DB107S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DB107S-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 1 A average rectified current in a 4-SMD surface mount package. The device is currently active in production and ROHS3 compliant.

Substitute parts are necessary when the DB107S-HF becomes unavailable from inventory, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Diode Type: Single Phase
Voltage - Peak Reverse (Max): 1 kV
Current - Average Rectified (Io): 1 A
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
Operating Temperature Range: -55°C ~ 150°C (TJ)
RoHS Status: ROHS3 Compliant

All substitute parts listed meet these requirements. Variations in reverse leakage current (5 µA versus 10 µA) and supplier device package designations (DBS, DFS, SDIP) do not affect functional equivalence within the specified electrical parameters.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

DB107S (MDD) is the preferred substitute, offering identical electrical specifications and active product status with the highest inventory availability (44,552 pcs).

DF10S-E3/45 and DF10SA-E3/45 (Vishay General Semiconductor - Diodes Division) are qualified substitutes with active status. These parts feature lower reverse leakage current (5 µA versus 10 µA), which represents improved performance within the specified parameter range.

DI1010_T0_00001 (Panjit International Inc.) is a qualified substitute with active status and lower reverse leakage current specification.

Secondary Substitute (Obsolete Status):

DB107S-G (Comchip Technology) is obsolete and should not be selected for new designs or long-term production applications. This part is listed for reference only in legacy system support scenarios.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 150°C).

Frequently Asked Questions (FAQ)

Q: Can DB107S-HF be replaced with DB107S-G?

A: DB107S-G is electrically equivalent but carries obsolete product status. It should not be used for new designs. Use active alternatives instead.

Q: What is the difference between DB107S (MDD) and DF10S-E3/45 (Vishay)?

A: Both are electrically qualified substitutes. The primary difference is reverse leakage current: DB107S specifies 10 µA @ 1000 V, while DF10S-E3/45 specifies 5 µA @ 1000 V. Both values are within acceptable operating parameters. Manufacturer and package designation (DBS versus DFS) differ, but mechanical compatibility remains identical.

Q: Are all substitute parts in the same physical package?

A: Yes. All listed parts use 4-SMD, Gull Wing surface mount packaging with identical mechanical dimensions and PCB footprint compatibility.

Q: Which substitute has the best inventory availability?

A: DB107S (MDD) has the highest inventory level at 44,552 pcs, followed by DF10S-E3/45 (Vishay) at 35,300 pcs.

Q: Do all substitutes meet RoHS compliance?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can DF10SA-E3/45 be used interchangeably with DF10S-E3/45?

A: Yes. Both are Vishay parts with identical electrical specifications, operating temperature range, and package configuration. Selection between them depends on inventory availability and supply chain requirements.
