FDMC8588DC N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The FDMC8588DC is an N-Channel MOSFET manufactured by onsemi, rated for 25V drain-to-source voltage and 40A continuous drain current. This device is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, production continuity, and component sourcing. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1) and is not subject to REACH restrictions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDMC8588DC is determined by alignment of the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): 25V minimum
• Continuous Drain Current (Id) @ 25°C: 40A minimum
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The three substitute parts identified—CSD16342Q5A, CSD16404Q5A, and DMN2005UPS-13—meet or exceed the voltage and current ratings of the FDMC8588DC. All substitutes are active products from established manufacturers (Texas Instruments and Diodes Incorporated), ensuring long-term availability and design support. Each substitute maintains RoHS3 compliance and MSL 1 rating, supporting equivalent environmental and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

CSD16342Q5A (Texas Instruments NexFET™ Series)

This substitute provides the highest current rating at 100A (Tc), exceeding the FDMC8588DC specification by 2.5x. The device maintains 25V Vdss rating and is classified as an active product with full manufacturer support. RoHS3 compliance and MSL 1 rating align with the original part. REACH status is affected, requiring verification against supply chain requirements. The 8-PowerTDFN package is standard for this device class.

CSD16404Q5A (Texas Instruments NexFET™ Series)

This substitute offers 81A (Tc) continuous drain current, exceeding the FDMC8588DC by 2x. The 25V Vdss rating matches the original specification. Product status is active with established manufacturer support. RoHS3 compliance and MSL 1 rating are equivalent to the main part. REACH status is unaffected, supporting unrestricted supply chain integration. The 8-PowerTDFN package is standard for this device class.

DMN2005UPS-13 (Diodes Incorporated PowerDI5060 Series)

This substitute provides 100A (Tc) continuous drain current, matching the performance of CSD16342Q5A. The Vdss rating is 20V, which is 5V lower than the FDMC8588DC specification. This part is suitable for applications where the 25V rating is not a critical requirement. Product status is active with full manufacturer support. RoHS3 compliance and MSL 1 rating are equivalent. REACH status is unaffected. The 8-PowerTDFN package is standard for this device class.

Frequently Asked Questions (FAQ)

Q: Can CSD16342Q5A directly replace FDMC8588DC in all applications?

A: CSD16342Q5A meets or exceeds all critical electrical parameters of the FDMC8588DC, including 25V Vdss and 40A continuous drain current. Both devices use the 8-PowerTDFN package. Substitution is valid for applications where REACH compliance is not a constraint. Verify REACH requirements against your supply chain specifications.

Q: What is the key difference between CSD16404Q5A and CSD16342Q5A?

A: Both devices are Texas Instruments NexFET™ series MOSFETs with 25V Vdss rating. CSD16342Q5A provides 100A (Tc) continuous drain current, while CSD16404Q5A provides 81A (Tc). CSD16404Q5A has REACH unaffected status, whereas CSD16342Q5A is REACH affected. Select based on current requirements and supply chain REACH compliance needs.

Q: Why is DMN2005UPS-13 listed as a substitute if it has only 20V Vdss?

A: DMN2005UPS-13 is included as a substitute because it meets the 40A continuous drain current requirement and exceeds it significantly at 100A (Tc). The 20V Vdss rating is lower than the FDMC8588DC 25V specification. This part is suitable for applications operating at 20V or below. For applications requiring the full 25V rating, select CSD16342Q5A or CSD16404Q5A.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. FDMC8588DC, CSD16342Q5A, CSD16404Q5A, and DMN2005UPS-13 are all RoHS3 compliant. All devices have MSL 1 (Unlimited) moisture sensitivity level, supporting equivalent handling and storage requirements.

Q: What is the package compatibility between the main part and substitutes?

A: The FDMC8588DC package designation is not specified in the available data. All three substitute parts use the 8-PowerTDFN package (8-VSONP 5x6 form factor). Verify PCB footprint compatibility with your design before implementation.

Q: Which substitute should I select for new designs?

A: For new designs, select based on current requirements and supply chain constraints. CSD16404Q5A is recommended for applications requiring 25V Vdss with REACH unaffected status and active product support. CSD16342Q5A is suitable where REACH affected status is acceptable. DMN2005UPS-13 is appropriate for 20V applications with high current requirements.
