Q8012NH2RP Equivalent & Substitute Parts

Part Overview

The Q8012NH2RP is a Snubberless Alternistor TRIAC manufactured by Littelfuse Inc., rated for 800 V off-state voltage and 12 A on-state current in a surface mount D2PAK package. This component is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory availability changes, or when functionally compatible devices from different manufacturers meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the Q8012NH2RP are identified based on the following critical parameters that determine functional compatibility:

Voltage - Off State: 800 V (minimum requirement)
Current - On State (It (RMS)): 12 A or greater
Package / Case: TO-263-3, D2PAK (2 Leads + Tab)
Mounting Type: Surface Mount
Configuration: Single
Operating Temperature Range: -40°C ~ 125°C or higher

The T1210-800G-TR from STMicroelectronics meets all core electrical and mechanical requirements with identical voltage and current ratings, matching gate trigger specifications, and equivalent thermal operating range. The BTA316B-800E,118 from WeEn Semiconductors provides a higher current rating (16 A) while maintaining the same 800 V voltage class and D2PAK package, making it suitable for applications requiring additional current margin.

Engineering Selection Recommendations

The T1210-800G-TR provides direct electrical and mechanical equivalence to the Q8012NH2RP with identical current and voltage ratings. Both components maintain RoHS3 compliance and equivalent thermal specifications, making this substitute suitable for one-to-one replacement in existing designs without circuit modification.

The BTA316B-800E,118 offers increased current capacity (16 A versus 12 A) while maintaining the same voltage class and package footprint. This part is appropriate for applications where additional current margin is beneficial or where design requirements have evolved to demand higher current handling. The gate trigger voltage specification (1.5 V maximum) remains within acceptable operating parameters for most gate drive circuits designed for the original 1.3 V specification. RoHS compliance status differs (RoHS versus RoHS3), which may require verification against specific procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the T1210-800G-TR replace the Q8012NH2RP in existing PCB designs?

A: Yes. The T1210-800G-TR is mechanically and electrically compatible with identical D2PAK package dimensions, pin configuration, and electrical ratings (800 V, 12 A). No circuit modifications or PCB layout changes are required.

Q: What is the primary difference between the Q8012NH2RP and BTA316B-800E,118?

A: The BTA316B-800E,118 provides higher on-state current capacity (16 A versus 12 A) while maintaining the same 800 V voltage rating and D2PAK package. Gate trigger voltage is specified at 1.5 V maximum compared to 1.3 V for the Q8012NH2RP. Both operate across the same temperature range (-40°C to 125°C).

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-263-3 D2PAK package with identical pin configuration (2 leads plus tab), enabling direct PCB footprint compatibility.

Q: What compliance certifications apply to these parts?

A: The Q8012NH2RP and T1210-800G-TR are RoHS3 compliant. The BTA316B-800E,118 is RoHS compliant. All three parts are REACH unaffected and classified under ECCN EAR99.

Q: Does moisture sensitivity affect storage or handling?

A: All three parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Which substitute should be selected for new designs?

A: Selection depends on current requirements. For applications requiring 12 A or less, either the T1210-800G-TR or Q8012NH2RP is appropriate. For applications benefiting from higher current capacity, the BTA316B-800E,118 is suitable, provided the 1.5 V gate trigger voltage specification is compatible with the gate drive circuit design.
