Substitute Part Grouping Explanation

Substitute parts for the DBLS107G C1G are qualified based on the following criteria:

Primary Electrical Parameters:

Voltage - Peak Reverse (Max): 1 kV
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
Operating Temperature: -55°C ~ 150°C (TJ)

Mechanical Parameters:

Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing

Compliance Parameters:

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in reverse leakage current (ranging from 2 µA to 10 µA @ 1000 V) remain within acceptable operational limits for this component category. Packaging format variations (tube versus standard) do not affect functional equivalence.

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

DB107S (MDD), DB107S-HF (Comchip Technology), DF10S-E3/45 (Vishay), DF10SA-E3/45 (Vishay), and DI1010_T0_00001 (Panjit International) are all in active product status. These parts are suitable for new design implementations and long-term supply chain planning.

Obsolete Status Parts (Not Recommended):

DB107S-G (Comchip Technology) carries obsolete product status and should not be selected for new applications. This part is retained in the equivalency list for reference only in legacy system maintenance scenarios.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original DBLS107G C1G specifications. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Reverse Leakage Considerations:

The DBLS107G C1G exhibits 2 µA reverse leakage at 1000 V. Substitute parts from Vishay (DF10S-E3/45, DF10SA-E3/45) and Panjit (DI1010_T0_00001) demonstrate 5 µA reverse leakage, while MDD (DB107S) and Comchip (DB107S-G, DB107S-HF) exhibit 10 µA reverse leakage. All values remain within acceptable operational parameters for this component category.

Frequently Asked Questions (FAQ)

Q: Can DB107S replace DBLS107G C1G in existing applications?

A: Yes. DB107S maintains identical electrical ratings (1 kV, 1 A) and mechanical specifications (4-SMD, Gull Wing surface mount package). Both parts are RoHS3 compliant with MSL Level 1 rating. The higher reverse leakage current (10 µA versus 2 µA) does not affect functional compatibility in standard bridge rectifier applications.

Q: What is the difference between DF10S-E3/45 and DF10SA-E3/45?

A: Both parts are manufactured by Vishay and share identical electrical specifications (1 kV, 1 A) and mechanical packaging (4-SMD, Gull Wing). Both are in active product status with 5 µA reverse leakage current. The parts are functionally equivalent for substitution purposes.

Q: Why is DB107S-G listed if it is obsolete?

A: DB107S-G is included for reference in legacy system maintenance and repair scenarios where the original part specification must be maintained. For new designs, active status alternatives such as DB107S-HF should be selected.

Q: Are packaging format differences (tube versus standard) significant for substitution?

A: Packaging format variations do not affect electrical or mechanical compatibility. Tube packaging is a supply format consideration only. Component selection should prioritize active product status and electrical parameter equivalence.

Q: Which substitute part has the lowest reverse leakage current?

A: DF10S-E3/45, DF10SA-E3/45, and DI1010_T0_00001 all exhibit 5 µA reverse leakage current at 1000 V, which is lower than the original DBLS107G C1G (2 µA) and other alternatives. These parts are suitable for applications requiring minimal leakage characteristics.

Q: Can I use DI1010_T0_00001 as a direct replacement?

A: Yes. DI1010_T0_00001 maintains all critical electrical parameters (1 kV, 1 A, 1.1 V forward voltage) and mechanical specifications (4-SMD, Gull Wing surface mount). The part is in active status with RoHS3 compliance and MSL Level 1 rating.
