SF38-TP Equivalent & Substitute Parts

Part Overview

The SF38-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Active alternatives with identical or superior electrical characteristics are available to maintain circuit functionality and performance.

Substitute Part Grouping Explanation

Substitute parts for the SF38-TP are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Packaging Variant): SF38G-TP maintains identical electrical specifications and base product lineage while differing only in packaging format (Tape & Reel versus bulk). This part is active and fully interchangeable in circuit design.

Similar Substitute (Higher Current Rating): MUR460 A0G shares the same voltage rating (600 V), package type (DO-201AD axial), and mounting method (through-hole) but provides increased current capacity (4 A versus 3 A). This part is suitable for applications requiring higher current margins or where the 3 A rating is insufficient.

Substitution eligibility is determined by:

• Voltage - DC Reverse (Vr) rating equal to or exceeding 600 V
• Current - Average Rectified (Io) rating equal to or exceeding 3 A
• Package / Case compatibility: DO-201AD axial through-hole
• Mounting Type: Through Hole
• RoHS3 compliance status

Parameter Comparison

Engineering Selection Recommendations

SF38G-TP is the primary substitute for SF38-TP applications. Both parts share identical electrical specifications and base product designation. SF38G-TP is currently in active production status with higher inventory availability (968 Pcs versus 850 Pcs). The only functional difference is packaging format: SF38G-TP is supplied in Tape & Reel format, suitable for automated assembly processes, while SF38-TP was supplied in bulk format. Operating temperature range is expanded in SF38G-TP (-65°C to 150°C versus -55°C to 125°C), providing improved thermal margin. Both parts maintain ROHS3 compliance and identical RoHS status.

MUR460 A0G is a compatible substitute for applications where increased current capacity is required or beneficial. This part provides 4 A average rectified current versus the 3 A specification of SF38-TP, maintaining the same 600 V voltage rating and DO-201AD package. MUR460 A0G exhibits lower forward voltage drop (1.28 V @ 4 A) and extended operating temperature range (-55°C to 175°C). Reverse recovery time is slightly longer (50 ns versus 35 ns), and reverse leakage current is higher (10 µA versus 5 µA). MUR460 A0G is supplied in Cut Tape format and maintains ROHS3 compliance with REACH Unaffected status.

Selection between SF38G-TP and MUR460 A0G depends on circuit current requirements and thermal operating conditions. For direct replacement of SF38-TP designs, SF38G-TP is the appropriate choice. For applications requiring higher current capacity or extended temperature operation, MUR460 A0G is suitable.

Frequently Asked Questions (FAQ)

Q: Can SF38G-TP be used as a direct replacement for SF38-TP?

A: Yes. SF38G-TP is electrically and mechanically identical to SF38-TP. Both parts share the same base product number (SF38), voltage rating (600 V), current rating (3 A), package type (DO-201AD axial), and mounting method (through-hole). The only difference is packaging format: SF38G-TP is supplied in Tape & Reel format for automated assembly, while SF38-TP was supplied in bulk format. Circuit performance is identical.

Q: What are the key differences between SF38G-TP and MUR460 A0G?

A: Both parts share 600 V voltage rating and DO-201AD axial through-hole package. MUR460 A0G provides higher current capacity (4 A versus 3 A), lower forward voltage drop (1.28 V @ 4 A versus 1.75 V @ 3 A), and extended operating temperature range (-55°C to 175°C versus -65°C to 150°C). MUR460 A0G has slightly longer reverse recovery time (50 ns versus 35 ns) and higher reverse leakage current (10 µA versus 5 µA). MUR460 A0G is manufactured by Taiwan Semiconductor Corporation, while SF38G-TP is manufactured by Micro Commercial Co.

Q: Is MUR460 A0G suitable for all SF38-TP applications?

A: MUR460 A0G is suitable for applications where the circuit current requirement does not exceed 4 A and the operating temperature range does not exceed -55°C to 175°C. The higher current rating and lower forward voltage drop of MUR460 A0G provide design margin in most applications. However, the slightly longer reverse recovery time and higher reverse leakage current must be evaluated for high-frequency switching or precision analog applications.

Q: What packaging formats are available for these substitute parts?

A: SF38-TP was supplied in bulk format. SF38G-TP is supplied in Tape & Reel (TR) format for automated assembly. MUR460 A0G is supplied in Cut Tape (CT) format. All three parts use the same DO-201AD axial through-hole package and are compatible with manual or automated insertion equipment.

Q: Are all substitute parts RoHS compliant?

A: Yes. SF38-TP, SF38G-TP, and MUR460 A0G are all ROHS3 compliant. SF38G-TP and MUR460 A0G both carry REACH Unaffected status, confirming compliance with environmental regulations.

Q: What is the inventory status of these parts?

A: SF38-TP has 850 Pcs in stock (obsolete status). SF38G-TP has 968 Pcs in stock (active status). MUR460 A0G has 1367 Pcs in stock (active status). For new designs, SF38G-TP or MUR460 A0G are recommended due to active production status and higher availability.
