Parameter Comparison

Engineering Selection Recommendations

RN55C2003FBSL (Primary Part): Select this part for applications requiring standard ±1% tolerance with ±50ppm/°C temperature coefficient stability. The part maintains active product status with established inventory levels and full military-grade compliance per MIL-R-10509/7.

RN55E2003BB14 (Upgrade Substitute): This part provides enhanced precision with ±0.1% tolerance and improved temperature stability at ±25ppm/°C. Select this substitute when circuit design specifications demand tighter tolerance control or reduced temperature-dependent drift. All electrical and mechanical parameters remain compatible with the primary part.

RN55C2003FB14 (Parametric Equivalent): This part matches the primary specification exactly with ±1% tolerance and ±50ppm/°C temperature coefficient. Select this substitute for direct replacement when supply continuity or packaging logistics require an alternative source within identical electrical performance parameters.

All three parts maintain RoHS non-compliant status, REACH affected classification, and identical military-grade construction features. Selection between these parts depends solely on tolerance and temperature coefficient requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can RN55E2003BB14 be used as a direct replacement for RN55C2003FBSL?

A: Yes. The RN55E2003BB14 is electrically and mechanically compatible. It provides identical resistance value, power rating, package configuration, and operating temperature range. The enhanced ±0.1% tolerance and ±25ppm/°C temperature coefficient represent improved performance characteristics that do not compromise compatibility.

Q: What is the difference between RN55C2003FB14 and RN55C2003FBSL?

A: Both parts share identical electrical specifications: 200 kOhms ±1% tolerance, 0.125W power rating, ±50ppm/°C temperature coefficient, and -65°C to 175°C operating range. Physical dimensions and package type are identical. These parts are parametric equivalents suitable for interchangeable use.

Q: Are all three parts suitable for military applications?

A: Yes. All three parts are classified as military-grade resistors within the RN55 series and comply with MIL-R-10509/7 specifications. Each part features flame retardant coating, moisture resistance, and safety-rated construction appropriate for military-grade circuit applications.

Q: What determines whether a substitute part is acceptable for my circuit?

A: Substitution compatibility is determined by matching resistance value, power rating, tolerance, temperature coefficient, operating temperature range, and package type. The RN55E2003BB14 offers tighter tolerance and improved temperature stability. The RN55C2003FB14 provides identical specifications. Both are acceptable substitutes based on these parameters.

Q: Do these parts have different RoHS or REACH compliance status?

A: No. All three parts maintain identical RoHS non-compliant status and REACH affected classification. Compliance status does not differentiate these parts.
