BCX17TC Equivalent & Substitute Parts

Part Overview

The BCX17TC is a PNP bipolar junction transistor manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-23-3 package. This device operates at 45 V collector-emitter breakdown voltage with a maximum collector current of 500 mA and is rated for 330 mW power dissipation. The BCX17TC is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Active alternatives with matching or superior electrical characteristics are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the BCX17TC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Transistor Type: PNP
Collector Current (Max): 500 mA
Collector-Emitter Breakdown Voltage (Max): 45 V
DC Current Gain (hFE Min): 100 @ 100 mA, 1 V
Mounting Type: Surface Mount
Package: SOT-23-3 compatible (TO-236-3, SC-59)
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1

Allowable Parameter Variations:

Vce Saturation: Substitute parts may range from 620 mV to 700 mV at specified test conditions
Power Dissipation: Substitute parts may range from 250 mW to 330 mW
Transition Frequency: Substitute parts may range from 80 MHz to 100 MHz
Collector Cutoff Current: Substitute parts may range from 100 nA to 200 nA

Engineering Selection Recommendations

Parametric Equivalent (Obsolete to Active Transition):

BCX17TA is a parametric equivalent to BCX17TC, sharing identical electrical specifications. However, BCX17TA is also classified as obsolete. For new designs and production continuity, selection should prioritize active production parts.

Primary Active Substitutes (Diodes Incorporated):

BC807-16-7-F is an active production part from Diodes Incorporated with full electrical compatibility. This part maintains the 100 MHz transition frequency and 45 V breakdown voltage of the original BCX17TC. The Vce saturation specification increases from 620 mV to 700 mV, which remains within acceptable operating margins for most applications. Power dissipation is rated at 310 mW, slightly lower than the original 330 mW specification.

Active Substitutes (onsemi):

BC807-16LT1G and SBC807-16LT1G are active production parts from onsemi. Both maintain 100 MHz transition frequency and 45 V breakdown voltage. SBC807-16LT1G includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. BCX17LT1G provides matching Vce saturation characteristics (620 mV) to the original BCX17TC but does not specify transition frequency in the provided data.

Active Substitutes (Nexperia USA Inc.):

BC807,215 and BC807-16,215 are active production parts with AEC-Q101 automotive qualification. These parts operate at 80 MHz transition frequency and 250 mW power dissipation, representing reduced performance specifications compared to BCX17TC. Selection of these parts is appropriate only when the reduced frequency and power ratings are acceptable for the application.

BCX17,215 is an active production part from Nexperia USA Inc. with matching Vce saturation (620 mV) to BCX17TC and AEC-Q101 automotive qualification. Transition frequency is specified at 80 MHz and power dissipation at 250 mW.

Active Substitutes (Micro Commercial Co):

BC807-16-TP is an active production part with 100 MHz transition frequency and 300 mW power dissipation, providing close electrical alignment with BCX17TC specifications.

Compliance and Certification:

All substitute parts listed are ROHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited). Parts designated with AEC-Q101 qualification (BC807,215; BC807-16,215; BCX17,215; SBC807-16LT1G; SBC807-16LT3G) are suitable for automotive applications. Non-automotive-qualified parts (BC807-16-7-F; BC807-16-TP; BC807-16LT1G; BCX17LT1G) are suitable for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can BCX17TC be directly replaced with BC807-16LT1G?

A: Yes. BC807-16LT1G meets all mandatory electrical parameters: 500 mA collector current, 45 V breakdown voltage, 100 @ 100 mA, 1 V DC current gain, and SOT-23-3 package compatibility. The Vce saturation increases from 620 mV to 700 mV, which is within acceptable operating margins. Both parts operate across −55°C to 150°C temperature range.

Q: What is the difference between BC807-16LT1G and SBC807-16LT1G?

A: Both parts share identical electrical specifications: 500 mA collector current, 45 V breakdown voltage, 100 MHz transition frequency, and SOT-23-3 package. The primary difference is that SBC807-16LT1G carries AEC-Q101 automotive qualification, making it suitable for automotive applications. BC807-16LT1G is suitable for industrial and consumer applications.

Q: Why do some substitute parts specify 80 MHz transition frequency instead of 100 MHz?

A: BC807,215 and BC807-16,215 from Nexperia USA Inc. are specified with 80 MHz transition frequency, which is lower than the original BCX17TC specification of 100 MHz. These parts remain electrically compatible for applications where the reduced frequency margin is acceptable. Selection should be based on circuit bandwidth requirements.

Q: Are all substitute parts available in the same package as BCX17TC?

A: Yes. All substitute parts listed are available in SOT-23-3 package (also designated TO-236-3 or SC-59), which is physically and electrically compatible with BCX17TC. Pinout and lead spacing are identical across all listed parts.

Q: Which substitute part has the closest electrical match to BCX17TC?

A: BCX17TA is a parametric equivalent with identical specifications (620 mV Vce saturation, 330 mW power dissipation, 100 MHz transition frequency). However, BCX17TA is obsolete. Among active production parts, BC807-16-7-F from Diodes Incorporated provides the closest match, with only minor variations in power dissipation (310 mW vs. 330 mW) and Vce saturation (700 mV vs. 620 mV).

Q: Can BCX17TC be used in automotive applications?

A: BCX17TC does not carry AEC-Q101 automotive qualification. For automotive applications, select SBC807-16LT1G, SBC807-16LT3G, BC807,215, BC807-16,215, or BCX17,215, all of which are AEC-Q101 qualified.

Q: What is the inventory status of substitute parts?

A: BC807-16LT1G (onsemi) has the highest inventory at 146,930 pieces. BCX17LT1G (onsemi) has 293,100 pieces available. BC807-16,215 (Nexperia USA Inc.) has 28,968 pieces. Other substitute parts have lower inventory levels ranging from 2,810 to 15,635 pieces. Inventory levels should be verified with suppliers for production planning.

Q: Are there any RoHS or REACH compliance differences between BCX17TC and substitute parts?

A: No. BCX17TC and all listed substitute parts are ROHS3 compliant and REACH unaffected. All parts carry Moisture Sensitivity Level 1 (unlimited), indicating no special moisture handling requirements.
