Engineering Selection Recommendations

Manufacturer Recommended Substitutes:

ACS108-8SN-TR and ACS108-8TN-TR (STMicroelectronics) are designated as manufacturer recommended alternatives. Both maintain 800 V off-state voltage and Logic - Sensitive Gate configuration. ACS108-8TN-TR matches the operating temperature range of -40°C to 125°C and gate trigger current of 5 mA. ACS108-8SN-TR operates from -30°C, which is acceptable for applications not requiring the full -40°C lower limit. Both are ROHS3 compliant and Active in product status. The on-state current rating of 800 mA is lower than the L0107NTRP's 1 A; applications requiring the full 1 A capacity must account for this derating.

Parametric Equivalent Substitutes:

Z0107NN 5AA4 (STMicroelectronics) provides direct parametric equivalence with matching 1 A on-state current, 1.3 V gate trigger voltage, 5 mA gate trigger current, and -40°C to 125°C operating range in SOT-223 package. This part is ROHS3 compliant and Active.

Z0103NN5AA4 (STMicroelectronics) matches the 1 A on-state current and 1.3 V gate trigger voltage in SOT-223 package with -40°C to 125°C operating range. Gate trigger current is 3 mA, which is lower than the L0107NTRP specification. This part is ROHS3 compliant and Active.

Package Consideration:

Z0103NN0,135 and Z0109NN0,135 (WeEn Semiconductors) use SC-73 package instead of SOT-223. These parts match electrical specifications but require PCB layout and footprint modifications. Both are Active in product status. Z0103NN0,135 is ROHS3 compliant. Z0109NN0,135 is RoHS compliant but does not specify ROHS3 status. Operating temperature for both is specified as 125°C maximum without a stated minimum, which differs from the L0107NTRP's -40°C minimum.

Frequently Asked Questions (FAQ)

Q: Can ACS108-8SN-TR replace L0107NTRP in all applications?

A: ACS108-8SN-TR is electrically compatible for 800 V, Logic - Sensitive Gate TRIAC applications. The on-state current rating is 800 mA versus the L0107NTRP's 1 A. Applications requiring the full 1 A capacity must account for this lower rating. Operating temperature minimum is -30°C instead of -40°C; applications operating below -30°C require alternative selection.

Q: What is the difference between SOT-223 and SC-73 packages?

A: SOT-223 and SC-73 are different surface mount package formats with different footprints and pin configurations. Direct substitution between these packages requires PCB redesign and layout modification. Z0103NN0,135 and Z0109NN0,135 use SC-73 package and are not pin-compatible drop-in replacements for the L0107NTRP SOT-223 package.

Q: Are all substitute parts RoHS3 compliant?

A: ACS108-8SN-TR, ACS108-8TN-TR, Z0103NN0,135, Z0103NN5AA4, and Z0107NN 5AA4 are ROHS3 compliant. Z0109NN0,135 is RoHS compliant but does not specify ROHS3 status. Verify compliance requirements for your application before selection.

Q: Which substitute part has the lowest gate trigger current?

A: Z0103NN0,135 and Z0103NN5AA4 both specify 3 mA maximum gate trigger current, which is lower than the L0107NTRP's 5 mA specification. This may affect gate drive circuit design and should be evaluated for your specific application requirements.

Q: Can I use Z0109NN0,135 as a direct replacement?

A: Z0109NN0,135 matches the 800 V voltage and 1 A on-state current in SC-73 package. Operating temperature is specified as 125°C maximum without a stated minimum, differing from the L0107NTRP's -40°C to 125°C range. Package format requires PCB redesign. This part is suitable only for applications not requiring the full temperature range and where PCB layout modification is acceptable.

Q: What is the inventory status of substitute parts?

A: ACS108-8SN-TR has 100,400 pcs in stock. ACS108-8TN-TR has 7,075 pcs. Z0107NN 5AA4 has 16,121 pcs. Z0103NN5AA4 has 7,601 pcs. Z0103NN0,135 has 3,346 pcs. Z0109NN0,135 has 2,579 pcs. Availability should be confirmed for production requirements.
