BCR 191F E6327 Equivalent & Substitute Parts

Part Overview

The BCR 191F E6327 is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Infineon Technologies, designed for surface mount applications in the SOT-723 package. This component integrates internal base resistors (R1 and R2 at 22 kOhms each) to simplify circuit design and reduce component count. The device is rated for 50 V collector-emitter breakdown voltage, 100 mA maximum collector current, and 250 mW power dissipation with a transition frequency of 200 MHz.

The BCR 191F E6327 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Engineering Selection Recommendations

Primary Substitutes (Full Electrical and Mechanical Compatibility):

PDTA124ET,215 (Nexperia USA Inc.) is the recommended primary substitute. This part maintains the 50 V collector-emitter breakdown voltage rating of the original BCR 191F E6327, ensuring full voltage compatibility. The PDTA124ET,215 is actively produced, ROHS3 compliant, and carries AEC-Q100 automotive qualification. The part is available in high volume (13,219 pcs in stock) and is supplied in Tape & Reel packaging. The improved saturation voltage (150 mV versus 300 mV) provides enhanced performance characteristics.

MUN2112T1G and NSVMUN2112T1G (onsemi) are secondary substitutes with identical electrical specifications to the BCR 191F E6327, including the 50 V breakdown voltage rating. Both parts are actively produced and ROHS3 compliant. MUN2112T1G offers the highest inventory availability (35,300 pcs in stock). NSVMUN2112T1G is the automotive-qualified variant (3,200 pcs in stock). Both parts are supplied in Tape & Reel packaging with SC-59 package designation.

Alternative Substitute (Reduced Voltage Rating):

DTA124ECAT116 (Rohm Semiconductor) is an alternative substitute with a reduced collector-emitter breakdown voltage rating of 20 V. This part is suitable only for applications where the operating voltage does not exceed 20 V. The DTA124ECAT116 is actively produced, ROHS3 compliant, and available in high volume (2,944 pcs in stock). This part is supplied in Cut Tape and Digi-Reel packaging with SST3 package designation.

Selection Criteria:

For applications requiring the full 50 V voltage rating, select PDTA124ET,215, MUN2112T1G, or NSVMUN2112T1G. For automotive applications, PDTA124ET,215 or NSVMUN2112T1G are qualified options. For general industrial applications with high volume requirements, MUN2112T1G provides maximum availability. For applications with voltage constraints below 20 V, DTA124ECAT116 is a viable option.

Frequently Asked Questions (FAQ)

Q: Can the DTA124ECAT116 be used as a direct replacement for the BCR 191F E6327?

A: The DTA124ECAT116 is electrically compatible with the BCR 191F E6327 in terms of collector current (100 mA), base resistor values (22 kOhms each), and pre-biased configuration. However, the DTA124ECAT116 has a maximum collector-emitter breakdown voltage of 20 V, compared to 50 V for the BCR 191F E6327. Direct substitution is only appropriate for applications where the operating voltage does not exceed 20 V.

Q: Are the substitute parts pin-compatible with the BCR 191F E6327?

A: The BCR 191F E6327 uses the SOT-723 package. The substitute parts (PDTA124ET,215, MUN2112T1G, NSVMUN2112T1G, and DTA124ECAT116) use TO-236-3, SC-59, or SOT-23-3 packages. While these packages have the same three-pin configuration and pin spacing, physical footprint differences exist. PCB layout modifications may be required to accommodate the different package dimensions.

Q: What is the difference between MUN2112T1G and NSVMUN2112T1G?

A: Both parts are manufactured by onsemi and have identical electrical specifications, including 50 V breakdown voltage, 100 mA collector current, and 22 kOhms base resistors. The NSVMUN2112T1G is the automotive-qualified variant with AEC-Q100 certification. Selection between these parts depends on application requirements and qualification standards.

Q: Are all substitute parts RoHS compliant?

A: Yes. PDTA124ET,215, MUN2112T1G, NSVMUN2112T1G, and DTA124ECAT116 are all ROHS3 compliant. The original BCR 191F E6327 RoHS status is not specified in the provided data.

Q: What is the impact of different saturation voltages on circuit performance?

A: The BCR 191F E6327 has a maximum saturation voltage of 300 mV at 500 µA base current and 10 mA collector current. The PDTA124ET,215 has a lower saturation voltage of 150 mV under the same conditions. Lower saturation voltage reduces power dissipation in saturated switching applications. The MUN2112T1G and NSVMUN2112T1G have saturation voltages of 250 mV at different bias conditions (300 µA base current). These differences are within acceptable ranges for most pre-biased transistor applications but should be evaluated for precision switching circuits.

Q: Can the BCR 191F E6327 be replaced with any of these substitutes in automotive applications?

A: For automotive applications, PDTA124ET,215 (AEC-Q100 qualified) or NSVMUN2112T1G (automotive-qualified variant) are appropriate selections. MUN2112T1G and DTA124ECAT116 do not carry automotive qualification in the provided data and should be evaluated against specific automotive standards if required.

Q: What is the moisture sensitivity level of the substitute parts?

A: All substitute parts (PDTA124ET,215, MUN2112T1G, NSVMUN2112T1G, and DTA124ECAT116) have a moisture sensitivity level of MSL 1 (Unlimited), matching the BCR 191F E6327. This classification indicates no moisture sensitivity restrictions for storage and handling.
