Q6012RH2TP TRIAC Equivalent & Substitute Parts

Part Overview

The Q6012RH2TP is an Alternistor-type TRIAC manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 12 A on-state current in a Through Hole TO-220AB package. This snubberless design is actively produced and RoHS3 compliant. Substitute parts are identified based on matching electrical ratings and mechanical compatibility within the thyristor category, enabling direct replacement in applications where the specified parameters align.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Q6012RH2TP is determined by the following criteria:

Primary Matching Parameters:

• Voltage - Off State: 600 V (exact match required)
• Package / Case: TO-220-3 (mechanical compatibility)
• Mounting Type: Through Hole (installation compatibility)
• Configuration: Single (functional equivalence)

Secondary Compatibility Parameters:

• Current - On State (It (RMS)) (Max): Equal to or greater than 12 A
• Voltage - Gate Trigger (Vgt) (Max): Equal to or less than 1.3 V
• Current - Gate Trigger (Igt) (Max): Equal to or less than 10 mA
• Current - Hold (Ih) (Max): Equal to or less than 15 mA

Product Status Requirement:

• Active status ensures ongoing availability and support

The identified substitutes meet these criteria with variations in TRIAC type (Alternistor vs. Logic-Sensitive Gate vs. Standard) and current surge ratings, which do not prevent functional substitution when electrical parameters remain within acceptable ranges.

Parameter Comparison

Engineering Selection Recommendations

BTB12-600SWRG (STMicroelectronics): This substitute provides exact current and voltage-gate-trigger matching with the Q6012RH2TP. Both devices maintain identical on-state current (12 A) and gate trigger voltage (1.3 V) specifications. The BTB12-600SWRG is Logic-Sensitive Gate type versus the Alternistor type of the original part; however, both are single-configuration TRIACs in TO-220-3 packages with equivalent electrical performance within the specified parameters. RoHS3 compliance and active product status support direct substitution.

BTA316-600ET,127 (WeEn Semiconductors): This part exceeds the on-state current rating (16 A vs. 12 A) and operates at higher maximum temperature (150°C vs. 125°C). The gate trigger voltage is slightly elevated (1.5 V vs. 1.3 V), remaining within acceptable substitution margins. The Logic-Sensitive Gate configuration and TO-220-3 package provide mechanical compatibility. RoHS3 compliance is confirmed; however, REACH status is listed as affected, requiring verification for applications subject to REACH regulations.

BTA316-600ET/DGQ (WeEn Semiconductors): This Standard-type TRIAC offers the lowest gate trigger voltage (1 V) among substitutes, with 16 A on-state current and 150°C maximum operating temperature. The TO-220-3 package and RoHS3 compliance ensure compatibility. This option provides the highest current margin and lowest gate trigger threshold, suitable for applications requiring enhanced gate sensitivity or higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can the BTB12-600SWRG replace the Q6012RH2TP in all applications?

A: The BTB12-600SWRG matches the Q6012RH2TP in voltage (600 V), on-state current (12 A), gate trigger voltage (1.3 V), and operating temperature range (-40°C ~ 125°C). Both are single-configuration TRIACs in TO-220-3 packages. Substitution is valid where these electrical parameters define the application requirement. TRIAC type differences (Alternistor vs. Logic-Sensitive Gate) do not prevent functional replacement when electrical specifications align.

Q: What is the difference between the BTA316 variants?

A: BTA316-600ET,127 is Logic-Sensitive Gate type with 1.5 V maximum gate trigger voltage. BTA316-600ET/DGQ is Standard type with 1 V maximum gate trigger voltage. Both share 600 V off-state voltage, 16 A on-state current, and 150°C maximum operating temperature. The Standard variant (BTA316-600ET/DGQ) requires lower gate trigger current, making it suitable for gate-drive-limited applications.

Q: Are the BTA316 parts suitable substitutes despite higher current ratings?

A: Yes. The BTA316 series (both variants) exceed the 12 A on-state current requirement with 16 A ratings. Higher current capacity does not prevent substitution; the device will operate within the application's actual current demand. The 600 V off-state voltage, TO-220-3 package, and single-configuration design ensure mechanical and electrical compatibility.

Q: What compliance considerations apply to these substitutes?

A: All four parts (Q6012RH2TP, BTB12-600SWRG, BTA316-600ET,127, and BTA316-600ET/DGQ) are RoHS3 compliant. The BTA316-600ET,127 lists REACH status as affected; applications subject to REACH regulations require verification of this part's compliance documentation. The Q6012RH2TP, BTB12-600SWRG, and BTA316-600ET/DGQ show REACH unaffected or no restriction noted.

Q: Does package designation TO-220 versus TO-220AB affect substitution?

A: Both designations refer to the same TO-220-3 package form factor with Through Hole mounting. The supplier device package notation (TO-220 vs. TO-220AB) reflects manufacturer labeling conventions and does not affect mechanical or electrical compatibility. All parts in this comparison are mechanically interchangeable in TO-220-3 footprints.

Q: Can I use these substitutes in applications with temperature extremes?

A: The Q6012RH2TP and BTB12-600SWRG operate from -40°C to 125°C. The BTA316 variants extend to 150°C maximum. For applications requiring operation above 125°C, the BTA316 series is required. For applications within -40°C to 125°C, all four parts are suitable.
