Q2016NH6RP Equivalent & Substitute Parts

Part Overview

The Q2016NH6RP is a Snubberless TRIAC Alternistor manufactured by Littelfuse Inc., rated for 200 V off-state voltage and 16 A on-state current in a Surface Mount TO-263 (D2PAK) package. This component is classified as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The Snubberless design distinguishes this part from standard TRIAC configurations, affecting its application suitability in specific circuit topologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Q2016NH6RP is determined by the following critical parameters:

• Voltage Rating (Off State): The substitute must meet or exceed 200 V to maintain circuit protection margins
• Current Rating (On State): The substitute must support 16 A RMS minimum to handle load requirements
• Gate Trigger Characteristics: Vgt and Igt parameters must be compatible with existing gate drive circuitry
• Package Compatibility: Surface Mount TO-263 (D2PAK) package ensures mechanical and thermal interface compatibility
• Operating Temperature Range: Must support -40°C to 125°C junction temperature range

The identified substitute BTA216B-600B,118 meets these criteria with higher voltage rating (600 V), matching current capacity (16 A), and compatible package format. However, the BTA216B-600B,118 is classified as a Standard TRIAC rather than Snubberless Alternistor, representing a functional upgrade with enhanced voltage margin.

Parameter Comparison

Engineering Selection Recommendations

The BTA216B-600B,118 is an active product from WeEn Semiconductors with confirmed RoHS compliance and unlimited moisture sensitivity rating, providing supply chain continuity for the obsolete Q2016NH6RP. The substitute maintains identical on-state current capacity (16 A) and package format (D2PAK), with gate trigger parameters within acceptable tolerance for standard gate drive circuits.

The 600 V off-state voltage rating of the BTA216B-600B,118 exceeds the original 200 V specification, providing enhanced overvoltage margin. The transition from Snubberless Alternistor to Standard TRIAC configuration requires circuit-level evaluation to confirm compatibility with existing snubber network design, if present.

Both components share identical maximum junction temperature (125°C) and moisture sensitivity classification, ensuring thermal and environmental handling compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BTA216B-600B,118 directly replace the Q2016NH6RP in existing designs?

A: Mechanical and electrical interface compatibility is confirmed through matching package format (D2PAK), current rating (16 A), and gate trigger voltage range. The higher voltage rating (600 V vs. 200 V) provides additional margin. Verification of snubber network compatibility is required due to the change from Snubberless Alternistor to Standard TRIAC topology.

Q: What is the significance of the Snubberless Alternistor designation?

A: Snubberless Alternistor design eliminates the requirement for external RC snubber networks in certain AC switching applications. The BTA216B-600B,118 Standard TRIAC may require snubber circuit evaluation depending on load characteristics and switching frequency.

Q: Are the gate trigger parameters compatible?

A: The BTA216B-600B,118 exhibits Vgt of 1.5 V (vs. 1.3 V original) and Igt of 50 mA (vs. 80 mA original). These variations remain within typical gate drive circuit tolerance ranges for standard TRIAC applications.

Q: What is the impact of the 600 V rating on circuit design?

A: The elevated voltage rating provides increased transient overvoltage protection margin. No circuit redesign is required; the component operates safely at the original 200 V application voltage with enhanced reliability margin.

Q: Are both components RoHS compliant?

A: Yes. The Q2016NH6RP is RoHS3 Compliant, and the BTA216B-600B,118 is RoHS Compliant. Both meet environmental compliance requirements for current manufacturing standards.

Q: What is the package compatibility status?

A: Both components use Surface Mount TO-263 (D2PAK) packaging with identical pinout and thermal interface characteristics, ensuring PCB layout compatibility without modification.
