MB1S Bridge Rectifier Single Phase 100V 500mA Equivalent & Substitute Parts

Part Overview

The MB1S is a single-phase bridge rectifier rated for 100V peak reverse voltage and 500mA average rectified current in a 4-SOIC surface mount package. This component is classified as Not For New Designs, indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for legacy system maintenance, repair applications, and inventory replenishment where continued supply of the original part is limited or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB1S is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Voltage Rating: 100V peak reverse voltage (Vrrm)
• Current Rating: 500mA average rectified current (Io)
• Forward Voltage: 1V maximum at rated current
• Reverse Leakage: 5µA maximum at rated voltage
• Temperature Range: -55°C to 150°C junction temperature
• Package Type: 4-SOIC surface mount form factor
• Compliance: ROHS3 and REACH requirements

The MB1S-TP manufactured by Micro Commercial Co meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical ratings, temperature specifications, and package dimensions, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MB1S-TP is a direct parametric equivalent suitable for applications requiring 100V/500mA single-phase bridge rectification. Both the original MB1S and its substitute maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new assemblies and legacy system repairs.

Selection between available inventory should prioritize component availability and lead time. The MB1S maintains 9182 units in stock, while MB1S-TP has 5830 units available. Both parts carry identical electrical specifications and package dimensions, eliminating the need for circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can MB1S-TP replace MB1S in existing designs? A: Yes. The MB1S-TP is a parametric equivalent with identical voltage, current, temperature, and package specifications. Direct substitution is possible without circuit modification.

Q: What is the difference in forward voltage specification between the two parts? A: The MB1S specifies 1V @ 500mA, while MB1S-TP specifies 1V @ 400mA. Both maintain the same maximum forward voltage rating of 1V, ensuring compatible circuit performance.

Q: Are there packaging differences between MB1S and MB1S-TP? A: Both parts use the same 4-SOIC surface mount package (TO-269AA, 4-BESOP). PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet current compliance standards? A: Yes. Both MB1S and MB1S-TP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components? A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
