Substitute Part Grouping Explanation

Substitution of the obsolete HER608-TP is determined by electrical and mechanical parameter equivalence. The substitute part must satisfy the following criteria:

Electrical Parameters (Critical for Function):

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 6 A
• Reverse Recovery Time (trr): 75 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 1000 V
• Capacitance @ Vr, F: 65 pF @ 4V, 1MHz
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Critical for Installation):

• Mounting Type: Through Hole
• Package / Case: R-6, Axial

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The HER608GP-TP meets all electrical and mechanical equivalence criteria and is classified as an active product, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The HER608GP-TP is the direct functional equivalent of the HER608-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications, mechanical form factor, and compliance certifications. The primary distinction is product status: the HER608-TP is obsolete, while the HER608GP-TP is active and maintains current manufacturing support.

Selection of the HER608GP-TP for new designs or replacement procurement is appropriate based on:

1. Electrical Equivalence: All voltage, current, and switching characteristics are identical.
2. Mechanical Compatibility: Both parts use the R-6 axial through-hole package, ensuring direct board-level substitution without layout modification.
3. Compliance Alignment: Both parts meet ROHS3 requirements and carry MSL 1 rating, supporting identical supply chain and storage protocols.
4. Active Product Status: The HER608GP-TP is actively manufactured, ensuring long-term availability and supply continuity.

The only operational difference is packaging format: the HER608-TP is supplied in bulk, while the HER608GP-TP is supplied in Tape & Reel format. This distinction affects procurement and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the HER608GP-TP be used as a direct replacement for the HER608-TP in existing designs?

A: Yes. The HER608GP-TP is electrically and mechanically equivalent to the HER608-TP. All electrical parameters, including voltage rating, current capacity, forward voltage drop, and reverse recovery time, are identical. The R-6 axial through-hole package is the same, allowing direct board-level substitution without design modification.

Q: What is the difference between the HER608-TP and HER608GP-TP?

A: The parts are electrically and mechanically identical. The primary differences are product status and packaging format. The HER608-TP is obsolete and supplied in bulk packaging, while the HER608GP-TP is an active product supplied in Tape & Reel format. The HER608GP-TP provides continued manufacturing support and supply chain availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant and Moisture Sensitivity Level 1 (Unlimited). Both parts use the same ECCN and HTSUS classifications.

Q: Does the Tape & Reel packaging of the HER608GP-TP affect its electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is a procurement and assembly convenience format that does not alter component specifications or functionality.

Q: What are the key electrical parameters that define substitution eligibility for the HER608-TP?

A: Substitution eligibility is determined by matching the following parameters: 1000 V DC reverse voltage rating, 6 A average rectified current, 1.7 V maximum forward voltage at 6 A, 75 ns reverse recovery time, 10 µA reverse leakage current at 1000 V, and 65 pF capacitance at 4 V and 1 MHz. The part must also use Standard technology classification and Fast Recovery speed characteristics.

Q: Can the HER608GP-TP be used in high-frequency switching applications?

A: The HER608GP-TP is classified as a fast recovery diode with a reverse recovery time of 75 ns. It is suitable for applications requiring switching speeds consistent with this recovery time specification. Applications requiring faster switching performance require evaluation of alternative diode types with shorter reverse recovery times.

Q: Is the HER608GP-TP suitable for automotive or industrial temperature ranges?

A: The HER608GP-TP operates across a junction temperature range of -55°C to 150°C, which covers standard industrial and extended commercial temperature ranges. Suitability for specific automotive or industrial applications depends on the thermal management design and ambient temperature profile of the target application.
