2SD2118TLQ Equivalent & Substitute Parts Reference

Part Overview

The 2SD2118TLQ from Rohm Semiconductor is an NPN bipolar junction transistor (BJT), rated for 20V, 5A, 150MHz, and 10W, supplied in a surface mount TO-252-3 (DPAK) package. It is not recommended for new designs due to its "Not For New Designs" product status. Sourcing alternatives is necessary for projects requiring current manufacturer support, active product status, or large batch manufacturing to ensure sustained availability and compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SD2118TLQ are identified strictly by matching electrical and mechanical parameters. These include: transistor type (NPN), maximum collector current (Ic), maximum collector-emitter voltage (Vce), collector cutoff current (ICBO), DC current gain (hFE), maximum power dissipation, transition frequency, operating temperature, mounting type, package, compliance (RoHS, REACH), ECCN, and HTSUS classification. All listed substitute parts must have values within the provided specifications of these key parameters and a compatible package.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 2SD2118TLQ and substitute part 2SD1805F-TL-E can be based on product status and compliance only. The 2SD2118TLQ is "Not For New Designs," while the 2SD1805F-TL-E is "Active." Both parts are ROHS3 compliant and REACH unaffected, with ECCN and HTSUS classifications matching. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both devices.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a valid substitute for the 2SD2118TLQ?
A: Substitutes must match transistor type (NPN), maximum collector current, maximum collector-emitter voltage, collector cutoff current, DC current gain, power dissipation, transition frequency, operating temperature, mounting type, package/case, RoHS and REACH status, moisture sensitivity, ECCN, and HTSUS.

Q: Is package compatibility assured between the 2SD2118TLQ and 2SD1805F-TL-E?
A: Both use TO-252-3, DPAK (2 Leads + Tab), SC-63, supporting direct package compatibility.

Q: How does product status affect substitute selection?
A: The main part, 2SD2118TLQ, is not for new designs. The substitute, 2SD1805F-TL-E, is active, making it suitable for new design and ongoing manufacturing requirements.

Q: Are there differences in environmental compliance between the two parts?
A: Both are ROHS3 compliant, REACH unaffected, with identical ECCN and HTSUS codes.

Q: Are technical characteristics such as collector current, voltage, and gain fully compatible?
A: All listed key parameters provided in the substitute match or exceed main part figures within explicit input specifications.
