FR606-AP Equivalent & Substitute Parts

Part Overview

The FR606-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 6 A average rectified current in an R-6 axial through-hole package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR606-AP is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 6 A
• Reverse Recovery Time (trr): 500 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

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

Compliance Equivalence Criteria:

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

Substitute parts are classified into two categories: direct manufacturer equivalents (same manufacturer, active product status) and parametric equivalents (alternative manufacturers, identical electrical specifications).

Engineering Selection Recommendations

FR606GP-AP (Direct Manufacturer Equivalent - Recommended Primary Choice)

The FR606GP-AP is the direct successor to the FR606-AP from Micro Commercial Co. This part maintains identical electrical specifications across all critical parameters: 800 V reverse voltage, 6 A average rectified current, 1.3 V forward voltage drop, 500 ns reverse recovery time, and 10 µA reverse leakage current. The FR606GP-AP carries active product status, ensuring long-term availability and supply chain continuity. Compliance certifications are equivalent, with ROHS3 compliance and MSL 1 rating. This part is the optimal selection for direct replacement in existing designs.

FR606B-G (Parametric Equivalent - Alternative Selection)

The FR606B-G from Comchip Technology provides full electrical equivalence across voltage, current, and thermal specifications. All critical rectifier parameters match the FR606-AP: 800 V reverse voltage, 6 A average rectified current, 1.3 V forward voltage, 500 ns reverse recovery time, and 10 µA reverse leakage. The FR606B-G is supplied in Tape & Box packaging, which differs from the standard packaging of the main part but is compatible with automated assembly processes. Capacitance specification is 100 pF at 4V, 1MHz, which is lower than the 150 pF specification of the FR606-AP. This minor difference does not affect rectifier functionality in standard applications. The FR606B-G carries active product status and equivalent compliance certifications. This part is suitable for applications where alternative manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can FR606GP-AP be used as a direct replacement for FR606-AP?

A: Yes. The FR606GP-AP is electrically and mechanically identical to the FR606-AP across all specified parameters. Both parts are manufactured by Micro Commercial Co, rated for 800 V and 6 A, and packaged in R-6 axial through-hole format. The FR606GP-AP is the active production equivalent.

Q: What is the difference between FR606GP-AP and FR606B-G?

A: Both parts are electrically equivalent in rectifier function. The primary differences are manufacturer (Micro Commercial Co versus Comchip Technology) and packaging format (standard versus Tape & Box). The FR606B-G has a capacitance specification of 100 pF compared to 150 pF for the FR606-AP, but this does not affect rectifier performance in standard applications.

Q: Is the Tape & Box packaging of FR606B-G compatible with my assembly process?

A: Tape & Box packaging is standard for automated pick-and-place assembly. If your process requires bulk or alternative packaging formats, contact the supplier for packaging options. The electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both FR606GP-AP and FR606B-G carry ROHS3 compliance certification, matching the compliance status of the FR606-AP.

Q: Can I use these parts interchangeably in my circuit?

A: Yes, within the scope of standard rectifier applications. All substitute parts maintain the same voltage rating (800 V), current rating (6 A), forward voltage drop (1.3 V @ 6 A), and thermal operating range (-55°C to 150°C). The R-6 axial through-hole package is identical across all parts.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the main FR606-AP and substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
