HER605GP-TP Equivalent & Substitute Parts

Part Overview

The HER605GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 6 A average rectified current in an R-6 axial through-hole package. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Identification of equivalent and substitute parts is necessary for applications requiring continued support of legacy designs or when primary inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HER605GP-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 6 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: R-6, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant

All substitute parts listed meet these core electrical and mechanical requirements, ensuring functional compatibility in applications designed for the HER605GP-TP. Variations in secondary parameters such as reverse recovery time (trr) and junction capacitance do not preclude substitution when primary ratings are identical.

Engineering Selection Recommendations

FR604GP-TP (Micro Commercial Co)

The FR604GP-TP is an active product from the same manufacturer as the HER605GP-TP. It maintains identical electrical ratings for voltage, current, and forward voltage drop. The primary difference is an increased reverse recovery time of 150 ns compared to the HER605GP-TP's 50 ns, and a higher junction capacitance of 150 pF versus 100 pF. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating. This substitute is suitable for applications where the faster recovery characteristics of the original part are not critical to circuit performance.

FR604T-G (Comchip Technology)

The FR604T-G is an active product from an alternative manufacturer and provides equivalent electrical performance to the HER605GP-TP across all critical parameters. It matches the original part's reverse recovery time of 50 ns and junction capacitance of 100 pF, offering the closest electrical behavior to the HER605GP-TP. ROHS3 compliance and unlimited moisture sensitivity rating are maintained. This substitute is appropriate for applications requiring performance characteristics identical to the original specification.

Both substitute parts are actively manufactured and carry current product status, providing supply continuity for legacy designs.

Frequently Asked Questions (FAQ)

Q: Can FR604GP-TP be used as a direct replacement for HER605GP-TP?

A: Yes. The FR604GP-TP meets all critical electrical parameters: 400 V reverse voltage rating, 6 A average rectified current, 1.3 V forward voltage drop at 6 A, and identical package configuration (R-6 axial through-hole). The increased reverse recovery time (150 ns vs. 50 ns) and junction capacitance (150 pF vs. 100 pF) do not prevent substitution in standard rectification applications.

Q: What is the difference between FR604GP-TP and FR604T-G?

A: Both parts share identical electrical ratings and package specifications. The primary distinction is manufacturer: FR604GP-TP is from Micro Commercial Co, while FR604T-G is from Comchip Technology. The FR604T-G matches the HER605GP-TP's reverse recovery time (50 ns) and junction capacitance (100 pF) more closely than the FR604GP-TP.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitute parts use R-6 axial through-hole packaging, identical to the HER605GP-TP. They are supplied in Tape & Reel (TR) format and are compatible with standard PCB assembly processes for through-hole components.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both FR604GP-TP and FR604T-G are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the HER605GP-TP's compliance profile. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: Why is the HER605GP-TP marked as Not For New Designs?

A: This designation indicates the part has been superseded by the manufacturer. The FR604GP-TP and FR604T-G represent the active product alternatives. For new designs, selection from the active product line is recommended to ensure long-term supply availability and manufacturer support.

Q: What is the operating temperature range for all parts?

A: All parts, including the HER605GP-TP and both substitutes, operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications.
