Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMA9610F0R is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor configuration: 2 PNP - Pre-Biased (Dual)
• Maximum collector current: 100 mA
• Maximum collector-emitter breakdown voltage: 50 V
• Base resistor (R1): 4.7 kOhms
• Surface mount technology with compatible package footprint
• RoHS compliance status

Allowable Variations:

• Emitter-base resistor (R2) may differ from the specified 10 kOhms value
• DC current gain (hFE) specifications may vary
• Saturation voltage (Vce) may differ within acceptable operating margins
• Transition frequency may be present in substitute parts
• Power dissipation rating may be lower than the original 125 mW specification
• Package designation may differ (SOT-553 vs. SOT-665) provided pin configuration and footprint compatibility are maintained

The RN2706JE(TE85L,F) from Toshiba Semiconductor and Storage qualifies as a substitute based on matching transistor type, collector current rating, breakdown voltage, and base resistor value.

Engineering Selection Recommendations

Primary Substitute: RN2706JE(TE85L,F)

The RN2706JE(TE85L,F) from Toshiba Semiconductor and Storage is the qualified substitute for the discontinued DMA9610F0R. This selection is based on the following engineering criteria:

Electrical Compatibility:

• Identical maximum collector current rating (100 mA)
• Identical maximum collector-emitter breakdown voltage (50 V)
• Identical base resistor value (R1 = 4.7 kOhms)
• Dual PNP pre-biased transistor configuration maintained

Compliance and Availability:

• Active product status with 4167 pieces in stock inventory
• ROHS3 compliance exceeds RoHS Compliant requirement
• Moisture sensitivity level MSL 1 (Unlimited) matches original specification
• Identical ECCN and HTSUS classifications

Design Considerations:

• Emitter-base resistor differs (47 kOhms vs. 10 kOhms); circuit biasing characteristics will be affected
• Power dissipation rating is lower (100 mW vs. 125 mW); verify thermal requirements in target application
• Package footprint differs (SOT-553 vs. SOT-665); PCB layout modification required
• Higher DC current gain (80 vs. 30) and lower collector cutoff current (100 nA vs. 500 nA) indicate improved performance characteristics
• Transition frequency specification (200 MHz) available in substitute part

Substitution is electrically valid for applications where the modified biasing resistor network and reduced power rating are acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can the RN2706JE(TE85L,F) be used as a direct drop-in replacement for the DMA9610F0R?

A: No. While the RN2706JE(TE85L,F) is electrically compatible in terms of transistor type, collector current, and breakdown voltage, it is not a direct drop-in replacement. The different emitter-base resistor value (47 kOhms vs. 10 kOhms) will alter circuit biasing behavior. Additionally, the package footprint differs (SOT-553 vs. SOT-665), requiring PCB layout modification.

Q: What is the impact of the different emitter-base resistor value?

A: The RN2706JE(TE85L,F) has an emitter-base resistor of 47 kOhms compared to 10 kOhms in the DMA9610F0R. This higher resistance value reduces base current and affects the transistor's switching speed and saturation characteristics. Circuit performance will differ; design verification is necessary for the target application.

Q: Are both parts RoHS compliant?

A: Yes. The DMA9610F0R is RoHS Compliant, and the RN2706JE(TE85L,F) is ROHS3 Compliant. Both meet RoHS requirements, with the Toshiba part meeting the more recent ROHS3 standard.

Q: What is the difference in package types?

A: The DMA9610F0R uses SOT-665 package, while the RN2706JE(TE85L,F) uses SOT-553 package. Both are surface mount packages for dual PNP pre-biased transistors, but the physical dimensions and pin layouts differ. PCB footprint modification is required for substitution.

Q: Does the lower power rating of the RN2706JE(TE85L,F) affect substitution?

A: The RN2706JE(TE85L,F) has a maximum power rating of 100 mW compared to 125 mW for the DMA9610F0R. If the original application operates near the 125 mW limit, the substitute part may have insufficient thermal headroom. Verify power dissipation in the target circuit.

Q: What is the significance of the transition frequency specification in the substitute part?

A: The RN2706JE(TE85L,F) specifies a transition frequency of 200 MHz, indicating higher-frequency capability. The DMA9610F0R does not specify this parameter. This difference suggests the Toshiba part may have improved high-frequency performance, which is beneficial for high-speed switching applications.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating identical moisture handling and storage requirements.

Q: What inventory status should influence the substitution decision?

A: The DMA9610F0R is discontinued at DiGi Electronics with 1056 pieces in stock. The RN2706JE(TE85L,F) is an active product with 4167 pieces in stock, providing superior long-term availability and supply chain security for production designs.
