Q6016NH4TP TRIAC Alternistor 600V 16A Equivalent & Substitute Parts
Part Overview
The Q6016NH4TP is a TRIAC Alternistor (Snubberless) manufactured by Littelfuse Inc., rated for 600V off-state voltage and 16A on-state current in a surface mount TO-263 (D2PAK) package. This component is active in production with 1038 units in stock. The device operates across a temperature range of -40°C to 125°C and is RoHS3 compliant with MSL Level 1 (unlimited moisture sensitivity).
Equivalent and substitute parts are identified based on matching or exceeding critical electrical parameters: off-state voltage rating, on-state current capacity, gate trigger characteristics, and package compatibility. Substitutes may vary in TRIAC type (Alternistor vs. Standard vs. Logic-Sensitive Gate), operating temperature range, and packaging format (Tube vs. Tape & Reel).

Substitute Part Grouping Explanation
Substitute parts are grouped into three categories based on electrical compatibility with the Q6016NH4TP:
Category 1: Direct Electrical Equivalents (16A, 600V) Parts matching the 16A on-state current and 600V off-state voltage rating. These provide equivalent current-handling capacity and voltage protection in the same package footprint.
Category 2: Reduced Current Capacity (10A–12A, 600V) Parts with lower on-state current ratings (10A or 12A) but maintaining 600V voltage rating. These are suitable for applications with lower current requirements but cannot be used in designs requiring the full 16A capacity.
Category 3: Alternative TRIAC Types Parts with different TRIAC classifications (Standard, Logic-Sensitive Gate) but matching voltage and current specifications. These offer different gate trigger characteristics and may require circuit evaluation.
Key substitution criteria:
- Voltage - Off State: Must be ≥ 600V
- Current - On State: Must be ≥ required application current
- Package / Case: Must be TO-263-3 or D2PAK compatible
- Mounting Type: Surface Mount
- Configuration: Single

Engineering Selection Recommendations
For 16A Applications (Direct Equivalents):
BT139B-600,118 (WeEn Semiconductors) provides electrical equivalence with 16A on-state current and 600V rating in the same D2PAK package. This Standard TRIAC type differs from the Alternistor classification but maintains gate trigger specifications within acceptable tolerance. RoHS3 compliance and MSL Level 1 rating match the original part. Tape & Reel packaging is available for high-volume production.
T1635-600G (STMicroelectronics) is an Alternistor-Snubberless variant matching the Q6016NH4TP classification with identical 16A current and 1.3V gate trigger voltage. This part maintains the same operating temperature range (-40°C to 125°C) and offers equivalent performance characteristics. RoHS3 compliance is confirmed.
For Reduced Current Applications (10A–12A):
T1235-600G, T1235-600G-TR, and T1235H-6G-TR (STMicroelectronics) are rated for 12A on-state current with 600V voltage rating. These Alternistor-Snubberless parts are suitable only for applications requiring ≤12A. The T1235H-6G-TR variant extends operating temperature to -40°C to 150°C and reduces gate trigger voltage to 1.0V.
T1050H-6G and T1050H-6G-TR (STMicroelectronics) are rated for 10A on-state current. These are suitable only for applications requiring ≤10A and offer extended temperature range (-40°C to 150°C) with 1.0V gate trigger voltage.
For Sensitive Gate Applications:
BT139B-600E,118 (WeEn Semiconductors) is a Logic-Sensitive Gate TRIAC with reduced gate trigger current (10mA vs. 35mA standard). This part maintains 16A on-state current and 600V rating but requires circuit evaluation for gate drive compatibility. RoHS compliance is confirmed.
Compliance Considerations:
All substitute parts are RoHS3 compliant or RoHS compliant. MSL Level 1 (unlimited) is maintained across all recommended substitutes. REACH status varies; WeEn Semiconductors parts show REACH Affected status, while STMicroelectronics parts show REACH Unaffected status.
Frequently Asked Questions (FAQ)
Q: Can I use a 12A-rated TRIAC (T1235 series) in place of the 16A Q6016NH4TP?
A: No. The 12A rating indicates maximum on-state current capacity. Using a 12A part in a 16A application will cause device failure or thermal stress. Current rating must meet or exceed application requirements.
Q: What is the difference between Alternistor and Standard TRIAC types?
A: Alternistor (Snubberless) TRIACs are optimized for operation without external snubber circuits, offering improved EMI performance. Standard TRIACs may require snubber networks in certain applications. Both types are electrically compatible when voltage and current ratings match, but circuit design may differ.
Q: Are BT139B-600,118 and BT139B-600E,118 interchangeable?
A: Both are 16A, 600V TRIACs in D2PAK packages, but they differ in gate trigger characteristics. The BT139B-600E,118 (Logic-Sensitive Gate) has lower gate trigger current (10mA vs. 35mA). Substitution requires verification that gate drive circuitry can accommodate the different trigger requirements.
Q: Does packaging format (Tube vs. Tape & Reel) affect electrical performance?
A: No. Tube and Tape & Reel packaging formats contain identical components. The difference is in handling and assembly convenience. Tube packaging is suitable for manual assembly; Tape & Reel is optimized for automated pick-and-place equipment.
Q: Can I use a part with extended temperature range (-40°C to 150°C) instead of the standard range (-40°C to 125°C)?
A: Yes. Extended temperature range parts (such as T1235H-6G-TR or T1250H-6G) are backward compatible with applications requiring the standard range. The extended range provides additional design margin for high-temperature environments.
Q: What does MSL Level 1 mean for moisture sensitivity?
A: MSL Level 1 indicates unlimited shelf life with no moisture sensitivity restrictions. The component does not require special dry-pack storage or baking procedures before soldering, simplifying inventory and assembly logistics.
Q: Are all substitute parts RoHS3 compliant?
A: Most substitute parts are RoHS3 compliant. BT139B-600E,118 is listed as RoHS compliant (not specifically RoHS3). Verify compliance status with your supply chain requirements before final selection.
