Substitute Part Grouping Explanation

Substitution for the MB110S-TP is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 100 V or higher
Current Rating: Average rectified current must be 1 A or higher
Diode Type: Single-phase bridge rectifier configuration
Technology: Schottky technology for forward voltage characteristics
Package Compatibility: TO-269AA, 4-BESOP surface mount package or equivalent footprint
Operating Temperature: Must support the required temperature range or be suitable for the application environment
Compliance: RoHS3 compliance and MSL rating

Substitute parts are grouped into two categories:

Direct Substitutes: Parts meeting or exceeding all electrical parameters with identical or compatible packaging.

Parametric Equivalents: Parts with identical core electrical specifications but potentially different packaging variants or manufacturer sources.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Obsolete Part Replacement)

CDBHM1100L-G and CDBHM1100L-HF are the primary recommended substitutes. Both are manufactured by Comchip Technology, maintain identical electrical specifications to the MB110S-TP (100 V, 1 A, 850 mV forward voltage), support the full operating temperature range (-55°C ~ 150°C), and use the same TO-269AA, 4-BESOP package. Both parts are active products with RoHS3 compliance and MSL 1 rating. CDBHM1100L-HF offers higher inventory availability (6349 pcs) compared to CDBHM1100L-G (959 pcs).

Alternative Substitutes (Higher Current Rating)

CDBHD2100-G and CDBHM2100L-G/CDBHM2100L-HF provide 2 A current rating, exceeding the 1 A requirement of the MB110S-TP. These parts are suitable for applications requiring additional current margin. Operating temperature is limited to -55°C ~ 125°C. All three maintain 100 V voltage rating and TO-269AA, 4-BESOP packaging. CDBHM2100L-HF has the highest inventory (10346 pcs).

Lower Priority Alternative

CDBHD1100L-G matches the 1 A current rating and TO-269AA package but features a lower forward voltage (750 mV @ 1 A) and reduced operating temperature range (-55°C ~ 125°C). This part is suitable only if the lower temperature ceiling is acceptable for the application.

Not Recommended

LMB110S-TP, while from the same manufacturer, uses a different package footprint (4-SMD, Gull Wing) and exhibits higher reverse leakage current (500 µA vs. 500 nA), making it unsuitable as a direct substitute without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can CDBHM1100L-G or CDBHM1100L-HF be used as direct replacements for MB110S-TP?

A: Yes. Both parts are direct substitutes. They maintain identical electrical specifications (100 V, 1 A, 850 mV forward voltage), use the same TO-269AA, 4-BESOP package, support the full -55°C ~ 150°C operating temperature range, and are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between CDBHM1100L-G and CDBHM1100L-HF?

A: Both parts are electrically and mechanically identical. The difference is in packaging format: CDBHM1100L-G is supplied in Tape & Reel (TR), while CDBHM1100L-HF is supplied in Cut Tape (CT) & Digi-Reel. CDBHM1100L-HF has significantly higher inventory availability.

Q: Can I use CDBHD2100-G or CDBHM2100L-G as substitutes?

A: These parts are suitable substitutes if your application can tolerate a 2 A current rating and reduced operating temperature range (-55°C ~ 125°C). The higher current rating provides design margin but is not required for 1 A applications. Verify temperature requirements before selection.

Q: Why does CDBHD1100L-G have a lower forward voltage (750 mV vs. 850 mV)?

A: Forward voltage variation is a normal characteristic of Schottky diodes across different manufacturers and process lots. CDBHD1100L-G's lower forward voltage may reduce power dissipation but is specified at the same 1 A current level. Verify thermal and efficiency requirements before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the MB110S-TP.

Q: What is the impact of the operating temperature difference between -55°C ~ 150°C and -55°C ~ 125°C?

A: The MB110S-TP and CDBHM1100L series support operation up to 150°C junction temperature, while CDBHD and CDBHM2100L series are rated to 125°C. If your application requires operation above 125°C, use CDBHM1100L-G or CDBHM1100L-HF. For applications below 125°C, all substitutes are acceptable.

Q: Can I use LMB110S-TP as a substitute?

A: LMB110S-TP is not recommended as a direct substitute. Although electrically similar, it uses a different package footprint (4-SMD, Gull Wing vs. TO-269AA, 4-BESOP) and exhibits higher reverse leakage current (500 µA vs. 500 nA). PCB redesign would be required for compatibility.
