DMA201010R Equivalent & Substitute Parts

Part Overview

The DMA201010R is a dual PNP bipolar junction transistor array manufactured by Panasonic Electronic Components, designed for general-purpose amplification and switching applications. This component features a 50V collector-emitter breakdown voltage, 100mA maximum collector current, and 300mW power dissipation in a Surface Mount Mini5-G3-B package (SC-74A, SOT-753).

The DMA201010R is currently discontinued at DiGi Electronics. Equivalent substitute parts are available from Rohm Semiconductor with comparable electrical specifications and enhanced availability, making substitution necessary for ongoing production and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA201010R is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence 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 Equivalence Criteria:

• Mounting type: Surface Mount
• RoHS compliance status
• Moisture sensitivity level: MSL 1 or better

Both substitute parts (IMT1AT110 and UMT1NFHATN) meet or exceed these electrical parameters. Package differences exist but do not preclude functional substitution in applications where board layout permits alternative Surface Mount packages.

Engineering Selection Recommendations

IMT1AT110 (Rohm Semiconductor): This part is recommended as the primary substitute for the DMA201010R. It maintains electrical equivalence across all critical parameters with 150mA maximum collector current (exceeding the 100mA requirement) and 300mW power dissipation matching the original specification. The part is currently in active production status with high inventory availability (125,200 pieces). ROHS3 compliance and MSL 1 rating ensure environmental and handling compatibility. The SC-74 (SOT-457) package is mechanically similar to the original SC-74A (SOT-753) package, requiring minimal board layout modification.

UMT1NFHATN (Rohm Semiconductor): This part qualifies as a secondary substitute with full electrical equivalence in voltage, current, and frequency parameters. The UMT1NFHATN includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring enhanced reliability standards. However, the maximum power dissipation is rated at 150mW, which is 50% lower than the original 300mW specification. This limitation restricts its use to applications where power dissipation does not exceed 150mW. The 6-TSSOP (SOT-363) package is physically smaller than the original Mini5-G3-B package and requires board layout redesign. This part is active in production with 15,906 pieces in stock.

Selection Criteria:

• Use IMT1AT110 for direct replacement in existing designs with minimal layout changes and full 300mW power budget
• Use UMT1NFHATN only when automotive qualification is required and power dissipation is confirmed below 150mW
• Both parts are RoHS3 compliant and MSL 1 rated, ensuring regulatory and handling compatibility with the original specification

Frequently Asked Questions (FAQ)

Q: Can the IMT1AT110 directly replace the DMA201010R without circuit modification?

A: The IMT1AT110 is electrically equivalent across all critical parameters (50V breakdown voltage, 100mA+ collector current, 300mW power, 150MHz transition frequency). The SC-74 package is mechanically similar to the original SC-74A package. Board layout verification is required to confirm pin-to-pin compatibility and trace routing feasibility, but no circuit modification is necessary.

Q: What is the key difference between IMT1AT110 and UMT1NFHATN?

A: Both parts share identical electrical specifications for voltage, current, and frequency. The primary difference is power dissipation: IMT1AT110 is rated at 300mW (matching the original), while UMT1NFHATN is rated at 150mW. Additionally, UMT1NFHATN includes automotive-grade qualification (AEC-Q101) and uses a smaller 6-TSSOP package. Select IMT1AT110 for applications requiring full 300mW power budget; select UMT1NFHATN only when power dissipation is confirmed below 150mW and automotive qualification is required.

Q: Are there package compatibility concerns with these substitutes?

A: The DMA201010R uses a Mini5-G3-B package (SC-74A, SOT-753). The IMT1AT110 uses SC-74 (SOT-457), which is mechanically similar and typically compatible with existing footprints. The UMT1NFHATN uses 6-TSSOP (SOT-363), which is physically smaller and requires board layout redesign. Verify footprint compatibility with your PCB design before component selection.

Q: Do these substitutes meet RoHS and environmental compliance requirements?

A: Yes. Both IMT1AT110 and UMT1NFHATN are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the environmental compliance profile of the original DMA201010R. Both parts are suitable for applications with equivalent regulatory requirements.

Q: What is the inventory status of these substitutes?

A: The DMA201010R is discontinued at DiGi Electronics with no ongoing production. IMT1AT110 is in active production with 125,200 pieces in stock. UMT1NFHATN is in active production with 15,906 pieces in stock. Both substitutes offer reliable long-term availability for production requirements.

Q: Can UMT1NFHATN be used in all applications where DMA201010R was used?

A: UMT1NFHATN is electrically equivalent for voltage, current, and frequency specifications. However, its 150mW power rating is 50% lower than the original 300mW specification. Use UMT1NFHATN only in applications where actual power dissipation does not exceed 150mW. For applications requiring the full 300mW power budget, use IMT1AT110.
