FR307-AP Equivalent & Substitute Parts

Part Overview

The FR307-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. The FR307-AP operates across a junction temperature range of -55°C to 150°C and complies with RoHS3 standards. Due to its obsolete status, sourcing active alternatives with identical electrical and mechanical specifications is necessary for design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR307-AP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal 1000 V
• Current - Average Rectified (Io): Must equal 3 A
• Voltage - Forward (Vf) (Max) @ If: Must equal 1.3 V @ 3 A
• Reverse Recovery Time (trr): Must equal 500 ns (fast recovery classification)

Mechanical Equivalence Criteria:

• Package / Case: Must be DO-201AD, Axial
• Mounting Type: Must be Through Hole

Compliance Criteria:

• RoHS Status: Must maintain ROHS3 Compliant status
• Operating Temperature Range: Must support -55°C ~ 150°C

The FR307GP-AP qualifies as a direct substitute because it meets all electrical and mechanical parameters identically. Additionally, FR307GP-AP holds active product status, ensuring ongoing availability and supply chain support. Secondary cross-reference RGP25M-E3/54 is listed within the FR307GP-AP documentation but requires independent verification of all parameters against the above criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: FR307GP-AP

The FR307GP-AP is the direct functional equivalent of the FR307-AP. Both parts share identical electrical ratings (1000 V reverse voltage, 3 A average rectified current, 1.3 V forward voltage at 3 A, 500 ns reverse recovery time) and mechanical specifications (DO-201AD axial through-hole package). The FR307GP-AP maintains ROHS3 compliance and operates across the same temperature range (-55°C to 150°C).

The critical distinction is product status: FR307GP-AP is classified as active, ensuring continued manufacturing and supply availability. The FR307-AP is obsolete, making FR307GP-AP the appropriate selection for new designs, production restocking, and field replacements where long-term component availability is required.

Both parts are manufactured by Micro Commercial Co and carry identical base product number FR307, confirming their design equivalence. Selection of FR307GP-AP eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can FR307GP-AP be used as a direct replacement for FR307-AP in existing circuits?

A: Yes. The FR307GP-AP meets all electrical and mechanical specifications of the FR307-AP. Both parts have identical voltage ratings (1000 V), current ratings (3 A), forward voltage characteristics (1.3 V @ 3 A), recovery time (500 ns), and package configuration (DO-201AD axial through-hole). No circuit modifications are required.

Q: What is the primary advantage of FR307GP-AP over FR307-AP?

A: FR307GP-AP holds active product status, ensuring ongoing manufacturing and supply chain availability. The FR307-AP is obsolete and subject to limited stock and discontinuation. For production applications, FR307GP-AP provides supply continuity and long-term sourcing reliability.

Q: Are there differences in reverse leakage current between FR307-AP and FR307GP-AP?

A: Yes. FR307-AP specifies 10 µA reverse leakage at 1000 V, while FR307GP-AP specifies 5 µA at 1000 V. FR307GP-AP exhibits lower reverse leakage, which represents an improvement in performance characteristics. This difference does not prevent substitution; it indicates enhanced device quality in the active equivalent.

Q: Are there differences in capacitance between FR307-AP and FR307GP-AP?

A: Yes. FR307-AP specifies 65 pF at 4 V, 1 MHz, while FR307GP-AP specifies 50 pF at 4 V, 1 MHz. The lower capacitance of FR307GP-AP may provide marginal benefits in high-frequency switching applications but does not affect compatibility in standard rectification circuits.

Q: Is the DO-201AD package identical for both parts?

A: Yes. Both FR307-AP and FR307GP-AP use the DO-201AD axial through-hole package. Pin spacing, lead diameter, and mounting footprint are identical. No PCB layout modifications are necessary when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both FR307-AP and FR307GP-AP are ROHS3 compliant. FR307GP-AP additionally carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the operating temperature range for both parts?

A: Both FR307-AP and FR307GP-AP operate across a junction temperature range of -55°C to 150°C. This range is identical and supports applications across industrial, commercial, and consumer temperature environments.
