable for automotive and regulated applications. The RBR3LAM60ATR is the standard industrial version.

Q: Is the Toshiba CMS14(TE12L,Q,M) a suitable replacement?

A: The CMS14(TE12L,Q,M) is electrically compatible at the voltage level (60 V, SOD-128 package) but has a reduced current rating of 2 A versus the original 3 A. This part is suitable only for applications operating at 2 A or lower. Circuit redesign or thermal analysis is required to confirm compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. The DB2460100L is RoHS Compliant. All identified substitutes (RBR3LAM60ATR, RBR3LAM60ATFTR, and CMS14(TE12L,Q,M)) are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the impact of the lower reverse leakage current in the Rohm parts?

A: The Rohm substitutes (RBR3LAM60ATR and RBR3LAM60ATFTR) exhibit 100 µA reverse leakage at 60 V, compared to 150 µA for the original DB2460100L. Lower reverse leakage current reduces power dissipation and improves circuit efficiency, representing an improvement over the original specification.

Q: Can these parts be used interchangeably in production?

A: The RBR3LAM60ATR and RBR3LAM60ATFTR are interchangeable with the DB2460100L for applications requiring 3 A operation. The CMS14(TE12L,Q,M) requires circuit validation for 2 A operation. All parts are surface mount SOD-128 packages with identical footprints and mounting requirements.

Q: What packaging options are available for the substitute parts?

A: The RBR3LAM60ATR and RBR3LAM60ATFTR are supplied in Cut Tape (CT) and Digi-Reel packaging. The CMS14(TE12L,Q,M) is supplied in Tape & Reel (TR) packaging. Packaging selection depends on production volume and assembly process requirements.
