Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F3483V is determined by strict equivalence across the following parameters:

Resistance value: 348 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W / 1/4W (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
Termination count: 2 (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All qualified substitutes meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package tolerance, feature sets (anti-sulfur, moisture resistant, automotive certification), and product status do not affect functional interchangeability in circuit applications.
