Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly by alignment of essential electrical and mechanical characteristics: NPN transistor type, collector-emitter voltage rating, collector current rating, package compatibility (TO-252-3, DPAK), mounting type (surface mount), and RoHS compliance. These key parameters determine suitability as direct replacements without introducing fit or operational concerns.

Parameter Comparison

Engineering Selection Recommendations

The 2SD2118TLR is marked “Not For New Designs”. Substitute parts 2SD1805F-TL-E and MJD200RLG are listed as “Active” and possess ROHS3 compliance, unlimited moisture sensitivity level, and REACH Unaffected status, ensuring compatibility with regulated and high-volume production environments strictly in accordance with supplied certifications and compliance information.

Frequently Asked Questions (FAQ)

Q1: What are the primary electrical parameters for direct substitution in bipolar NPN transistors?
A1: Transistor type, collector-emitter breakdown voltage, collector current, and package type are mandatory matching parameters.

Q2: How do I verify package compatibility for surface mount replacements?
A2: All listed models use TO-252-3, DPAK (2 Leads + Tab), SC-63; matching ensures physical and reflow compatibility.

Q3: Are substitute parts compliant with RoHS and REACH standards?
A3: All substitute parts are ROHS3 Compliant and REACH Unaffected per provided documentation.

Q4: Why is current gain (hFE) minimum significant in selection?
A4: Minimum hFE defines drive and bias requirements. Equivalent substitution must maintain compatibility at stated test points.

Q5: Why are substitutes recommended over the original 2SD2118TLR?
A5: The 2SD2118TLR is “Not For New Designs”. Substitutes assure ongoing availability, regulatory compliance, and active status.

Q6: Are there differences in maximum power dissipation or transition frequency among substitutes?
A6: Differences exist. Substitutes have lower maximum power and transition frequency per provided parameters. These must be determined to be suitable based on application requirements within the provided ratings.

Q7: Will the surface mount process be affected by choosing a listed substitute?
A7: All substitutes retain surface mount compatibility with TO-252-3, DPAK package, ensuring unchanged assembly process.
