DMA566030R Equivalent & Substitute Parts

Part Overview

The DMA566030R is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Panasonic Electronic Components in a surface mount SMini6-F3-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 to maintain design continuity and procurement availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA566030R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Transistor configuration: 2 PNP - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Internal base resistor (R1): 47kOhms
• Internal emitter-base resistor (R2): 47kOhms
• Maximum power dissipation: 150mW
• Surface mount technology

Allowable Variation Parameters:

• Collector-emitter breakdown voltage: Substitute must meet or exceed 50V
• DC current gain (hFE): Substitute values within acceptable circuit operating margins
• Vce saturation: Substitute values within acceptable switching performance margins
• Package form factor: Different surface mount packages acceptable if pin configuration and electrical function remain equivalent

The substitute parts UMB2NFHATN and UMB2NTN from Rohm Semiconductor satisfy these criteria through identical transistor configuration, matching internal resistor values, equivalent current and power ratings, and compatible surface mount packaging.

Engineering Selection Recommendations

UMB2NTN (Rohm Semiconductor) - Primary Substitute

The UMB2NTN provides direct functional equivalence to the DMA566030R across all critical electrical parameters. This part maintains the 50V collector-emitter breakdown voltage specification, 100mA maximum collector current, and identical internal resistor configuration (47kOhms base and emitter-base). The UMB2NTN is currently in active production status with 5950 pieces in stock, ensuring procurement continuity. The part carries ROHS3 compliance and AEC-Q101 automotive qualification, meeting or exceeding the RoHS compliance of the original part. The UMT6 package (6-TSSOP, SC-88, SOT-363) is mechanically and electrically compatible with the SMini6-F3-B package for surface mount applications. The 250MHz transition frequency specification of the UMB2NTN exceeds the performance envelope of the original part, providing additional operational margin.

UMB2NFHATN (Rohm Semiconductor) - Secondary Substitute

The UMB2NFHATN functions as an alternative substitute with identical transistor configuration, internal resistor values, and power rating. This part is also in active production with 4460 pieces in stock. The UMB2NFHATN carries automotive-grade qualification (AEC-Q101) and ROHS3 compliance. The primary distinction is the absence of a specified collector-emitter breakdown voltage in the provided data; however, the part maintains all other critical electrical parameters. The UMT6 package provides equivalent surface mount compatibility. Selection of this part requires confirmation that the unspecified breakdown voltage meets circuit requirements.

Package Consideration

Both substitute parts utilize the UMT6 package (6-TSSOP, SC-88, SOT-363) rather than the original SMini6-F3-B package. PCB layout modifications may be required to accommodate the different package footprint. Pin configuration and electrical function remain equivalent for direct substitution in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the UMB2NTN directly replace the DMA566030R without circuit modification?

A: The UMB2NTN provides electrical equivalence across all specified parameters. However, the package change from SMini6-F3-B to UMT6 requires PCB footprint modification. Once the footprint is updated, the parts are functionally interchangeable.

Q: What is the significance of the 250MHz transition frequency in the Rohm substitutes?

A: The transition frequency specification indicates the frequency at which the transistor current gain drops to unity. The DMA566030R does not specify this parameter. The 250MHz specification of the UMB2NTN and UMB2NFHATN represents additional performance capability and does not restrict substitution in applications designed for the original part.

Q: Why does the UMB2NFHATN lack a specified collector-emitter breakdown voltage?

A: The provided data for UMB2NFHATN does not include this specification. The DMA566030R specifies 50V. The UMB2NTN explicitly matches this 50V specification and is the recommended primary substitute when breakdown voltage specification is critical to circuit design.

Q: Are the internal resistor values identical between the main part and substitutes?

A: Yes. Both the DMA566030R and the substitute parts (UMB2NFHATN and UMB2NTN) contain 47kOhms base resistors (R1) and 47kOhms emitter-base resistors (R2). This internal resistor matching is a primary criterion for substitution equivalence.

Q: What is the difference in Vce saturation between the original and substitute parts?

A: The DMA566030R specifies 250mV maximum saturation voltage at 500µA base current and 10mA collector current. Both Rohm substitutes specify 300mV under the same conditions. This 50mV difference represents acceptable variation within typical switching circuit design margins and does not preclude substitution.

Q: Do the substitute parts carry automotive qualification?

A: The UMB2NFHATN and UMB2NTN both carry AEC-Q101 automotive qualification. The original DMA566030R does not specify automotive qualification in the provided data. The automotive-grade substitutes provide enhanced reliability for applications requiring this qualification level.

Q: Is PCB layout redesign mandatory for substitution?

A: Yes. The package change from SMini6-F3-B (6-SMD, Flat Leads) to UMT6 (6-TSSOP, SC-88, SOT-363) requires PCB footprint modification. The electrical function remains equivalent once the physical layout is updated.

Q: What is the inventory status of the substitute parts?

A: UMB2NTN has 5950 pieces in stock (primary substitute). UMB2NFHATN has 4460 pieces in stock (secondary substitute). Both parts are in active production status, ensuring long-term procurement availability compared to the discontinued DMA566030R.
