Parameter Comparison

Engineering Selection Recommendations

RN2318(TE85L,F) - Toshiba Semiconductor

The RN2318(TE85L,F) is a direct functional equivalent with identical base and emitter-base resistor values (47 kOhms and 10 kOhms). This part maintains the same DC current gain specification and Vce saturation characteristics. The primary difference is package form factor (SC-70 / SOT-323 versus SOT-723) and reduced maximum power rating (100 mW versus 150 mW). Selection of this part requires PCB layout compatibility with SC-70 package dimensions. ROHS3 compliance status is equivalent to the main part.

DTA144TM3T5G - onsemi

Frequently Asked Questions (FAQ)

Q: Can RN2318(TE85L,F) replace RN2118MFV(TPL3) in all applications?

A: The RN2318(TE85L,F) is electrically equivalent with matching base and emitter-base resistor values. However, the SC-70 / SOT-323 package differs from the SOT-723 package of the main part. PCB layout and land pattern compatibility must be verified before substitution. The reduced maximum power rating (100 mW versus 150 mW) requires thermal analysis for high-current applications.

Q: What is the significance of the emitter-base resistor (R2) difference between parts?

A: The emitter-base resistor affects switching speed and turn-off characteristics. The main part and most substitutes specify 10 kOhms. The DTA144WM3T5G specifies 22 kOhms, which increases turn-off time. Applications requiring specific switching speed performance must account for this parameter difference.

Q: Are all substitute parts RoHS compliant?

A: The main part RN2118MFV(TPL3) is RoHS Compliant. All identified substitute parts are ROHS3 Compliant, which represents an updated RoHS standard. Both compliance levels are acceptable for RoHS-regulated applications.

Q: Which substitute part offers the best thermal performance?

A: The DTA144TM3T5G, DTA144WM3T5G, and NSBA144TF3T5G offer maximum power dissipation ratings of 260 mW, 260 mW, and 254 mW respectively, compared to 150 mW for the main part. These parts provide additional thermal margin for high-current or high-frequency switching applications.

Q: Can NSBA144TF3T5G be used as a direct footprint replacement?

A: The NSBA144TF3T5G uses SOT-1123 package, which differs from the SOT-723 package of the main part. Direct footprint replacement is not possible without PCB redesign. Package dimensions and pin assignments must be verified against design requirements.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel represent different supply formats for surface mount components. Cut Tape is supplied in individual strips, while Tape & Reel is supplied on continuous reels for automated assembly. Electrical and functional specifications are identical; packaging format selection depends on assembly process requirements and order quantities.

Q: Are all substitute parts suitable for high-frequency switching applications?

A: The DTA144TMT2L specifies transition frequency of 250 MHz, and the RN2318(TE85L,F) specifies 200 MHz. The main part RN2118MFV(TPL3) does not specify transition frequency. Applications requiring specific frequency performance must reference the transition frequency specification of the selected substitute part.

Q: What is MSL 1 (Unlimited) moisture sensitivity classification?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life under normal storage conditions without requiring special moisture control or baking procedures prior to assembly. All identified parts maintain this classification, ensuring equivalent handling requirements.
