MBR160 Equivalent & Substitute Parts

Part Overview

The MBR160 is a Schottky rectifier diode rated for 60 V DC reverse voltage and 1 A average rectified current in an axial through-hole package (DO-204AL, DO-41). This component is classified as obsolete, though 2,782 pieces remain in stock as new original inventory. The MBR160 is manufactured by onsemi and features fast recovery characteristics with a maximum forward voltage of 750 mV at 1 A and reverse leakage current of 500 µA at 60 V.

Due to the obsolete product status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Suitable alternatives maintain identical or superior electrical performance while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the MBR160 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 1 A
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 500 µA @ 60 V
Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, or Axial variants

Acceptable Variations:

Forward voltage (Vf) may be equal to or lower than the original specification
Operating temperature range may be equal to or wider than the original specification
RoHS compliance status may differ (original is non-compliant; substitutes may be compliant)
Packaging format (Bulk, Cut Tape, Tape & Reel) does not affect electrical equivalence

Substitute parts are grouped into two categories: direct equivalents (identical base part number with different packaging or compliance variants) and similar alternatives (different manufacturers with identical electrical specifications).

Engineering Selection Recommendations

Primary Recommendation: MBR160G

The MBR160G is the direct equivalent of the MBR160, manufactured by onsemi with identical electrical specifications and package dimensions. This part is active in production with 7,897 pieces in stock and carries ROHS3 compliance certification. The MBR160G is the preferred choice for direct replacement in existing designs.

Secondary Recommendations for Active Designs:

SB160-E3/54 (Vishay General Semiconductor - Diodes Division) offers superior forward voltage performance at 650 mV @ 1 A compared to the original 750 mV specification, with identical reverse voltage and current ratings. This part is ROHS3 compliant and maintains the full operating temperature range of -65°C to 150°C. Inventory availability is 12,440 pieces.

SB160-T (Diodes Incorporated) provides electrical equivalence with 700 mV forward voltage and ROHS3 compliance. Operating temperature range is -65°C to 150°C. Inventory availability is 5,400 pieces.

SB160E-G (Comchip Technology) delivers identical electrical specifications with 700 mV forward voltage and ROHS3 compliance. Operating temperature range is -65°C to 150°C. Inventory availability is 10,464 pieces.

SR106-TP (Micro Commercial Co) is available in Tape & Reel packaging with ROHS3 compliance and 700 mV forward voltage. Operating temperature range is -55°C to 125°C. Inventory availability is 1,049 pieces.

SR106 R1G (Taiwan Semiconductor Corporation) offers ROHS3 compliance with 700 mV forward voltage and operating temperature range of -55°C to 150°C. Inventory availability is 779 pieces.

Note on SR206-AP: This part is not recommended as a substitute. Although it shares the same 60 V reverse voltage rating and through-hole package, the SR206-AP is rated for 2 A average rectified current, which exceeds the MBR160 specification of 1 A. This higher current rating results in different reverse leakage characteristics (1 mA @ 60 V versus 500 µA @ 60 V) and different forward voltage specifications (700 mV @ 2 A), making it electrically incompatible for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the MBR160G be used as a direct replacement for the MBR160?

A: Yes. The MBR160G is manufactured by onsemi with identical electrical specifications, package dimensions, and mounting type. The primary differences are active product status and ROHS3 compliance certification. No circuit modifications are required.

Q: What is the difference between the various SB160 variants (SB160, SB160-E3/54, SB160-T, SB160E-G)?

A: All SB160 variants maintain the same 60 V reverse voltage and 1 A current ratings. Differences exist in forward voltage specifications (650 mV to 700 mV @ 1 A), manufacturer, packaging format, and compliance certifications. SB160-E3/54 offers the lowest forward voltage at 650 mV. All variants are electrically compatible with the MBR160.

Q: Are SR106 parts equivalent to the MBR160?

A: Yes. SR106 parts from Micro Commercial Co and Taiwan Semiconductor Corporation maintain identical 60 V reverse voltage and 1 A current ratings with 500 µA reverse leakage. Forward voltage is 700 mV @ 1 A. Operating temperature ranges vary by variant (some limited to -55°C to 125°C). All SR106 variants listed are electrically compatible with the MBR160.

Q: What is the significance of the forward voltage difference between MBR160 (750 mV) and SB160-E3/54 (650 mV)?

A: Lower forward voltage indicates improved efficiency and reduced power dissipation during forward conduction. The SB160-E3/54 specification of 650 mV is superior to the original 750 mV. This difference is acceptable for substitution as it represents improved performance, not degradation.

Q: Can I use SR206-AP as a substitute for the MBR160?

A: No. The SR206-AP is rated for 2 A average rectified current, compared to the MBR160 specification of 1 A. This higher current rating results in different electrical characteristics, including reverse leakage current of 1 mA @ 60 V (versus 500 µA @ 60 V for the MBR160). The SR206-AP is not electrically equivalent and is not suitable for direct substitution.

Q: What packaging options are available for MBR160 substitutes?

A: Substitute parts are available in multiple packaging formats: Bulk (loose components), Cut Tape (CT), and Tape & Reel (TR). All variants maintain the same through-hole axial package dimensions (DO-204AL, DO-41). Packaging format selection depends on assembly requirements and does not affect electrical compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: No. The original MBR160 is RoHS non-compliant. Most active substitutes (MBR160G, SB160-E3/54, SB160-T, SB160E-G, SR106-TP, SR106 R1G) are ROHS3 compliant. Some variants from Micro Commercial Co (SR106-AP, SR106-BP) do not specify RoHS status. Compliance requirements should be verified against your design specifications.

Q: What is the operating temperature range difference between variants?

A: The original MBR160 operates from -65°C to 150°C. Most active substitutes maintain this range. However, some Micro Commercial Co variants (SR106-AP, SR106-BP, SR106-TP) are limited to -55°C to 125°C. For applications requiring the full -65°C to 150°C range, select MBR160G, SB160-E3/54, SB160-T, SB160E-G, or SR106 R1G.

Q: How do I select between multiple equivalent parts?

A: Selection criteria include: (1) Product status and availability, (2) RoHS compliance requirements, (3) Operating temperature range requirements, (4) Forward voltage performance preferences, (5) Packaging format (Bulk, Cut Tape, Tape & Reel), and (6) Inventory availability. All listed parts meet the core electrical equivalence criteria of 60 V reverse voltage, 1 A current, and fast recovery characteristics.
