Substitute Part Grouping Explanation

Substitute parts for the VS-MBRB4045CTRHM3 are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io) (per Diode): 20 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 20 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 1 mA @ 45 V
• Operating Temperature - Junction: -65°C ~ 150°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Base Product Number: MBRB4045

Compliance Parameters (Must Match Exactly):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts that differ only in packaging format (Tape & Reel versus Tube) while maintaining identical electrical and mechanical specifications are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—VS-MBRB4045CTRHM3, VS-MBRB4045CTL-M3, and VS-MBRB4045CTLHM3—are parametric equivalents with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and inventory requirements rather than technical performance.

VS-MBRB4045CTRHM3 is suitable for high-volume automated assembly processes requiring tape and reel packaging. This format is optimized for pick-and-place equipment and provides 968 pieces in current inventory.

VS-MBRB4045CTL-M3 is the preferred choice when tape and reel packaging is required and maximum inventory availability is a priority. This part number maintains identical specifications with 9094 pieces in stock, providing superior supply chain flexibility.

VS-MBRB4045CTLHM3 is appropriate for manual assembly operations or applications where tube packaging is compatible with existing handling procedures. This variant offers 1538 pieces in inventory and maintains full electrical and mechanical equivalence.

All three parts carry active product status, AEC-Q101 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1), confirming suitability for automotive and industrial applications across the specified operating temperature range of -65°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Are VS-MBRB4045CTL-M3 and VS-MBRB4045CTLHM3 direct replacements for VS-MBRB4045CTRHM3?

A: Yes. All three part numbers are parametric equivalents with identical electrical characteristics, mechanical dimensions, and compliance certifications. The only difference is packaging format: tape and reel versus tube. PCB layout, thermal management, and circuit performance remain unchanged across all three variants.

Q: What is the difference between tape and reel packaging and tube packaging?

A: Tape and reel packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume manufacturing. Tube packaging is used for manual assembly, lower-volume production, or applications where components are handled individually. Both formats contain the same component with identical specifications.

Q: Can I substitute VS-MBRB4045CTL-M3 for VS-MBRB4045CTRHM3 in an existing design?

A: Yes. Both parts are tape and reel packaged with identical electrical and mechanical specifications. No design changes are required. The substitution is direct at the component level.

Q: Can I use VS-MBRB4045CTLHM3 (tube packaging) in an automated assembly line designed for tape and reel components?

A: No. Tube packaging is incompatible with automated pick-and-place equipment configured for tape and reel format. Use either VS-MBRB4045CTRHM3 or VS-MBRB4045CTL-M3 for automated assembly processes.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All three variants carry AEC-Q101 qualification and automotive grade designation, confirming compliance with automotive industry standards across the full operating temperature range of -65°C to 150°C.

Q: What is the significance of the MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All three parts can be stored and handled under standard warehouse conditions without special moisture control procedures, simplifying inventory management and reducing component preparation time.

Q: Are there any electrical performance differences between the three part numbers?

A: No. All three parts have identical electrical specifications: 45 V reverse voltage rating, 20 A average rectified current per diode, 600 mV forward voltage at 20 A, fast recovery switching characteristics, and 1 mA reverse leakage current at 45 V.
