Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03J1R8V is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (1.8 Ohms), tolerance (±5%), and power rating (0.1W) must be identical. Temperature coefficient range (-100 / +600 ppm/°C) and operating temperature limits (-55°C ~ 155°C) establish the thermal performance envelope.

Mechanical Compatibility: Package designation (0603 / 1608 Metric), physical dimensions (0.063" L x 0.031" W), and maximum seated height (0.022") ensure PCB footprint and assembly process compatibility.

Automotive & Compliance Requirements: AEC-Q200 automotive qualification, anti-sulfur composition, RoHS3 compliance, and MSL 1 rating are mandatory for direct substitution in regulated applications.

Composition & Construction: Thick film construction type must match to maintain electrical performance characteristics and reliability profiles.

Substitute parts meeting all these parameters are electrically and mechanically interchangeable without circuit redesign or assembly process modification.
