Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR1004-TP is determined by electrical and mechanical compatibility across the following critical parameters:

Direct Equivalent Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 10 A
• Package / Case: R-6, Axial
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 150°C

Similar Substitute Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Package / Case: R-6, Axial
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 150°C
• Current - Average Rectified (Io): Lower rated current (6 A vs. 10 A)

The FR1004GP-TP qualifies as a direct equivalent, maintaining identical electrical ratings and package specifications while offering active product status. The HER605G A0G functions as a similar substitute with reduced current capacity, suitable for applications requiring lower current handling.

Engineering Selection Recommendations

FR1004GP-TP (Direct Equivalent - Recommended Primary Choice)

The FR1004GP-TP is the direct functional equivalent of the FR1004-TP, maintaining identical electrical specifications including 400 V reverse voltage rating, 10 A average rectified current, and 150 ns reverse recovery time. This part carries active product status, ensuring long-term availability and supply chain continuity. The FR1004GP-TP is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary distinction is packaging format: FR1004GP-TP is supplied in Tape & Reel (TR) configuration versus bulk packaging for the original part. Reverse leakage current is improved at 5 µA compared to 10 µA, representing enhanced performance characteristics. This part is suitable for direct substitution in all applications previously using the FR1004-TP.

HER605G A0G (Similar Substitute - Current-Limited Applications)

The HER605G A0G functions as a similar substitute for applications where the 10 A current rating of the FR1004-TP exceeds design requirements. This part maintains the 400 V reverse voltage rating, R-6 axial package, and through-hole mounting configuration. The HER605G A0G is rated for 6 A average rectified current, representing a 40% reduction in current capacity. Reverse recovery time is improved at 50 ns versus 150 ns, providing faster switching characteristics. This part is ROHS3 compliant and REACH unaffected. The HER605G A0G is suitable only for circuits designed to operate within 6 A maximum current specifications and should not be used as a direct replacement in applications requiring the full 10 A capacity of the FR1004-TP.

Frequently Asked Questions (FAQ)

Q: Can FR1004GP-TP be used as a direct replacement for FR1004-TP?

A: Yes. The FR1004GP-TP is a direct equivalent with identical electrical ratings (400 V, 10 A, 150 ns reverse recovery time) and package specifications (R-6 axial, through-hole). The primary difference is packaging format (Tape & Reel versus bulk) and improved reverse leakage current (5 µA versus 10 µA). Both parts are ROHS3 compliant.

Q: What is the key limitation of HER605G A0G as a substitute?

A: The HER605G A0G is rated for 6 A average rectified current, compared to 10 A for the FR1004-TP. This part is suitable only for applications where circuit current requirements do not exceed 6 A. Use of this part in circuits designed for 10 A operation will result in component overstress and potential failure.

Q: Are all substitute parts compatible with the R-6 axial through-hole package footprint?

A: Yes. Both FR1004GP-TP and HER605G A0G utilize the R-6 axial package with through-hole mounting, maintaining mechanical and electrical compatibility with existing PCB designs and assembly processes.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Yes. Both FR1004GP-TP and HER605G A0G are ROHS3 compliant. The FR1004GP-TP is additionally REACH unaffected, as is the HER605G A0G.

Q: What is the difference in reverse recovery time between the main part and HER605G A0G?

A: The FR1004-TP has a reverse recovery time of 150 ns, while the HER605G A0G has 50 ns. The faster recovery time of the HER605G A0G may provide improved switching performance in high-frequency applications, provided the 6 A current rating is sufficient for the circuit design.

Q: Is packaging format (Tape & Reel versus bulk) a functional consideration?

A: No. Packaging format affects procurement, handling, and assembly processes but does not alter electrical or mechanical functionality. Both formats contain identical components. Selection between Tape & Reel and bulk packaging depends on manufacturing volume and assembly equipment compatibility.
