Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIMD10A-7-F is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Transistor configuration: 1 NPN, 1 PNP pre-biased dual transistor
• Maximum collector current: 100mA minimum (MIMD10A-7-F supports 100mA and 500mA)
• Collector-emitter breakdown voltage: 50V
• DC current gain (hFE): 100 @ 1mA, 5V
• Package type: SOT-363 / 6-TSSOP surface mount

Mechanical Compatibility Requirements:

• Surface mount package: 6-TSSOP / SOT-363
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS3 compliance

The substitute parts PUMD14,115 and PUMD19,115 meet these core requirements. Both are active products from Nexperia USA Inc. with identical package specifications, voltage ratings, and current gain characteristics. The primary difference between substitutes lies in the base resistor (R1) configuration: PUMD14,115 features 47kOhms while PUMD19,115 features 22kOhms. Selection between these substitutes depends on the specific biasing network requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

PUMD14,115 and PUMD19,115 Selection Criteria:

Both substitute parts are active products with AEC-Q100 automotive qualification and ROHS3 compliance, providing superior long-term availability compared to the obsolete MIMD10A-7-F. The electrical parameters align with the main part across voltage, current gain, and package specifications.

Selection between PUMD14,115 and PUMD19,115 depends on base resistor requirements:

PUMD14,115 features a 47kOhms base resistor (R1), suitable for applications requiring higher input impedance and reduced base current drive.

PUMD19,115 features a 22kOhms base resistor (R1), suitable for applications requiring lower input impedance and increased base current drive capability.

Both substitutes provide improved saturation voltage performance (150mV versus 300mV) and higher maximum power dissipation (300mW versus 200mW) compared to the main part, offering enhanced thermal margin in power-sensitive applications.

The automotive qualification and AEC-Q100 certification of both substitutes provide additional reliability assurance for mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can PUMD14,115 and PUMD19,115 be used interchangeably with MIMD10A-7-F?

A: Both parts share identical package specifications (SOT-363 / 6-TSSOP), voltage ratings (50V), current ratings (100mA), and DC current gain characteristics (100 @ 1mA, 5V). However, the base resistor values differ (47kOhms for PUMD14,115 and 22kOhms for PUMD19,115 versus 100Ohms and 10kOhms for MIMD10A-7-F). Circuit validation is required to confirm compatibility with the specific biasing network design.

Q: What is the primary difference between PUMD14,115 and PUMD19,115?

A: The primary difference is the base resistor (R1) value. PUMD14,115 incorporates 47kOhms while PUMD19,115 incorporates 22kOhms. This affects the input impedance and base current drive characteristics. Selection depends on the application's biasing requirements.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both PUMD14,115 and PUMD19,115 carry automotive grade designation and AEC-Q100 qualification, making them suitable for automotive and mission-critical applications.

Q: What are the package compatibility considerations?

A: All parts (MIMD10A-7-F, PUMD14,115, and PUMD19,115) use the 6-TSSOP / SOT-363 surface mount package. PCB footprints are compatible. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, requiring no special handling precautions.

Q: How do the electrical performance characteristics compare?

A: The substitute parts provide improved saturation voltage (150mV versus 300mV) and higher maximum power dissipation (300mW versus 200mW). Collector cutoff current is slightly higher (1µA versus 500nA). These differences represent improved performance margins in most applications.

Q: What is the availability status of these parts?

A: MIMD10A-7-F is obsolete. PUMD14,115 and PUMD19,115 are active products with current inventory availability, ensuring long-term supply chain continuity.
