HER202-TP Equivalent & Substitute Parts

Part Overview

The HER202-TP is a general-purpose rectifier diode rated for 100 V DC reverse voltage and 2 A average rectified current in a through-hole DO-15 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Suitable alternatives maintain the core electrical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER202-TP is determined by the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 2 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns

Physical and Environmental Specifications:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Parametric Equivalent: Parts that match all critical electrical specifications (voltage, current, recovery time) and maintain identical forward voltage characteristics. These parts are direct functional replacements.

Similar Substitute: Parts that maintain voltage and temperature ratings but differ in current capacity or recovery characteristics. These parts are suitable for applications with reduced current requirements or where recovery speed is not critical.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements):

The HER202G (Taiwan Semiconductor Corporation) and UF201G_R2_00001 (Panjit International Inc.) are parametric equivalents to the HER202-TP. Both parts maintain identical electrical specifications including 100 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, fast recovery characteristics with 50 ns reverse recovery time, and -55°C to 150°C operating temperature range. Both are ROHS3 compliant and carry active product status. The HER202G is available in DO-204AC (DO-15) package configuration, while the UF201G_R2_00001 is supplied in Tape & Reel packaging. Selection between these two should be based on packaging requirements and supplier availability.

Similar Substitute (Reduced Current Application):

The 1N5392GHB0G (Taiwan Semiconductor Corporation) is a similar substitute suitable for applications where the current requirement does not exceed 1.5 A. This part maintains the 100 V reverse voltage rating and -55°C to 150°C operating temperature range. However, it differs in three key aspects: current capacity is reduced to 1.5 A, forward voltage is 1.1 V at 1.5 A, and recovery speed is standard (>500ns) rather than fast recovery. This part carries AEC-Q101 automotive qualification and active product status. Use this substitute only when circuit design permits reduced current capacity and standard recovery speed.

Frequently Asked Questions (FAQ)

Q: Can the HER202G directly replace the HER202-TP in all applications?

A: Yes. The HER202G maintains all critical electrical parameters: 100 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, 50 ns reverse recovery time, and identical operating temperature range. Both are ROHS3 compliant. The primary difference is product status (HER202G is active versus HER202-TP obsolete) and package variant (DO-204AC versus DO-15 designation, though both are axial through-hole configurations).

Q: What is the difference between the HER202G and UF201G_R2_00001?

A: Both are parametric equivalents with identical electrical specifications. The primary difference is packaging: HER202G is supplied in standard packaging, while UF201G_R2_00001 is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements. The UF201G_R2_00001 exhibits lower reverse leakage current (1 µA versus 5 µA at 100 V).

Q: When should the 1N5392GHB0G be used instead of the parametric equivalents?

A: The 1N5392GHB0G should be used only when circuit design permits reduced current capacity (1.5 A maximum versus 2 A) and standard recovery speed (>500ns versus 50 ns fast recovery). This part is suitable for lower-current applications and carries automotive qualification (AEC-Q101). Do not use this substitute in circuits requiring 2 A current capacity or fast recovery characteristics.

Q: Are all substitute parts compatible with the original DO-15 package footprint?

A: Yes. All substitute parts are specified for DO-204AC, DO-15, Axial package configuration and are compatible with through-hole PCB layouts designed for the HER202-TP. Physical dimensions and pin spacing are equivalent across all listed parts.

Q: What compliance certifications apply to these substitute parts?

A: All listed parts are ROHS3 compliant. The 1N5392GHB0G carries additional AEC-Q101 automotive qualification. The UF201G_R2_00001 and HER202G carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Is there a difference in moisture sensitivity between the main part and substitutes?

A: No. All parts, including the HER202-TP and all substitutes, carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.
