FDY100PZ Equivalent & Substitute Parts

Part Overview

The FDY100PZ is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 350mA continuous drain current at 25°C. This device is packaged in SC-89-3 (SOT-490) surface mount configuration and is part of the PowerTrench® series. The FDY100PZ is classified as obsolete, necessitating identification of equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDY100PZ are identified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• FET Type: P-Channel topology
• Drain to Source Voltage (Vdss): 20V minimum rating
• Package / Case: SC-89 or SOT-490 surface mount configuration
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS3 Compliance and MSL Level 1 classification

Secondary Compatibility Parameters:

• Continuous Drain Current (Id) at 25°C: Equal to or greater than 350mA
• On-State Resistance (Rds On): Equal to or less than 1.2Ohm @ 350mA, 4.5V
• Power Dissipation: Equal to or greater than 625mW

Substitute parts are grouped into two categories: manufacturer-recommended substitutes (active product status) and similar cross-manufacturer alternatives (active product status with equivalent electrical performance).

Parameter Comparison

Engineering Selection Recommendations

FDY102PZ (onsemi) - Manufacturer Recommended Substitute:

The FDY102PZ is the primary substitute for the obsolete FDY100PZ. Both devices are manufactured by onsemi within the PowerTrench® series and share identical voltage ratings (20V Vdss) and package configuration (SC-89-3). The FDY102PZ maintains active product status, ensuring long-term availability and supply chain continuity. The FDY102PZ provides enhanced current handling capability (830mA versus 350mA) with improved on-state resistance (500mOhm versus 1.2Ohm), delivering superior performance within the same thermal envelope (625mW). Both devices comply with ROHS3 standards and carry MSL Level 1 classification. The FDY102PZ is suitable for direct replacement in applications where the increased current capacity and reduced on-state resistance provide design margin or performance improvement.

SI1013X-T1-GE3 (Vishay Siliconix) - Cross-Manufacturer Alternative:

The SI1013X-T1-GE3 provides electrical equivalence to the FDY100PZ with identical current rating (350mA) and on-state resistance (1.2Ohm @ 350mA, 4.5V). This TrenchFET® device maintains the same voltage rating (20V Vdss), operating temperature range (-55°C to 150°C), and SC-89-3 package configuration. The SI1013X-T1-GE3 is active in production and carries ROHS3 compliance with MSL Level 1 classification. The primary distinction is reduced power dissipation rating (250mW versus 625mW), which may impose thermal constraints in high-power applications. Packaging format differs (Tape & Reel versus Cut Tape & Digi-Reel®), requiring verification of procurement and assembly compatibility. The SI1013X-T1-GE3 is suitable for applications where thermal dissipation is not a limiting factor and cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the FDY102PZ directly replace the FDY100PZ in all applications?

A: The FDY102PZ is electrically compatible with the FDY100PZ across all specified parameters. Both devices share identical voltage ratings (20V Vdss), operating temperature range (-55°C to 150°C), and SC-89-3 package configuration. The FDY102PZ provides higher current capacity (830mA versus 350mA) and lower on-state resistance (500mOhm versus 1.2Ohm), making it suitable for direct replacement. Applications operating at or below 350mA continuous drain current experience no functional change. Applications requiring higher current density benefit from improved performance characteristics.

Q: What are the key differences between the FDY102PZ and SI1013X-T1-GE3?

A: Both devices provide equivalent electrical performance at the 350mA operating point with identical on-state resistance (1.2Ohm @ 350mA, 4.5V) and voltage rating (20V Vdss). The FDY102PZ is manufactured by onsemi and supports higher power dissipation (625mW versus 250mW). The SI1013X-T1-GE3 is manufactured by Vishay Siliconix and is supplied in Tape & Reel packaging rather than Cut Tape & Digi-Reel®. Selection between these devices depends on thermal requirements, packaging format compatibility, and supplier preference.

Q: Are there packaging compatibility considerations when substituting these parts?

A: All three devices (FDY100PZ, FDY102PZ, and SI1013X-T1-GE3) use identical SC-89-3 (SOT-490) surface mount package configuration, ensuring mechanical and electrical footprint compatibility on printed circuit boards. Packaging format differs: FDY100PZ and FDY102PZ are supplied in Cut Tape (CT) & Digi-Reel® format, while SI1013X-T1-GE3 is supplied in Tape & Reel (TR) format. Verify that assembly equipment and procurement processes accommodate the selected packaging format.

Q: What compliance certifications apply to these substitute parts?

A: All three devices (FDY100PZ, FDY102PZ, and SI1013X-T1-GE3) comply with ROHS3 standards and carry Moisture Sensitivity Level (MSL) classification of 1 (Unlimited). REACH status is unaffected for all devices. ECCN classification is EAR99 for all parts. These certifications ensure regulatory compliance for commercial and industrial applications.

Q: Why is the FDY100PZ classified as obsolete?

A: The FDY100PZ is designated as obsolete by onsemi. The FDY102PZ, also manufactured by onsemi, represents the active product line continuation within the PowerTrench® series. Existing inventory of FDY100PZ remains available (29,200 pieces), but new designs should incorporate the FDY102PZ to ensure long-term supply chain continuity and access to manufacturer technical support.

Q: Can the SI1013X-T1-GE3 be used in high-power dissipation applications?

A: The SI1013X-T1-GE3 has a maximum power dissipation rating of 250mW, compared to 625mW for the FDY100PZ and FDY102PZ. Applications requiring sustained power dissipation above 250mW should use the FDY102PZ. The SI1013X-T1-GE3 is suitable for applications where power dissipation remains below 250mW or where thermal management design accommodates the lower rating.
