• Physical Dimensions: Must be 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Composition: Must be Metal Film
• Operating Temperature Range: Must support -65°C to 175°C
• Series Compliance: Must conform to MIL-R-10509/7 military specification
• Features: Must include Flame Retardant Coating, Military rating, Moisture Resistant, and Safety construction

Tolerance and temperature coefficient variations are permitted substitution parameters when the above core electrical and mechanical specifications are maintained. The identified substitute parts meet all mandatory compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

RN55D2000FB14 (Parametric Equivalent): This part maintains identical electrical specifications to the RN55D2000FBSL, including ±1% tolerance and ±100ppm/°C temperature coefficient. Both parts are active products with full military compliance to MIL-R-10509/7. Selection of RN55D2000FB14 is appropriate when inventory of the primary part number is constrained or when procurement lead times require alternative sourcing within the same specification class.

RN55C2000BB14 (Upgrade Substitute): This part provides enhanced tolerance performance at ±0.1% and improved temperature stability at ±50ppm/°C while maintaining all other electrical and mechanical specifications. The RN55C2000BB14 is suitable for applications requiring tighter tolerance control or superior temperature coefficient performance. This part is active and maintains full military compliance. Higher inventory availability (2,700 units) supports extended procurement windows.

Both substitute parts are RoHS non-compliant and REACH Affected, matching the compliance status of the main part number. All three parts are rated for the same operating temperature range and feature identical physical dimensions and axial package configuration.

Frequently Asked Questions (FAQ)

Q: Can RN55D2000FB14 be used as a direct replacement for RN55D2000FBSL?

A: Yes. RN55D2000FB14 is a parametric equivalent with identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. Both parts conform to MIL-R-10509/7 military specification and feature the same flame retardant, moisture-resistant construction. No circuit redesign or re-qualification is required.

Q: What is the primary difference between RN55C2000BB14 and the main part number?

A: RN55C2000BB14 offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). All other parameters, including resistance value, power rating, package type, and operating temperature range, remain identical. Selection depends on application tolerance requirements.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.090" Dia × 0.240" L) and axial package configuration, enabling direct mechanical substitution on printed circuit boards without layout modifications.

Q: Do the substitute parts maintain military specification compliance?

A: Yes. Both RN55D2000FB14 and RN55C2000BB14 are qualified to MIL-R-10509/7 military specification and feature flame retardant coating, moisture resistance, and safety-rated construction identical to the main part number.

Q: Which substitute part should be selected for improved circuit accuracy?

A: RN55C2000BB14 provides superior accuracy through ±0.1% tolerance and ±50ppm/°C temperature coefficient, compared to ±1% tolerance and ±100ppm/°C for the main part. Selection should be based on circuit tolerance stack-up analysis and application requirements.
