BCR 179F E6327 Equivalent & Substitute Parts

Part Overview

The BCR 179F E6327 is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Infineon Technologies in the PG-TSFP-3 surface mount package. This component is designed for applications requiring integrated base bias resistors, simplifying circuit design and reducing component count. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing production support, design updates, and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BCR 179F E6327 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor type: PNP - Pre-Biased configuration
• Maximum collector current: 100 mA
• Collector-emitter breakdown voltage: 50 V
• Base resistor value: 10 kOhms
• Vce saturation: 300 mV maximum
• Surface mount technology

Acceptable Variation Parameters:

• Transition frequency: Substitute parts may exceed 150 MHz (higher frequency is acceptable)
• Maximum power dissipation: Substitute parts may be rated lower than 250 mW if all other parameters are met
• DC current gain: Substitute parts with hFE minimum of 100 or greater at specified test conditions are acceptable
• Collector cutoff current: Substitute parts may have lower ICBO values
• Package form factor: SOT-23 and equivalent 3-pin surface mount packages are acceptable alternatives to SOT-723

The three substitute parts listed below meet all mandatory matching criteria and are therefore direct functional equivalents for the BCR 179F E6327.

Parameter Comparison

Engineering Selection Recommendations

DTA114TCA-TP (Micro Commercial Co) — Active product status with REACH compliance. Supplied in tape and reel packaging. Transition frequency of 250 MHz exceeds the original specification. Power rating of 200 mW is lower than the original 250 mW but remains adequate for equivalent electrical performance given identical current and voltage ratings.

DTA114TCAT116 (Rohm Semiconductor) — Active product status with ROHS3 compliance and REACH unaffected designation. Supplied in tape and reel packaging. Transition frequency of 250 MHz and power rating of 200 mW follow the same profile as the Micro Commercial Co substitute.

DTA114TKAT146 (Rohm Semiconductor) — Active product status with ROHS3 compliance and REACH unaffected designation. Supplied in cut tape and Digi-Reel packaging. Highest inventory availability (125,300 pieces in stock). Transition frequency of 250 MHz and power rating of 200 mW are equivalent to other DTA114 variants. This part is recommended for applications requiring immediate availability and long-term supply continuity.

All three substitute parts are functionally equivalent to the BCR 179F E6327 across all mandatory electrical parameters. Selection among these alternatives should be based on packaging format preference, supply chain availability, and compliance documentation requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can DTA114 series parts directly replace the BCR 179F E6327 without circuit modification?

A: Yes. All three substitute parts maintain identical collector current (100 mA), collector-emitter breakdown voltage (50 V), base resistor value (10 kOhms), and saturation voltage (300 mV). The pre-biased configuration is preserved across all alternatives. No circuit redesign is required.

Q: What is the significance of the different package designations (SOT-723, SOT-23, SST3, SMT3)?

A: SOT-723 (PG-TSFP-3) is the original Infineon package. SOT-23 (TO-236-3, SC-59) is the industry-standard 3-pin surface mount package used by Micro Commercial Co and Rohm. SST3 and SMT3 are Rohm-specific package designations for SOT-23-compatible devices. All packages are mechanically and electrically compatible for PCB assembly purposes, though PCB footprint verification is required before implementation.

Q: Why do the substitute parts have higher transition frequencies (250 MHz vs. 150 MHz)?

A: Higher transition frequency indicates improved high-frequency performance. This is an acceptable variation that does not compromise substitution validity. Applications operating at or below 150 MHz will function identically. Applications requiring frequencies between 150 MHz and 250 MHz may benefit from the enhanced performance of substitute parts.

Q: Is the lower power rating (200 mW vs. 250 mW) on substitute parts a concern?

A: No. The power rating reduction is not a limiting factor for direct substitution. All parts are rated for identical maximum collector current (100 mA) and collector-emitter voltage (50 V). The lower power rating reflects manufacturing differences and does not affect functional equivalence in standard applications.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging is supplied on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut tape and Digi-Reel packaging provides smaller quantities on cut tape segments, suitable for lower-volume production or prototyping. Both formats contain identical components; packaging format selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: DTA114TCAT116 and DTA114TKAT146 (both Rohm) carry ROHS3 compliance certification. DTA114TCA-TP (Micro Commercial Co) is REACH unaffected. All parts meet current environmental and regulatory standards for electronic component manufacturing and use.

Q: Which substitute part should be selected for new designs?

A: DTA114TKAT146 is recommended for new designs due to active product status, ROHS3 compliance, highest inventory availability (125,300 pieces), and established long-term supply chain support from Rohm Semiconductor. This part provides the strongest assurance of continued availability and regulatory compliance throughout the product lifecycle.
