SP8K1FRATB Equivalent & Substitute Parts Reference

Part Overview

Rohm Semiconductor SP8K1FRATB is a MOSFET array device categorized under Transistors, FETs, MOSFETs with dual N-Channel configuration rated at 30V and 5A (Ta) continuous drain current, housed in a surface mount 8-SOP (8-SOIC, 0.154", 3.90mm width) package. The part features a low maximum Rds(On) of 51mOhm @ 5A, 10V, an automotive grade rating with AEC-Q101 qualification, and is RoHS3 compliant. It is active in production with inventory currently available.

Identification of alternative models or substitute parts is necessary to ensure supply flexibility, minimize production downtime in case of part shortages, and provide direct replacement options for compliant, footprint-compatible devices. Substitutes must comply with identical voltage, package, grade, and qualification features for strict engineering equivalency.
