Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1635 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 35 V
• Current - Average Rectified (Io): 16 A
• Voltage - Forward (Vf) (Max) @ If: 630 mV @ 16 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 35 V

Mechanical Equivalence Criteria:

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 150°C
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and mechanical compatibility. Differences exist only in product status, packaging format (tube versus tape & reel), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

MBRB1635-E3/45 is a parametric equivalent available in tube packaging with Last Time Buy status and ROHS3 compliance. This part number represents a transitional option for applications requiring RoHS-compliant components while maintaining the original electrical and mechanical specifications.

VS-MBRB1635TRR-M3 is the recommended primary substitute, offering Active product status with ROHS3 compliance and tape & reel packaging suitable for automated assembly processes. This part number provides long-term availability and regulatory compliance for new designs and ongoing production requirements.

Both substitute parts maintain full electrical and thermal equivalence to the obsolete MBRB1635, with identical voltage ratings, current capacity, forward voltage characteristics, and operating temperature range. Selection between MBRB1635-E3/45 and VS-MBRB1635TRR-M3 depends on packaging requirements and procurement volume specifications.

Frequently Asked Questions (FAQ)

Q: Can MBRB1635-E3/45 and VS-MBRB1635TRR-M3 be used interchangeably with MBRB1635?

A: Yes. Both substitute parts maintain identical electrical specifications (35 V reverse voltage, 16 A average rectified current, 630 mV forward voltage at 16 A) and mechanical compatibility (TO-263AB D2PAK surface mount package). Direct substitution is supported without circuit modification.

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

A: Tube packaging (MBRB1635-E3/45) is suitable for manual assembly and lower-volume applications. Tape & reel packaging (VS-MBRB1635TRR-M3) is designed for automated pick-and-place assembly processes and higher production volumes. Both formats contain identical components with equivalent electrical performance.

Q: Why is the original MBRB1635 classified as obsolete?

A: The MBRB1635 is obsolete due to product lifecycle management by the manufacturer. Equivalent substitute parts with improved product status and regulatory compliance are available to support ongoing design and procurement requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MBRB1635-E3/45 and VS-MBRB1635TRR-M3 are ROHS3 compliant, whereas the original MBRB1635 is RoHS non-compliant. This compliance improvement supports regulatory requirements for new designs and markets with RoHS mandates.

Q: What is the product status difference between the substitute parts?

A: MBRB1635-E3/45 carries Last Time Buy status, indicating limited future availability. VS-MBRB1635TRR-M3 carries Active status, indicating ongoing production and long-term availability. For new designs, VS-MBRB1635TRR-M3 is the preferred selection.

Q: Are there any thermal or electrical performance differences between the parts?

A: No. All three part numbers maintain identical operating temperature range (-65°C to 150°C), reverse leakage current (200 µA @ 35 V), and fast recovery speed characteristics (≤ 500ns, > 200mA). Performance is equivalent across all electrical and thermal parameters.
