TSA874CW Equivalent & Substitute Parts

Part Overview

The TSA874CW is an active production PNP bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. This surface mount device operates at 500 V collector-emitter breakdown voltage with a maximum collector current of 150 mA and 1 W power dissipation capability. The TSA874CW is specified for general-purpose switching and amplification applications requiring high-voltage PNP performance in compact SOT-223 packaging.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within established parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the TSA874CW is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Transistor type must be PNP
• Voltage - Collector Emitter Breakdown (Max) must equal or exceed 500 V
• Current - Collector (Ic) (Max) must equal or exceed 150 mA
• Vce Saturation (Max) @ Ib, Ic must equal or be lower than 500 mV @ 10 mA, 50 mA
• Current - Collector Cutoff (Max) must equal or be lower than 100 nA
• Operating Temperature Range must encompass -55°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type must be Surface Mount
• Package / Case must be SOT-223 or compatible variant (SOT-223-3)

Compliance Equivalence Criteria:

• Product Status must be Active
• RoHS Status must be ROHS3 Compliant or equivalent

The FZT560TC meets all substitution criteria and is classified as an equivalent substitute for the TSA874CW.

Engineering Selection Recommendations

TSA874CW (Primary Selection)

The TSA874CW is the specified component and remains the primary selection when available. This part is in active production status with ROHS3 compliance and maintains full inventory availability. Current stock of 2,152 pieces supports immediate procurement.

FZT560TC (Substitute Selection)

The FZT560TC is a qualified substitute when TSA874CW availability is constrained. This part is manufactured by Diodes Incorporated and maintains active production status with ROHS3 compliance. The FZT560TC meets or exceeds all critical electrical parameters including voltage, current, and saturation specifications. The substitute provides enhanced performance characteristics with 2 W maximum power dissipation and 60 MHz transition frequency compared to the primary part's 1 W and 50 MHz specifications. Both devices utilize compatible SOT-223 surface mount packaging. Current inventory of 1,116 pieces is available for the FZT560TC.

Both parts are compliant with REACH regulations and classified under ECCN EAR99 with identical HTSUS coding (8541.29.0075), confirming regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the FZT560TC be used as a direct replacement for the TSA874CW in all applications?

A: The FZT560TC meets all critical electrical specifications for the TSA874CW including voltage, current, and saturation parameters. Both devices are surface mount PNP transistors in compatible SOT-223 packaging. The FZT560TC provides equal or superior performance across all specified parameters. Direct substitution is supported for applications within the defined electrical and thermal operating ranges.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Diodes Incorporated) and enhanced performance specifications in the FZT560TC. The FZT560TC provides 2 W maximum power dissipation compared to 1 W for the TSA874CW, and 60 MHz transition frequency compared to 50 MHz. Both parts maintain identical voltage, current, and saturation specifications. DC current gain is specified at different test conditions but does not affect substitution eligibility.

Q: Are the SOT-223 and SOT-223-3 packages mechanically compatible?

A: Both packages are surface mount variants of the SOT-223 family with identical pin pitch and footprint compatibility. The SOT-223-3 designation indicates a three-terminal configuration, which is standard for both the TSA874CW and FZT560TC. PCB layout and reflow soldering processes are compatible between these package variants.

Q: What compliance certifications apply to both parts?

A: Both the TSA874CW and FZT560TC are ROHS3 compliant and REACH unaffected. Both parts are classified under ECCN EAR99 and HTSUS code 8541.29.0075, confirming equivalent regulatory status for procurement, inventory management, and international trade purposes.

Q: Under what circumstances should substitution be considered?

A: Substitution of the FZT560TC for the TSA874CW is appropriate when primary component availability is limited or when supply chain lead times require alternative sourcing. Both parts maintain active production status and equivalent electrical performance within specified operating parameters. Substitution does not require design modification or circuit re-qualification when used within the defined electrical and thermal operating ranges.

Q: How do the operating temperature ranges compare?

A: Both the TSA874CW and FZT560TC operate across the identical temperature range of -55°C to 150°C junction temperature. This equivalence ensures thermal performance compatibility across all specified operating environments.
