DB105SP-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DB105SP-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 600 V peak reverse voltage and 1 A average rectified current in a surface mount DBS package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The DB105SP-HF operates across a temperature range of -55°C to 150°C and is suitable for applications requiring standard bridge rectification in compact surface mount configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB105SP-HF is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

• Voltage Rating: Peak reverse voltage of 600 V
• Current Rating: Average rectified current of 1 A
• Forward Voltage: Maximum 1.1 V at 1 A
• Reverse Leakage: 10 µA at 600 V
• Temperature Range: -55°C to 150°C
• Package Type: 4-SMD, Gull Wing surface mount configuration
• Diode Configuration: Single-phase bridge rectifier with standard technology

The primary substitute, DB105S-HF, is manufactured by Comchip Technology and maintains identical electrical specifications and package configuration. This part is classified as active, providing long-term availability and supply chain continuity. Additional cross-reference parts (DF06S-G, DF06S-E3/45, DB105S-G, DF06S) are listed as secondary equivalents and share the same electrical and mechanical parameters.

Engineering Selection Recommendations

The DB105S-HF is the recommended primary substitute for the obsolete DB105SP-HF. Both components are manufactured by Comchip Technology and provide identical electrical performance and mechanical compatibility. The DB105S-HF maintains active product status, ensuring availability for current and future production requirements.

Selection of DB105S-HF eliminates obsolescence risk while preserving circuit functionality. The part is classified under ECCN EAR99 and HTSUS 8541.10.0080, consistent with the original component. Current inventory of 808 units supports immediate procurement needs.

Secondary cross-reference parts (DF06S-G, DF06S-E3/45, DB105S-G, DF06S) are electrically and mechanically equivalent and may be selected based on supplier availability and lead time considerations. All substitute options maintain the same 600 V peak reverse voltage, 1 A average rectified current, and 4-SMD Gull Wing package configuration.

Frequently Asked Questions (FAQ)

Q: Can DB105S-HF be used as a direct replacement for DB105SP-HF?

A: Yes. The DB105S-HF provides identical electrical specifications and package configuration. Both components feature 600 V peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, and operate across -55°C to 150°C. The DBS package and 4-SMD Gull Wing footprint are identical, enabling direct PCB substitution.

Q: What is the difference between DB105SP-HF and DB105S-HF?

A: The primary difference is product status. DB105SP-HF is classified as obsolete, while DB105S-HF is active. All electrical parameters, thermal characteristics, and mechanical specifications are equivalent. The suffix designation reflects manufacturing or packaging variations that do not affect electrical performance.

Q: Are the secondary cross-reference parts (DF06S-G, DF06S-E3/45, DB105S-G, DF06S) suitable replacements?

A: Yes. All listed cross-reference parts maintain the same electrical ratings (600 V, 1 A), forward voltage characteristics (1.1 V @ 1 A), reverse leakage (10 µA @ 600 V), and surface mount DBS package configuration. Selection among these options depends on supplier availability and procurement lead times.

Q: Does the operating temperature range differ between the main part and substitutes?

A: No. Both DB105SP-HF and DB105S-HF operate across -55°C to 150°C. The DB105S-HF specification includes the notation (TJ) to indicate junction temperature, which is standard engineering documentation practice and does not alter the functional temperature range.

Q: What packaging considerations apply to this substitution?

A: All substitute parts use identical 4-SMD Gull Wing surface mount packaging in the DBS supplier device package. PCB footprints, solder pad configurations, and assembly processes remain unchanged. No design modifications are required for component substitution.

Q: Is inventory availability a factor in selecting a substitute?

A: DB105S-HF currently has 808 units in stock, providing adequate supply for production requirements. Secondary cross-reference parts should be evaluated based on individual supplier inventory levels and lead time commitments.
