Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C1003CBSL is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 100 kOhms (exact match required)
• Power rating: 0.5W minimum (1/2W)
• Package type: Axial configuration
• Operating temperature range: -65°C to 175°C minimum
• Composition: Metal film construction
• Series compliance: Military-grade RN65 series (MIL-R-10509/2)

Secondary Compatibility Parameters:

• Tolerance: ±0.25% or tighter (lower tolerance values are acceptable upgrades)
• Temperature coefficient: ±50ppm/°C or lower (lower values indicate improved stability)
• Physical dimensions: 0.180" Dia × 0.562" L (identical footprint required)
• Termination count: 2 (axial leads)

The RN65E1003BB14 qualifies as a direct substitute because it maintains all primary criteria while offering improved tolerance (±0.1% versus ±0.25%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison
