Key Parameters

Substitute Part Grouping Explanation

Substitution of the BC856BM-TP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor polarity: PNP configuration
• Maximum collector current: 100 mA
• Collector-emitter breakdown voltage: 65 V
• Operating temperature range compatibility: -55°C ~ 150°C

Mechanical Equivalence Criteria:

• Surface mount technology
• Package classification: SC-101 / SOT-883 family
• Moisture sensitivity level: 1 (Unlimited)

Compliance Equivalence Criteria:

• RoHS3 compliance
• REACH unaffected status

The BC856BL3-TP qualifies as a direct substitute based on matching all primary electrical specifications (PNP type, 100 mA Ic max, 65 V Vce breakdown) and compliance requirements. The substitute maintains the same base product number (BC856) and shares identical RoHS and REACH classifications. The primary distinction is the transition from obsolete to active product status and the change in supplier device package designation from SOT-883 to DFN1006-3, both within the SC-101 package family.

Engineering Selection Recommendations

The BC856BL3-TP is the designated substitute for the obsolete BC856BM-TP. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The BC856BL3-TP maintains active product status, ensuring continued availability and manufacturing support. This addresses the obsolescence constraint of the original BC856BM-TP.

Electrical Specification Equivalence: Both devices share identical maximum ratings for collector current (100 mA) and collector-emitter breakdown voltage (65 V), ensuring functional compatibility in existing circuit designs without modification.

Compliance Continuity: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new production and replacement applications.

Packaging Compatibility: Both devices are classified within the SC-101 / SOT-883 package family and employ surface mount technology. The transition from SOT-883 to DFN1006-3 supplier device package designation represents a refinement within the same package classification, maintaining footprint and assembly compatibility.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the BC856BL3-TP be used as a direct replacement for the BC856BM-TP in existing designs?

A: Yes. The BC856BL3-TP meets all critical electrical specifications of the BC856BM-TP, including PNP polarity, 100 mA maximum collector current, and 65 V collector-emitter breakdown voltage. Both devices are surface mount components within the SC-101 / SOT-883 package family and require no circuit modifications.

Q: What is the difference between the SOT-883 and DFN1006-3 package designations?

A: Both designations refer to packages within the SC-101 family classification. The DFN1006-3 represents the supplier device package for the BC856BL3-TP, while SOT-883 is the designation for the BC856BM-TP. Both maintain equivalent footprint and assembly compatibility for surface mount applications.

Q: Are there any electrical parameter differences between these parts that would affect circuit performance?

A: The provided specifications confirm that both devices share identical maximum ratings for collector current (100 mA) and collector-emitter breakdown voltage (65 V). The BC856BL3-TP includes a maximum power dissipation specification of 150 mW, which is not specified for the BC856BM-TP. This additional specification does not indicate reduced capability but rather provides additional design guidance for the active substitute.

Q: Does the BC856BL3-TP maintain the same compliance certifications as the BC856BM-TP?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance status. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the BC856BM-TP classified as obsolete?

A: The BC856BM-TP is listed as obsolete by the manufacturer. The BC856BL3-TP is the active equivalent that maintains all functional and electrical specifications while ensuring continued component availability and manufacturing support.
