B10S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The B10S-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage with 800 mA average rectified current. This component is classified as Active product status and is currently in stock with 1,150 units available. Bridge rectifiers in this specification class are used in power supply circuits, battery charging systems, and AC-to-DC conversion applications where single-phase rectification is required. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate component availability across different manufacturers and product lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B10S-HF are determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Peak Reverse Voltage: 1 kV
• Average Rectified Current: 800 mA
• Forward Voltage Drop: 1.1 V @ 800 mA
• Reverse Leakage Current: 5 µA @ 1000 V
• Operating Temperature Range: -55°C to 150°C
• Package / Case: TO-269AA, 4-BESOP (MBS)
• RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts match these parameters exactly. Substitution is valid when all electrical characteristics, thermal specifications, and mechanical package dimensions are identical. Manufacturer differences do not affect functional equivalence when parametric specifications are matched.

Parameter Comparison

Engineering Selection Recommendations

B10S-HF (Comchip Technology) is the primary selection for new designs. This part carries Active product status, ensuring long-term availability and manufacturer support. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing.

MB10S-13 (Diodes Incorporated) is a fully qualified substitute with identical electrical and mechanical specifications. This part is also Active status and maintains equivalent compliance certifications. Selection of MB10S-13 is appropriate when Comchip supply is constrained or when design requirements permit multi-source qualification.

B10S-G (Comchip Technology) is parametrically equivalent but carries Obsolete product status. This part should not be selected for new designs or long-term production applications. B10S-G may only be considered for legacy system repairs or end-of-life product support where existing inventory is available and supply continuity is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can B10S-HF be directly replaced with MB10S-13 in existing designs?

A: Yes. MB10S-13 is a parametric equivalent with identical electrical ratings (1 kV, 800 mA), forward voltage characteristics (1.1 V @ 800 mA), reverse leakage current (5 µA @ 1000 V), and thermal operating range (-55°C to 150°C). Both parts use the same TO-269AA, 4-BESOP package. No circuit modifications are required.

Q: Why is B10S-G listed as a substitute if it is Obsolete?

A: B10S-G meets all parametric requirements for functional equivalence. However, Obsolete status indicates the manufacturer has discontinued active production and support. B10S-G should only be used when existing inventory is available and supply chain continuity is not critical. For new designs and production applications, B10S-HF or MB10S-13 are the appropriate selections.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical across all substitute options.

Q: What is the significance of the TO-269AA, 4-BESOP package specification?

A: This package designation defines the physical form factor and pin configuration for surface mount assembly. All substitute parts use this identical package, ensuring PCB footprint compatibility and automated assembly compatibility without design changes.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts share the same operating temperature range of -55°C to 150°C junction temperature. Selection among B10S-HF, MB10S-13, or B10S-G does not affect thermal performance or temperature derating calculations.
