Substitute Part Grouping Explanation

Substitution of the VS-MBRB1635PBF is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the original VS-MBRB1635PBF, differing only in packaging format (tube versus tape & reel) and product status classification.

Engineering Selection Recommendations

Primary Substitute: VS-MBRB1635-M3

The VS-MBRB1635-M3 is the recommended primary substitute for the discontinued VS-MBRB1635PBF. This part maintains complete electrical and mechanical equivalence while offering Active product status classification. The part is supplied in Tube packaging format and maintains the highest inventory availability at 6780 pieces. ROHS3 compliance and MSL 1 rating ensure compatibility with standard manufacturing and storage protocols.

Secondary Substitute: VS-MBRB1635TRR-M3

The VS-MBRB1635TRR-M3 provides an equivalent alternative with Active product status, supplied in Tape & Reel (TR) format suitable for automated assembly operations. This packaging format is appropriate for high-volume production environments. Electrical and mechanical specifications remain identical to the original part.

Tertiary Substitute: MBRB1635-E3/45

The MBRB1635-E3/45 is classified as Last Time Buy and maintains complete parametric equivalence. This part is supplied in Tube packaging with 1380 pieces in inventory. Selection of this part should account for its Last Time Buy status, indicating limited future availability.

All three substitute parts satisfy the electrical performance requirements, mechanical compatibility, and regulatory compliance standards of the original VS-MBRB1635PBF.

Frequently Asked Questions (FAQ)

Q: Can VS-MBRB1635-M3 be used as a direct replacement for VS-MBRB1635PBF?

A: Yes. The VS-MBRB1635-M3 is a direct electrical and mechanical equivalent. Both parts share identical voltage ratings (35V), current ratings (16A), forward voltage characteristics (630 mV @ 16 A), and package specifications (TO-263AB D2PAK). The primary difference is packaging format (Tube versus standard) and product status (Active versus Discontinued).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and small-volume production. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly systems and high-volume manufacturing. Both formats contain identical components with identical electrical specifications. Selection depends on assembly methodology and production volume requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—VS-MBRB1635-M3, MBRB1635-E3/45, and VS-MBRB1635TRR-M3—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original VS-MBRB1635PBF specifications.

Q: What does "Last Time Buy" status mean for MBRB1635-E3/45?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this part number. Existing inventory is available for purchase, but no future production is planned. This part remains electrically and mechanically equivalent but should be considered a secondary option due to limited future availability.

Q: Can these parts be used interchangeably in existing circuit designs?

A: Yes. All substitute parts maintain identical electrical parameters (voltage, current, forward voltage, leakage current, and speed classification) and mechanical compatibility (TO-263AB package, surface mount configuration, operating temperature range). No circuit redesign or board layout modification is required.

Q: What is the significance of the 1400pF capacitance specification listed for some parts?

A: The capacitance specification (1400pF @ 5V, 1MHz) is provided for VS-MBRB1635-M3 and VS-MBRB1635TRR-M3 but not specified for the original VS-MBRB1635PBF or MBRB1635-E3/45. This parameter does not affect substitution eligibility, as all parts maintain identical core electrical performance characteristics required for rectification applications.
