Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNC50K2002FSBSL are qualified based on the following criteria:

Core Matching Parameters (Non-Negotiable):

• Resistance value: 20 kOhms
• Power rating: 0.1W (1/10W)
• Composition: Metal Film
• Package type: Axial
• Operating temperature range: -65°C to 175°C
• Series: Military, MIL-PRF-55182/07, RNC50
• Features: Military, Moisture Resistant, Weldable

Allowable Variations:

• Tolerance: May be tighter (±0.1%) or equal (±1%)
• Temperature coefficient: May be lower (±25ppm/°C or ±50ppm/°C) or equal (±100ppm/°C)
• Packaging format: Bulk or Cut Tape (CT)
• Failure rate: Consistent at S (0.001%)

The two identified substitutes meet all core matching parameters and represent upgrades or equivalent alternatives with improved or maintained electrical characteristics.

Engineering Selection Recommendations

All three parts—RNC50K2002FSBSL, RNC50H2002FSRE6, and RNC50J2002BSB14—are active military-grade components from the same manufacturer and series. Selection between them is determined by application requirements and packaging availability:

RNC50K2002FSBSL (Original): Suitable for applications requiring ±1% tolerance with standard temperature coefficient performance. Available in Bulk packaging.

RNC50H2002FSRE6: Provides improved temperature coefficient stability (±50ppm/°C versus ±100ppm/°C) while maintaining ±1% tolerance. Available in Cut Tape format, offering flexibility for automated assembly processes. REACH Affected status noted.

RNC50J2002BSB14: Offers the tightest tolerance specification (±0.1%) and lowest temperature coefficient (±25ppm/°C), suitable for precision circuit applications requiring enhanced stability. Available in Bulk packaging. REACH Affected status noted.

All parts maintain identical physical dimensions, operating temperature range, failure rate classification, and military-grade construction. RoHS non-compliance is consistent across all variants.

Frequently Asked Questions (FAQ)

Q: Can RNC50H2002FSRE6 be used as a direct replacement for RNC50K2002FSBSL?

A: Yes. Both parts share identical resistance, power rating, tolerance, operating temperature range, and physical dimensions. The RNC50H2002FSRE6 features a lower temperature coefficient (±50ppm/°C versus ±100ppm/°C), which represents improved performance. The primary difference is packaging format: Cut Tape versus Bulk.

Q: What is the advantage of RNC50J2002BSB14 over the original part?

A: RNC50J2002BSB14 provides tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±100ppm/°C). These characteristics reduce resistance drift across temperature variations and improve circuit accuracy. Selection depends on whether the application requires this enhanced precision.

Q: Are there packaging compatibility considerations?

A: Yes. RNC50K2002FSBSL and RNC50J2002BSB14 are supplied in Bulk packaging, while RNC50H2002FSRE6 is supplied in Cut Tape format. Cut Tape packaging is optimized for automated pick-and-place assembly, while Bulk packaging is suitable for manual assembly or reel-based processes.

Q: Do all substitute parts meet the same military specifications?

A: Yes. All three parts are qualified to Military MIL-PRF-55182/07 standard and carry the RNC50 series designation. All maintain identical failure rate classification (S, 0.001%), moisture resistance, and weldability features.

Q: What is the impact of RoHS non-compliance?

A: All parts carry RoHS non-compliant status. This designation applies uniformly across the RNC50 military series. Applications subject to RoHS requirements must account for this classification during design and procurement phases.

Q: How do temperature coefficient differences affect circuit performance?

A: Temperature coefficient defines resistance change per degree Celsius. RNC50J2002BSB14 (±25ppm/°C) exhibits minimal drift across the -65°C to 175°C operating range, followed by RNC50H2002FSRE6 (±50ppm/°C), then RNC50K2002FSBSL (±100ppm/°C). Applications with tight tolerance requirements or wide temperature operation benefit from lower temperature coefficients.
