DMC264060R Equivalent & Substitute Parts

Part Overview

The DMC264060R is a pre-biased dual NPN bipolar transistor manufactured by Panasonic Electronic Components in a Surface Mount Mini6-G4-B package. This component integrates two NPN transistors with internal base resistors, designed for applications requiring compact switching and amplification functionality at 50V maximum collector-emitter breakdown voltage and 100mA maximum collector current.

The DMC264060R is discontinued at DiGi Electronics. Equivalent substitute parts are available from active manufacturers including Rohm Semiconductor and Toshiba Semiconductor and Storage, offering identical or superior electrical performance with continued product support and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC264060R is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Equivalence Parameters:

• Transistor configuration: 2 NPN - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Maximum collector-emitter breakdown voltage: 50V
• Base resistor value (R1): 4.7kOhms
• Maximum power dissipation: 300mW or greater
• Mounting type: Surface Mount
• Collector cutoff current: 500nA or lower
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Variations in secondary parameters such as DC current gain (hFE), saturation voltage (Vce), transition frequency, and package case designation do not preclude substitution when the mandatory parameters are satisfied. Package case differences (Mini6-G4-B, SMT6, SM6, UMT6) are acceptable provided the physical footprint and pin configuration are compatible with the application circuit board design.

Engineering Selection Recommendations

IMH3AT110 (Rohm Semiconductor): This substitute offers active product status with 7750 pieces in stock inventory. Electrical parameters meet all mandatory equivalence criteria. The part is ROHS3 compliant and REACH unaffected, providing regulatory compliance for current and future applications. The 250MHz transition frequency exceeds the original part specification. Package designation SC-74/SOT-457 differs from the original Mini6-G4-B; circuit board layout compatibility must be confirmed prior to implementation.

RN1610(TE85L,F) (Toshiba Semiconductor and Storage): This substitute maintains active product status with 2304 pieces in stock. All mandatory electrical parameters are satisfied. The part is RoHS compliant with MSL 1 rating. The 100nA collector cutoff current specification is superior to the original 500nA specification. The 250MHz transition frequency exceeds original specifications. Package designation SC-74/SOT-457 differs from the original Mini6-G4-B; circuit board layout compatibility must be confirmed prior to implementation.

UMH3NFHATN (Rohm Semiconductor): This substitute is qualified to AEC-Q101 automotive standards and carries active product status with 7611 pieces in stock. All mandatory electrical parameters are satisfied. ROHS3 compliance and REACH unaffected status apply. The maximum power dissipation is 150mW, which is lower than the original 300mW specification; applications requiring full 300mW dissipation capacity are not suitable for this substitute. The 250MHz transition frequency exceeds original specifications. Package designation 6-TSSOP/SC-88/SOT-363 differs from the original Mini6-G4-B; circuit board layout compatibility must be confirmed prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the IMH3AT110 directly replace the DMC264060R without circuit modifications?

A: The IMH3AT110 satisfies all mandatory electrical parameters for substitution. However, the package case differs (SC-74/SOT-457 versus Mini6-G4-B). Physical footprint and pin configuration compatibility with the existing circuit board layout must be confirmed. If the printed circuit board is designed specifically for the Mini6-G4-B package, a redesign may be required.

Q: What is the primary difference between the RN1610(TE85L,F) and the original DMC264060R?

A: Both parts meet mandatory electrical equivalence criteria. The RN1610(TE85L,F) features a lower collector cutoff current specification (100nA versus 500nA), which represents improved leakage performance. The package case designation differs (SC-74/SOT-457 versus Mini6-G4-B), requiring circuit board layout verification.

Q: Is the UMH3NFHATN suitable for all applications using the DMC264060R?

A: The UMH3NFHATN is suitable for applications where maximum power dissipation does not exceed 150mW. Applications requiring the full 300mW dissipation capacity of the original part are not compatible with this substitute. The UMH3NFHATN is qualified to AEC-Q101 automotive standards, making it appropriate for automotive applications. Package case designation differs (6-TSSOP/SC-88/SOT-363 versus Mini6-G4-B), requiring circuit board layout verification.

Q: What does "Pre-Biased" mean in the context of these dual NPN transistors?

A: Pre-biased transistors integrate internal base resistors (R1 = 4.7kOhms in this case) within the component package. These internal resistors establish bias conditions without requiring external resistor networks, reducing component count and circuit board space requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The IMH3AT110 and UMH3NFHATN are ROHS3 compliant. The RN1610(TE85L,F) is RoHS compliant. All parts meet environmental compliance requirements for current manufacturing standards.

Q: What is the significance of the 250MHz transition frequency listed for the substitute parts?

A: The transition frequency (fT) indicates the frequency at which the transistor's current gain drops to unity. The original DMC264060R does not specify this parameter. The substitute parts specify 250MHz, indicating capability for higher-frequency switching applications. This represents a performance enhancement relative to the original part specification.

Q: Can I use multiple substitute parts interchangeably within the same production run?

A: All three substitute parts meet mandatory electrical equivalence criteria and can function in the same circuit application. However, using multiple part numbers within a single production run introduces supply chain complexity and potential quality control considerations. Selection of a single substitute part is recommended for production consistency.

Q: What packaging options are available for these substitutes?

A: The IMH3AT110 and RN1610(TE85L,F) are available in Cut Tape (CT) & Digi-Reel or Tape & Reel (TR) packaging. The UMH3NFHATN is available in Cut Tape (CT) & Digi-Reel packaging. Packaging selection depends on production volume and assembly process requirements.
