Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F3923CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (392 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly. Operating temperature range (-55°C ~ 155°C) must be maintained or exceeded.

Mechanical Compatibility: Package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and number of terminations (2) must be identical to ensure PCB footprint compatibility.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL 1 rating. REACH unaffected status and EAR99 ECCN classification apply uniformly across all qualified substitutes.

Composition & Features: Thick film construction is required. Moisture-resistant or automotive AEC-Q200 rated variants are acceptable as they meet or exceed the base moisture-resistant specification.

All four substitute parts listed meet these criteria and are direct functional equivalents for circuit applications requiring the RC2012F3923CS.
