Key Parameters

Substitute Part Grouping Explanation

Substitution of the TBSL40M-TP is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Voltage Rating: 1 kV peak reverse voltage (Vrrm)
• Current Rating: 4 A average rectified current (Io)
• Mounting Technology: Surface mount construction
• Compliance: RoHS3 certification and MSL 1 rating

The CD-DF410S manufactured by Bourns Inc. meets all substitution criteria. Both components share identical voltage and current ratings, operate across overlapping temperature ranges, and maintain equivalent RoHS3 and MSL compliance. The CD-DF410S is currently in active production status, providing long-term availability for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The CD-DF410S is the qualified substitute for the obsolete TBSL40M-TP based on electrical parameter equivalence and compliance alignment. Both components maintain identical voltage and current specifications, reverse leakage characteristics, and regulatory certifications (RoHS3, MSL 1). The CD-DF410S offers extended operating temperature capability (175°C junction temperature versus 150°C ambient for TBSL40M-TP) and active production status, ensuring sustained component availability. Package geometry differences (4-SMD Flat Leads versus Chip Concave Terminals) require PCB layout verification during design transition.

Frequently Asked Questions (FAQ)

Q: What makes CD-DF410S a valid substitute for TBSL40M-TP?

A: Both components are single-phase bridge rectifiers with identical 1 kV voltage ratings and 4 A current ratings. They share equivalent reverse leakage specifications, RoHS3 compliance, and MSL 1 moisture sensitivity ratings. The CD-DF410S maintains active production status, addressing the obsolescence of the TBSL40M-TP.

Q: Are there package compatibility concerns between these parts?

A: The TBSL40M-TP uses 4-SMD Flat Leads packaging, while the CD-DF410S uses Chip Concave Terminals. PCB footprint and land pattern verification is required before design implementation to ensure mechanical and electrical compatibility.

Q: How do forward voltage characteristics compare?

A: The TBSL40M-TP specifies 1 V maximum forward voltage at 4 A, while the CD-DF410S specifies 950 mV maximum at 2 A. Both values fall within acceptable ranges for standard bridge rectifier applications. Circuit performance impact depends on specific load conditions and thermal management design.

Q: What is the temperature operating range difference?

A: The TBSL40M-TP operates from -55°C to 150°C ambient, while the CD-DF410S operates from -55°C to 175°C junction temperature. The CD-DF410S provides extended high-temperature capability, beneficial for thermally demanding applications.

Q: Are regulatory certifications equivalent?

A: Both components are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity). Regulatory and environmental compliance requirements are met by either component for equivalent applications.
