DMA561010R Equivalent & Substitute Parts

Part Overview

The DMA561010R is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Panasonic Electronic Components in a surface mount SMini5-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 currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain electrical compatibility across critical parameters including voltage ratings, current specifications, internal resistor values, and saturation characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA561010R is determined by strict equivalence across the following critical parameters:

Mandatory Electrical Equivalence:

• 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
• Maximum power dissipation: 150mW
• Collector cutoff current: 500nA

Acceptable Variations:

• DC current gain (hFE) may vary within device specifications
• Vce saturation may vary within specified limits
• Transition frequency may exceed the original specification
• Package form factor may differ provided mounting type remains surface mount
• Product status may transition from discontinued to active

The identified substitute parts UMA9NTR and UMB11NFHATN satisfy all mandatory electrical equivalence criteria while offering enhanced specifications (transition frequency of 250MHz) and active product status. Package differences require mechanical verification during board redesign.

Engineering Selection Recommendations

UMA9NTR Selection Criteria: The UMA9NTR from Rohm Semiconductor provides direct electrical equivalence to the DMA561010R across all mandatory parameters. This part is currently in active production status, ensuring long-term availability. ROHS3 compliance and MSL 1 rating match the original specification. The UMT5 package (5-TSSOP, SC-70-5, SOT-353) differs from the original SMini5-F3-B footprint and requires PCB layout modification. Transition frequency specification of 250MHz exceeds the original part's undocumented frequency capability, providing enhanced performance margin.

UMB11NFHATN Selection Criteria: The UMB11NFHATN from Rohm Semiconductor satisfies all electrical equivalence requirements with active product status and ROHS3 compliance. This part carries AEC-Q101 automotive qualification, providing additional reliability assurance beyond standard commercial specifications. The UMT6 package (6-TSSOP, SC-88, SOT-363) requires PCB redesign compared to the original SMini5-F3-B footprint. Higher inventory availability (4100 pieces) supports production continuity. Transition frequency of 250MHz and DC current gain of 30 @ 5mA, 5V provide performance characteristics suitable for switching applications.

Recommendation Logic: Selection between UMA9NTR and UMB11NFHATN depends on application requirements and PCB constraints. For standard commercial applications, UMA9NTR offers a compact 5-pin package. For automotive or mission-critical applications requiring AEC-Q101 qualification, UMB11NFHATN is the appropriate selection. Both parts maintain electrical compatibility with the discontinued DMA561010R and support equivalent circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can UMA9NTR and UMB11NFHATN be used interchangeably with DMA561010R?

A: Both parts satisfy the mandatory electrical equivalence criteria: dual PNP pre-biased configuration, 100mA collector current, 50V breakdown voltage, 10kOhm internal resistors, and 150mW power rating. However, package differences require PCB layout modification. UMA9NTR uses a 5-pin UMT5 package while UMB11NFHATN uses a 6-pin UMT6 package, both differing from the original SMini5-F3-B footprint.

Q: What are the key differences between UMA9NTR and UMB11NFHATN?

A: Both parts provide equivalent electrical performance. UMB11NFHATN includes AEC-Q101 automotive qualification and carries a 6-pin UMT6 package configuration. UMA9NTR uses a 5-pin UMT5 package. DC current gain specifications differ slightly (20 vs. 30 @ 5mA, 5V), and Vce saturation is 300mV for both compared to 250mV for the original part.

Q: Are there package compatibility concerns?

A: Yes. The original DMA561010R uses a 5-pin SMini5-F3-B package. UMA9NTR uses 5-TSSOP (SC-70-5, SOT-353) and UMB11NFHATN uses 6-TSSOP (SC-88, SOT-363). Pin assignments and footprints differ, requiring PCB redesign and schematic verification before implementation.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both UMA9NTR and UMB11NFHATN are ROHS3 compliant, exceeding the RoHS compliance status of the original DMA561010R. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

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

A: The substitute parts specify 250MHz transition frequency, whereas the original DMA561010R does not document this parameter. This specification indicates enhanced high-frequency performance capability, providing additional design margin for switching applications. This does not affect compatibility with circuits designed for the original part.

Q: Which substitute part should be selected for automotive applications?

A: UMB11NFHATN is qualified to AEC-Q101 automotive standards, making it the appropriate selection for automotive applications. UMA9NTR is suitable for standard commercial applications.

Q: Are there inventory considerations for part selection?

A: UMB11NFHATN has higher inventory availability (4100 pieces) compared to UMA9NTR (1617 pieces). For production continuity, UMB11NFHATN may provide supply chain advantages.
