Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1/2331KTB are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires exact matching of the following parameters:

• Resistance value: 330 Ohms
• Tolerance: ±10%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Composition
• Package configuration: Axial through-hole
• Physical dimensions: 0.142" Dia x 0.374" L (3.60mm x 9.50mm)
• Operating temperature range: -55°C ~ 125°C
• Termination count: 2

Parts meeting these criteria are classified as parametric equivalents and are suitable for direct substitution in applications where the RC1/2331KTB was originally specified.
