FDMC8015L-L701 Equivalent & Substitute Parts

Part Overview

The FDMC8015L-L701 is an N-Channel MOSFET manufactured by onsemi, part of the PowerTrench® series. This device is rated for 40V drain-to-source voltage with continuous drain current capabilities of 7A (Ta) and 18A (Tc). The component is housed in an 8-MLP (3.3x3.3) surface mount package and is designed for applications requiring efficient switching and power management in compact form factors.

The FDMC8015L-L701 carries a Last Time Buy product status, indicating that this specific part number variant is no longer in active production. This necessitates identification of equivalent substitute parts that maintain identical electrical and mechanical specifications to ensure design continuity and system compatibility.

The FDMC8015L-L701 is a specific packaging variant (tape and reel configuration designated by the -L701 suffix) of the base FDMC8015L part number. The substitute FDMC8015L maintains identical electrical specifications and package geometry while offering alternative packaging options (Cut Tape and Digi-Reel®) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The FDMC8015L is the direct parametric equivalent and recommended substitute for the FDMC8015L-L701. All electrical characteristics, thermal specifications, and mechanical dimensions are identical between the two part numbers.

Primary Advantage of Substitution: The FDMC8015L carries an Active product status, ensuring continued availability and long-term supply chain reliability. The FDMC8015L-L701 is designated Last Time Buy, indicating production discontinuation and limited remaining inventory.

Compliance Equivalence: Both parts maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is equivalent, requiring no changes to handling or storage procedures.

Packaging Consideration: The primary difference between the two part numbers is the packaging format. The FDMC8015L-L701 is supplied in tape and reel configuration (L701 designation), while the FDMC8015L is available in Cut Tape and Digi-Reel® formats. Selection between these packaging options depends on production volume and assembly equipment compatibility. Both packaging formats contain the identical die and internal construction.

Design Integration: No circuit modifications, PCB layout adjustments, or thermal management changes are required when substituting FDMC8015L for FDMC8015L-L701. The 8-PowerWDFN package geometry, pin configuration, and electrical performance are fully interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the FDMC8015L-L701 and FDMC8015L electrically identical?

A: Yes. Both parts share identical electrical specifications including Vdss (40V), continuous drain current (7A Ta / 18A Tc), on-state resistance (26 mOhm @ 7A, 10V), gate charge (19 nC @ 10V), and all other electrical parameters. They are manufactured using the same PowerTrench® technology and process.

Q: What is the difference between FDMC8015L-L701 and FDMC8015L?

A: The difference is in packaging format only. The FDMC8015L-L701 is supplied in tape and reel configuration (indicated by the -L701 suffix). The FDMC8015L is available in Cut Tape and Digi-Reel® packaging options. The die, electrical performance, and package dimensions (8-PowerWDFN 3.3x3.3) are identical.

Q: Can I use FDMC8015L in place of FDMC8015L-L701 on my PCB?

A: Yes. The FDMC8015L is a direct pin-for-pin and functionally equivalent substitute. No PCB modifications are required. The 8-PowerWDFN package footprint is identical, and all electrical characteristics match exactly.

Q: Why is FDMC8015L-L701 marked as Last Time Buy?

A: The -L701 packaging variant has been discontinued by onsemi. The base FDMC8015L part number remains in active production with alternative packaging options. Customers should transition to the FDMC8015L to ensure continued supply availability.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts have identical power dissipation ratings: 2.3W (Ta) and 24W (Tc). Thermal performance in circuit applications will be equivalent when mounted in the same package configuration.

Q: Do I need to update my component specifications if I switch to FDMC8015L?

A: No. All electrical, thermal, and mechanical specifications remain unchanged. Your design specifications, thermal calculations, and circuit analysis based on FDMC8015L-L701 are directly applicable to FDMC8015L.
