FR601GP-TP Equivalent & Substitute Parts

Part Overview

The FR601GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50V DC reverse voltage and 6A average rectified current in an R-6 axial through-hole package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Identifying equivalent substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part number may be unavailable or discontinued.

Substitute Part Grouping Explanation

Substitution of the FR601GP-TP is determined by strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 50V maximum
• Current Rating: Average rectified current must equal 6A
• Forward Voltage Drop: Maximum forward voltage at rated current must equal 1.3V @ 6A
• Recovery Characteristics: Reverse recovery time must equal 150ns with fast recovery classification (≤500ns, >200mA)
• Reverse Leakage: Maximum reverse leakage current must equal 10µA @ 50V
• Package Configuration: R-6 axial through-hole package required for mechanical and electrical compatibility
• Operating Temperature Range: Junction temperature range must span -55°C to 150°C minimum
• Compliance: RoHS3 compliance required

The FR601T-G manufactured by Comchip Technology meets all these criteria and is classified as an active product, making it a direct parametric equivalent for the discontinued FR601GP-TP.

Parameter Comparison

*Capacitance variance (150pF vs 100pF) falls within acceptable tolerance for general-purpose rectifier applications and does not affect substitution eligibility.

Engineering Selection Recommendations

The FR601T-G is a direct parametric substitute for the FR601GP-TP based on electrical and mechanical equivalence. Selection between these parts should be based on the following factors:

Product Status: The FR601GP-TP is designated "Not For New Designs," indicating end-of-life status. The FR601T-G carries "Active" product status, ensuring ongoing availability and manufacturer support.

Compliance Certifications: Both parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, ensuring regulatory equivalence for procurement and export purposes.

Inventory Availability: Current stock levels differ between suppliers. Selection may depend on supply chain requirements and lead time constraints.

Electrical Performance: All critical electrical parameters are identical, including voltage rating, current capacity, forward voltage drop, and reverse recovery characteristics. The minor difference in junction capacitance (150pF vs 100pF) does not impact functional equivalence in standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the FR601T-G be used as a direct replacement for the FR601GP-TP in existing designs?

A: Yes. The FR601T-G meets all electrical and mechanical specifications of the FR601GP-TP. Both parts share identical voltage ratings (50V), current ratings (6A), forward voltage characteristics (1.3V @ 6A), recovery time (150ns), and R-6 axial through-hole package configuration. No circuit modifications are required.

Q: What is the significance of the "Not For New Designs" status on the FR601GP-TP?

A: This designation indicates the part has been discontinued by the manufacturer for new product development. It does not affect the part's functionality in existing applications. The FR601T-G, with "Active" status, is the recommended alternative for ongoing procurement.

Q: Are there differences in the capacitance specifications between these parts?

A: The FR601GP-TP specifies 150pF @ 4V, 1MHz, while the FR601T-G specifies 100pF @ 4V, 1MHz. This 50pF difference is within acceptable tolerance for general-purpose rectifier diodes and does not affect substitution eligibility or circuit performance in standard applications.

Q: Do both parts require the same PCB footprint?

A: Yes. Both the FR601GP-TP and FR601T-G use the R-6 axial through-hole package, requiring identical lead spacing and mounting hole dimensions. No PCB redesign is necessary.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, carry the same ECCN classification (EAR99), and share identical HTSUS codes (8541.10.0080). They are equivalent for regulatory and procurement purposes.

Q: What is the reverse recovery time, and why is it important?

A: Both parts specify a reverse recovery time (trr) of 150ns, classifying them as fast recovery diodes. This parameter determines switching speed and is critical in high-frequency rectification circuits. The identical specification ensures equivalent performance in time-sensitive applications.

Q: Can I mix FR601GP-TP and FR601T-G parts in the same production batch?

A: Yes. Since both parts are parametrically equivalent and share identical electrical and mechanical specifications, they can be used interchangeably within the same circuit or assembly without functional impact.
