Key Parameters

Substitute Part Grouping Explanation

Substitution for the RNC55K2002FSRSL is determined by the following critical parameters that must remain constant or improve:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Metal film (required for performance consistency)
• Operating temperature range: -65°C to 175°C minimum (equal or wider acceptable)
• Military specification compliance: MIL-PRF-55182/01 (required)
• Package type: Axial (required for mechanical compatibility)

Substitute parts are grouped based on tolerance specification and packaging format. The RNC55K2002FSRSL operates at ±1% tolerance. Substitute RNC55H2002BSB14 offers improved tolerance at ±0.1%, making it a direct functional upgrade. Substitute RNC55H2002FSRE6 maintains ±1% tolerance with alternative packaging. Both substitutes maintain identical resistance, power rating, operating temperature range, and military specification compliance.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with MIL-PRF-55182/01 military specification. Selection between the main part and substitutes depends on specific application requirements:

RNC55K2002FSRSL is the primary specification with ±1% tolerance and Tape & Reel packaging, suitable for automated assembly processes requiring standard tolerance performance.

RNC55H2002BSB14 provides improved tolerance at ±0.1% with reduced temperature coefficient (±50ppm/°C versus ±100ppm/°C), available in bulk packaging. This substitute is appropriate for applications requiring tighter tolerance control and enhanced temperature stability.

RNC55H2002FSRE6 maintains ±1% tolerance matching the main part with improved temperature coefficient (±50ppm/°C), available in Cut Tape format. This substitute accommodates alternative packaging requirements while providing enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can RNC55H2002BSB14 replace RNC55K2002FSRSL in all applications?

A: RNC55H2002BSB14 is functionally compatible as a direct substitute. It maintains identical resistance, power rating, and operating temperature range. The improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C) represent performance enhancements. Packaging differs (Bulk versus Tape & Reel), which may affect procurement and assembly processes.

Q: What is the difference between Tape & Reel, Cut Tape, and Bulk packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly with continuous tape spools. Cut Tape (CT) provides individual tape segments for semi-automated or manual assembly. Bulk packaging supplies loose components without tape format, typically for manual assembly or kit applications. All three formats contain identical components; packaging selection depends on assembly methodology and procurement volume.

Q: Are all three parts compliant with MIL-PRF-55182/01?

A: Yes. RNC55K2002FSRSL, RNC55H2002BSB14, and RNC55H2002FSRE6 are all part of the military-grade RNC55 series and comply with MIL-PRF-55182/01 specification. All maintain identical failure rate classification (S, 0.001%) and military-grade construction with moisture-resistant, weldable characteristics.

Q: Which substitute offers the best temperature stability?

A: Both RNC55H2002BSB14 and RNC55H2002FSRE6 provide superior temperature stability with ±50ppm/°C temperature coefficient compared to the main part's ±100ppm/°C. Selection between these two depends on tolerance requirements (±0.1% for BSB14 versus ±1% for FSRE6) and packaging format preference.

Q: Can these parts be used interchangeably in existing designs?

A: All three parts share identical resistance value (20 kOhms), power rating (0.125W), axial package type, and operating temperature range (-65°C to 175°C). Mechanical compatibility is confirmed. Electrical performance differences relate to tolerance and temperature coefficient specifications. Design verification should confirm that improved tolerance and temperature coefficient characteristics do not introduce unintended circuit behavior.
