Q2016RH4 Equivalent & Substitute Parts

Part Overview

The Q2016RH4 is a Littelfuse TRIAC Alternistor rated for 200 V off-state voltage and 16 A on-state current in a Through Hole TO-220 package. This component is classified as Obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The Alternistor configuration provides snubberless operation, distinguishing it from standard TRIAC designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Q2016RH4 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 to handle the same load conditions
• Package Type: TO-220-3 Through Hole configuration ensures mechanical and thermal compatibility
• Gate Trigger Characteristics: Vgt and Igt parameters must be compatible with existing gate drive circuits
• Temperature Range: Operating range must encompass -40°C to 125°C for thermal compatibility
• Regulatory Compliance: RoHS compliance status ensures material and environmental standards alignment

The BTA216-600F,127 qualifies as a substitute based on matching current rating (16 A), compatible package (TO-220-3), overlapping temperature range, and regulatory compliance. The higher voltage rating (600 V vs. 200 V) provides additional circuit protection margin and is acceptable for applications designed for 200 V operation.

Parameter Comparison

Engineering Selection Recommendations

The BTA216-600F,127 is an active product from WeEn Semiconductors and serves as a direct functional substitute for the obsolete Q2016RH4. Both components share identical on-state current ratings (16 A) and compatible TO-220-3 Through Hole packaging. The substitute's higher voltage rating (600 V) does not compromise circuit operation in 200 V applications and provides enhanced overvoltage protection.

The substitute maintains RoHS compliance, satisfying regulatory requirements equivalent to the original part. The gate trigger voltage specification (1.5 V maximum) is marginally higher than the original (1.3 V maximum), requiring verification that existing gate drive circuits can reliably trigger the substitute across the specified temperature and load ranges.

The substitute's lower gate trigger current (25 mA vs. 35 mA) and hold current (30 mA vs. 50 mA) may reduce gate drive circuit loading, potentially improving overall system efficiency.

Frequently Asked Questions (FAQ)

Q: Can the BTA216-600F,127 directly replace the Q2016RH4 in existing designs?

A: The BTA216-600F,127 matches the critical electrical parameters (16 A on-state current, TO-220-3 package, compatible temperature range) and is mechanically interchangeable. The higher voltage rating (600 V vs. 200 V) is acceptable for 200 V circuit applications. Gate drive circuit compatibility should be confirmed, as the gate trigger voltage specification differs slightly (1.5 V vs. 1.3 V maximum).

Q: What is the difference between Alternistor and Standard TRIAC types?

A: The Q2016RH4 is an Alternistor (snubberless) configuration, while the BTA216-600F,127 is a Standard TRIAC. Both are functionally equivalent for switching applications. The Alternistor designation indicates optimized performance without external snubber networks, though this distinction does not prevent substitution in standard TRIAC applications.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. A 600 V rated TRIAC operating in a 200 V circuit provides additional safety margin against transient overvoltages. The on-state current rating (16 A) and thermal characteristics remain the primary performance determinants.

Q: Are both parts RoHS compliant?

A: Yes. The Q2016RH4 is ROHS3 Compliant, and the BTA216-600F,127 is RoHS Compliant. Both meet current environmental and material standards.

Q: What packaging formats are available for the substitute?

A: The BTA216-600F,127 is supplied in Tube packaging. The Q2016RH4 packaging format is not specified in the provided data. Both components use the TO-220-3 Through Hole package case, ensuring mechanical compatibility.
