RF1005TF6S Equivalent & Substitute Parts

Part Overview

The RF1005TF6S is a general-purpose rectifier diode manufactured by Rohm Semiconductor, rated for 600 V DC reverse voltage and 10 A average rectified current in a Through Hole TO-220NFM package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where this diode remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RF1005TF6S are identified based on strict electrical and mechanical parameter matching within the diode rectifier category. The substitution logic is based on the following critical parameters:

Electrical Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V (exact match required)
• Current - Average Rectified (Io): 10 A (exact match required)
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Recovery Time (trr): within acceptable range for fast recovery diodes
• Current - Reverse Leakage @ Vr: 10 µA @ 600 V (exact match)

Mechanical Matching Criteria:

• Mounting Type: Through Hole (required for direct substitution)
• Package / Case: TO-220-2 Full Pack (mechanical compatibility)
• Supplier Device Package: TO-220NFM or equivalent isolated tab variants (ITO-220AC)

Parts meeting these criteria can be substituted in applications where the RF1005TF6S is currently deployed, provided the forward voltage drop and recovery time characteristics are acceptable for the specific circuit design.

Parameter Comparison

Engineering Selection Recommendations

RF1005TF6S (Rohm Semiconductor): The RF1005TF6S is ROHS3 compliant and carries "Not For New Designs" status, indicating end-of-life classification. This part remains suitable for replacement and repair of existing systems where it is currently installed. Inventory availability is confirmed at 10,185 pieces.

DURF1060 (Littelfuse Inc.): The DURF1060 is an active product with ROHS3 compliance and represents the primary substitute for RF1005TF6S applications. Key differences include:

• Forward voltage drop is higher (2.2 V vs. 1.7 V @ 10 A), which affects power dissipation and thermal performance
• Reverse recovery time is faster (32 ns vs. 40 ns), providing improved switching characteristics
• Operating temperature range is wider (-55°C ~ 150°C vs. 150°C max), offering extended low-temperature capability
• Isolated tab variant (ITO-220AC) provides additional electrical isolation options
• Inventory availability is higher at 15,412 pieces

Selection between these parts depends on circuit requirements regarding forward voltage drop tolerance and thermal management capability. The DURF1060 is recommended for new applications and ongoing production due to its active status and superior availability.

Frequently Asked Questions (FAQ)

Q: Can DURF1060 directly replace RF1005TF6S in existing circuits?

A: Direct mechanical and electrical substitution is possible based on matching voltage (600 V), current (10 A), and package specifications (TO-220-2 Full Pack, Through Hole). However, the higher forward voltage drop of DURF1060 (2.2 V vs. 1.7 V @ 10 A) results in increased power dissipation. Circuit thermal analysis is required to confirm adequate heat dissipation capability at the higher power level.

Q: What is the significance of the isolated tab variant (ITO-220AC) in DURF1060?

A: The ITO-220AC package provides electrical isolation between the tab and the semiconductor junction, reducing parasitic capacitance and improving high-frequency performance in certain applications. The standard TO-220NFM package of RF1005TF6S does not provide this isolation. Selection depends on specific circuit requirements for isolation and thermal coupling.

Q: Are both parts RoHS compliant?

A: Yes, both RF1005TF6S and DURF1060 are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: Why is RF1005TF6S marked "Not For New Designs"?

A: This classification indicates the part has reached end-of-life status at the manufacturer. While existing inventory remains available for replacement and repair applications, new product designs should utilize active alternatives such as DURF1060 to ensure long-term supply chain stability and manufacturer support.

Q: What is the impact of the faster reverse recovery time in DURF1060?

A: The DURF1060 reverse recovery time of 32 ns (compared to 40 ns in RF1005TF6S) indicates faster switching behavior. This reduces switching losses and improves efficiency in high-frequency rectification circuits. Both parts meet fast recovery classification (≤ 500 ns), so this difference is secondary to the primary voltage and current ratings.

Q: Are there any moisture sensitivity considerations?

A: RF1005TF6S carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. DURF1060 is listed as "Not Applicable" for MSL, confirming equivalent moisture tolerance. Both parts can be stored and handled under standard industrial conditions without special moisture control requirements.
