Equivalent & Substitute Parts Reference: TSA884CX

Part Overview

The TSA884CX is a PNP bipolar (BJT) transistor manufactured by Taiwan Semiconductor Corporation, offering a maximum collector-emitter breakdown voltage of 500 V, a collector current of up to 150 mA, and a typical frequency transition of 50 MHz, housed in an SOT-23 surface mount package. The product holds an active status, is compliant with ROHS3 and REACH standards, and is available in new original inventory. Due to inventory management, supply chain optimization, or lifecycle requirements, identification of electrically and mechanically compatible alternative models is necessary within the Transistors, Bipolar (BJT) category.

Engineering Selection Recommendations

All listed parts maintain active product status, ROHS3 compliance, and REACH unaffected status. These compliance certifications align with regulatory and environmental requirements for electronics manufacturing and component selection.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must match when selecting a substitute for TSA884CX?
A1: Substitutes must maintain identical transistor type (PNP), collector current rating (150 mA), collector-emitter breakdown voltage (500 V), and compatible saturation voltage at specified current levels.

Q2: Are package and footprint considerations relevant during substitution?
A2: Yes. All substitutes provided feature surface mount configurations and SOT-23, TO-236-3, SC-59, or SOT-23-3 packages, which support drop-in compatibility.

Q3: How does compliance affect substitute selection?
A3: ROHS3 compliant and REACH unaffected status are mandatory for regulatory conformity. All listed alternatives meet these criteria.

Q4: Are there differences in power rating or transition frequency among substitutes?
A4: Substitute FMMT560QTA provides higher power dissipation (500 mW) and transition frequency (60 MHz) compared to TSA884CX.

Q5: Is the hFE value required to be identical for direct substitution?
A5: The DC current gain should be compared for application-specific requirements. On the provided list, FMMT560QTA has a lower hFE at 80 @ 50mA, 10V versus TSA884CX's 150 @ 1mA, 10V.

Q6: Are substitutes available in tape & reel packaging for automated assembly?
A6: Yes. All substitutes are provided in tape & reel packaging, suitable for surface mount and automated placement processes.
