MBR1545CT-Y Equivalent & Substitute Parts

Part Overview

The MBR1545CT-Y is a diode array rectifier manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode design rated for 45 V DC reverse voltage and 15 A average rectified current per diode. The device is packaged in a TO-220-3 through-hole configuration and is classified as Active product status with full RoHS3 compliance.

Substitute parts are identified to provide alternative sourcing options when the primary MBR1545CT-Y becomes unavailable or when inventory constraints require component alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR1545CT-Y is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Package / Case: TO-220-3
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

The MBR1545CT manufactured by Solid State Inc. qualifies as a direct substitute based on these parameters. Both devices share identical voltage and current ratings, identical package configuration, and equivalent regulatory compliance status. The substitute part maintains the same through-hole mounting requirement and RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

Both the MBR1545CT-Y and MBR1545CT meet the mandatory electrical and mechanical requirements for direct substitution based on voltage rating, current capacity, package type, and mounting configuration. Both devices maintain Active product status and ROHS3 compliance certification.

The MBR1545CT substitute part is available in significantly higher inventory (23,936 pcs) compared to the primary part (967 pcs), providing improved supply chain availability. Both parts carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Selection between these parts should be based on application-specific requirements regarding diode configuration (1 Pair Common Cathode versus 2 Independent) and recovery speed characteristics (Standard Recovery versus Fast Recovery). The substitute part's Schottky technology and faster recovery speed may provide performance advantages in high-frequency switching applications, while the main part's standard technology may be preferred for linear rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the MBR1545CT be used as a direct replacement for the MBR1545CT-Y?

A: The MBR1545CT qualifies as a substitute based on matching voltage rating (45 V), current rating (15 A per diode), package configuration (TO-220-3), and mounting type (through hole). Both devices are RoHS3 compliant and Active status. However, the diode configuration differs (1 Pair Common Cathode versus 2 Independent) and recovery speed characteristics differ (Standard versus Fast Recovery). Application circuit requirements must be evaluated to confirm compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Diode Configuration—MBR1545CT-Y uses 1 Pair Common Cathode while MBR1545CT uses 2 Independent configuration; (2) Technology—MBR1545CT-Y uses Standard technology while MBR1545CT uses Schottky technology; (3) Recovery Speed—MBR1545CT-Y has Standard Recovery (>500ns) while MBR1545CT has Fast Recovery (≤500ns). Voltage, current, and package specifications are identical.

Q: Are both parts suitable for the same PCB layout?

A: Both parts use the TO-220-3 package with through-hole mounting, allowing installation in the same PCB footprint. Pin configuration compatibility must be verified against the specific application circuit, particularly regarding the different diode configurations (common cathode versus independent).

Q: What is the inventory status for these parts?

A: The MBR1545CT-Y has 967 pcs in stock. The MBR1545CT substitute has 23,936 pcs in stock, providing significantly greater availability for immediate procurement.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications. REACH status differs—MBR1545CT-Y is REACH Unaffected while MBR1545CT is Vendor Undefined.
