MB2S Bridge Rectifier Single Phase 200V 500mA Equivalent & Substitute Parts

Part Overview

The MB2S is a single-phase bridge rectifier rated for 200V peak reverse voltage with 500mA average rectified current, packaged in a 4-SOIC surface mount configuration. Manufactured by onsemi, this component is classified as Not For New Designs, making identification of active equivalent and substitute parts essential for ongoing production and maintenance applications. The MB2S serves as a standard rectification solution in power supply circuits requiring moderate current handling at 200V operation.

Substitute Part Grouping Explanation

Substitution eligibility for the MB2S is determined by strict alignment across the following critical parameters:

Diode Type: Single Phase
Voltage - Peak Reverse (Max): 200 V
Current - Average Rectified (Io): 500 mA
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Manufacturer Substitutes maintain identical electrical specifications and package compatibility with the MB2S, differing only in manufacturer or packaging format (tape & reel vs. cut tape).

Parametric Equivalents meet all critical electrical parameters but may have minor variations in forward voltage specifications or packaging designations while maintaining functional interchangeability within the defined operating envelope.

Engineering Selection Recommendations

MB2S-E3/80 (Vishay) is the primary recommended substitute. This part maintains Active product status, identical electrical specifications, and the same TO-269AA package footprint. With 20487 units in stock, it provides the highest availability for production continuity.

MB2S-E3/45 (Vishay) serves as a secondary option with Active status and equivalent specifications, though with lower inventory (1407 units).

B2S-E3/80 (Vishay) is a parametric equivalent with identical forward voltage specification at 500mA and Active status, suitable for applications where the exact forward voltage characteristic is critical. Inventory is limited to 720 units.

MB2S-TP (Micro Commercial Co) maintains Not For New Designs status matching the original MB2S, with the highest inventory level (44100 units). This part is suitable for legacy system maintenance where design status alignment is required.

CBRHD-02 TR13 PBFREE (Central Semiconductor Corp) is an Active substitute with an extended lower operating temperature limit (-65°C vs. -55°C) and alternative package geometry (4-SMD, Gull Wing). This part is suitable for applications requiring enhanced low-temperature performance or where the alternative package footprint is acceptable.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and equivalent reverse leakage characteristics.

Frequently Asked Questions (FAQ)

Q: Can MB2S-E3/80 be used as a direct replacement for MB2S in existing designs?

A: Yes. MB2S-E3/80 maintains identical electrical specifications (200V, 500mA, 1V forward voltage @ 400mA), the same TO-269AA package footprint, and equivalent thermal characteristics. The primary difference is manufacturer (Vishay vs. onsemi) and product status (Active vs. Not For New Designs).

Q: What is the difference between MB2S-E3/45 and MB2S-E3/80?

A: Both parts are manufactured by Vishay with identical electrical specifications and package geometry. The designations reflect different packaging formats: MB2S-E3/45 is supplied in Tube packaging, while MB2S-E3/80 is supplied in Cut Tape & Digi-Reel format. Electrical performance is equivalent.

Q: Is CBRHD-02 TR13 PBFREE compatible with the MB2S footprint?

A: CBRHD-02 TR13 PBFREE uses a 4-SMD Gull Wing package geometry, which differs from the MB2S TO-269AA package. PCB layout verification is required before substitution. The part meets all electrical specifications and offers extended low-temperature operation (-65°C minimum vs. -55°C).

Q: Why does B2S-E3/80 show 1V forward voltage @ 500mA while other substitutes show 1V @ 400mA?

A: B2S-E3/80 is specified with forward voltage measured at the full 500mA rated current, matching the MB2S specification exactly. Other substitutes are specified at 400mA. Both meet the 1V maximum specification and are functionally equivalent within the operating envelope.

Q: Which substitute offers the best inventory availability?

A: MB2S-TP (Micro Commercial Co) provides the highest inventory at 44100 units. For Active product status, MB2S-E3/80 (Vishay) offers the best availability at 20487 units.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original MB2S specifications.
