Key Parameters

Substitute Part Grouping Explanation

Substitution of the BCR5AS-12B#B01 is determined by the following critical parameters:

• Voltage - Off State: 600 V (minimum requirement)
• Current - On State (It (RMS)): 5 A minimum (equal or higher ratings acceptable)
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63 (physical and electrical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Operating Temperature Range: -40°C ~ 150°C (TJ) (thermal envelope)
• Gate Trigger Voltage (Vgt) and Current (Igt): Within specified maximums for circuit operation

The QJ6006DH4RP from Littelfuse Inc. meets these substitution criteria with a 600V off-state voltage, 6A on-state current rating (exceeds 5A requirement), identical package type, and matching operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The QJ6006DH4RP is a direct substitute for the BCR5AS-12B#B01 based on electrical and mechanical compatibility. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements. The QJ6006DH4RP maintains active product status with confirmed inventory availability (3281 Pcs), whereas the BCR5AS-12B#B01 is discontinued. The substitute part exceeds the original specifications in current rating (6A vs. 5A) and surge current capacity, providing equivalent or superior performance in the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can the QJ6006DH4RP directly replace the BCR5AS-12B#B01 on existing PCBs?

A: Yes. Both components use identical TO-252-3 (DPAK) packaging with the same pinout and footprint. No PCB modifications are required.

Q: What is the difference between a Standard TRIAC and an Alternistor - Snubberless TRIAC?

A: The BCR5AS-12B#B01 is a Standard TRIAC, while the QJ6006DH4RP is an Alternistor - Snubberless variant. Both are functionally compatible for AC switching applications. The Snubberless design may reduce the need for external snubber circuits in certain applications.

Q: Are there any thermal or current rating concerns when substituting?

A: No. The QJ6006DH4RP has a higher on-state current rating (6A vs. 5A) and higher surge current capacity (60A, 72A vs. 50A @ 60Hz), making it suitable for the same or more demanding applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BCR5AS-12B#B01 and QJ6006DH4RP are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8541.30.0080) codes.

Q: What is the operating temperature range for both parts?

A: Both components operate across the same temperature range: -40°C to 150°C (TJ), ensuring thermal compatibility in equivalent circuit designs.
