BC869-25-TP Equivalent & Substitute Parts

Part Overview

The BC869-25-TP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, designed for interface applications in surface mount configurations. This device operates at a maximum collector current of 1 A, collector-emitter breakdown voltage of 20 V, and maximum power dissipation of 500 mW. The part is currently in active product status with 906 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when design requirements permit operation with enhanced electrical characteristics. The BCX6916H6327XTSA1 from Infineon Technologies represents an alternative solution, though it carries an obsolete product status designation.

Mandatory Matching Parameters:

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 1 A
• Voltage - Collector Emitter Breakdown (Max): 20 V
• Vce Saturation (Max) @ Ib, Ic: 500mV @ 100mA, 1A
• Current - Collector Cutoff (Max): 100nA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: 100 @ 500mA, 1V
• Mounting Type: Surface Mount
• Package / Case: TO-243AA

Parameters Permitting Enhancement:

• Power - Max: Substitute may exceed 500 mW
• Frequency - Transition: Substitute may exceed 40MHz
• Operating Temperature: Substitute may extend range beyond -55°C ~ 150°C

The BCX6916H6327XTSA1 satisfies all mandatory matching parameters while providing enhanced power dissipation (3 W) and transition frequency (100MHz) capabilities.

Engineering Selection Recommendations

BC869-25-TP (Primary Selection)

The BC869-25-TP maintains active product status with confirmed inventory availability of 906 units. This part is suitable for new designs and ongoing production where supply continuity is required. The device carries REACH Unaffected status and EAR99 export classification.

BCX6916H6327XTSA1 (Substitute Selection)

The BCX6916H6327XTSA1 is designated as obsolete and carries automotive-grade qualification (AEC-Q101) with RoHS3 compliance. This part provides enhanced electrical performance through increased power dissipation (3 W versus 500 mW) and higher transition frequency (100MHz versus 40MHz). The Moisture Sensitivity Level rating of 1 (Unlimited) indicates superior moisture tolerance. Selection of this substitute is appropriate only when the obsolete status does not conflict with supply chain requirements and when the enhanced performance characteristics provide design margin benefits.

Both parts share identical core electrical specifications for collector current, breakdown voltage, saturation characteristics, and current gain, ensuring functional equivalence within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the BCX6916H6327XTSA1 directly replace the BC869-25-TP in existing designs?

A: Yes, the BCX6916H6327XTSA1 satisfies all mandatory electrical parameters of the BC869-25-TP. Both devices feature identical maximum collector current (1 A), collector-emitter breakdown voltage (20 V), saturation voltage (500mV @ 100mA, 1A), and DC current gain (100 @ 500mA, 1V). The package designation TO-243AA and surface mount configuration are identical. The substitute provides enhanced power dissipation and frequency response without reducing performance in any specified parameter.

Q: What is the significance of the product status difference between these parts?

A: The BC869-25-TP carries active product status, indicating ongoing manufacturer support, continued production, and reliable long-term availability. The BCX6916H6327XTSA1 is designated obsolete, meaning the manufacturer has discontinued production. Obsolete status does not affect electrical performance but may impact future procurement availability and manufacturer technical support.

Q: Are the SOT-89 and PG-SOT89 package designations compatible?

A: Both designations reference the same physical package form factor (TO-243AA). The PG prefix in PG-SOT89 indicates a specific supplier variant designation. The mechanical and electrical interface characteristics are compatible for PCB assembly and circuit operation.

Q: What compliance certifications apply to each part?

A: The BC869-25-TP carries REACH Unaffected status and EAR99 export classification. The BCX6916H6327XTSA1 carries RoHS3 compliance, AEC-Q101 automotive qualification, REACH Unaffected status, and EAR99 export classification. The BCX6916H6327XTSA1 provides additional automotive-grade certification suitable for applications requiring AEC-Q101 qualification.

Q: How do the power dissipation ratings affect circuit design?

A: The BC869-25-TP is rated for 500 mW maximum power dissipation, while the BCX6916H6327XTSA1 is rated for 3 W. Both devices operate within identical voltage and current specifications. The higher power rating of the substitute provides additional thermal margin in applications approaching the 500 mW limit of the primary part. Circuit designs based on the BC869-25-TP specifications operate within the BCX6916H6327XTSA1 envelope without modification.

Q: What is the operating temperature range for each device?

A: The BC869-25-TP operates from -55°C to 150°C junction temperature. The BCX6916H6327XTSA1 specifies a maximum junction temperature of 150°C. Both devices support identical maximum operating temperature. The BC869-25-TP provides extended low-temperature operation to -55°C, while the BCX6916H6327XTSA1 minimum operating temperature is not specified in the provided parameters.
