Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER602GP-TP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 6 A
• Package / Case: R-6, Axial
• Mounting Type: Through Hole

Compatible Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Substitute must not exceed 1.1 V @ 6 A
• Reverse Recovery Time (trr): Substitute may operate at Standard Recovery (>500 ns) or Fast Recovery (≤500 ns)
• Operating Temperature - Junction: Substitute must support minimum -55°C to 125°C range
• Current - Reverse Leakage @ Vr: Substitute must not exceed 10 µA @ 100 V
• Capacitance @ Vr, F: Substitute must not exceed 100 pF @ 4V, 1MHz

The substitute part 6A01B-G manufactured by Comchip Technology meets all mandatory matching parameters and operates within all compatible variation parameters, establishing it as a valid electrical and mechanical equivalent.

Engineering Selection Recommendations

Primary Substitute: 6A01B-G (Comchip Technology)

The 6A01B-G is the qualified substitute for the HER602GP-TP based on electrical and mechanical equivalence. Selection of this substitute is supported by the following factors:

1. Electrical Equivalence: Both components share identical voltage ratings (100 V DC reverse), current ratings (6 A average rectified), reverse leakage characteristics (10 µA @ 100 V), and junction capacitance (100 pF @ 4V, 1MHz).

2. Mechanical Compatibility: Both components utilize the R-6 axial through-hole package, ensuring direct physical and electrical compatibility in existing PCB layouts and circuit designs.

3. Compliance Status: The 6A01B-G maintains ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original component's regulatory and environmental specifications.

4. Product Status: The 6A01B-G carries Active product status, ensuring continued availability and supply chain support, whereas the HER602GP-TP is designated Not For New Designs.

5. Forward Voltage Advantage: The 6A01B-G exhibits a lower maximum forward voltage (1 V @ 6 A) compared to the HER602GP-TP (1.1 V @ 6 A), resulting in reduced power dissipation in rectification applications.

Operational Consideration: The 6A01B-G operates at Standard Recovery speed (>500 ns), whereas the HER602GP-TP is classified as Fast Recovery (≤500 ns). This difference does not preclude substitution in general-purpose rectification applications but may affect performance in high-frequency switching circuits where fast recovery characteristics are critical to circuit operation.

Temperature Range Consideration: The 6A01B-G supports a maximum junction temperature of 125°C, compared to the HER602GP-TP maximum of 150°C. Applications requiring sustained operation above 125°C require thermal analysis to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 6A01B-G directly replace the HER602GP-TP in existing designs?

A: Yes. Both components share identical voltage ratings (100 V), current ratings (6 A), and R-6 axial through-hole package specifications. Direct physical and electrical substitution is supported without PCB modification.

Q: What is the significance of the different recovery speeds (Fast vs. Standard)?

A: The HER602GP-TP operates at Fast Recovery (≤500 ns), while the 6A01B-G operates at Standard Recovery (>500 ns). In general-purpose rectification applications operating at line frequency (50/60 Hz), this difference has negligible impact. In high-frequency switching applications (>10 kHz), the slower recovery time of the 6A01B-G may increase switching losses and heat generation. Circuit performance analysis is required for applications with switching frequencies above 1 kHz.

Q: Does the lower forward voltage of the 6A01B-G provide a benefit?

A: Yes. The 6A01B-G forward voltage maximum is 1 V @ 6 A, compared to 1.1 V @ 6 A for the HER602GP-TP. This 0.1 V reduction decreases power dissipation in the diode, resulting in lower heat generation and improved circuit efficiency. This benefit is particularly significant in high-current rectification applications.

Q: Are there compliance or regulatory differences between these components?

A: No. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080. Regulatory and environmental compliance is equivalent.

Q: What is the maximum junction temperature difference, and does it affect substitution?

A: The HER602GP-TP supports -55°C to 150°C, while the 6A01B-G supports -55°C to 125°C. The 25°C reduction in maximum temperature does not affect most industrial and consumer applications operating below 125°C. Applications requiring sustained operation above 125°C require thermal design verification to confirm the 6A01B-G operates within specified limits.

Q: Is the 6A01B-G available in the same packaging format?

A: The 6A01B-G is supplied in Bulk packaging, whereas the HER602GP-TP is supplied in Tape & Reel (TR) format. Both components use the R-6 axial through-hole package. Bulk packaging does not affect electrical or mechanical compatibility; it reflects only the supplier's distribution format.

Q: Why is the HER602GP-TP marked "Not For New Designs"?

A: This designation indicates the component has reached end-of-life status and is no longer recommended for new product development. The 6A01B-G, carrying Active product status, is the recommended substitute for ongoing production and new design implementations.
