Engineering Selection Recommendations

All listed substitute parts are active products with RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the SR106-TP.

SB160-T (Diodes Incorporated) provides the closest functional match to the SR106-TP, offering identical forward voltage specification (700 mV @ 1 A) and DO-41 package format. This part is supplied in Tape & Reel packaging, matching the original part's delivery format.

SB160-E3/73 (Vishay General Semiconductor) offers superior forward voltage performance (650 mV @ 1 A) and is supplied in DO-204AL (DO-41) package format. This part is available in Cut Tape packaging and supports extended operating temperature range (-65°C ~ 150°C).

MBR160RLG (onsemi) provides the highest inventory availability (16,700 pieces) and extended operating temperature range (-65°C ~ 150°C). This part is supplied in Axial package format with Cut Tape packaging. Forward voltage is specified at 750 mV @ 1 A.

MBR160G (onsemi) is available in Bulk packaging with extended operating temperature range (-65°C ~ 150°C). Forward voltage is specified at 750 mV @ 1 A. This part is supplied in Axial package format.

Selection between substitute parts depends on specific application requirements regarding forward voltage tolerance, operating temperature range, package format compatibility with assembly equipment, and delivery format preferences.

Frequently Asked Questions (FAQ)

Q: Can MBR160G replace SR106-TP in all applications?

A: MBR160G meets all core electrical specifications (60V, 1A, fast recovery Schottky technology, 500 µA reverse leakage). The primary differences are forward voltage (750 mV vs. 700 mV) and package format (Axial vs. DO-41). Substitution is valid when the application circuit tolerates the additional 50 mV forward voltage drop and when Axial package geometry is compatible with the PCB layout.

Q: What is the difference between DO-41 and Axial package formats?

A: Both are through-hole packages for axial-lead diodes. DO-41 and DO-204AL are equivalent designations for the same physical package. Axial refers to the lead configuration where both leads extend along the component axis. All listed substitute parts use compatible through-hole axial-lead packages suitable for wave soldering and manual insertion.

Q: Why does SB160-E3/73 have lower forward voltage than the original part?

A: Forward voltage variation is a normal characteristic across different manufacturers' Schottky diode designs. SB160-E3/73 specifies 650 mV @ 1 A compared to SR106-TP's 700 mV @ 1 A. Lower forward voltage reduces power dissipation in the diode, which is beneficial in most applications. Substitution is valid when the application circuit design does not depend on the specific forward voltage value of the original part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (MBR160G, MBR160RLG, SB160-E3/73, and SB160-T) are RoHS3 compliant and REACH unaffected, matching the regulatory status of the SR106-TP.

Q: What is the significance of operating temperature range differences?

A: SR106-TP specifies -55°C ~ 125°C junction temperature range, while all substitute parts specify -65°C ~ 150°C. The substitute parts support wider temperature operation. If the application operates within the SR106-TP temperature range, all substitutes are suitable. If the application requires extended temperature operation beyond -55°C or above 125°C, the substitute parts provide additional margin.

Q: Can I use MBR160RLG in place of SR106-TP if my assembly equipment handles Axial packages?

A: Yes. MBR160RLG meets all electrical specifications and is supplied in compatible through-hole Axial package format. The Cut Tape packaging format is suitable for automated pick-and-place assembly equipment. Substitution is valid when the assembly process supports Axial package handling.

Q: Which substitute part has the best availability?

A: MBR160RLG has the highest inventory level at 16,700 pieces. This part is suitable for high-volume production requirements and offers extended lead time protection.
