DFB2010 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DFB2010 is a single-phase bridge rectifier manufactured by onsemi, rated for 100 V peak reverse voltage and 20 A average rectified current. This component is classified as "Not For New Designs," making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and legacy system support. The through-hole TS-6P package provides mechanical compatibility with established PCB layouts. Equivalent parts with identical or superior electrical characteristics and active product status are available from alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the DFB2010 is determined by strict equivalence across the following parameters:

Diode Type: Single Phase
Technology: Standard
Voltage - Peak Reverse (Max): 100 V
Current - Average Rectified (Io): 20 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 20 A
Operating Temperature Range: -55°C to 150°C (TJ)
Mounting Type: Through Hole
Package / Case: TS-6P or mechanically equivalent 4-SIP variants
RoHS Status: ROHS3 Compliant

All identified substitute parts meet these core electrical and mechanical requirements. Variations in leakage current, MSL rating, and product status are noted but do not disqualify substitution based on functional equivalence.

Engineering Selection Recommendations

GBJ2001 (SMC Diode Solutions): This part is electrically equivalent with active product status. The 4-ESIP package differs from the TS-6P, requiring PCB layout verification for mechanical fit. Lower reverse leakage current (5 µA @ 100 V) provides improved performance margin. ROHS3 compliance and active manufacturing status support long-term availability.

TS20P02G (Taiwan Semiconductor Corporation): Direct parametric equivalent with identical TS-6P package geometry, ensuring mechanical interchangeability without PCB modification. Active product status and ROHS3 compliance provide supply chain continuity. Suitable for direct replacement in existing designs.

TS20P02GH (Taiwan Semiconductor Corporation): Functionally identical to TS20P02G with additional automotive-grade qualification (AEC-Q101). This variant is appropriate for applications requiring automotive-level reliability and traceability. Package and electrical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can GBJ2001 be used as a direct replacement for DFB2010?

A: GBJ2001 meets all electrical requirements (100 V, 20 A, 1.1 V forward drop, -55 to 150°C operating range). However, the 4-ESIP package differs from the TS-6P package. Physical fit on the PCB must be verified before substitution.

Q: What is the difference between TS20P02G and TS20P02GH?

A: Both parts are electrically and mechanically identical. TS20P02GH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. Selection depends on application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DFB2010, GBJ2001, TS20P02G, and TS20P02GH are all ROHS3 compliant.

Q: Why is DFB2010 marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. TS20P02G, TS20P02GH, and GBJ2001 are active products with ongoing manufacturer support and are preferred for new applications.

Q: Do package differences affect electrical performance?

A: No. Package differences (TS-6P versus 4-ESIP) are mechanical only. Electrical characteristics remain equivalent. PCB layout compatibility must be assessed independently.

Q: What is the inventory status of substitute parts?

A: GBJ2001: 901 pcs; TS20P02G: 886 pcs; TS20P02GH: 1054 pcs. All are available as new original stock.
