Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete BC856BSHX is determined by electrical and mechanical parameter compatibility within the Bipolar (BJT) Transistor Array category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 65V
• Vce saturation characteristics: 300mV @ 5mA, 100mA
• Collector cutoff current: 15nA (ICBO)
• DC current gain (hFE): 200 @ 2mA, 5V
• Transition frequency: 100MHz
• Package type: 6-TSSOP, SC-88, SOT-363
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 3 (168 Hours)

The BC856BSH-QX meets all critical electrical parameters and maintains identical package specifications, enabling direct functional substitution. The substitute part is manufactured by the same supplier (Nexperia USA Inc.) and carries active product status with automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The BC856BSH-QX is the manufacturer-recommended substitute for the obsolete BC856BSHX. Both components share identical electrical specifications for collector current, breakdown voltage, saturation characteristics, current gain, and transition frequency. Package compatibility is confirmed across 6-TSSOP, SC-88, and SOT-363 designations, enabling direct board-level substitution without layout modification.

The BC856BSH-QX carries active product status from Nexperia USA Inc., ensuring ongoing availability and supply chain continuity. The substitute part maintains ROHS3 compliance and identical moisture sensitivity classification (MSL 3, 168 Hours), satisfying environmental and handling requirements equivalent to the original component.

The BC856BSH-QX includes AEC-Q101 automotive qualification, providing enhanced reliability documentation suitable for applications requiring automotive-grade component traceability. The substitute part is rated for a maximum operating temperature of 150°C (versus 175°C for the main part) and maximum power dissipation of 200mW (versus 270mW for the main part). These reduced ratings remain within acceptable margins for standard BJT transistor array applications operating within typical industrial and commercial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the BC856BSH-QX be used as a direct replacement for the BC856BSHX in existing designs?

A: Yes. The BC856BSH-QX meets all critical electrical parameters (collector current, breakdown voltage, saturation characteristics, current gain, and transition frequency) and shares identical package specifications (6-TSSOP, SC-88, SOT-363). Direct substitution is supported without circuit redesign or board layout modification.

Q: What are the differences between the BC856BSHX and BC856BSH-QX?

A: The primary differences are product status and thermal ratings. The BC856BSHX is obsolete; the BC856BSH-QX is active. The BC856BSH-QX has a maximum operating temperature of 150°C (versus 175°C) and maximum power dissipation of 200mW (versus 270mW). The BC856BSH-QX includes AEC-Q101 automotive qualification. All other electrical and mechanical parameters are identical.

Q: Are the moisture sensitivity levels the same for both parts?

A: Yes. Both the BC856BSHX and BC856BSH-QX are classified as MSL 3 (168 Hours), requiring identical handling and storage protocols.

Q: Does the BC856BSH-QX meet RoHS compliance requirements?

A: Yes. The BC856BSH-QX is ROHS3 compliant, matching the compliance status of the BC856BSHX.

Q: What is the significance of the AEC-Q101 qualification on the BC856BSH-QX?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. This certification indicates the BC856BSH-QX has undergone enhanced reliability testing and quality assurance protocols suitable for automotive applications. This qualification is not present on the obsolete BC856BSHX.

Q: Can the BC856BSH-QX be used in high-temperature applications requiring 175°C operation?

A: The BC856BSH-QX is rated for a maximum operating temperature of 150°C. Applications requiring sustained operation at 175°C must evaluate alternative components or operate the BC856BSH-QX within its specified temperature range.

Q: Are there any package or pinout differences between these components?

A: No. Both components use the 6-TSSOP package (also designated SC-88 or SOT-363) with identical pinout and mechanical specifications, enabling direct board-level substitution.
