DMA202010R Equivalent & Substitute Parts

Part Overview

The DMA202010R is a dual PNP bipolar junction transistor (BJT) array manufactured by Panasonic Electronic Components, designed for general-purpose amplification and switching applications. This component features a 50V collector-emitter breakdown voltage rating, 100mA maximum collector current, and 300mW power dissipation capability in a surface mount Mini5-G3-B package (SC-74A, SOT-753).

The DMA202010R is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from Rohm Semiconductor that maintain electrical compatibility while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA202010R is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: Dual PNP (2 PNP)
• Collector-emitter breakdown voltage: 50V minimum
• Maximum collector current: Equal to or greater than 100mA
• Power dissipation: Equal to or greater than 300mW
• Transition frequency: Equal to or greater than 150MHz
• Operating temperature range: 150°C maximum junction temperature

Mechanical Compatibility Criteria:

• Mounting type: Surface mount only
• Package compatibility: SC-74A/SOT-753 footprint or equivalent surface mount packages with compatible pinout

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating: 1 (Unlimited) preferred

The substitute parts identified (IMT1AT110 and UMT1NFHATN) meet or exceed all electrical parameters of the DMA202010R while maintaining RoHS3 compliance and MSL-1 rating. Both substitutes are currently active products with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

IMT1AT110 (Rohm Semiconductor): The IMT1AT110 provides direct electrical substitution with enhanced current handling capability (150mA vs. 100mA). This part maintains the 300mW power rating and 50V breakdown voltage specification. The SC-74/SOT-457 package is mechanically compatible with standard surface mount assembly processes. This part is recommended for applications where the original DMA202010R specifications are met or exceeded and package footprint compatibility can be accommodated. Active product status ensures long-term availability.

UMT1NFHATN (Rohm Semiconductor): The UMT1NFHATN is an automotive-grade substitute (AEC-Q101 qualified) with identical electrical ratings to the IMT1AT110 except for reduced maximum power dissipation (150mW vs. 300mW). This part is suitable for applications requiring automotive qualification or enhanced reliability standards. The 6-TSSOP/SC-88/SOT-363 package requires PCB layout verification for footprint compatibility. Active product status and automotive qualification provide extended product lifecycle assurance.

Selection Criteria:

• Choose IMT1AT110 for standard industrial applications requiring full 300mW power capability
• Choose UMT1NFHATN for automotive applications or where AEC-Q101 qualification is required
• Verify PCB footprint compatibility with selected package type before design implementation
• Both substitutes are ROHS3 compliant and MSL-1 rated, matching the original part specifications

Frequently Asked Questions (FAQ)

Q: Can the IMT1AT110 or UMT1NFHATN be used as direct replacements for the DMA202010R?

A: Both parts meet the core electrical specifications of the DMA202010R (50V breakdown voltage, dual PNP configuration, 150°C operating temperature, RoHS3 compliance). However, package footprint differences must be verified. The DMA202010R uses SC-74A/SOT-753, while IMT1AT110 uses SC-74/SOT-457 and UMT1NFHATN uses 6-TSSOP/SC-88/SOT-363. PCB layout compatibility must be confirmed before substitution.

Q: What are the key electrical differences between these parts?

A: The primary differences are collector current rating (DMA202010R: 100mA; substitutes: 150mA) and power dissipation (DMA202010R and IMT1AT110: 300mW; UMT1NFHATN: 150mW). Both substitutes have slightly lower transition frequency (140MHz vs. 150MHz). The substitutes feature lower collector cutoff current (100nA vs. 100µA), indicating improved leakage characteristics.

Q: Why is the UMT1NFHATN rated at 150mW instead of 300mW?

A: The UMT1NFHATN is designed for automotive applications with AEC-Q101 qualification. The reduced power rating reflects the specific thermal and reliability requirements of automotive-grade components. This part remains suitable for applications within the 150mW power envelope.

Q: Are both substitute parts currently available?

A: Yes. The IMT1AT110 has 125,200 pieces in stock, and the UMT1NFHATN has 15,906 pieces in stock. Both are active products with confirmed availability from DiGi Electronics.

Q: What is the significance of the AEC-Q101 qualification on the UMT1NFHATN?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. This certification indicates the part meets automotive reliability, quality, and performance requirements. Selection of UMT1NFHATN is mandatory for automotive applications requiring this qualification.

Q: Do the substitute parts have the same pinout as the DMA202010R?

A: Both substitute parts are dual PNP transistor arrays with compatible functional pinout (two independent PNP transistors). However, physical package differences (SC-74A vs. SC-74 vs. 6-TSSOP) require PCB footprint verification. Pin numbering and spacing differ between package types.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. All three parts (DMA202010R, IMT1AT110, and UMT1NFHATN) carry MSL-1 rating, eliminating moisture-related handling constraints during storage and assembly.
