B6S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The B6S-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 600 V peak reverse voltage and 800 mA average rectified current. This surface mount component operates across a temperature range of -55°C to 150°C and is packaged in TO-269AA, 4-BESOP configuration. The B6S-HF maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when equivalent electrical and mechanical specifications allow for direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B6S-HF is determined by matching the following critical parameters:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 800 mA
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 800 mA
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Package / Case: TO-269AA, 4-BESOP
• Mounting Type: Surface Mount
• Diode Type: Single Phase
• Technology: Standard

The B6S-G meets all electrical and mechanical substitution criteria. Packaging differences (Cut Tape & Digi-Reel® versus Tape & Reel) do not affect functional equivalence and represent alternative supply formats for the same component specification.

Parameter Comparison

Engineering Selection Recommendations

The B6S-HF is the preferred selection for new designs due to its Active product status. This ensures ongoing manufacturer support, consistent supply chain availability, and compliance with current industry standards.

The B6S-G is electrically and mechanically equivalent and may be used as a direct substitute where inventory or supply constraints require alternative sourcing. However, the Obsolete product status of B6S-G indicates limited future availability and potential discontinuation of manufacturing support. Selection of B6S-G should be limited to replacement or repair applications where existing stock is available.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). Packaging format differences do not affect circuit functionality or PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can B6S-G replace B6S-HF in existing designs?

A: Yes. B6S-G meets all electrical and mechanical specifications required for direct substitution. The components are functionally identical across voltage, current, temperature, and package parameters.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Both packaging formats contain the same component. Tape & Reel (TR) provides continuous reel supply suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides smaller quantity formats. Packaging format does not affect component performance or PCB mounting.

Q: Why is B6S-G listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. While existing inventory may be available, future availability is not guaranteed. For new designs, B6S-HF (Active status) is recommended.

Q: Are there any compliance or certification differences between B6S-HF and B6S-G?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Regulatory and environmental compliance is identical.

Q: What is the operating temperature range for these bridge rectifiers?

A: Both B6S-HF and B6S-G operate across -55°C to 150°C junction temperature (TJ), suitable for industrial and commercial applications across extended temperature environments.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical package configuration (TO-269AA, 4-BESOP) and surface mount mounting type ensure direct PCB compatibility without layout or assembly modifications.
