Obsolete Status - Not Recommended:

BC850CE6327HTSA1 (Infineon Technologies) is classified as Obsolete. While electrical specifications match the 2SC1623-L6-TP with 250 MHz transition frequency and 330 mW power rating, the obsolete status indicates discontinued production and limited future availability. This part should not be selected for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can BC847CLT1G directly replace 2SC1623-L6-TP in all applications?

A: BC847CLT1G meets all primary matching criteria: NPN type, SOT-23-3 package, 100 mA collector current, and full temperature range operation. The 45 V breakdown voltage is lower than the 50 V specification of the 2SC1623-L6-TP. Direct replacement is suitable for applications operating below 45 V. For circuits requiring 50 V operation, NSVMSD601-RT1G maintains the original 50 V specification.

Q: What is the difference between BC850BLT1G and BC850CLT1G?

A: Both parts are manufactured by onsemi with identical electrical specifications: 45 V breakdown voltage, 100 mA collector current, 225 mW power rating, and 100 MHz transition frequency. The primary difference is packaging: BC850BLT1G is supplied in Tape & Reel format, while BC850CLT1G is supplied in Cut Tape & Digi-Reel format. BC850CLT1G has significantly higher inventory availability (254,300 pieces versus 65,200 pieces).

Q: Why is BC848BT116 listed as a substitute if it has only 30 V breakdown voltage?

A: BC848BT116 meets all primary matching criteria for package, current rating, and mounting type. The 30 V breakdown voltage is lower than the 2SC1623-L6-TP specification. This part is suitable for applications operating at 30 V or below. For circuits requiring higher voltage operation, select BC847A RFG, BC847CLT1G, BC847CLT3G, BC850B,215, BC850BLT1G, BC850CLT1G, or BCW72,215, which all provide 45 V or higher breakdown voltage.

Q: Are automotive-grade substitutes available?

A: Yes. BC850B,215 and BCW72,215 are both automotive-grade parts with AEC-Q101 qualification. These parts are suitable for automotive and industrial applications requiring qualification documentation and enhanced reliability screening.

Q: What is the significance of the transition frequency difference between 2SC1623-L6-TP (250 MHz) and BC847CLT1G (100 MHz)?

A: Transition frequency (fT) indicates the frequency at which current gain drops to unity. The 2SC1623-L6-TP operates at 250 MHz while BC847CLT1G operates at 100 MHz. For general-purpose switching and low-frequency amplification applications, 100 MHz transition frequency is sufficient. For high-frequency applications approaching or exceeding 100 MHz, BC848BT116 (200 MHz) or BC850CE6327HTSA1 (250 MHz) provide closer frequency matching. BC850CE6327HTSA1 is obsolete and not recommended for new designs.

Q: Can I use BC850CLT1G in place of 2SC1623-L6-TP for a new product design?

A: BC850CLT1G is suitable for new product designs. The part is Active status with full RoHS3 compliance, unlimited moisture sensitivity rating, and high inventory availability. The 45 V breakdown voltage is lower than the 2SC1623-L6-TP specification; verify that your circuit operates below 45 V. The 100 MHz transition frequency is lower than the original part; confirm that your application does not require frequencies above 100 MHz. If 50 V operation or 250 MHz transition frequency is required, select NSVMSD601-RT1G instead.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel, Tape & Reel (TR), and specialized packages such as SST3 and PG-SOT23. All parts maintain SOT-23-3 or equivalent surface mount package compatibility. Select packaging based on production volume and assembly requirements. For high-volume production, Tape & Reel format is standard. For lower volumes or prototype work, Cut Tape & Digi-Reel format is appropriate.

Q: Is NSVMSD601-RT1G the only upgrade substitute?

A: NSVMSD601-RT1G is the only part listed in the upgrade category, maintaining the 50 V breakdown voltage specification. All other substitutes are classified as similar parts with 45 V or lower breakdown voltage. If 50 V operation is mandatory, NSVMSD601-RT1G is the appropriate selection.
