Frequently Asked Questions (FAQ)

Q: What electrical parameters must match exactly for a part to substitute the DBLS107GHC1G?

A: The following parameters must match exactly: peak reverse voltage (1 kV), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), operating temperature range (-55°C to 150°C), diode type (single phase), and technology (standard). All substitute parts listed meet these requirements.

Q: Are there differences in reverse leakage current among the substitute parts?

A: Yes. The DBLS107GHC1G specifies 2 µA @ 1000 V reverse leakage. Substitute parts DB107S and DB107S-G specify 10 µA @ 1000 V. Substitute parts DF10S-E3/45, DF10SA-E3/45, and DI1010_T0_00001 specify 5 µA @ 1000 V. All values remain within acceptable operating parameters for the 1 kV, 1 A bridge rectifier classification.

Q: Can I use DB107S-G as a substitute?

A: DB107S-G meets all electrical and mechanical specifications. However, it carries Obsolete product status. Use this part only when supply constraints require and when long-term availability and future sourcing are not critical factors.

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

A: Both parts are electrically and mechanically equivalent. They share identical voltage, current, temperature, and package specifications. Selection between them depends on inventory availability and supply chain requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status and REACH Unaffected designation, matching the original DBLS107GHC1G specification.

Q: What is the moisture sensitivity level for all these parts?

A: All parts, including the original DBLS107GHC1G and all substitutes, carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions during storage and handling.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 1 kV, 1 A single-phase bridge rectifier function. They are mechanically compatible with the same 4-SMD Gull Wing footprint and can be used interchangeably in surface mount applications.

Q: Which substitute has the highest inventory availability?

A: DF10S-E3/45 (Vishay General Semiconductor - Diodes Division) has the highest inventory with 35,300 units in stock.
