Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Q6012NH2RP are qualified based on the following electrical and mechanical parameters:

• Voltage - Off State: 600 V (exact match required)
• Current - On State (It (RMS)) (Max): 12 A (exact match required)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (exact match required)
• Current - Gate Trigger (Igt) (Max): 10 mA (exact match required)
• Current - Hold (Ih) (Max): 15 mA (exact match required)
• Operating Temperature Range: -40°C to 125°C (TJ) (exact match required)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Triac Type: Alternistor - Snubberless (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The STMicroelectronics T1210-6G and T1210-6G-TR meet all electrical and mechanical substitution criteria. The primary distinction between substitute parts is packaging format: T1210-6G is supplied in Tube packaging, while T1210-6G-TR is supplied in Tape & Reel (TR) format, matching the original Q6012NH2RP packaging specification.

Parameter Comparison

Engineering Selection Recommendations

Both T1210-6G and T1210-6G-TR are active-status components with ROHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory and environmental requirements of the Q6012NH2RP.

For applications requiring Tape & Reel packaging to match original procurement specifications and automated assembly processes, T1210-6G-TR is the direct equivalent.

For applications where packaging format flexibility is acceptable, T1210-6G in Tube format provides equivalent electrical performance with alternative supply logistics.

All three parts share identical electrical ratings for voltage, current, gate trigger characteristics, and operating temperature range, ensuring functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can T1210-6G and T1210-6G-TR be used interchangeably with Q6012NH2RP?

A: Yes. Both STMicroelectronics parts meet all electrical and mechanical substitution criteria, including voltage rating (600 V), on-state current (12 A), gate trigger voltage (1.3 V maximum), and operating temperature range (-40°C to 125°C). The primary difference is packaging format: T1210-6G-TR matches the original Tape & Reel format, while T1210-6G uses Tube packaging.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: off-state voltage (600 V), on-state current rating (12 A), gate trigger voltage (1.3 V maximum), gate trigger current (10 mA maximum), hold current (15 mA maximum), operating temperature range (-40°C to 125°C), package type (TO-263-3, D2PAK), and triac type (Alternistor - Snubberless).

Q: Are there differences in surge current ratings between the main part and substitutes?

A: The Q6012NH2RP specifies non-repetitive surge current of 110A and 120A for 50 and 60 Hz respectively. The T1210-6G and T1210-6G-TR specify 120A and 126A for the same conditions. These differences do not affect substitution eligibility, as surge ratings represent maximum transient capability and the substitute parts exceed the original specifications.

Q: Which substitute part should be selected for automated assembly?

A: T1210-6G-TR is recommended for automated assembly processes, as it is supplied in Tape & Reel format, matching the original Q6012NH2RP packaging specification and standard pick-and-place equipment compatibility.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. Q6012NH2RP, T1210-6G, and T1210-6G-TR are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.
