Engineering Selection Recommendations

All substitute parts listed maintain electrical equivalence to the DB107S across the critical parameters of peak reverse voltage, average rectified current, forward voltage, and reverse leakage current. Selection among these alternatives should be based on:

Compliance and Certification: ROHS3 compliance is confirmed for all parts except DF10S1. DBLS107GH carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components.

Reverse Leakage Performance: DBLS107G and DBLS107GH exhibit lower reverse leakage (2 µA @ 1000 V) compared to the DB107S specification (5 µA @ 1000 V), providing enhanced performance margin in leakage-sensitive applications.

Inventory Availability: DF10S-E3/77 (26,100 units) and ABS10A-13 (20,206 units) offer the highest stock levels among substitutes. B1010S_R2_00001 (3,308 units) and DBLS107G (2,033 units) have limited availability.

Packaging Format: All parts are qualified for 4-SMD, Gull Wing surface mount assembly. Packaging format variations (Cut Tape, Tape & Reel, Bulk) do not affect functional performance and should be selected based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute DB107S with any of the listed parts without circuit modification?

A: Yes. All listed parts meet the core electrical specifications: 1 kV peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and reverse leakage of 5 µA or lower at 1000 V. The 4-SMD, Gull Wing package is identical across all parts, enabling direct PCB footprint compatibility.

Q: What is the difference between DB107S from SMC Diode Solutions and DB107S from MDD?

A: Both parts share the same part number and electrical ratings. The MDD version specifies 10 µA reverse leakage at 1000 V, compared to 5 µA for the SMC version. This represents a relaxed leakage specification and may be acceptable depending on circuit requirements. Verify with your design specifications before substitution.

Q: Are DBLS107G and DBLS107GH interchangeable?

A: DBLS107G and DBLS107GH are electrically equivalent with identical 1 kV, 1 A ratings and 2 µA reverse leakage. DBLS107GH carries AEC-Q101 automotive qualification. Select DBLS107GH for automotive applications; either part is suitable for general industrial use.

Q: Does the packaging format (Cut Tape vs. Tape & Reel vs. Bulk) affect performance?

A: No. Packaging format affects only procurement and assembly logistics. Electrical and mechanical performance is identical regardless of packaging. Select based on your assembly process requirements and supplier availability.

Q: Can I use DF10S1 as a substitute if RoHS compliance is required?

A: DF10S1 does not specify RoHS status in the provided data. If RoHS3 compliance is mandatory for your application, select from parts with confirmed ROHS3 status: ABS10U, ABS10-HF, ABS10A-13, B1010S_R2_00001, DB107S (MDD), DBLS107G, DBLS107GH, DF10S-E3/77, or DF10SA-E3/77.

Q: Which substitute offers the best reverse leakage performance?

A: DBLS107G and DBLS107GH both specify 2 µA reverse leakage at 1000 V, compared to 5 µA for the DB107S. These parts provide superior leakage performance and are suitable for applications requiring minimal leakage current.
