FR605-TP Equivalent & Substitute Parts

Part Overview

The FR605-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 6 A average rectified current. The device features fast recovery characteristics with a reverse recovery time of 250 ns and is housed in an R-6 axial through-hole package. The FR605-TP is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and design applications. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR605-TP are classified based on strict electrical and mechanical parameter equivalence. All substitute candidates must satisfy the following criteria:

Mandatory Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 6 A
• Reverse Recovery Time (trr): 250 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 600 V
• Operating Temperature - Junction: -55°C to 150°C

Mandatory Mechanical Parameters:

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

Acceptable Variations:

• Capacitance @ Vr, F: Variations within the range of 100 pF to 150 pF at 4 V, 1 MHz are acceptable
• Packaging format (bulk vs. Tape & Reel) does not affect electrical equivalence
• Product status transition from obsolete to active is permissible for substitution purposes

Engineering Selection Recommendations

FR605GP-TP (Direct Manufacturer Substitute)

The FR605GP-TP is manufactured by Micro Commercial Co and maintains identical electrical specifications to the FR605-TP across all critical parameters. This part is classified as active, ensuring long-term availability and supply chain continuity. The primary distinction is packaging format: FR605GP-TP is supplied in Tape & Reel (TR) configuration versus the bulk packaging of the main part. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited). Selection of FR605GP-TP is appropriate for applications requiring direct manufacturer continuity and identical performance characteristics.

FR605T-G (Parametric Equivalent from Alternative Manufacturer)

The FR605T-G is manufactured by Comchip Technology and satisfies all mandatory electrical parameters with one minor variation: capacitance is specified at 100 pF versus 150 pF at 4 V, 1 MHz. This reduction in capacitance does not affect the core rectification function and remains within acceptable tolerance for general-purpose rectifier applications. The FR605T-G is active and available in Tape & Reel packaging. This part is suitable for applications where manufacturer diversification is acceptable and the lower capacitance specification is compatible with circuit design requirements. ROHS3 compliance and MSL rating of 1 (Unlimited) are maintained.

Both substitute parts are suitable for direct replacement in applications currently utilizing the FR605-TP, provided that packaging format and supply chain preferences are accommodated.

Frequently Asked Questions (FAQ)

Q: Can FR605GP-TP be used as a direct replacement for FR605-TP?

A: Yes. The FR605GP-TP maintains identical electrical specifications across voltage rating, current capacity, forward voltage drop, reverse recovery time, reverse leakage current, and operating temperature range. Both parts use the R-6 axial through-hole package. The primary difference is packaging format: FR605GP-TP is supplied in Tape & Reel configuration. Electrical performance and PCB mounting compatibility are equivalent.

Q: What is the significance of the capacitance difference between FR605GP-TP and FR605T-G?

A: The FR605GP-TP specifies 150 pF capacitance at 4 V, 1 MHz, while the FR605T-G specifies 100 pF under identical conditions. Both values are within acceptable ranges for general-purpose rectifier diodes. The lower capacitance of the FR605T-G may result in slightly faster switching characteristics in high-frequency applications, but this difference does not affect standard rectification performance. Selection between these parts should be based on circuit-specific requirements and manufacturer availability.

Q: Why is the FR605-TP classified as obsolete?

A: The FR605-TP is listed as obsolete by the manufacturer. Active substitute parts FR605GP-TP and FR605T-G are available to support ongoing procurement requirements. Both substitutes maintain full electrical and mechanical compatibility with the original part.

Q: Are there packaging considerations when substituting FR605-TP with FR605GP-TP or FR605T-G?

A: All three parts use identical R-6 axial through-hole packages and are mounted using the same PCB footprint. FR605GP-TP and FR605T-G are supplied in Tape & Reel format, which is standard for high-volume production. If bulk packaging is required, availability should be confirmed with the supplier. Mechanical compatibility and PCB assembly processes remain unchanged.

Q: Do all substitute parts meet RoHS and environmental compliance requirements?

A: Yes. Both FR605GP-TP and FR605T-G are ROHS3 compliant and carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), matching the compliance profile of the original FR605-TP. Both parts are suitable for applications with RoHS requirements.

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

A: Selection depends on design and supply chain priorities. FR605GP-TP is recommended for designs requiring manufacturer continuity with Micro Commercial Co. FR605T-G is recommended for designs where manufacturer diversification is acceptable and lower capacitance specification is compatible with circuit requirements. Both parts are active and available for long-term procurement.
