Substitute Part Grouping Explanation

Substitute parts for the FR604-TP are identified based on electrical and mechanical parameter equivalence. The substitution criteria are:

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
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Package / Case: R-6, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C ~ 150°C

Allowable Parameter Variations:

• Capacitance @ Vr, F: Minor variations permitted (100 pF to 150 pF range)
• Packaging Format: Bulk or Tape & Reel (TR) acceptable for through-hole components
• Manufacturer: Different manufacturers permitted if electrical specifications match

The identified substitutes maintain full electrical and mechanical compatibility with the FR604-TP while offering active product status and current availability.

Engineering Selection Recommendations

FR604GP-TP (Direct Manufacturer Substitute)

The FR604GP-TP is manufactured by Micro Commercial Co, the original manufacturer of the FR604-TP. This substitute maintains identical electrical specifications and is classified as an active product with current inventory availability (885 Pcs). The primary difference is packaging format: FR604GP-TP is supplied in Tape & Reel (TR) format versus bulk packaging for the original part. Both parts carry ROHS3 compliance and identical ECCN/HTSUS classifications. This substitute is suitable for direct replacement in applications where tape and reel packaging is compatible with assembly processes.

FR604T-G (Parametric Equivalent from Alternative Manufacturer)

The FR604T-G is manufactured by Comchip Technology and provides parametric equivalence across all critical electrical specifications. This substitute maintains the 400 V reverse voltage rating, 6 A current rating, 1.3 V forward voltage, and 150 ns reverse recovery time. The capacitance specification differs slightly (100 pF versus 150 pF), which remains within acceptable tolerance for general-purpose rectifier applications. FR604T-G is classified as active with higher inventory availability (1148 Pcs). This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and provides supply chain diversification.

Both substitutes are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and maintain identical export classification codes.

Frequently Asked Questions (FAQ)

Q: Can FR604GP-TP be used as a direct replacement for FR604-TP?

A: Yes. FR604GP-TP is electrically and mechanically identical to FR604-TP. The only difference is packaging format: FR604GP-TP is supplied in Tape & Reel (TR) format. Both parts have identical voltage ratings (400 V), current ratings (6 A), forward voltage (1.3 V @ 6 A), and reverse recovery time (150 ns). Compatibility depends on whether your assembly process accommodates tape and reel packaging.

Q: What is the difference between FR604T-G and FR604-TP?

A: FR604T-G is manufactured by Comchip Technology rather than Micro Commercial Co, but maintains all critical electrical specifications: 400 V reverse voltage, 6 A current, 1.3 V forward voltage, and 150 ns reverse recovery time. The capacitance specification is 100 pF (versus 150 pF in FR604-TP), which is a minor variation acceptable for general-purpose rectifier applications. FR604T-G is supplied in Tape & Reel format.

Q: Are all three parts RoHS compliant?

A: Yes. FR604-TP, FR604GP-TP, and FR604T-G are all ROHS3 compliant. All three parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: FR604-TP is supplied in bulk packaging, while FR604GP-TP and FR604T-G are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides better component protection during handling and storage. Bulk packaging is typically used for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Can I use FR604T-G if I need exactly 150 pF capacitance?

A: FR604T-G has a capacitance specification of 100 pF @ 4V, 1MHz, compared to 150 pF for FR604-TP and FR604GP-TP. For general-purpose rectifier applications, this variation is within acceptable tolerance. If your circuit design requires the specific 150 pF value, FR604GP-TP is the appropriate choice.

Q: Which substitute has better availability?

A: FR604T-G has the highest current inventory (1148 Pcs), followed by FR604GP-TP (885 Pcs). Both are classified as active products with ongoing manufacturing support.

Q: Are the operating temperature ranges identical?

A: Yes. All three parts operate across the same junction temperature range: -55°C to 150°C.
