Substitute Part Grouping Explanation
Substitute parts for the ACT102H-600D,118 are qualified based on the following critical parameters:
- Voltage - Off State: Must equal 600V
- Voltage - Gate Trigger (Vgt) (Max): Must not exceed 900mV to 1V range
- Current - Gate Trigger (Igt) (Max): Must not exceed 5mA to 10mA range
- Current - Hold (Ih) (Max): Must not exceed 20mA to 25mA range
- Configuration: Single TRIAC only
- Mounting Type: Surface Mount
- RoHS Compliance: Required
The ACS102-6T1-TR qualifies as a direct substitute with identical 600V rating, 200mA on-state current, and matching gate trigger specifications in an 8-SOIC package. The ACS108-6SN-TR qualifies as a functional substitute with higher on-state current capability (800mA) and compatible gate trigger parameters, though in a different SOT-223 package configuration.

Engineering Selection Recommendations
ACS102-6T1-TR is the primary substitute for direct replacement. It maintains identical electrical specifications (600V, 200mA, 900mV gate trigger) and package footprint (8-SOIC), with extended operating temperature range (-30°C to 125°C). Both parts are Active in product status and ROHS3 Compliant. STMicroelectronics ACS102 series offers higher inventory availability (12,600 units in stock versus 775 units for the ACT102H).
ACS108-6SN-TR is a functional substitute when higher on-state current capability (800mA) is acceptable within circuit design margins. This part operates in a different package (SOT-223) and requires PCB layout modification. Gate trigger specifications remain compatible (1V maximum, 10mA maximum). This option provides the highest inventory availability (17,254 units in stock).
Both substitute parts are Active products with full RoHS3 compliance and unlimited moisture sensitivity rating, meeting the compliance profile of the original ACT102H-600D,118.
Frequently Asked Questions (FAQ)
Q: Can ACS102-6T1-TR replace ACT102H-600D,118 without circuit modification?
A: Yes. The ACS102-6T1-TR is electrically and mechanically compatible. Both parts share identical 600V rating, 200mA on-state current, 900mV gate trigger voltage, and 8-SOIC package footprint. No circuit redesign is required.
Q: What is the difference between the Alternistor and Logic - Sensitive Gate TRIAC types?
A: Both types are functionally compatible for this application based on the provided electrical parameters. The Alternistor designation (ACS102-6T1-TR) indicates snubberless operation capability. The Logic - Sensitive Gate designation (ACT102H and ACS108-6SN-TR) indicates lower gate trigger current requirements. Selection depends on circuit snubber network design.
Q: Can ACS108-6SN-TR be used in place of ACT102H-600D,118?
A: ACS108-6SN-TR is functionally compatible for circuits where 800mA on-state current is acceptable. However, it requires PCB layout modification due to different package (SOT-223 versus 8-SOIC). Gate trigger specifications (1V, 10mA) remain within acceptable ranges for sensitive gate applications.
Q: Are all three parts RoHS compliant?
A: Yes. ACT102H-600D,118 is RoHS Compliant. Both ACS102-6T1-TR and ACS108-6SN-TR are ROHS3 Compliant, meeting current RoHS Directive requirements.
Q: What is the operating temperature range difference?
A: ACT102H-600D,118 specifies maximum junction temperature of 125°C. Both STMicroelectronics substitutes (ACS102-6T1-TR and ACS108-6SN-TR) specify operating range -30°C to 125°C, providing extended low-temperature performance.
Q: Which substitute offers the best inventory availability?
A: ACS108-6SN-TR has the highest inventory (17,254 units), followed by ACS102-6T1-TR (12,600 units). ACT102H-600D,118 has 775 units in stock.
