FDS8874 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The FDS8874 is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 16A continuous drain current at 25°C. This device is housed in an 8-SOIC surface mount package and is part of the PowerTrench® series. The FDS8874 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and component sourcing.

Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, on-resistance characteristics, and thermal performance while accommodating packaging variations in the 8-pin surface mount family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FDS8874 is determined by the following critical parameters:

Mandatory Electrical Compatibility:

• Drain-to-Source Voltage (Vdss): 30 V minimum
• Continuous Drain Current (Id): 16 A minimum at 25°C
• Power Dissipation: 2.5 W minimum
• Operating Temperature Range: Must encompass -55°C to 150°C or equivalent thermal envelope
• Gate-Source Voltage (Vgs): ±20 V maximum rating

Package and Mounting Compatibility:

• Surface mount configuration required
• 8-pin package family (8-SOIC, 8-SOP, 8-SO, 8-DSO variants acceptable)
• Pin-to-pin compatibility or functional equivalence in target application

Compliance and Status:

• Active product status preferred for new designs; Not For New Designs acceptable for legacy support
• RoHS3 compliance preferred where available
• REACH Unaffected status maintained across all substitutes

The following parts meet these criteria and are grouped as direct or similar substitutes based on electrical parameter alignment and packaging compatibility.

Parameter Comparison

Engineering Selection Recommendations

HAT2197R-EL-E (Renesas Electronics Corporation)

This part is recommended as a primary substitute for new designs. It maintains identical voltage and current ratings (30V, 16A) with matching power dissipation (2.5W). The device is in active product status with ROHS3 compliance and unlimited moisture sensitivity level. The 8-SOP package is functionally compatible with the original 8-SOIC footprint in most applications. On-resistance specification at 8A (6.7 mOhm) is slightly higher than the FDS8874 at 16A, requiring thermal analysis in high-current applications.

IRF8736TRPBF (Infineon Technologies)

This part is suitable as a substitute with enhanced performance characteristics. It exceeds the original specification with 18A continuous drain current versus 16A, while maintaining the 30V voltage rating and 2.5W power dissipation. The device features lower on-resistance (4.8 mOhm @ 18A, 10V) and reduced gate charge (26 nC @ 4.5V), resulting in improved switching efficiency. Active product status, ROHS3 compliance, and unlimited MSL rating support production continuity. The 8-SO package is compatible with the original 8-SOIC pinout.

DMN3010LSS-13 (Diodes Incorporated)

This part qualifies as a substitute with full electrical compatibility. It maintains 30V/16A ratings and 2.5W power dissipation with active product status and ROHS3 compliance. The 8-SOP package is functionally equivalent to the original 8-SOIC. On-resistance is specified at 9.0 mOhm @ 16A, 10V, which is higher than the FDS8874 and requires thermal verification in continuous high-current operation. Unlimited MSL rating supports standard manufacturing environments.

BSO040N03MSGXUMA1 (Infineon Technologies)

This part is acceptable for legacy system support only. Although it meets the 30V/16A electrical requirements, it carries a "Not For New Designs" product status designation. The device features superior on-resistance (4.0 mOhm @ 20A, 10V) and lower power dissipation (1.56W), but the MSL rating of 3 (168 hours) requires controlled moisture handling during assembly. The PG-DSO-8 package is compatible with the original 8-SOIC footprint. This part is suitable for replacement in existing production lines where design changes are not feasible.

Frequently Asked Questions (FAQ)

Q: Can the HAT2197R-EL-E replace the FDS8874 in all applications?

A: The HAT2197R-EL-E maintains electrical compatibility across voltage (30V), current (16A), and power dissipation (2.5W) specifications. The 8-SOP package is functionally equivalent to the original 8-SOIC in standard PCB layouts. However, on-resistance is specified at a lower current level (8A vs. 16A), requiring thermal analysis in applications operating continuously at maximum rated current.

Q: What is the difference between 8-SOIC, 8-SOP, and 8-SO packages?

A: These are all 8-pin surface mount packages with identical 0.154" (3.90mm) body width and compatible pinouts for MOSFET applications. The designations reflect minor variations in lead geometry and pitch specifications among manufacturers. Pin-to-pin compatibility is maintained across these variants for standard switching applications.

Q: Why is the IRF8736TRPBF rated for 18A when the FDS8874 is rated for 16A?

A: The IRF8736TRPBF has a higher continuous drain current rating due to superior thermal characteristics and lower on-resistance. This device can be used as a direct substitute in FDS8874 applications without derating. The enhanced current capability provides design margin and improved efficiency.

Q: Is the BSO040N03MSGXUMA1 suitable for new product designs?

A: No. The BSO040N03MSGXUMA1 carries a "Not For New Designs" product status. It is appropriate only for replacement in existing production lines or legacy system support where design changes are not feasible. For new designs, select HAT2197R-EL-E, DMN3010LSS-13, or IRF8736TRPBF.

Q: What does MSL rating mean, and why does BSO040N03MSGXUMA1 have MSL 3?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before assembly. MSL 1 (unlimited) allows indefinite storage without special handling. MSL 3 (168 hours) requires controlled moisture environments and baking before reflow soldering. The FDS8874, HAT2197R-EL-E, DMN3010LSS-13, and IRF8736TRPBF all have MSL 1, simplifying supply chain management.

Q: How do I verify on-resistance compatibility when specifications are measured at different current levels?

A: On-resistance varies with gate-source voltage and drain current. Compare specifications at the same Vgs (typically 10V) and at or near your application's operating current. The FDS8874 specifies 5.5 mOhm @ 16A, 10V. The IRF8736TRPBF specifies 4.8 mOhm @ 18A, 10V, indicating superior performance. The DMN3010LSS-13 specifies 9.0 mOhm @ 16A, 10V, which is higher and requires thermal analysis.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts (HAT2197R-EL-E, IRF8736TRPBF, DMN3010LSS-13) are ROHS3 compliant. The BSO040N03MSGXUMA1 is also ROHS3 compliant. The original FDS8874 does not specify RoHS status, which is typical for obsolete components.

Q: Can I use these substitutes interchangeably in my PCB layout?

A: The 8-pin surface mount packages (8-SOIC, 8-SOP, 8-SO, 8-DSO) share compatible pinouts and body dimensions. However, verify lead spacing and solder pad geometry with your PCB design software. Minor footprint adjustments may be required depending on your original design specifications and manufacturing tolerances.
