HER208-TP Equivalent & Substitute Parts

Part Overview

The HER208-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design and procurement requirements. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability in existing circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER208-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 2 A
• Reverse Recovery Time (trr): 75 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these electrical specifications and mechanical compatibility. Variations in packaging format (Cut Tape, Tape & Box) and manufacturer do not affect functional equivalence when electrical parameters and mounting characteristics remain identical.

Parameter Comparison

Engineering Selection Recommendations

HER208G-TP is the direct manufacturer equivalent from Micro Commercial Co in active product status. This part maintains identical electrical specifications and is supplied in Cut Tape packaging format. Selection of this part eliminates obsolescence risk while preserving all functional characteristics of the original HER208-TP design.

HER208G-AP is a parametric equivalent from Micro Commercial Co in active product status, supplied in Tape & Box packaging format. This part is suitable for applications where bulk packaging is preferred over cut tape format, with no electrical performance differentiation from HER208G-TP.

HER208G A0G is a parametric equivalent manufactured by Taiwan Semiconductor Corporation in active product status, supplied in Cut Tape packaging format. This part maintains all critical electrical specifications and is compatible with existing circuit designs. The manufacturer change from Micro Commercial Co to Taiwan Semiconductor Corporation does not affect functional equivalence. Capacitance at Vr, F specification differs at 20 pF versus 30 pF, which does not impact rectifier diode performance in standard applications.

All three substitute parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility with current procurement and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can HER208G-TP be used as a direct replacement for HER208-TP?

A: Yes. HER208G-TP is the direct manufacturer equivalent with identical electrical specifications, reverse voltage rating, forward current capability, and reverse recovery time. The primary difference is product status change from obsolete to active.

Q: What is the difference between HER208G-TP and HER208G-AP?

A: Both parts are manufactured by Micro Commercial Co and maintain identical electrical specifications. The difference is packaging format: HER208G-TP is supplied in Cut Tape (CT) format, while HER208G-AP is supplied in Tape & Box (TB) format. Selection depends on procurement and assembly requirements.

Q: Is HER208G A0G from Taiwan Semiconductor Corporation compatible with the original HER208-TP design?

A: Yes. HER208G A0G maintains all critical electrical parameters including voltage rating, current rating, forward voltage, and reverse recovery time. The manufacturer change does not affect functional compatibility. This part is suitable for direct substitution in circuit applications.

Q: Are there any package compatibility concerns between substitute parts?

A: All substitute parts use DO-15 or DO-204AC (DO-15) through-hole axial packages, which are mechanically and electrically compatible. HER208G A0G specifies DO-204AC (DO-15) as the supplier device package, which is equivalent to the DO-15 package used by other substitutes.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts (HER208G-TP, HER208G-AP, and HER208G A0G) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of the 75 ns reverse recovery time specification?

A: The 75 ns reverse recovery time is a critical parameter for fast recovery rectifier diodes. All substitute parts maintain this specification, ensuring equivalent switching performance and suitability for high-frequency rectification applications.

Q: Can inventory levels influence substitute part selection?

A: Inventory availability is a procurement consideration but does not affect electrical or mechanical compatibility. HER208G-TP has 29,729 pieces in stock, HER208G-AP has 1,176 pieces, and HER208G A0G has 7,896 pieces available. Selection should prioritize functional requirements first, with inventory as a secondary factor.
