Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC961020R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Transistor configuration: 2 NPN - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Maximum collector-emitter breakdown voltage: 50V
• Internal base resistor (R1): 22kOhms
• Internal emitter-base resistor (R2): 22kOhms
• Maximum collector cutoff current: 500nA
• Mounting technology: Surface Mount

Mechanical Compatibility Criteria:

• Package type: SOT-665 or equivalent 6-lead SMD configuration
• Lead configuration: Flat lead surface mount

The EMG1T2R from Rohm Semiconductor satisfies all electrical equivalence criteria and maintains mechanical compatibility through its EMT5 package, which provides equivalent pinout and lead spacing for direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: EMG1T2R (Rohm Semiconductor)

The EMG1T2R is the qualified substitute for the discontinued DMC961020R based on the following factors:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. The DC current gain of 56 at 5mA, 5V is within acceptable tolerance of the original 60 at 5mA, 10V. The Vce saturation of 300mV is marginally higher than the original 250mV but remains within typical design margins for pre-biased transistor applications. The maximum power rating of 150mW exceeds the original 125mW, providing additional thermal headroom.

Regulatory Compliance: The EMG1T2R holds ROHS3 Compliant status, meeting current environmental regulations. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity classification, ensuring equivalent handling and storage requirements.

Product Status: The EMG1T2R is listed as Active with 38,548 pieces in stock, providing reliable long-term availability compared to the discontinued DMC961020R status.

Mechanical Compatibility: The EMT5 package provides equivalent pinout and lead configuration to the SSMini5-F4-B package, enabling direct board-level substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the EMG1T2R be used as a direct replacement for the DMC961020R without PCB modifications?

A: Yes. Both components use equivalent 6-lead surface mount packages with flat leads and identical pinout configurations. The EMT5 package is mechanically and electrically compatible with the SSMini5-F4-B package, permitting direct substitution on existing PCB layouts.

Q: What is the significance of the DC current gain difference (60 vs. 56)?

A: The DC current gain (hFE) difference of 4 units represents a 6.7% variance. For pre-biased transistor applications where internal resistors establish the bias point, this variance falls within typical design tolerance windows and does not affect functional performance in standard switching circuits.

Q: Does the higher Vce saturation of the EMG1T2R (300mV vs. 250mV) impact circuit performance?

A: The 50mV increase in saturation voltage is within acceptable margins for most applications. In switching circuits, this represents a 20% increase in saturation voltage but remains well below typical design thresholds. Applications requiring precise saturation characteristics should verify performance through bench testing.

Q: Are there any compliance or certification differences between the two parts?

A: The EMG1T2R carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the original part. Both components maintain identical MSL Level 1 (Unlimited) moisture sensitivity ratings and EAR99 export classification.

Q: What is the inventory status difference between these parts?

A: The DMC961020R is discontinued at DiGi Electronics with 8,400 pieces remaining in stock. The EMG1T2R is an active product with 38,548 pieces in stock, providing significantly greater availability for new designs and production requirements.

Q: Are the internal biasing resistors identical between both parts?

A: Yes. Both the DMC961020R and EMG1T2R feature identical internal biasing resistor values: 22kOhms for the base resistor (R1) and 22kOhms for the emitter-base resistor (R2). This ensures equivalent bias point establishment and circuit behavior.
