Key Parameters

Substitute Part Grouping Explanation

Substitution of the Q2016RH3 is determined by the following critical parameters:

• On-State Current Rating: 16 A maximum (RMS) — substitute must meet or exceed this specification
• Off-State Voltage Rating: 200 V minimum — substitute must support at least this voltage class
• Package Type: TO-220-3 Through Hole configuration — mechanical and thermal interface compatibility
• Gate Trigger Characteristics: Vgt and Igt parameters define gate drive requirements and circuit compatibility
• Operating Temperature Range: -40°C to 125°C — substitute must support this thermal envelope
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The identified substitute BTA216-600E,127 meets these criteria with a higher voltage rating (600 V), matching current capacity (16 A), compatible package (TO-220AB), and active product status. The elevated voltage rating provides design margin while maintaining electrical compatibility within the specified current and temperature parameters.

Engineering Selection Recommendations

The BTA216-600E,127 is the designated manufacturer-recommended substitute for the Q2016RH3. Selection is supported by:

• Current Capacity Match: Both devices rated at 16 A on-state current, ensuring load-handling equivalence
• Package Compatibility: Identical TO-220-3 Through Hole configuration permits direct mechanical and thermal interface replacement
• Voltage Margin: The 600 V off-state rating of the substitute exceeds the 200 V requirement of the original design, providing operational headroom
• Active Product Status: The substitute is in active production, ensuring long-term availability and supply chain stability
• Compliance Alignment: Both devices meet RoHS requirements, maintaining regulatory compliance in end-use applications
• Gate Drive Compatibility: Gate trigger voltage (1.5 V max) and current (10 mA max) specifications are within acceptable design tolerance ranges for existing gate drive circuits

Frequently Asked Questions (FAQ)

Q: Can the BTA216-600E,127 be used as a direct replacement for the Q2016RH3?

A: Yes. Both devices share identical on-state current ratings (16 A), compatible TO-220-3 packages, and overlapping operating temperature ranges. The substitute's higher voltage rating (600 V vs. 200 V) does not prevent substitution in 200 V applications.

Q: What is the difference between Alternistor and Logic - Sensitive Gate TRIAC types?

A: The Q2016RH3 is an Alternistor-type (snubberless), while the BTA216-600E,127 is a Logic-type with sensitive gate characteristics. Both are TRIAC devices suitable for AC switching; the gate sensitivity difference reflects design optimization but does not prevent functional substitution when gate drive circuits are compatible.

Q: Are the gate trigger specifications compatible?

A: Gate trigger voltage (Vgt) differs slightly: 1.3 V (Q2016RH3) vs. 1.5 V (BTA216-600E,127). Gate trigger current (Igt) is lower in the substitute (10 mA vs. 20 mA). These differences are within acceptable tolerance for standard gate drive circuits and do not prevent substitution.

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

A: No. A TRIAC rated for higher off-state voltage operates correctly in lower-voltage applications. The 600 V rating of the substitute provides design margin without degrading performance in 200 V circuits.

Q: Are both devices RoHS compliant?

A: Yes. The Q2016RH3 is ROHS3 Compliant, and the BTA216-600E,127 is RoHS Compliant. Both meet regulatory requirements for lead-free and restricted substance standards.

Q: What is the availability status of each device?

A: The Q2016RH3 is Obsolete with 1510 pieces in stock. The BTA216-600E,127 is Active with 974 pieces in stock, ensuring continued procurement availability.
