RF601T2D Equivalent & Substitute Parts

Part Overview

The RF601T2D is a general-purpose diode array manufactured by Rohm Semiconductor, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 200 V and average rectified current of 3 A per diode. The component is housed in a TO-220-3 Full Pack through-hole package and is classified as Active product status with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges, or when higher current ratings provide functional compatibility for applications with design margin requirements. Alternative sources and configurations are documented to support component availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RF601T2D are classified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 200 V (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package / Case: TO-220-3 or TO-220-3 Full Pack (mandatory match)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io): Equal or greater rating
• Voltage - Forward (Vf): Within acceptable operating range
• Reverse Recovery Time (trr): Equal or lower value
• Current - Reverse Leakage @ Vr: Equal or lower value
• Operating Temperature - Junction: Equal or higher maximum rating
• RoHS Status: ROHS3 Compliant (mandatory match)

Substitutes are organized into three categories: Rohm Semiconductor variants with identical base product number (RF601 series), direct cross-reference from alternative manufacturer (onsemi MUR620CTG), and higher-current-rated alternatives (onsemi FFPF20UP20DNTU).

Parameter Comparison

Engineering Selection Recommendations

RF601T2DNZC9 (Rohm Semiconductor)

This part is a direct Rohm Semiconductor variant within the RF601 base product family. It maintains identical electrical characteristics to the RF601T2D with the exception of current rating, which is doubled to 6 A per diode. The part is Active status with ROHS3 compliance. Selection of this substitute is appropriate when higher current capacity is required within the same voltage and package specifications. Packaging is supplied in Tube format.

MUR620CTG (onsemi)

This part is manufactured by onsemi under the SWITCHMODE™ series designation. It provides electrical equivalence at the 3 A current rating with identical 200 V reverse voltage and TO-220-3 package configuration. The reverse recovery time is 35 ns compared to 25 ns for the RF601T2D, and reverse leakage current is lower at 5 µA. Operating temperature range extends to 175°C maximum junction temperature. The part is Active status with ROHS3 compliance. This substitute is suitable for direct replacement in applications where onsemi component qualification is acceptable.

FFPF20UP20DNTU (onsemi)

This part is an onsemi avalanche-rated diode array with 10 A current capacity per diode. It maintains the 200 V reverse voltage and TO-220-3 Full Pack configuration. The part is classified as Obsolete product status. Selection of this substitute is limited to applications requiring higher current capacity and where component obsolescence does not present supply chain risk. The reverse recovery time is 45 ns and reverse leakage current is elevated at 100 µA compared to the RF601T2D.

Frequently Asked Questions (FAQ)

Q: Can RF601T2DNZC9 be used as a direct replacement for RF601T2D?

A: RF601T2DNZC9 is electrically compatible with RF601T2D in all critical parameters including voltage rating, package type, and speed classification. The primary difference is the doubled current rating of 6 A versus 3 A. This part can be used in applications designed for RF601T2D operation. The higher current rating provides additional design margin without affecting circuit function at the original 3 A specification.

Q: What is the difference between MUR620CTG and RF601T2D?

A: MUR620CTG is manufactured by onsemi and provides equivalent electrical performance at the 3 A current rating and 200 V voltage specification. Key differences include: reverse recovery time of 35 ns versus 25 ns, lower reverse leakage current of 5 µA versus 10 µA, and extended operating temperature range to 175°C. Both parts use identical TO-220-3 package configuration and are ROHS3 compliant.

Q: Is FFPF20UP20DNTU suitable for RF601T2D applications?

A: FFPF20UP20DNTU maintains the 200 V voltage rating and TO-220-3 Full Pack package configuration required for RF601T2D compatibility. However, this part is classified as Obsolete product status. The 10 A current rating exceeds RF601T2D specification, and the reverse leakage current of 100 µA is significantly higher. Use of this substitute is limited to applications where higher current capacity is required and component obsolescence does not present supply chain constraints.

Q: What packaging formats are available for these substitutes?

A: RF601T2D is supplied in standard packaging format. RF601T2DNZC9 is supplied in Tube packaging. MUR620CTG is supplied in Tube packaging. FFPF20UP20DNTU is supplied in Tube packaging. All parts use identical TO-220-3 or TO-220-3 Full Pack through-hole package cases suitable for PCB mounting.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed (RF601T2DNZC9, MUR620CTG, and FFPF20UP20DNTU) are ROHS3 compliant. This compliance status matches the RF601T2D specification and supports regulatory requirements for electronic component procurement.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) indicates the speed at which the diode transitions from forward conduction to reverse blocking state. RF601T2D specifies 25 ns, MUR620CTG specifies 35 ns, and FFPF20UP20DNTU specifies 45 ns. Lower values indicate faster switching performance. In fast-switching applications, the RF601T2D and RF601T2DNZC9 with 25 ns recovery time provide superior performance. MUR620CTG and FFPF20UP20DNTU with longer recovery times remain within the Fast Recovery classification but exhibit slightly slower switching characteristics.

Q: Can these parts be used interchangeably in existing designs?

A: RF601T2DNZC9 and MUR620CTG can be used as direct substitutes in designs specified for RF601T2D operation, provided that the higher current rating of RF601T2DNZC9 (6 A) does not create thermal or electrical conflicts. FFPF20UP20DNTU is not recommended for direct substitution due to Obsolete product status and significantly higher reverse leakage current, unless the application specifically requires the 10 A current capacity.
