Equivalent & Substitute Parts for L0107NERP

Part Overview

The L0107NERP is a Logic - Sensitive Gate TRIAC manufactured by Littelfuse Inc., rated for 800 V off-state voltage and 1 A on-state current in a Through Hole TO-92 package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L0107NERP is determined by strict equivalence across the following critical parameters:

• Triac Type: Logic - Sensitive Gate
• Voltage - Off State: 800 V
• Current - On State (It (RMS)) (Max): 1 A
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V
• Current - Gate Trigger (Igt) (Max): 5 mA maximum
• Current - Hold (Ih) (Max): 10 mA maximum
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Mounting Type: Through Hole
• Package / Case: TO-226-3, TO-92-3 (TO-226AA) Formed Leads

The substitute parts Z0103NA 2AL2 and Z0107NA 5AL2, both manufactured by STMicroelectronics, meet these electrical and mechanical requirements. Variations in non-rep surge current (Itsm) and gate trigger current (Igt) within the specified maximums do not disqualify substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both Z0103NA 2AL2 and Z0107NA 5AL2 are Active product status components manufactured by STMicroelectronics and maintain full RoHS3 and REACH compliance equivalent to the L0107NERP. Selection between the main part and substitutes is based on availability, packaging format (Cut Tape versus Tape & Reel), and inventory levels. Z0107NA 5AL2 provides parameter alignment identical to the L0107NERP across gate trigger current and hold current specifications. Z0103NA 2AL2 exhibits lower gate trigger current (3 mA) and hold current (7 mA) maximums, both within acceptable substitution margins for Logic - Sensitive Gate TRIAC applications at 800 V, 1 A ratings.

Frequently Asked Questions (FAQ)

Q: Can Z0103NA 2AL2 be used as a direct replacement for L0107NERP?

A: Z0103NA 2AL2 meets all critical electrical parameters: 800 V off-state voltage, 1 A on-state current, 1.3 V maximum gate trigger voltage, and -40°C to 125°C operating temperature. The lower gate trigger current (3 mA maximum) and hold current (7 mA maximum) are within acceptable substitution parameters for Logic - Sensitive Gate TRIAC applications. Package and mounting type are identical (Through Hole, TO-92-3).

Q: What is the difference between Z0107NA 5AL2 and Z0103NA 2AL2?

A: Both parts are STMicroelectronics Logic - Sensitive Gate TRIACs rated 800 V, 1 A. Z0107NA 5AL2 matches the L0107NERP gate trigger current (5 mA maximum) and hold current (10 mA maximum) exactly. Z0103NA 2AL2 has lower gate trigger current (3 mA maximum) and hold current (7 mA maximum). Both are electrically compatible substitutes; selection depends on application requirements and availability.

Q: Are packaging differences between these parts significant?

A: L0107NERP is supplied in Tape & Reel (TR) format. Z0103NA 2AL2 and Z0107NA 5AL2 are supplied in Cut Tape (CT) format. Both packaging formats contain identical TO-92-3 components with formed leads. Packaging format affects procurement and handling but does not alter electrical or mechanical compatibility.

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

A: Yes. L0107NERP, Z0103NA 2AL2, and Z0107NA 5AL2 are all RoHS3 compliant and REACH unaffected. All three carry ECCN EAR99 classification and HTSUS 8541.30.0080 tariff code.
