BCR5AS-14LJ#B00 Equivalent & Substitute Parts

Part Overview

The BCR5AS-14LJ#B00 is a TRIAC rated at 700V and 5A, manufactured by Renesas Electronics Corporation. This component is classified as discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design and procurement activities. TRIACs in this voltage and current class are used in AC switching applications requiring bidirectional control. The discontinuation status necessitates identification of functionally compatible alternatives that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BCR5AS-14LJ#B00 is determined by the following electrical and mechanical parameters:

• Off-State Voltage Rating: The substitute must equal or exceed 700V to maintain voltage margin in the application circuit.
• On-State Current Rating: The substitute must equal or exceed 5A RMS to handle the design load without thermal stress.
• Device Type: Must be a TRIAC to provide bidirectional AC switching functionality.
• Compliance Standards: RoHS3 compliance and MSL rating must be maintained for manufacturing and environmental requirements.
• Packaging and Mounting: Physical compatibility with the original circuit layout.

The identified substitute Q8006DH4RP meets these criteria with a higher voltage rating (800V) and higher current rating (6A), providing design margin while maintaining functional equivalence.

Engineering Selection Recommendations

The Q8006DH4RP from Littelfuse Inc. is a direct functional substitute for the BCR5AS-14LJ#B00. Selection is based on the following factors:

• Electrical Compatibility: The Q8006DH4RP exceeds the voltage and current requirements of the original part, providing design margin without compromising performance.
• Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring manufacturing process compatibility.
• Product Availability: The Q8006DH4RP is listed as Active, ensuring long-term procurement availability compared to the discontinued BCR5AS-14LJ#B00.
• REACH Compliance: The Q8006DH4RP is REACH Unaffected, eliminating potential regulatory constraints associated with the original part's REACH Affected status.
• Packaging Consideration: The Q8006DH4RP uses Surface Mount packaging (TO-252 DPAK), which may require circuit layout verification if the original design used through-hole or different package geometry.

Frequently Asked Questions (FAQ)

Q: Can the Q8006DH4RP directly replace the BCR5AS-14LJ#B00 in my circuit?

A: Yes, the Q8006DH4RP is electrically compatible as a substitute. The higher voltage (800V vs. 700V) and current (6A vs. 5A) ratings provide design margin. However, verify that the Surface Mount TO-252 package is compatible with your PCB layout and assembly process.

Q: What is the significance of the higher voltage and current ratings on the Q8006DH4RP?

A: Higher ratings provide operational margin, reducing thermal stress and extending component life under the same load conditions. The application will operate safely within the original design parameters while benefiting from improved reliability.

Q: Does the REACH Unaffected status of the Q8006DH4RP affect compatibility?

A: No. REACH Unaffected status is advantageous, as it eliminates regulatory documentation requirements associated with REACH Affected components. This simplifies compliance for end-use applications.

Q: Are there packaging differences I need to consider?

A: The Q8006DH4RP uses TO-252 (DPAK) Surface Mount packaging. If your original design used a different package type, PCB layout and assembly process modifications may be required. Verify pin configuration and thermal pad requirements with your manufacturing team.

Q: What is the difference between a standard TRIAC and a TRIAC Alternistor?

A: The Q8006DH4RP is specified as a TRIAC Alternistor - Snubberless design. This classification indicates optimized gate trigger characteristics and reduced EMI generation. It functions as a TRIAC for AC switching applications and is compatible with standard TRIAC circuit designs.

Q: Is the gate trigger voltage (Vgt) of 1.3V on the Q8006DH4RP compatible with my control circuit?

A: The gate trigger voltage of 1.3V is typical for modern TRIAC designs and is compatible with standard logic-level gate drive circuits. Verify that your gate drive circuit can supply the specified gate trigger current (Igt) of 35mA maximum.
