DB106 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DB106 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 800 V peak reverse voltage and 1 A average rectified current. This component is designed for through-hole mounting in 4-EDIP (0.321", 8.15mm) package configuration and operates across -55°C to 150°C junction temperature range. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary DB106 is unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits operation within the electrical and mechanical parameters of equivalent alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB106 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• 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)

Allowable Variation Parameters:

• Voltage - Peak Reverse (Max): Equal to or greater than 800 V
• Current - Reverse Leakage @ Vr: Equal to or less than 5 µA @ rated voltage

The DF06 qualifies as a parametric equivalent despite a lower peak reverse voltage rating (600 V versus 800 V), as it maintains all other critical electrical and mechanical parameters. The DB106-BP qualifies as a direct equivalent with identical voltage and current ratings, differing only in manufacturer and reverse leakage specification.

Parameter Comparison

Engineering Selection Recommendations

DB106-BP (Micro Commercial Co): This substitute provides identical electrical specifications to the DB106, including 800 V peak reverse voltage rating and 1 A current capacity. Both components share ROHS3 compliance, unlimited MSL rating, and identical package geometry. The DB106-BP maintains Active product status with higher inventory availability (5744 units). Selection of DB106-BP introduces no electrical or mechanical trade-offs relative to the primary DB106.

DF06 (HY Electronic): This substitute operates at 600 V peak reverse voltage, representing a 200 V reduction from the DB106 specification. All other electrical parameters remain equivalent: 1 A average rectified current, 1.1 V forward voltage drop, and -55°C to 150°C operating range. The DF06 maintains identical through-hole mounting configuration and 4-EDIP package dimensions. ROHS3 compliance and unlimited MSL are preserved. Selection of DF06 is appropriate only for applications where the circuit design operates below 600 V peak reverse voltage.

Frequently Asked Questions (FAQ)

Q: Can the DF06 directly replace the DB106 in all applications?

A: The DF06 is electrically and mechanically compatible with the DB106 only in applications where the peak reverse voltage does not exceed 600 V. If the circuit design requires 800 V reverse voltage capability, the DF06 is not suitable. Verify the actual reverse voltage stress in your application before substitution.

Q: What is the difference between DB106 and DB106-BP?

A: The DB106-BP is manufactured by Micro Commercial Co while the DB106 is manufactured by SMC Diode Solutions. Both components share identical electrical ratings (800 V, 1 A), forward voltage characteristics, and package configuration. The DB106-BP exhibits slightly higher reverse leakage current (10 µA versus 5 µA at rated voltage). Both maintain ROHS3 compliance and Active product status.

Q: Are all substitute parts available in the same packaging format?

A: Yes. The DB106, DF06, and DB106-BP all utilize 4-EDIP (0.321", 8.15mm) through-hole package configuration. Physical board layout and mounting procedures remain identical across all three components.

Q: What compliance certifications apply to these substitute parts?

A: All three components (DB106, DF06, and DB106-BP) maintain ROHS3 compliance. The DB106 and DB106-BP are REACH Affected or REACH Unaffected respectively, while the DF06 carries Vendor Undefined REACH status. All components are classified under ECCN EAR99 where applicable.

Q: How do reverse leakage specifications affect component selection?

A: The DB106 specifies 5 µA reverse leakage at 800 V, while both DF06 and DB106-BP specify 10 µA at their respective rated voltages. Higher reverse leakage increases standby power dissipation and may affect circuit performance in high-impedance applications. Verify that your circuit design tolerates the specified leakage current before substitution.
