Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNC50K2001FSRSL are qualified based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 2 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Failure rate classification: S (0.001%)

Mechanical Parameters (Must Match Exactly):

• Package type: Axial
• Physical dimensions: 0.070" Dia x 0.150" L (1.78mm x 3.81mm)
• Number of terminations: 2

Allowed Variation Parameters:

• Temperature coefficient: ±100ppm/°C to ±50ppm/°C (lower values represent improved stability)
• Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT)

The two identified substitutes, RNC50H2001FSB14 and RNC50H2001FSRE6, maintain all critical electrical and mechanical specifications while offering improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C) and alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—RNC50K2001FSRSL, RNC50H2001FSB14, and RNC50H2001FSRE6—are active military-grade components manufactured by Vishay Dale under the MIL-PRF-55182/07 specification. Selection between these parts is determined by packaging requirements and application constraints:

RNC50K2001FSRSL (Tape & Reel): Primary selection for automated assembly processes requiring continuous tape-fed component delivery. Suitable for high-volume production environments with pick-and-place equipment.

RNC50H2001FSB14 (Bulk): Selection for manual assembly, kit preparation, or applications where individual component handling is required. Bulk packaging reduces per-unit cost for low-to-medium volume applications.

RNC50H2001FSRE6 (Cut Tape): Selection for mixed-volume production or prototype development requiring smaller quantities than full tape reels. Cut tape format provides flexibility between bulk and reel packaging options.

The temperature coefficient improvement in RNC50H2001FSB14 and RNC50H2001FSRE6 (±50ppm/°C versus ±100ppm/°C) provides enhanced frequency stability and reduced drift characteristics across the operating temperature range, beneficial for precision analog circuits and frequency-dependent applications.

Frequently Asked Questions (FAQ)

Q: Can RNC50H2001FSB14 or RNC50H2001FSRE6 be used as direct replacements for RNC50K2001FSRSL?

A: Yes. Both substitute parts maintain identical electrical specifications (2 kOhms ±1%, 0.1W, metal film composition) and mechanical dimensions (0.070" Dia x 0.150" L axial package). The primary differences are packaging format and temperature coefficient. Substitution is electrically and mechanically valid for any application using the original part.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient defines resistance value drift per degree Celsius change. RNC50H2001FSB14 and RNC50H2001FSRE6 specify ±50ppm/°C compared to ±100ppm/°C for RNC50K2001FSRSL. Lower temperature coefficient values indicate superior stability across temperature extremes, reducing resistance variation in circuits sensitive to component drift.

Q: How do packaging formats affect component selection?

A: Tape & Reel (TR) packaging is optimized for automated assembly with continuous tape feed. Bulk packaging suits manual assembly and kit applications. Cut Tape (CT) provides intermediate flexibility for smaller production runs. All three formats contain identical components; selection depends on assembly process and volume requirements.

Q: Are all three parts compliant with military specifications?

A: All three parts are classified as military-grade components per MIL-PRF-55182/07 and carry identical failure rate ratings (S, 0.001%). All maintain active production status with current inventory availability.

Q: Can these parts be intermixed in the same assembly?

A: Yes. Identical electrical and mechanical specifications permit intermixing across packaging formats within a single assembly or production batch without performance impact.
