Equivalent & Substitute Parts Reference: IRF3708L

Part Overview

The IRF3708L from Infineon Technologies is an N-Channel MOSFET, classified within the Transistors, FETs, MOSFETs category. It features a 30V drain-to-source voltage, 62A continuous drain current, and is housed in a TO-262-3 Long Leads, I2PAK, TO-262AA package for through hole mounting. The part status is Obsolete, and it is RoHS non-compliant. When a product status is obsolete or is no longer compliant with RoHS, it becomes necessary to identify substitute parts to ensure continued manufacturability and regulatory compliance within designs.

Substitute Part Grouping Explanation

Substitution is determined strictly based on the following allowed electrical and mechanical parameters: FET type, technology, drain to source voltage (Vdss), continuous drain current (Id), drive voltage, Rds(on), gate threshold voltage (Vgs(th)), gate charge (Qg), maximum Vgs, input capacitance (Ciss), power dissipation, operating temperature range, mounting type, package/case, RoHS and REACH status, Moisture Sensitivity Level (MSL), and product status. Only parts meeting these specifications within the same package type and mounting configuration qualify as substitutes.

Engineering Selection Recommendations

Selection of substitutes is supported by both parts being in the obsolete status. For continued design and procurement, RoHS compliance may be required for newer projects; STI55NF03L provides ROHS3 compliance. Both IRF3708L and STI55NF03L feature identical mounting type and package/case options, and share common compliance: REACH unaffected, ECCN EAR99, HTSUS 8541.29.0095, and Moisture Sensitivity Level 1 (Unlimited). STI55NF03L matches the required product category and key specifications. Only parameters explicitly provided are evaluated.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting IRF3708L?
A1: Parameters considered are FET type, technology, drain-source voltage, continuous drain current, drive voltage range, Rds(on), gate threshold voltage, gate charge, Vgs(max), input capacitance, power dissipation, operating temperature, mounting type, package/case, RoHS and REACH status, MSL level, and part status.

Q2: Are there any differences in the package or mounting considerations between IRF3708L and its substitute STI55NF03L?
A2: Both use a through hole mounting type and share TO-262-3 Long Leads, I2PAK, TO-262AA package designations.

Q3: How does RoHS compliance impact substitute selection?
A3: IRF3708L is RoHS non-compliant, whereas STI55NF03L is ROHS3 compliant. RoHS compliance is necessary when meeting environmental regulations for new productions.

Q4: Is the electrical performance directly equivalent between IRF3708L and STI55NF03L?
A4: Substitution relies strictly on provided electrical parameters: Vdss, Id, Rds(on), Vgs(th), Qg, Ciss, power dissipation, and operating temperature. All compared specifications are documented above.

Q5: Are there any status limitations for using substitutes?
A5: Both components are listed as obsolete; substitute selection must be verified within the scope of available inventory and regulatory compliance requirements as listed.

Q6: Can STI55NF03L serve as a drop-in substitute for IRF3708L based on the provided data?
