ERJ-S02F5R10X Equivalent & Substitute Parts

Part Overview

The ERJ-S02F5R10X is a 5.1 Ohm ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 0402 (1005 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and features anti-sulfur construction with AEC-Q200 automotive qualification. The part is currently in active production status with 1045 units available in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required but alternative packaging configurations, series designations, or inventory availability necessitate component alternatives.

Substitute Part Grouping Explanation

Substitution of the ERJ-S02F5R10X is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (5.1 Ohms), tolerance (±1%), and power rating (0.1W) must remain identical. Temperature coefficient (-100 / +600 ppm/°C) and operating temperature range (-55°C ~ 155°C) establish the thermal performance envelope and must not be compromised.

Mechanical Specifications: Package format (0402 / 1005 Metric), physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm), and maximum seated height (0.016" / 0.40mm) ensure PCB layout compatibility and assembly process compatibility.

Compliance & Ratings: AEC-Q200 automotive qualification, anti-sulfur construction, ROHS3 compliance, and MSL 1 rating are mandatory for equivalent substitution in automotive and high-reliability applications.

Series Designation: The ERJ-S02 and ERJ-U02 series share identical electrical and mechanical specifications. The primary distinction is packaging configuration (tape & reel availability) and inventory status.
