DF2005ST-G Equivalent & Substitute Parts

Part Overview

The DF2005ST-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 50 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part is housed in a 4-SMD, Gull Wing surface mount package and complies with ROHS3 and REACH Unaffected standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF2005ST-G are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

Two substitute parts meet these criteria: DF2005S-G (manufacturer-recommended equivalent from Comchip Technology) and DB201S (parametric equivalent from SMC Diode Solutions). Both maintain identical electrical performance specifications and physical form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

DF2005S-G is the primary substitute for DF2005ST-G. Both parts are manufactured by Comchip Technology and share identical electrical and mechanical specifications. The DF2005S-G maintains active product status, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 standards and are REACH Unaffected.

DB201S is a parametric equivalent manufactured by SMC Diode Solutions. All critical electrical parameters match the original specification. The DB201S exhibits lower reverse leakage current (5 µA versus 10 µA at 50 V), representing improved performance characteristics. However, DB201S carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. The part is available in Tape & Reel packaging, differing from the original Tube packaging of DF2005S-G.

Selection between DF2005S-G and DB201S depends on regulatory requirements and supply chain preferences. For REACH-sensitive applications, DF2005S-G is the appropriate choice. For applications where REACH compliance is not a constraint, DB201S offers superior reverse leakage performance and higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DF2005S-G directly replace DF2005ST-G in existing designs?

A: Yes. DF2005S-G is electrically and mechanically equivalent to DF2005ST-G. Both parts share identical voltage ratings (50 V peak reverse), current ratings (2 A average rectified), forward voltage characteristics (1.1 V @ 2 A), operating temperature range (-55°C ~ 150°C), and 4-SMD Gull Wing package configuration. The primary difference is product status: DF2005ST-G is obsolete while DF2005S-G is active.

Q: What is the difference between DF2005S-G and DB201S?

A: Both parts are electrically equivalent across all primary specifications: 50 V peak reverse voltage, 2 A average rectified current, 1.1 V forward voltage at 2 A, and -55°C ~ 150°C operating temperature. The DB201S exhibits lower reverse leakage current (5 µA versus 10 µA at 50 V). The parts differ in manufacturer (Comchip Technology versus SMC Diode Solutions), REACH status (Unaffected versus Affected), and packaging format (Tube versus Tape & Reel).

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use identical 4-SMD, Gull Wing surface mount packages. PCB footprints and assembly processes remain unchanged. Packaging format differences (Tube for DF2005S-G, Tape & Reel for DB201S) affect procurement and handling only, not component installation.

Q: Which substitute should be selected for REACH-compliant applications?

A: DF2005S-G is REACH Unaffected and is the appropriate selection for applications requiring REACH compliance. DB201S is REACH Affected and requires additional compliance verification before use in REACH-regulated applications.

Q: What is the reverse leakage current difference between DB201S and the original part?

A: DB201S specifies 5 µA reverse leakage at 50 V, compared to 10 µA for DF2005ST-G and DF2005S-G. This represents improved leakage performance in the DB201S, which may be beneficial for applications sensitive to reverse current characteristics.
