Key Parameters

Substitute Part Grouping Explanation

Substitute components for the BD1040CS_S2_00001 must satisfy the following criteria based on allowed electrical and mechanical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 10 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 700 mV @ 5 A
• Current - Reverse Leakage @ Vr: Equal to or less than 50 µA @ 40 V
• Operating Temperature - Junction: Range must encompass or exceed -55°C ~ 150°C
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The VS-6CWQ04FNTR-M3 is identified as a substitute part. However, this component exhibits a reduced current rating of 3.5 A per diode, which is below the 10 A specification of the main part. This substitution is valid only in applications where the circuit design permits operation at the lower current rating without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The VS-6CWQ04FNTR-M3 is an active product manufactured by Vishay General Semiconductor - Diodes Division and maintains full compliance with ROHS3 and MSL 1 requirements, matching the regulatory status of the obsolete BD1040CS_S2_00001.

Both components share identical mechanical compatibility through the TO-252-3 DPAK package and identical electrical specifications for voltage rating and switching speed. The substitute part is suitable for applications where the circuit design operates within the 3.5 A per diode current envelope. Applications requiring the full 10 A current capacity of the original part require alternative solutions beyond the provided substitute list.

The substitute part is available in active production with significantly higher inventory levels (12,700 pieces) compared to the obsolete original part (3,899 pieces), ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the VS-6CWQ04FNTR-M3 be used as a direct replacement for the BD1040CS_S2_00001?

A: The VS-6CWQ04FNTR-M3 is mechanically and electrically compatible in terms of package, voltage rating, and switching characteristics. However, the substitute part is rated for 3.5 A per diode versus the original 10 A rating. Direct substitution is valid only if the application circuit operates within the 3.5 A current specification.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (10 A versus 3.5 A), forward voltage characteristics (700 mV @ 5 A versus 530 mV @ 3 A), reverse leakage current (50 µA versus 2 mA at 40 V), and product status (obsolete versus active). Both parts share identical package, voltage rating, and switching speed specifications.

Q: Are both parts RoHS compliant?

A: Yes, both the BD1040CS_S2_00001 and VS-6CWQ04FNTR-M3 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Cut Tape (CT) packaging provides individual component strips suitable for smaller quantities and manual handling. Tape & Reel (TR) packaging provides components on continuous reels optimized for automated assembly equipment. Both formats contain identical components; packaging type affects handling and assembly methodology only.

Q: Can I use the substitute part in high-current applications requiring 10 A?

A: No. The VS-6CWQ04FNTR-M3 is rated for 3.5 A per diode maximum. Using this part in applications requiring 10 A operation will result in component overstress and potential failure. Alternative parts with 10 A or higher current ratings must be sourced for such applications.

Q: Are the operating temperature ranges compatible?

A: Both parts specify a maximum junction temperature of 150°C. The original part specifies a minimum of -55°C. The substitute part specification provides only the maximum temperature. Both parts are suitable for standard industrial temperature ranges.
