L0107DTRP4 Equivalent & Substitute Parts

Part Overview

The L0107DTRP4 is a logic-sensitive gate TRIAC manufactured by Littelfuse Inc., rated for 400 V off-state voltage and 1 A on-state current in a surface mount SOT-223 package. This component is classified as obsolete, making direct substitutes necessary for new designs and production continuity. The L0107DTRP serves as the active equivalent, offering identical electrical specifications with improved availability.

Substitute Part Grouping Explanation

Substitution of the L0107DTRP4 with the L0107DTRP is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical parameters: triac type (logic-sensitive gate), voltage rating (400 V), current rating (1 A), gate trigger characteristics (Vgt 1.3 V max, Igt 5 mA max), hold current (10 mA max), surge current ratings (10A/12A), operating temperature range (-40°C to 125°C), and package configuration (SOT-223 / TO-261-4, TO-261AA). The primary distinction is product status: L0107DTRP4 is obsolete while L0107DTRP is active. Both maintain ROHS3 compliance and MSL Level 1 rating. The difference in packaging format (tube vs. tape & reel) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The L0107DTRP is the direct substitute for the L0107DTRP4. Selection is based on the following factors:

Electrical equivalence is complete across all specified parameters, including voltage rating, current capacity, gate trigger characteristics, and thermal operating range. Both parts maintain identical ROHS3 compliance and MSL Level 1 certification. The L0107DTRP offers the advantage of active product status with confirmed inventory availability (4400 pcs), whereas the L0107DTRP4 is obsolete. Packaging format differs only in distribution method (tape & reel vs. tube), which does not affect component performance or PCB assembly compatibility. For new designs and production continuity, the L0107DTRP is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can L0107DTRP replace L0107DTRP4 in existing designs? A: Yes. All electrical and mechanical parameters are identical. The parts are pin-compatible and functionally equivalent in the SOT-223 package configuration.

Q: What is the difference between L0107DTRP4 and L0107DTRP? A: The primary difference is product status. L0107DTRP4 is obsolete; L0107DTRP is active. Electrical specifications, package type, and compliance certifications are identical. Packaging format differs (tube vs. tape & reel).

Q: Are there any compliance or certification differences? A: No. Both parts maintain ROHS3 compliance and MSL Level 1 rating. ECCN and HTSUS classifications are identical.

Q: Does the tape & reel packaging of L0107DTRP affect assembly compatibility? A: No. Tape & reel packaging is a distribution format only. The component itself, its pinout, and electrical characteristics remain unchanged for PCB assembly.

Q: What are the critical parameters for substitution? A: Substitution is valid when the following parameters match: triac type (logic-sensitive gate), voltage rating (400 V), on-state current (1 A), gate trigger voltage (1.3 V max), gate trigger current (5 mA max), hold current (10 mA max), package type (SOT-223), and operating temperature range (-40°C to 125°C).
