DB105-G Bridge Rectifier Single Phase 600V 1A Equivalent & Substitute Parts

Part Overview

The DB105-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 600V peak reverse voltage and 1A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Bridge rectifiers in this voltage and current class are widely used in power supply circuits, battery chargers, and AC-to-DC conversion applications where single-phase rectification is required.

Substitute Part Grouping Explanation

Substitution eligibility for the DB105-G is determined by strict equivalence across the following critical parameters:

Diode Type: Single Phase
Technology: Standard
Voltage - Peak Reverse (Max): 600 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Through Hole
Package / Case: 4-EDIP (0.321", 8.15mm)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in reverse leakage current, manufacturer identity, and product status are noted but do not disqualify substitution eligibility when all primary parameters align.

Engineering Selection Recommendations

All substitute parts listed above are electrically and mechanically equivalent to the DB105-G and are suitable for direct replacement in applications requiring a 600V, 1A single-phase bridge rectifier in 4-EDIP through-hole packaging.

DF06-G is the preferred substitute when sourcing from Comchip Technology is required, as it maintains identical electrical specifications and RoHS3 compliance while offering active product status.

DB105-BP offers the highest inventory availability (25,756 pcs) among active alternatives and is manufactured by Micro Commercial Co with full RoHS3 compliance.

DB105 and DF05, both from SMC Diode Solutions, feature lower reverse leakage current (5 µA @ 600 V compared to 10 µA @ 600 V) and are suitable for applications where reduced leakage is beneficial. Note that DB105 carries REACH Affected status, while DF05 status is Vendor Undefined.

DF06 from HY Electronic (Cayman) Limited provides an alternative source with matching electrical specifications and active product status.

Frequently Asked Questions (FAQ)

Q: Can DB105-G be directly replaced with DF06-G? A: Yes. Both parts share identical electrical ratings (600V, 1A, 1.1V forward voltage), operating temperature range (-55°C to 150°C), and 4-EDIP package configuration. DF06-G is actively manufactured by Comchip Technology.

Q: What is the difference between DB105-G and DB105 from SMC Diode Solutions? A: The primary difference is reverse leakage current: DB105-G specifies 10 µA @ 600V, while DB105 specifies 5 µA @ 600V. All other electrical and mechanical parameters are identical. The lower leakage of DB105 may provide improved performance in low-current or high-impedance circuit applications.

Q: Are all substitute parts in the same physical package? A: Yes. All listed substitutes use the 4-EDIP (0.321", 8.15mm) through-hole package, ensuring mechanical compatibility with existing PCB layouts designed for DB105-G.

Q: Why is DB105-G classified as obsolete? A: Obsolete status indicates the part is no longer manufactured by Comchip Technology. Active equivalent alternatives are available from multiple manufacturers with identical performance specifications.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts are ROHS3 Compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: Which substitute offers the best inventory availability? A: DB105-BP from Micro Commercial Co currently has the highest inventory level at 25,756 pcs in stock.
