Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1544CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (1.54 MOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package format (1206/3216 Metric), physical dimensions, and termination count (2 terminations) must be identical to ensure PCB footprint compatibility.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), moisture resistance classification, RoHS3 compliance, and MSL rating (1) must be maintained.

Product Status: Only Active status components qualify as direct substitutes.

The identified substitute part RC1206FR-071M54L from YAGEO meets all these criteria and is classified as a direct equivalent.
