• Package Type: Must be Axial
• Physical Dimensions: Must be 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Series Compliance: Must belong to RN55 military series with MIL-R-10509/7 certification
• Composition: Must be Metal Film
• Operating Temperature Range: Must support -65°C to 175°C

Tolerance and temperature coefficient may vary within acceptable ranges for equivalent substitution. The identified substitute parts meet all mandatory parameters while offering either equivalent or improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

RN55E2001BB14 (Upgrade Option): This substitute provides improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). All other electrical and mechanical parameters remain equivalent. This part is suitable for applications requiring tighter tolerance control and enhanced temperature stability while maintaining full military compliance and certification.

RN55C2001FB14 (Parametric Equivalent): This substitute maintains identical tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications as the main part. All electrical and mechanical characteristics are equivalent. This part is suitable for direct replacement in applications where the original specifications are required.

Both substitute parts are active products with confirmed inventory availability and maintain full compliance with MIL-R-10509/7 military standards, RoHS non-compliance status, and REACH affected designation consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55C2001FBSL?

A: Yes. RN55E2001BB14 meets all mandatory substitution criteria: identical resistance value, power rating, package type, physical dimensions, and military series compliance. The improved tolerance (±0.1%) and temperature coefficient (±25ppm/°C) represent enhanced performance characteristics suitable for the same application space.

Q: What is the difference between RN55C2001FB14 and RN55C2001FBSL?

A: Both parts share identical electrical specifications: 2 kOhms ±1% tolerance, 0.125W power rating, ±50ppm/°C temperature coefficient, and -65°C to 175°C operating range. Physical dimensions, package type, and military certification are equivalent. The parts are parametrically equivalent for component selection purposes.

Q: Are all substitute parts available in the same axial package?

A: Yes. All listed substitute parts are supplied in axial package configuration with dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm), ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: Do the substitute parts maintain military compliance?

A: Yes. Both RN55E2001BB14 and RN55C2001FB14 are certified to MIL-R-10509/7 military standards and belong to the RN55 military series. All parts maintain identical compliance status, RoHS non-compliance designation, and REACH affected classification.

Q: Which substitute should be selected for temperature-sensitive applications?

A: RN55E2001BB14 is the appropriate selection for temperature-sensitive applications due to its lower temperature coefficient of ±25ppm/°C compared to ±50ppm/°C for the main part and RN55C2001FB14.
