Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNC50K2002FSRSL are qualified based on the following electrical and mechanical parameters:

Core Substitution Criteria:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.1W minimum
• Package type: Axial (through-hole)
• Operating temperature range: -65°C to 175°C minimum
• Composition: Metal film
• Series compliance: Military MIL-PRF-55182/07 RNC50 base product

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1% (±0.1% acceptable)
• Temperature coefficient: May be equal to or lower than ±100ppm/°C
• Packaging format: Tape & Reel (TR), Cut Tape (CT), or Bulk formats are interchangeable for the same electrical component

Two substitute parts meet these criteria: RNC50H2002FSRE6 and RNC50J2002BSB14, both maintaining the RNC50 base product designation and military series classification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and share identical electrical specifications for resistance, power rating, and operating temperature range. Selection between RNC50K2002FSRSL and its substitutes is determined by tolerance and temperature coefficient requirements, with both substitute parts offering improved performance characteristics.

RNC50H2002FSRE6 provides a tighter temperature coefficient (±50ppm/°C versus ±100ppm/°C) while maintaining ±1% tolerance, suitable for applications requiring enhanced thermal stability. RNC50J2002BSB14 offers the tightest tolerance specification (±0.1%) and lowest temperature coefficient (±25ppm/°C), appropriate for precision circuit applications where component accuracy is critical.

Packaging format selection (Tape & Reel, Cut Tape, or Bulk) depends on assembly process requirements and procurement volume. All parts comply with identical military specifications and failure rate classifications.

Frequently Asked Questions (FAQ)

Q: Can RNC50H2002FSRE6 directly replace RNC50K2002FSRSL?

A: Yes. Both parts share identical resistance (20 kOhms), tolerance (±1%), power rating (0.1W), operating temperature range (-65°C to 175°C), and axial package configuration. RNC50H2002FSRE6 features a lower temperature coefficient (±50ppm/°C), which is a performance improvement for thermal stability.

Q: What is the difference between RNC50J2002BSB14 and the main part?

A: RNC50J2002BSB14 maintains all core electrical parameters but offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±100ppm/°C). These are performance enhancements suitable for precision applications.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR), Cut Tape (CT), and Bulk packaging formats contain identical electrical components. Packaging selection is determined by assembly equipment compatibility and procurement requirements.

Q: Are all substitute parts military-qualified?

A: Yes. All three parts comply with Military MIL-PRF-55182/07 specifications and carry the RNC50 base product designation. All maintain S-class failure rate (0.001%) and military-grade moisture resistance with weldable construction.

Q: Can RNC50J2002BSB14 be used in applications designed for RNC50K2002FSRSL?

A: Yes. RNC50J2002BSB14 meets or exceeds all electrical requirements of RNC50K2002FSRSL. The tighter tolerance and lower temperature coefficient represent performance improvements compatible with any application specified for the original part.
