BCR 142F E6327 Equivalent & Substitute Parts

Part Overview

The BCR 142F E6327 is a pre-biased NPN bipolar junction transistor (BJT) manufactured by Infineon Technologies, designed for surface mount applications in the SOT-723 package. This component integrates internal base and emitter resistors (22 kΩ and 47 kΩ respectively) to simplify circuit design and reduce component count in switching and amplification applications.

The BCR 142F E6327 is classified as obsolete. Equivalent substitute parts are available from active product lines that maintain electrical and mechanical compatibility within the specified parameter ranges, enabling direct replacement in existing designs without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BCR 142F E6327 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Transistor type: NPN pre-biased configuration
• Collector-emitter breakdown voltage: 50 V (maximum)
• Base resistor value: 22 kΩ
• Emitter-base resistor value: 47 kΩ
• Vce saturation characteristics: 300 mV maximum at specified bias conditions
• Moisture sensitivity level: 1 (Unlimited)

Mechanical Compatibility Requirements:

• Mounting type: Surface mount
• Package classification: SOT-723 or equivalent footprint (TO-236-3, SC-59, SOT-23-3)

Operational Compatibility:

• Maximum collector current rating must equal or exceed 100 mA
• Transition frequency must support the intended switching or amplification bandwidth
• Power dissipation rating must equal or exceed 250 mW

Two substitute parts meet these criteria and are available from active product lines with current inventory status.

Parameter Comparison

Engineering Selection Recommendations

PDTC124XT,215 (Nexperia USA Inc.) is the primary substitute for BCR 142F E6327 applications. This part maintains full electrical equivalence with identical maximum collector current (100 mA) and power dissipation (250 mW) ratings. The PDTC124XT,215 is qualified to AEC-Q100 automotive standards and carries ROHS3 compliance, supporting both commercial and automotive-grade applications. Product status is active with established supply chain availability (1723 pcs in stock). The improved Vce saturation characteristic (150 mV vs. 300 mV) provides enhanced switching performance.

DTC124XKAT146 (Rohm Semiconductor) serves as an alternative substitute where collector current requirements do not exceed 50 mA. This part maintains electrical compatibility across all critical parameters including base and emitter resistor values, breakdown voltage, and saturation characteristics. The DTC124XKAT146 is active with higher inventory availability (15348 pcs in stock) and ROHS3 compliance. The reduced maximum collector current rating (50 mA) limits applicability to lower-current switching circuits. Transition frequency is elevated to 250 MHz, supporting higher-speed applications.

Both substitutes are surface mount components in SOT-23-3 package variants, compatible with existing PCB layouts designed for SOT-723 footprints through standard land pattern adaptation. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can BCR 142F E6327 be directly replaced with DTC124XKAT146?

A: Direct replacement is possible only in applications where collector current does not exceed 50 mA. The DTC124XKAT146 has a maximum collector current rating of 50 mA, compared to 100 mA for the BCR 142F E6327. If the circuit requires collector currents between 50 mA and 100 mA, use PDTC124XT,215 instead.

Q: What are the package compatibility considerations?

A: The BCR 142F E6327 uses SOT-723 packaging. Both substitute parts use TO-236-3/SC-59/SOT-23-3 packaging. These packages have different physical dimensions and land patterns. PCB layout modification is required for direct substitution. Verify footprint compatibility with your PCB design before implementation.

Q: Are the internal resistor values identical across all three parts?

A: Yes. All three parts (BCR 142F E6327, DTC124XKAT146, and PDTC124XT,215) have identical base resistor (22 kΩ) and emitter-base resistor (47 kΩ) values. This ensures circuit behavior remains consistent across substitution.

Q: Which substitute is recommended for new designs?

A: PDTC124XT,215 is recommended for new designs. It maintains full electrical equivalence with the original BCR 142F E6327, carries active product status with established supply chain, and includes AEC-Q100 automotive qualification and ROHS3 compliance.

Q: What is the significance of the improved Vce saturation in PDTC124XT,215?

A: The PDTC124XT,215 has a maximum Vce saturation of 150 mV compared to 300 mV in the BCR 142F E6327. Lower saturation voltage reduces power dissipation during switching transitions and improves switching speed, providing enhanced performance in high-frequency applications.

Q: Are moisture sensitivity requirements the same across all parts?

A: Yes. All three parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special precautions.

Q: What compliance certifications apply to the substitute parts?

A: Both PDTC124XT,215 and DTC124XKAT146 are ROHS3 compliant and REACH unaffected. PDTC124XT,215 additionally carries AEC-Q100 automotive qualification, enabling use in automotive-grade applications.
