HERA802G Equivalent & Substitute Parts

Part Overview

The HERA802G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 8 A average rectified current in a Through Hole TO-220AC package. This component is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate varying inventory availability across component distributors.

Substitute Part Grouping Explanation

Substitute parts for the HERA802G are identified based on strict parametric equivalence across the following critical electrical and mechanical specifications:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 8 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-2
• Supplier Device Package: TO-220AC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The UF801_T0_00001 manufactured by Panjit International Inc. meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent substitute for the HERA802G.

Parameter Comparison

*Equivalent: The UF801_T0_00001 exhibits lower reverse leakage current (1 µA vs. 10 µA), which represents improved performance within the same functional class.

Engineering Selection Recommendations

Both the HERA802G and UF801_T0_00001 are Active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on the following engineering criteria:

HERA802G (Taiwan Semiconductor Corporation):

• Primary choice when original manufacturer specification is required
• Current inventory: 753 Pcs New Original In Stock
• Established supply chain for Taiwan Semiconductor Corporation components

UF801_T0_00001 (Panjit International Inc.):

• Parametric equivalent with superior reverse leakage current performance (1 µA vs. 10 µA @ 100 V)
• Higher inventory availability: 3102 Pcs New Original In Stock
• Suitable for applications where improved leakage characteristics provide design margin
• Supplied in Tube packaging

Both parts satisfy identical electrical performance requirements, mechanical compatibility, and regulatory compliance. Selection may be driven by supply availability, inventory position, or design margin requirements for reverse leakage current.

Frequently Asked Questions (FAQ)

Q: Can the UF801_T0_00001 be used as a direct replacement for the HERA802G in existing designs?

A: Yes. The UF801_T0_00001 meets all specified electrical parameters (100 V reverse voltage, 8 A average rectified current, 1 V forward voltage, 50 ns reverse recovery time) and is packaged in the identical TO-220AC configuration. Both components operate across the same temperature range (-55°C to 150°C) and maintain RoHS3 compliance.

Q: What is the significance of the reverse leakage current difference between these parts?

A: The UF801_T0_00001 exhibits 1 µA reverse leakage current compared to 10 µA for the HERA802G, both measured at 100 V. This represents improved performance and may provide additional design margin in applications sensitive to leakage current. Both values remain within acceptable limits for general-purpose rectifier applications.

Q: Are there packaging differences between these substitute parts?

A: Both parts use the TO-220-2 package and TO-220AC supplier device package for Through Hole mounting. The primary packaging difference is that the HERA802G is supplied in standard packaging while the UF801_T0_00001 is supplied in Tube packaging. This does not affect electrical performance or mechanical compatibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the HERA802G and UF801_T0_00001 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What determines whether a part qualifies as a substitute for the HERA802G?

A: Substitution is based on matching all critical electrical parameters (reverse voltage, average rectified current, forward voltage, recovery time), identical mechanical packaging (TO-220AC Through Hole), and equivalent compliance status (RoHS3, Active product status). The UF801_T0_00001 satisfies all these criteria.
