Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC266060R is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Transistor configuration: Dual NPN pre-biased topology
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Base resistor value: 4.7kOhms
• DC current gain minimum: 160 @ 5mA, 10V
• Vce saturation: 250mV maximum
• Collector cutoff current: 500nA maximum
• Mounting technology: Surface Mount

Package Compatibility: The DMC266060R uses a SOT-23-6 (Mini6-G4-B) package. Substitute parts must maintain electrical equivalence while accommodating package variations within the 6-pin surface mount family (SOT-363, SC-88, SC-70-6).

The MUN5216DW1T1G meets all functional electrical parameters and operates within the same performance envelope, with the exception of maximum power dissipation (250mW versus 300mW for the original part). This reduction does not affect substitution validity for applications within the specified thermal limits.

Engineering Selection Recommendations

Product Status Consideration: The DMC266060R is classified as obsolete. The MUN5216DW1T1G is an active product from onsemi, ensuring ongoing availability and manufacturing support for new designs and production continuity.

Compliance and Certifications: The MUN5216DW1T1G carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in regulated markets. Both parts share identical ECCN (EAR99) and HTSUS (8541.21.0095) classifications.

Inventory and Supply Chain: The MUN5216DW1T1G maintains significantly higher inventory levels (73,260 pieces) compared to the obsolete DMC266060R (1,104 pieces), supporting long-term supply chain stability.

Power Dissipation: The MUN5216DW1T1G operates at 250mW maximum power dissipation versus 300mW for the original part. This 50mW reduction requires thermal design verification for applications operating at the upper limits of the original specification. For standard switching and amplification applications, this difference does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the MUN5216DW1T1G directly replace the DMC266060R in existing designs?

A: Yes, the MUN5216DW1T1G provides electrical equivalence across all critical parameters: dual NPN pre-biased configuration, 100mA collector current, 50V breakdown voltage, 4.7kOhm base resistor, and identical DC current gain specifications. Package footprints differ (SOT-23-6 versus SOT-363), requiring PCB layout modification.

Q: What is the significance of the power dissipation difference (300mW versus 250mW)?

A: The MUN5216DW1T1G operates at 250mW maximum, 50mW lower than the original specification. For applications dissipating power below 250mW, no thermal impact occurs. Applications requiring sustained operation above 250mW require thermal analysis to confirm adequate heat dissipation through PCB copper area and ambient conditions.

Q: Are there package compatibility considerations?

A: The DMC266060R uses SOT-23-6 (Mini6-G4-B) packaging. The MUN5216DW1T1G uses 6-TSSOP/SC-88/SOT-363 packaging. Both are 6-pin surface mount packages with identical pin counts and electrical function assignments. PCB footprint redesign is required; however, the packages are mechanically and electrically compatible within the dual NPN pre-biased transistor family.

Q: What certifications apply to the MUN5216DW1T1G?

A: The MUN5216DW1T1G is RoHS3 compliant and REACH unaffected. Both parts share EAR99 export classification and 8541.21.0095 HTSUS code. Moisture sensitivity level is 1 (unlimited) for both devices.

Q: Is the MUN5216DW1T1G suitable for new product designs?

A: Yes. The MUN5216DW1T1G is an active product with robust supply availability. It meets all functional requirements of the obsolete DMC266060R and carries current regulatory compliance certifications, making it the appropriate choice for new designs requiring dual NPN pre-biased transistor functionality.

Q: How do the saturation voltage specifications compare?

A: Both parts specify 250mV maximum Vce saturation. The DMC266060R is rated at 500µA base current and 10mA collector current, while the MUN5216DW1T1G is rated at 1mA base current and 10mA collector current. Both achieve equivalent saturation performance within their respective operating conditions.
