HER602GP-AP Equivalent & Substitute Parts

Part Overview

The HER602GP-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 6 A average rectified current. The device features fast recovery characteristics with a reverse recovery time of 50 ns and is housed in an R-6 axial through-hole package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical ratings and mechanical compatibility are maintained across the specified parameter range, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the HER602GP-AP is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 6 A
Package / Case: R-6, Axial
Mounting Type: Through Hole
RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

Voltage - Forward (Vf) (Max) @ If: Substitute must not exceed 1.1 V @ 6 A
Reverse Recovery Time (trr): Substitute may differ from 50 ns (fast recovery vs. standard recovery acceptable)
Operating Temperature - Junction (Max): Substitute minimum of 125°C acceptable; 150°C preferred
Current - Reverse Leakage @ Vr: 10 µA @ 100 V (equivalent specification)
Capacitance @ Vr, F: 100 pF @ 4V, 1MHz (equivalent specification)

The substitute part 6A01B-G, manufactured by Comchip Technology, meets all mandatory equivalence criteria and is therefore classified as a direct substitute.

Engineering Selection Recommendations

Primary Selection: HER602GP-AP

The HER602GP-AP is the specified component and remains the primary selection. It is Active product status, RoHS3 compliant, and offers the extended operating temperature range of -55°C to 150°C with fast recovery characteristics (50 ns reverse recovery time).

Substitute Selection: 6A01B-G

The 6A01B-G is a valid substitute when HER602GP-AP availability is constrained. Both components are Active product status and RoHS3 compliant. The 6A01B-G exhibits a lower forward voltage drop (1.0 V vs. 1.1 V @ 6 A), which may provide marginal efficiency benefits in certain applications. However, the 6A01B-G operates at a reduced maximum junction temperature (125°C vs. 150°C) and employs standard recovery characteristics rather than fast recovery. These differences must be evaluated against specific application thermal and switching requirements.

Both components are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can the 6A01B-G directly replace the HER602GP-AP in all applications?

A: The 6A01B-G is mechanically and electrically compatible for applications operating within -55°C to 125°C junction temperature range. Applications requiring operation above 125°C or demanding fast recovery switching characteristics (≤ 50 ns) must retain the HER602GP-AP.

Q: What is the significance of the recovery speed difference between these parts?

A: The HER602GP-AP features fast recovery (50 ns reverse recovery time), while the 6A01B-G employs standard recovery (> 500 ns). Fast recovery diodes exhibit reduced switching losses and are preferred in high-frequency switching applications. Standard recovery diodes are suitable for lower-frequency rectification circuits.

Q: Are both parts suitable for RoHS3 applications?

A: Yes. Both HER602GP-AP and 6A01B-G are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance compliance.

Q: What is the package compatibility between these parts?

A: Both components utilize the R-6 axial through-hole package. Mechanical fit and PCB layout compatibility are identical. No board redesign is required for substitution.

Q: How do the forward voltage characteristics compare?

A: The 6A01B-G exhibits a lower maximum forward voltage (1.0 V @ 6 A) compared to the HER602GP-AP (1.1 V @ 6 A). This 0.1 V difference results in reduced power dissipation in the substitute part under full-load conditions.

Q: Are there inventory considerations for these parts?

A: HER602GP-AP inventory is 824 pieces. 6A01B-G inventory is 714 pieces. Both are listed as new original stock.
