Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

VS-MBRB2045CTL-M3, VS-MBRB2045CTR-M3, and VS-MBRB2045CT-M3 are direct replacements for the discontinued VS-MBRB2045CTTRLP. All three parts are manufactured by Vishay and maintain identical electrical parameters. Selection between these variants depends on packaging format requirements: Tape & Reel (TR) for automated assembly or Tube for manual handling. All three are ROHS3 compliant with MSL 1 rating.

Cross-Manufacturer Equivalents (Identical Electrical Performance):

STPS2045CG-TR and STPS2045CGY-TR from STMicroelectronics provide identical electrical specifications to the original part. Both maintain 45 V reverse voltage, 10 A current rating, and 570 mV forward voltage. STPS2045CGY-TR includes automotive qualification (AEC-Q101) and extended operating temperature range (-40°C ~ 175°C) compared to the original part's -65°C ~ 150°C range. Both are ROHS3 compliant with MSL 1 rating.

Higher Performance Alternative:

DSA30C45PC-TRL from IXYS is a manufacturer-recommended alternative that exceeds the original specifications. This part maintains the 45 V reverse voltage and TO-263-3 D2PAK package but provides 15 A current rating (versus 10 A) and extended temperature range (-55°C ~ 175°C). This part is suitable for applications requiring higher current capacity or wider temperature operation. ROHS3 compliant with MSL 1 rating.

All substitute parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification, matching the regulatory status of the original part.

Frequently Asked Questions (FAQ)

Q: Can VS-MBRB2045CTL-M3 directly replace VS-MBRB2045CTTRLP?

A: Yes. VS-MBRB2045CTL-M3 is a direct replacement. Both parts share identical electrical specifications: 45 V reverse voltage, 10 A current rating, 570 mV forward voltage at 10 A, and TO-263-3 D2PAK package. The primary difference is packaging format: the original uses Tape & Reel, while CTL-M3 also uses Tape & Reel. Both are ROHS3 compliant with unlimited moisture sensitivity level.

Q: What is the difference between VS-MBRB2045CTR-M3 and VS-MBRB2045CT-M3?

A: Both parts are electrically identical to the original VS-MBRB2045CTTRLP. The difference is packaging format: VS-MBRB2045CTR-M3 is supplied in Tape & Reel (TR) format suitable for automated pick-and-place assembly, while VS-MBRB2045CT-M3 is supplied in Tube format suitable for manual handling and lower-volume applications.

Q: Can STPS2045CGY-TR replace VS-MBRB2045CTTRLP in automotive applications?

A: Yes. STPS2045CGY-TR maintains identical electrical specifications (45 V, 10 A, 570 mV forward voltage) and TO-263-3 D2PAK package compatibility. STPS2045CGY-TR includes automotive qualification (AEC-Q101) and operates across -40°C ~ 175°C, providing a wider temperature range than the original part's -65°C ~ 150°C specification. Both are ROHS3 compliant.

Q: Is DSA30C45PC-TRL a suitable substitute for the original part?

A: DSA30C45PC-TRL is compatible from a package and voltage perspective (45 V, TO-263-3 D2PAK). However, this part exceeds the original specifications with 15 A current rating versus 10 A, and 750 mV forward voltage at 15 A versus 570 mV at 10 A. DSA30C45PC-TRL is suitable for applications requiring higher current capacity or enhanced performance margins while maintaining the same package footprint and voltage rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (VS-MBRB2045CTL-M3, VS-MBRB2045CT-M3, VS-MBRB2045CTR-M3, STPS2045CG-TR, STPS2045CGY-TR, and DSA30C45PC-TRL) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the regulatory status of the original VS-MBRB2045CTTRLP.

Q: What packaging formats are available for equivalent parts?

A: Equivalent parts are available in three packaging formats: Tape & Reel (TR) for automated assembly, Tube for manual handling, and Cut Tape (CT) & Digi-Reel® for mixed-volume applications. Selection depends on assembly process requirements and order quantities.

Q: Do all substitute parts use the same TO-263-3 D2PAK package?

A: Yes. All substitute parts use TO-263-3 D2PAK (2 Leads + Tab) surface mount package, ensuring mechanical and thermal compatibility with the original part's PCB footprint and thermal management design.
