Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4532FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 45.3 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product status or certifications do not affect functional substitutability for standard applications.
