DKI03082 Equivalent & Substitute Parts Engineering Reference

Part Overview

The Sanken Electric USA Inc. DKI03082 is an obsolete N-Channel MOSFET in the Transistors, FETs, MOSFETs category. It is provided in surface mount TO-252 packaging and features a Drain to Source Voltage (Vdss) of 30 V, continuous drain current (Id) of 29A (Tc), and power dissipation of 32W (Tc). As this component is now discontinued (Obsolete product status), it is necessary to identify substitute models with compatible electrical characteristics and package types for continued design support or maintenance of existing assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute components are selected strictly according to matching key electrical and mechanical parameters. For the DKI03082, the criteria for equivalency are:

• N-Channel MOSFET Type
• Drain to Source Voltage (Vdss) of 30 V
• Drive Voltage of 4.5V, 10V for Rds On values
• Gate Threshold Voltage (Vgs(th)) maximum of 2.5V @ 250µA
• Rds On value is comparable at specified Id and Vgs
• Package compatibility: TO-252, TO-252-3, DPAK (2 Leads + Tab), SC-63
• Compliance: RoHS and MSL ratings

Substitute selection is strictly determined by these provided parameters. Parts meeting these exact criteria are included as eligible alternatives.

Parameter Comparison

Engineering Selection Recommendations

For the discontinued DKI03082 MOSFET, substitute selection requires an exact match on product status, compliance, and certifications. The FDD8876 from onsemi is also marked as Obsolete, includes ROHS3 compliance, MSL: 1, and shares identical ECCN and HTSUS codes. Both components meet RoHS compliance and unlimited moisture sensitivity level, ensuring consistency with environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting substitute MOSFETs in this category?
A1: Key electrical and mechanical parameters include FET type, drain to source voltage, current rating, drive voltage, Rds On, gate threshold voltage, package type, compliance status (RoHS), and moisture sensitivity level.

Q2: Is package compatibility mandatory for substitution?
A2: Yes. Substitute MOSFETs must share the same package/case specifications, namely TO-252-3, DPAK (2 Leads + Tab), SC-63, to ensure drop-in physical and electrical replacement.

Q3: How do product status and compliance affect substitution eligibility?
A3: Only parts labeled as Obsolete and with matching compliance status (such as RoHS and MSL ratings) are considered direct substitutes, per the provided parameters.

Q4: Can the substitute’s electrical performance parameters differ from the main part?
A4: Substitution is allowed only when core electrical parameters (Vdss, Id, Rds On, Vgs(th)) and drive requirements are equivalent, as established in the comparison table.

Q5: Are there moisture sensitivity considerations for these MOSFETs?
A5: Both main and substitute components feature MSL: 1 (Unlimited), which is required for direct substitution in environmental and storage handling contexts.
