Q8010L4TP Equivalent & Substitute Parts

Part Overview

The Q8010L4TP is a standard TRIAC manufactured by Littelfuse Inc., rated for 800V off-state voltage and 10A on-state current in a TO-220-3 isolated tab package. This component is actively produced and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Q8010L4TP is determined by the following criteria:

Mandatory Matching Parameters:

• Voltage - Off State: 800V (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: TO-220-3 Isolated Tab (exact match required)
• Configuration: Single (exact match required)

Allowable Parameter Ranges for Substitution:

• Current - On State (It (RMS)) (Max): Must be ≥10A
• Voltage - Gate Trigger (Vgt) (Max): Must be ≤1.3V or higher (within component design limits)
• Current - Gate Trigger (Igt) (Max): Must be ≤25mA or higher (within component design limits)
• Current - Hold (Ih) (Max): Must be ≤35mA or higher (within component design limits)
• Operating Temperature: Must support minimum -40°C to 125°C range

The BTA416Y-800C,127 meets all mandatory matching criteria and operates within allowable parameter ranges, qualifying it as a valid substitute.

Parameter Comparison

Engineering Selection Recommendations

The BTA416Y-800C,127 is a qualified substitute for the Q8010L4TP based on the following factors:

Compliance & Certification Alignment: Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS classifications, and share MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory and supply chain compatibility.

Electrical Performance: The substitute part maintains the critical 800V off-state voltage specification and through-hole TO-220-3 isolated tab package configuration. The BTA416Y-800C,127 is rated for higher on-state current (16A vs. 10A), higher gate trigger current (35mA vs. 25mA), and higher non-repetitive surge current, providing enhanced performance margins within the same voltage class.

Thermal Capability: The substitute supports an extended operating temperature range up to 150°C, compared to the main part's 125°C maximum, offering improved thermal headroom for demanding applications.

Inventory & Availability: The BTA416Y-800C,127 maintains higher stock levels (6723 pcs vs. 664 pcs), supporting consistent supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the BTA416Y-800C,127 be used as a direct replacement for the Q8010L4TP?

A: Yes, the BTA416Y-800C,127 qualifies as a direct substitute. Both parts share identical off-state voltage (800V), mounting type (through hole), and package configuration (TO-220-3 isolated tab). The substitute is rated for higher current capacity and gate trigger specifications, making it functionally compatible for applications designed around the Q8010L4TP.

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

A: The primary differences are manufacturer (Littelfuse vs. WeEn Semiconductors), on-state current rating (10A vs. 16A), gate trigger voltage (1.3V vs. 1.5V), non-repetitive surge current (100A/120A vs. 160A/176A), and maximum operating temperature (125°C vs. 150°C). All differences favor the substitute part with higher ratings.

Q: Are there any package or pinout differences?

A: No. Both parts use the TO-220-3 isolated tab package with identical mechanical and electrical pinout configurations, ensuring direct PCB compatibility without layout modifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, share the same HTSUS code (8541.30.0080), and have MSL Level 1 (Unlimited) ratings, ensuring equivalent regulatory and supply chain status.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring the specified 10A on-state current with 1.3V gate trigger voltage, the Q8010L4TP is the primary choice. For applications benefiting from higher current capacity, lower gate trigger requirements, or extended temperature operation, the BTA416Y-800C,127 is the preferred option. Both are active products with confirmed availability.
