Equivalent & Substitute Parts for DMC904010R

Part Overview

The Panasonic DMC904010R is a dual NPN bipolar junction transistor array designed for general-purpose switching and amplification applications. This component features a 50V collector-emitter breakdown voltage rating, 100mA maximum collector current, and 150MHz transition frequency in a surface mount SSMini6-F3-B package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC904010R is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Transistor configuration: 2 NPN (Dual) array
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Surface mount technology
• Package compatibility: SOT-563 or SOT-666
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Acceptable Parameter Variations:

• Vce saturation may exceed the original specification if the substitute part demonstrates lower saturation voltage
• Power dissipation rating may exceed the original 125mW specification
• Transition frequency may exceed 150MHz
• Operating temperature range may be broader than the original specification
• DC current gain (hFE) values may differ provided the part functions within the specified voltage and current ranges

The three substitute parts identified—EMX1DXV6T1G, EMX1DXV6T5G, and EMX52T2R—satisfy all mandatory equivalence criteria and are therefore suitable for direct replacement in applications designed for the DMC904010R.

Engineering Selection Recommendations

EMX1DXV6T1G (onsemi) - Primary Substitute

The EMX1DXV6T1G is the recommended primary substitute for the DMC904010R. This part maintains full electrical equivalence across all critical parameters: 100mA collector current, 50V breakdown voltage, and dual NPN configuration. The part carries Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance exceeds the original RoHS requirement. The 500mW power rating and 180MHz transition frequency provide performance headroom beyond the original specification. Packaging is SOT-563 with Tape & Reel (TR) delivery format.

EMX52T2R (Rohm Semiconductor) - Secondary Substitute

The EMX52T2R serves as an alternative substitute with Active product status and superior performance characteristics. This part matches all mandatory electrical parameters while offering a 350MHz transition frequency and 150mW power rating that closely aligns with the original DMC904010R specifications. The EMT6 package format is compatible with SOT-563 and SOT-666 footprints. ROHS3 compliance and MSL 1 rating are maintained. Cut Tape (CT) & Digi-Reel® packaging is available.

EMX1DXV6T5G (onsemi) - Tertiary Substitute

The EMX1DXV6T5G provides electrical equivalence identical to the EMX1DXV6T1G but carries Obsolete product status. This part is suitable only for applications where long-term supply continuity is not a requirement. Electrical parameters, compliance certifications, and package compatibility are equivalent to the EMX1DXV6T1G. Cut Tape (CT) & Digi-Reel® packaging format is available.

Frequently Asked Questions (FAQ)

Q: Can the EMX1DXV6T1G directly replace the DMC904010R without circuit modification?

A: Yes. The EMX1DXV6T1G maintains electrical equivalence across all critical parameters: 100mA maximum collector current, 50V collector-emitter breakdown voltage, dual NPN configuration, and compatible SOT-563/SOT-666 packaging. The higher power rating (500mW vs. 125mW) and increased transition frequency (180MHz vs. 150MHz) provide performance margin without requiring circuit changes.

Q: What is the difference between the EMX1DXV6T1G and EMX1DXV6T5G?

A: Both parts are electrically identical with matching specifications for collector current, breakdown voltage, saturation voltage, and transition frequency. The primary difference is product status: EMX1DXV6T1G is Active, while EMX1DXV6T5G is Obsolete. For new designs and long-term production, EMX1DXV6T1G is the appropriate selection.

Q: Is the EMX52T2R package compatible with the original DMC904010R footprint?

A: Yes. The EMX52T2R uses the EMT6 package format, which is compatible with SOT-563 and SOT-666 footprints specified for the DMC904010R. Surface mount placement and reflow soldering procedures remain unchanged.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All three substitute parts carry ROHS3 compliance certification, which exceeds the original RoHS Compliant status of the DMC904010R. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: Which substitute part offers the best performance for high-frequency applications?

A: The EMX52T2R provides the highest transition frequency at 350MHz, compared to 180MHz for the onsemi parts and 150MHz for the original DMC904010R. This part is suitable for applications requiring extended frequency response.

Q: Are there any differences in saturation voltage between the substitutes and the original part?

A: Yes. The DMC904010R specifies 300mV saturation voltage at 10mA/100mA. The onsemi parts (EMX1DXV6T1G and EMX1DXV6T5G) specify 400mV at 5mA/50mA, while the EMX52T2R specifies 300mV at 5mA/50mA. These differences are within acceptable ranges for switching applications and do not require circuit modification.

Q: What packaging formats are available for each substitute part?

A: EMX1DXV6T1G is supplied in Tape & Reel (TR) format. EMX1DXV6T5G and EMX52T2R are supplied in Cut Tape (CT) & Digi-Reel® format. All parts are surface mount with compatible SOT-563/SOT-666 footprints.
