HER605-TP Equivalent & Substitute Parts

Part Overview

The HER605-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. The device features fast recovery characteristics with a 50 ns reverse recovery time and is housed in an R-6 axial through-hole package. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER605-TP is determined by strict equivalence across 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
• Mounting Type: Through Hole
• Package / Case: R-6, Axial
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations: Reverse recovery time (trr) and capacitance values may vary within the fast recovery classification (≤ 500 ns) without affecting functional compatibility. The substitute parts FR604GP-TP and FR604T-G both maintain all critical electrical ratings and mechanical specifications while offering active product status and improved supply availability.

Engineering Selection Recommendations

FR604GP-TP (Micro Commercial Co)

This substitute maintains identical electrical specifications to the HER605-TP across all critical parameters. The part is manufactured by the same supplier and carries active product status with ROHS3 compliance. The reverse recovery time of 150 ns remains within the fast recovery classification and does not impact circuit performance. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes. Current inventory of 885 pieces supports production requirements.

FR604T-G (Comchip Technology)

This substitute provides equivalent electrical performance with identical voltage, current, and forward voltage ratings. The part maintains the same reverse recovery time classification and capacitance specification as the original HER605-TP. Active product status and ROHS3 compliance ensure long-term availability and regulatory conformance. Comchip Technology manufacturing provides an alternative supply source, reducing single-source dependency. Current inventory of 1148 pieces provides robust supply availability.

Both substitutes are electrically and mechanically compatible with the HER605-TP and support direct replacement in circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can FR604GP-TP and FR604T-G be used interchangeably with HER605-TP?

A: Yes. Both substitute parts maintain identical voltage ratings (400 V), current ratings (6 A), forward voltage characteristics (1.3 V @ 6 A), and operating temperature range (-55°C to 150°C). All three devices are housed in R-6 axial through-hole packages and are ROHS3 compliant.

Q: What is the difference between the 50 ns and 150 ns reverse recovery times?

A: Both values fall within the fast recovery classification (≤ 500 ns). The HER605-TP specifies 50 ns while the substitute parts specify 150 ns. This variation does not affect functional compatibility in standard rectifier applications, as both meet the fast recovery speed requirement.

Q: Why is the HER605-TP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by the original supplier. The substitute parts FR604GP-TP and FR604T-G are classified as active, ensuring continued availability and manufacturer support.

Q: Are there packaging differences between the substitute parts?

A: The HER605-TP is supplied in bulk packaging. Both FR604GP-TP and FR604T-G are supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. The R-6 axial package remains identical across all three parts.

Q: Do the substitute parts have different capacitance values?

A: FR604GP-TP specifies 150 pF @ 4V, 1MHz, while FR604T-G specifies 100 pF @ 4V, 1MHz. The HER605-TP specifies 100 pF. These variations are within acceptable tolerances for general-purpose rectifier applications and do not affect circuit compatibility.

Q: Which substitute part should be selected for new designs?

A: Both FR604GP-TP and FR604T-G are suitable for new designs. FR604GP-TP maintains the same manufacturer as the original part, while FR604T-G provides an alternative supply source from Comchip Technology. Selection may be based on supply chain preferences, inventory availability, or cost considerations.
