Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C2001CB14 is determined by the following critical parameters:

• Resistance Value: Must be 2 kOhms (exact match required)
• Power Rating: Must be 0.125W minimum (1/8W or higher acceptable)
• Package Type: Must be Axial (mechanical and electrical interface requirement)
• Composition: Must be Metal Film (electrical performance characteristic)
• Operating Temperature Range: Must encompass -65°C to 175°C minimum
• Series Compliance: Must conform to MIL-R-10509/7 military specification
• Tolerance: May be equal to or tighter than ±0.25% (lower tolerance values represent performance enhancement)
• Temperature Coefficient: May be equal to or lower than ±50ppm/°C (lower values represent improved stability)

The RN55E2001BB14 qualifies as a direct substitute based on identical resistance, power rating, package configuration, composition, operating temperature range, and military series compliance. The substitute part offers enhanced performance through tighter tolerance (±0.1% versus ±0.25%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RN55C2001CB14 remains the specified component when tolerance of ±0.25% and temperature coefficient of ±50ppm/°C satisfy circuit design requirements. This part maintains active product status with robust inventory availability (1092 units).

RN55E2001BB14 is selected when circuit performance benefits from enhanced tolerance (±0.1%) and improved temperature stability (±25ppm/°C). Both parts share identical electrical ratings, mechanical dimensions, military compliance, and environmental protection features. Selection between these parts depends solely on tolerance and temperature coefficient requirements within the application circuit. Both parts are RoHS non-compliant and REACH-affected, with identical compliance classifications.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 replace RN55C2001CB14 in existing designs?
