MB14S-TP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB14S-TP is a single-phase bridge rectifier utilizing Schottky technology, rated for 40 V peak reverse voltage and 1 A average rectified current. Designed for surface mount applications in the MBS-1 package, this component is classified as Obsolete. Due to its obsolete status and limited availability for new production runs, identifying equivalent substitute parts is essential for design continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB14S-TP is determined by the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Technology: Schottky technology for low forward voltage characteristics
• Voltage Rating: 40 V peak reverse voltage (Vrrm)
• Current Rating: 1 A average rectified current (Io)
• Forward Voltage: Maximum 500 mV at rated current
• Reverse Leakage: 500 µA at 40 V
• Temperature Range: -55°C to 150°C junction temperature
• Mounting: Surface mount configuration
• Compliance: ROHS3 compliant, REACH unaffected

The LMB14S-TP meets all critical electrical parameters and compliance requirements, making it a valid substitute despite differences in package designation and forward voltage specification at different test conditions.

Parameter Comparison

Engineering Selection Recommendations

The LMB14S-TP is electrically and mechanically compatible with the MB14S-TP for applications requiring a 40 V, 1 A single-phase Schottky bridge rectifier. Both parts maintain identical voltage and current ratings, temperature operating range, and regulatory compliance status (ROHS3 compliant, REACH unaffected).

The LMB14S-TP is currently available in higher inventory quantities (20,456 pcs) compared to the MB14S-TP (9,700 pcs), providing improved supply chain accessibility. Both parts are classified as end-of-life or restricted from new designs, indicating that long-term availability should be evaluated for production planning.

Frequently Asked Questions (FAQ)

Q: Can the LMB14S-TP directly replace the MB14S-TP in existing designs?

A: Yes. Both parts share identical electrical specifications for voltage rating (40 V), current rating (1 A), reverse leakage (500 µA @ 40 V), and operating temperature range (-55°C to 150°C). Both are Schottky single-phase bridge rectifiers with surface mount configuration and ROHS3 compliance.

Q: What is the difference in forward voltage between these parts?

A: The MB14S-TP specifies 500 mV maximum forward voltage at 1 A, while the LMB14S-TP specifies 550 mV maximum at 500 mA. These measurements are taken at different test conditions. Both values remain within acceptable operating parameters for typical bridge rectifier applications.

Q: Are there package differences between MB14S-TP and LMB14S-TP?

A: The MB14S-TP uses the MBS-1 package (TO-269AA, 4-BESOP), while the LMB14S-TP uses the LMBS-1 package (4-SMD, Gull Wing). Both are surface mount configurations with identical pin counts and electrical functionality. PCB layout compatibility should be verified based on specific package footprints.

Q: What is the significance of the product status difference?

A: The MB14S-TP is classified as Obsolete, while the LMB14S-TP is classified as Not For New Designs. Both designations indicate end-of-life status. For new production designs, alternative active bridge rectifier products should be evaluated for long-term supply assurance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MB14S-TP and LMB14S-TP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
