Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB101S-HF is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Diode Type: Single Phase
• Technology: Standard

All substitute parts listed below meet these core electrical specifications and physical mounting requirements. Variations in reverse leakage current, packaging format (Tube vs. other configurations), and product status are noted but do not preclude functional substitution when electrical parameters align.

Engineering Selection Recommendations

DB101S-G (Comchip Technology)

The DB101S-G is a direct parametric equivalent to the DB101S-HF, sharing identical electrical specifications and physical packaging. However, this part carries an Obsolete product status. Selection of DB101S-G is appropriate only when existing inventory must be consumed or when legacy system maintenance requires exact part matching. The part is ROHS3 Compliant and carries MSL 1 (Unlimited) rating.

DF005S-G (Comchip Technology)

The DF005S-G meets all core electrical and mechanical requirements of the DB101S-HF. This part is also marked as Obsolete. The primary distinction is the supplier device package designation (DFS versus DBS), though both conform to the 4-SMD, Gull Wing physical specification. This part is ROHS3 Compliant with MSL 1 (Unlimited) rating. Current inventory stands at 6510 units.

DF005S-E3/45 (Vishay General Semiconductor - Diodes Division)

The DF005S-E3/45 is a cross-manufacturer substitute produced by Vishay. This part maintains Active product status and satisfies all electrical parameters required for DB101S-HF substitution. The reverse leakage current specification is superior at 5 µA @ 50 V compared to 10 µA @ 50 V for the main part, representing enhanced performance characteristics. The part is ROHS3 Compliant with MSL 1 (Unlimited) rating. Current inventory is 5644 units.

For new designs and ongoing procurement, the DF005S-E3/45 is the preferred selection due to its Active product status and availability from an established semiconductor manufacturer. For existing inventory management or legacy applications, DB101S-G and DF005S-G remain functionally equivalent alternatives.

Frequently Asked Questions (FAQ)

Q: Can DB101S-G be used as a direct replacement for DB101S-HF?

A: Yes. The DB101S-G meets all electrical specifications (50 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop) and physical mounting requirements (4-SMD, Gull Wing surface mount package) of the DB101S-HF. The primary consideration is that DB101S-G carries an Obsolete product status, whereas DB101S-HF is Active.

Q: What is the difference between DF005S-G and DF005S-E3/45?

A: Both parts satisfy the electrical and mechanical requirements of the DB101S-HF. The key differences are: (1) DF005S-E3/45 is manufactured by Vishay and maintains Active product status, while DF005S-G is manufactured by Comchip and is Obsolete; (2) DF005S-E3/45 specifies a reverse leakage current of 5 µA @ 50 V, compared to 10 µA @ 50 V for DF005S-G, indicating superior leakage performance.

Q: Are there package compatibility concerns between DBS and DFS supplier device packages?

A: No. Both DBS and DFS designations refer to the same physical 4-SMD, Gull Wing package configuration. The supplier device package designation is a manufacturer-specific nomenclature that does not affect mechanical or electrical compatibility in the specified application.

Q: Which substitute part should be selected for new production designs?

A: The DF005S-E3/45 is the recommended selection for new production designs. This part carries Active product status, is manufactured by Vishay (an established semiconductor supplier), maintains ROHS3 compliance, and demonstrates superior reverse leakage characteristics (5 µA @ 50 V).

Q: Are all substitute parts RoHS and REACH compliant?

A: All substitute parts listed (DB101S-G, DF005S-G, and DF005S-E3/45) are ROHS3 Compliant and REACH Unaffected. Compliance documentation should be verified with the respective manufacturer or authorized distributor for specific procurement batches.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
