Key Parameters

Substitute Part Grouping Explanation

Substitution within the RNC55K2003FSRSL family is determined by the following criteria:

Electrical Parameters (Non-Negotiable):

• Resistance value: 200 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Failure rate classification: S (0.001%)

Mechanical Parameters (Non-Negotiable):

• Package type: Axial
• Physical dimensions: 0.094" Dia x 0.250" L (2.39mm x 6.35mm)
• Number of terminations: 2

Variable Parameters (Allowed for Substitution):

• Temperature coefficient: ±100ppm/°C (main part) to ±50ppm/°C (substitute parts)
• Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT)

The identified substitute parts RNC55H2003FSB14 and RNC55H2003FSRE6 maintain all electrical and mechanical specifications while offering improved temperature coefficient performance (±50ppm/°C) and alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with military specifications MIL-PRF-55182/01. Selection between RNC55K2003FSRSL, RNC55H2003FSB14, and RNC55H2003FSRE6 is determined by packaging requirements and temperature stability needs:

RNC55K2003FSRSL (Tape & Reel): Primary selection for automated assembly processes requiring tape-and-reel packaging format. Temperature coefficient of ±100ppm/°C is suitable for standard military applications.

RNC55H2003FSB14 (Bulk): Selection for manual assembly or low-volume production runs. Offers improved temperature coefficient of ±50ppm/°C for applications requiring enhanced thermal stability. Bulk packaging reduces per-unit cost for large quantities.

RNC55H2003FSRE6 (Cut Tape): Selection for mixed-volume applications or component kitting. Provides improved temperature coefficient of ±50ppm/°C with flexible packaging format. Highest inventory availability (2470 pcs) supports rapid procurement.

All parts are RoHS non-compliant and carry identical electrical performance within the specified tolerance and operating range.

Frequently Asked Questions (FAQ)

Q: Can RNC55H2003FSB14 or RNC55H2003FSRE6 be used as direct replacements for RNC55K2003FSRSL?

A: Yes. Both substitute parts maintain identical resistance value (200 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), operating temperature range (-65°C to 175°C), physical dimensions (0.094" Dia x 0.250" L), and failure rate classification (S, 0.001%). The primary differences are packaging format and temperature coefficient. Electrical performance is equivalent within specified parameters.

Q: What is the significance of the temperature coefficient difference between ±100ppm/°C and ±50ppm/°C?

A: Temperature coefficient defines the rate of resistance change per degree Celsius. The RNC55K2003FSRSL exhibits ±100ppm/°C, while RNC55H2003FSB14 and RNC55H2003FSRE6 exhibit ±50ppm/°C. The lower coefficient in substitute parts indicates superior thermal stability. For a 200 kOhms resistor operating across the full -65°C to 175°C range (240°C span), the RNC55K2003FSRSL may experience up to ±2.4 kOhms drift, while substitute parts may experience up to ±1.2 kOhms drift. Selection depends on circuit tolerance requirements.

Q: How do packaging formats affect component selection?

A: Tape & Reel (TR) packaging is optimized for high-speed automated assembly equipment. Bulk packaging is suitable for manual assembly or low-volume production. Cut Tape (CT) packaging provides flexibility for mixed-volume applications and component kitting. All three formats contain identical components; selection is based on assembly process requirements and inventory management strategy.

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

A: Yes. RNC55K2003FSRSL, RNC55H2003FSB14, and RNC55H2003FSRE6 are all classified as military-grade components within the RNC55 series and comply with MIL-PRF-55182/01 specifications. All maintain active product status and identical failure rate classification.

Q: What is the difference between RoHS compliance status across these parts?

A: All three parts are RoHS non-compliant. RNC55H2003FSB14 and RNC55H2003FSRE6 carry REACH Affected status, indicating they are subject to REACH regulatory requirements. This distinction does not affect electrical or mechanical compatibility but may impact procurement and documentation requirements for specific applications or regions.
