FR602-AP Equivalent & Substitute Parts

Part Overview

The FR602-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 6 A average rectified current in an R-6 axial through-hole package. This part 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.

Substitute Part Grouping Explanation

Substitution of the FR602-AP is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 100 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 @ 100 V
Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

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

Substitute parts are grouped into two categories: direct manufacturer equivalents (same manufacturer, active product status) and parametric equivalents (alternative manufacturers, identical electrical specifications). All identified substitutes maintain full electrical and thermal performance parity with the FR602-AP across the specified operating range.

Engineering Selection Recommendations

FR602GP-AP (Micro Commercial Co) is the primary substitute for FR602-AP. This part is manufactured by the same original equipment manufacturer and maintains identical electrical specifications, thermal performance, and package configuration. The FR602GP-AP carries active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating equivalent environmental and moisture handling requirements.

FR602B-G (Comchip Technology) is a parametric equivalent substitute. This part meets all critical electrical specifications including voltage rating, current capacity, forward voltage drop, reverse recovery time, and leakage current. Operating temperature range is identical. The FR602B-G is supplied in Tape & Box packaging and carries active product status. Capacitance specification differs slightly (100 pF versus 150 pF at 4V, 1MHz), remaining within acceptable tolerance for general-purpose rectification applications. ROHS3 compliance and MSL rating of 1 (Unlimited) match the original part.

Selection between FR602GP-AP and FR602B-G depends on packaging requirements and supply chain preferences. FR602GP-AP provides direct manufacturer continuity. FR602B-G provides alternative sourcing with identical electrical performance and lower capacitance specification.

Frequently Asked Questions (FAQ)

Q: Can FR602GP-AP be used as a direct replacement for FR602-AP?

A: Yes. FR602GP-AP is manufactured by Micro Commercial Co and maintains identical electrical specifications, thermal ratings, and R-6 axial through-hole package configuration. The primary difference is product status: FR602GP-AP is active while FR602-AP is obsolete.

Q: What is the difference between FR602GP-AP and FR602B-G?

A: Both parts meet identical voltage (100 V), current (6 A), forward voltage (1.3 V @ 6 A), and thermal specifications (-55°C to 150°C). FR602GP-AP is manufactured by Micro Commercial Co; FR602B-G is manufactured by Comchip Technology. FR602B-G has lower capacitance (100 pF versus 150 pF at 4V, 1MHz). FR602GP-AP is supplied in standard packaging; FR602B-G is supplied in Tape & Box packaging.

Q: Are all three parts RoHS compliant?

A: Yes. FR602-AP, FR602GP-AP, and FR602B-G are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does the capacitance difference between FR602GP-AP and FR602B-G affect circuit performance?

A: The capacitance specification (150 pF versus 100 pF at 4V, 1MHz) reflects junction capacitance characteristics. Both values are within the range for general-purpose rectifier diodes. Selection depends on specific circuit requirements for high-frequency applications or switching transient behavior.
