Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1000FBSL is determined by strict equivalence in the following parameters: resistance value (100 Ohms), power rating (0.125W), package type (Axial), physical dimensions (0.090" Dia × 0.240" L), operating temperature range (-65°C to 175°C), and military series classification (MIL-R-10509/7, RN55). Tolerance and temperature coefficient variations are permitted within the RN55 series, as these parameters define performance grades rather than functional incompatibility. All identified substitutes maintain identical resistance, power rating, package configuration, and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are manufactured by Vishay Dale within the MIL-R-10509/7 military specification series. Selection between the main part and substitutes is based on tolerance and temperature coefficient requirements:

RN55C1000BB14 provides enhanced tolerance performance at ±0.1%, suitable for applications requiring tighter resistance accuracy than the standard ±1% specification.

RN55E1000FB14 offers improved temperature stability with a ±25ppm/°C coefficient compared to the ±50ppm/°C of the main part, applicable to temperature-sensitive circuit designs.

RN55C1000FB14 is a parametric equivalent with identical electrical specifications to the main part, differing only in packaging designation and offering the highest inventory availability at 2,022 units.

All parts comply with REACH regulations and carry identical RoHS non-compliant status, ECCN EAR99 classification, and HTSUS code 8533.21.0090.

Frequently Asked Questions (FAQ)

Q: Can RN55C1000BB14 be used as a direct replacement for RN55C1000FBSL?

A: Yes. RN55C1000BB14 is electrically and mechanically compatible. The ±0.1% tolerance is a performance upgrade that maintains backward compatibility with circuits designed for ±1% tolerance.

Q: What is the difference between RN55E1000FB14 and RN55C1000FBSL?

A: Both parts have identical resistance, power rating, and tolerance. RN55E1000FB14 features a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), resulting in better resistance stability across the -65°C to 175°C operating range.

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

A: Yes. All parts listed maintain identical physical dimensions of 0.090" Dia × 0.240" L (2.29mm × 6.10mm) and are configured as two-terminal axial components suitable for through-hole PCB assembly.

Q: Can these parts be used interchangeably in military applications?

A: Yes. All parts are manufactured to MIL-R-10509/7 specification and share identical military series classification, flame retardant coating, moisture resistance, and safety features required for military-grade electronic assemblies.

Q: What is the difference between an upgrade substitute and a parametric equivalent?

A: Upgrade substitutes (RN55C1000BB14 and RN55E1000FB14) offer enhanced performance characteristics—tighter tolerance or lower temperature coefficient—while maintaining full backward compatibility. Parametric equivalents (RN55C1000FB14) match all electrical specifications identically and differ only in packaging designation or manufacturing batch coding.
