Substitute Part Grouping Explanation

Substitute parts for the L0107NE are classified based on the following substitution criteria:

MFR Recommended Substitutes maintain identical or superior electrical specifications across all critical parameters: off-state voltage (800 V), on-state current rating, gate trigger voltage, gate trigger current, hold current, and operating temperature range. These parts are mechanically compatible with the same Through Hole TO-92 package configuration.

Parametric Equivalents match the primary electrical specifications (800 V off-state voltage, 1 A on-state current, 1.3 V gate trigger voltage) and operate within the same temperature range, with minor variations in gate trigger current or hold current that remain within acceptable operational margins for the Logic - Sensitive Gate TRIAC category.

The following parameters determine substitution eligibility:

  • Voltage - Off State: 800 V (mandatory match)
  • Current - On State (It (RMS)) (Max): 1 A or higher
  • Triac Type: Logic - Sensitive Gate (mandatory match)
  • Mounting Type: Through Hole (mandatory match)
  • Package / Case: TO-92 or TO-92-3 compatible (mandatory match)
  • Operating Temperature Range: -40°C ~ 125°C or wider (mandatory match or exceed)

Engineering Selection Recommendations

Z0103NA 2AL2 (STMicroelectronics) is the primary MFR recommended substitute. This part maintains full electrical equivalence with the L0107NE across all critical parameters: 800 V off-state voltage, 1 A on-state current, 1.3 V gate trigger voltage, and -40°C ~ 125°C operating temperature range. The part is Active in product status and ROHS3 compliant. The packaging includes formed leads in TO-92-3 configuration, compatible with standard through-hole PCB layouts. This part is available in Cut Tape (CT) packaging.

Z0107NA 1AA2 (STMicroelectronics) is a parametric equivalent offering identical electrical specifications to the L0107NE. This part is Active in product status, ROHS3 compliant, and available in Bulk packaging. Gate trigger current and hold current specifications are equivalent to the primary part. The TO-92-3 package configuration ensures mechanical compatibility.

ACS108-8SA (STMicroelectronics) is listed as a substitute but carries Obsolete product status. While this part shares the 800 V off-state voltage and Through Hole TO-92 package configuration, the on-state current rating is reduced to 450 mA (versus 1 A for the L0107NE). This part is suitable only for applications where the lower current rating is acceptable. The operating temperature range is -30°C ~ 125°C, which is narrower than the L0107NE. ROHS3 compliance is maintained.

For new designs and applications requiring full electrical equivalence with Active product status, Z0103NA 2AL2 or Z0107NA 1AA2 are the recommended selections.

Frequently Asked Questions (FAQ)

Q: Can Z0103NA 2AL2 be used as a direct replacement for L0107NE?

A: Yes. Z0103NA 2AL2 maintains identical electrical specifications across all critical parameters: 800 V off-state voltage, 1 A on-state current, 1.3 V gate trigger voltage, and -40°C ~ 125°C operating temperature range. The Through Hole TO-92-3 package is mechanically compatible with standard PCB layouts designed for the L0107NE.

Q: What is the difference between Z0103NA 2AL2 and Z0107NA 1AA2?

A: Both parts are parametric equivalents with identical primary electrical specifications. Z0103NA 2AL2 is available in Cut Tape (CT) packaging, while Z0107NA 1AA2 is available in Bulk packaging. Gate trigger current for Z0103NA 2AL2 is 3 mA (versus 5 mA for Z0107NA 1AA2), and hold current is 7 mA (versus 10 mA). These variations remain within acceptable operational margins for Logic - Sensitive Gate TRIAC applications.

Q: Why is ACS108-8SA listed as a substitute if it has lower current rating?

A: ACS108-8SA shares the 800 V off-state voltage and Through Hole TO-92 package configuration with the L0107NE. However, the on-state current rating is 450 mA, which is 55% lower than the L0107NE's 1 A rating. This part is suitable only for applications where the reduced current capacity is acceptable. The product is Obsolete, making it unsuitable for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. L0107NE and all listed substitute parts (Z0103NA 2AL2, Z0107NA 1AA2, and ACS108-8SA) are ROHS3 compliant.

Q: What is the operating temperature difference between L0107NE and ACS108-8SA?

A: L0107NE operates from -40°C to 125°C (TJ), while ACS108-8SA operates from -30°C to 125°C (TJ). The L0107NE provides 10°C wider low-temperature operation. For applications requiring operation below -30°C, ACS108-8SA is not suitable.

Q: Are the TO-92 and TO-92-3 packages interchangeable?

A: Both TO-92 and TO-92-3 are Through Hole packages with compatible pin configurations and mechanical footprints. Parts specified as TO-92-3 with formed leads are suitable for standard through-hole PCB layouts designed for TO-92 components. Verify PCB footprint compatibility before assembly.
