DMA264010R Equivalent & Substitute Parts

Part Overview

The DMA264010R is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Panasonic Electronic Components in a Surface Mount Mini6-G4-B package. This component integrates two PNP transistors with internal biasing resistors, designed for switching and amplification applications requiring 50V collector-emitter breakdown voltage and 100mA maximum collector current. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA264010R is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor configuration: 2 PNP - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Internal base resistor (R1): 10kOhms
• Internal emitter-base resistor (R2): 10kOhms
• Mounting type: Surface Mount
• Moisture sensitivity level: 1 (Unlimited)

Acceptable Variation Parameters:

• DC current gain (hFE) minimum: 30 or higher at specified conditions
• Vce saturation: up to 300mV at specified conditions
• Collector cutoff current: 500nA maximum
• Power dissipation: 150mW or higher
• Package case designation: SOT-23-6, SC-74, SOT-457, 6-TSSOP, SC-88, SOT-363 (all equivalent 6-pin surface mount packages)
• Transition frequency: 250MHz or higher (when specified)

The identified substitute parts IMB11AT110 and UMB11NFHATN maintain all critical electrical parameters and are housed in physically compatible surface mount packages suitable for direct board-level replacement.

Engineering Selection Recommendations

IMB11AT110 (Rohm Semiconductor)

The IMB11AT110 is an active product with full ROHS3 compliance and REACH unaffected status. This part maintains electrical equivalence across all critical parameters: 100mA collector current, 50V breakdown voltage, and 10kOhm internal resistors. The 300mW power rating matches the original specification. The SC-74 and SOT-457 package designations are physically compatible with SOT-23-6 footprints on standard PCB layouts. Transition frequency specification of 250MHz exceeds the original part's undocumented frequency performance. Inventory availability of 30,300 pieces supports production requirements.

UMB11NFHATN (Rohm Semiconductor)

The UMB11NFHATN is an active product with ROHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification. This part maintains electrical equivalence across all critical parameters with identical collector current, breakdown voltage, and internal resistor values. The 150mW power rating is lower than the original 300mW specification and must be evaluated against application power dissipation requirements. The 6-TSSOP, SC-88, and SOT-363 package designations are physically compatible with SOT-23-6 footprints. Transition frequency of 250MHz is specified. Automotive-grade qualification provides enhanced reliability for demanding environments. Inventory availability of 4,100 pieces supports moderate production volumes.

Selection Criteria:

Choose IMB11AT110 for applications requiring full 300mW power dissipation capability and maximum inventory availability. Choose UMB11NFHATN for automotive applications, safety-critical systems, or environments requiring AEC-Q101 qualification, provided application power dissipation does not exceed 150mW.

Frequently Asked Questions (FAQ)

Q: Can IMB11AT110 and UMB11NFHATN be used interchangeably with DMA264010R?

A: Both parts are electrically equivalent across all critical parameters: dual PNP pre-biased configuration, 100mA collector current, 50V breakdown voltage, and 10kOhm internal resistors. Physical package compatibility exists across all three parts in standard surface mount applications. Power dissipation differences must be evaluated for specific circuit requirements.

Q: What is the difference in power rating between the substitute parts?

A: IMB11AT110 is rated for 300mW maximum power dissipation, matching the original DMA264010R specification. UMB11NFHATN is rated for 150mW maximum power dissipation. Applications requiring sustained power dissipation above 150mW must use IMB11AT110 or the original part.

Q: Are the package dimensions identical across DMA264010R, IMB11AT110, and UMB11NFHATN?

A: All three parts use 6-pin surface mount packages (SOT-23-6, SC-74/SOT-457, and 6-TSSOP/SC-88/SOT-363 respectively). These package families share compatible pin spacing and footprint dimensions suitable for direct PCB replacement without layout modification.

Q: What compliance certifications apply to the substitute parts?

A: IMB11AT110 carries ROHS3 compliance and REACH unaffected status. UMB11NFHATN carries ROHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification. Both parts exceed the original RoHS compliance requirement.

Q: How do the DC current gain specifications compare?

A: DMA264010R specifies minimum hFE of 35 at 5mA collector current and 10V collector-emitter voltage. IMB11AT110 and UMB11NFHATN specify minimum hFE of 30 at 5mA collector current and 5V collector-emitter voltage. The lower test voltage in substitute parts results in slightly lower gain specification, but both parts exceed minimum gain requirements for standard switching applications.

Q: What is the significance of the 250MHz transition frequency in IMB11AT110 and UMB11NFHATN?

A: Transition frequency (fT) of 250MHz indicates the frequency at which current gain drops to unity. This specification is not provided for the original DMA264010R. The 250MHz specification in substitute parts confirms suitability for high-frequency switching applications and represents enhanced performance relative to the original part.

Q: Are moisture sensitivity levels equivalent across all three parts?

A: Yes. DMA264010R, IMB11AT110, and UMB11NFHATN all carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Which substitute part should be selected for new design implementations?

A: IMB11AT110 is recommended for new designs requiring maximum power dissipation capability and broad inventory availability. UMB11NFHATN is recommended for automotive applications, safety-critical systems, or designs requiring AEC-Q101 qualification, provided application power dissipation remains below 150mW.
