SIL03N10-TP N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The SIL03N10-TP is an N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) manufactured by Micro Commercial Co, rated for 100V drain-to-source voltage with 3A continuous drain current at 25°C. The device is housed in a SOT-23-6L surface mount package and dissipates a maximum of 1.5W. This part is classified as obsolete, making identification of active equivalent components necessary for ongoing design support, procurement continuity, and new production builds. Substitute parts must maintain electrical and mechanical compatibility across all critical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SIL03N10-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• FET Type: N-Channel topology
• Technology: MOSFET (Metal Oxide) construction
• Drain to Source Voltage (Vdss): 100V minimum rating
• Continuous Drain Current (Id): 3A minimum at 25°C
• On-State Resistance (Rds On): 120mOhm maximum at 3A, 10V gate voltage
• Power Dissipation: 1.5W maximum
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: SOT-23-6 footprint compatibility
• Supplier Device Package: SOT-23-6L

Compliance Criteria:

• RoHS3 Compliance required

The SIL03N10A-TP meets all electrical and mechanical substitution criteria. This part is manufactured by the same supplier (Micro Commercial Co), shares identical voltage and current ratings, maintains the same package footprint, and holds active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SIL03N10A-TP is the direct substitute for the obsolete SIL03N10-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical ratings, package footprint, and thermal specifications. The SIL03N10A-TP maintains active product status with current inventory availability, ensuring long-term procurement viability.

Secondary electrical parameters (Gate Threshold Voltage, Gate Charge, and Input Capacitance) show minor variations between the two parts. These variations remain within acceptable engineering tolerances for N-Channel MOSFET applications and do not compromise functional equivalence. The SIL03N10A-TP is supplied in Tape & Reel (TR) packaging, which is standard for production volume applications.

Both parts hold ROHS3 compliance certification, meeting environmental and regulatory requirements. The SIL03N10A-TP additionally carries REACH Unaffected status, providing enhanced regulatory documentation for international applications.

Frequently Asked Questions (FAQ)

Q: Can the SIL03N10A-TP be used as a direct replacement for the SIL03N10-TP in existing designs?

A: Yes. The SIL03N10A-TP is electrically and mechanically equivalent to the SIL03N10-TP. Both parts share identical voltage ratings (100V Vdss), current ratings (3A continuous drain current), on-state resistance (120mOhm @ 3A, 10V), power dissipation (1.5W), operating temperature range (-55°C to 150°C), and SOT-23-6 package footprint. No circuit modifications are required.

Q: What are the differences between the SIL03N10-TP and SIL03N10A-TP?

A: The primary difference is product status: the SIL03N10-TP is obsolete, while the SIL03N10A-TP is active with current inventory. Secondary differences include Gate Threshold Voltage (2.5V versus 3V @ 250µA), Gate Charge (19.2nC versus 26nC @ 10V), and Input Capacitance (810pF versus 1070pF @ 50V). These variations are within normal manufacturing tolerances for N-Channel MOSFETs and do not affect functional compatibility.

Q: Are there packaging differences between these parts?

A: The SIL03N10-TP packaging specification is not explicitly defined in available documentation. The SIL03N10A-TP is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production applications. Both parts use the SOT-23-6L supplier device package and SOT-23-6 case outline, ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SIL03N10-TP and SIL03N10A-TP are ROHS3 compliant. The SIL03N10A-TP additionally carries REACH Unaffected status, providing supplementary regulatory documentation for applications requiring enhanced environmental compliance verification.

Q: Why should I select the SIL03N10A-TP over the obsolete SIL03N10-TP?

A: The SIL03N10A-TP holds active product status with confirmed inventory availability (774 pieces in stock), ensuring reliable procurement for current and future production builds. The obsolete SIL03N10-TP has limited remaining inventory (953 pieces) and no manufacturer support for new orders. Transitioning to the SIL03N10A-TP eliminates supply chain risk and provides long-term design continuity.

Q: Are the thermal characteristics identical between these parts?

A: Yes. Both parts share identical maximum power dissipation (1.5W) and operating temperature range (-55°C to 150°C junction temperature). Thermal performance in equivalent circuit applications will be functionally identical.
