RN50C2001FBSL Equivalent & Substitute Parts

Part Overview

The RN50C2001FBSL is a 2 kOhms ±1% metal film through-hole resistor rated at 0.05W (1/20W) in axial package configuration. This component is part of Vishay Dale's military-grade RN50 series, designed to MIL-R-10509/8 specifications with flame retardant coating and moisture resistance. The part maintains active product status with 845 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, inventory availability, or procurement optimization while maintaining identical functional performance in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN50C2001FBSL is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (2 kOhms), tolerance (±1%), and power rating (0.05W) must be identical
• Thermal Characteristics: Temperature coefficient (±50ppm/°C) and operating temperature range (-65°C to 175°C) must match
• Physical Form Factor: Axial package configuration and dimensions (0.065" Dia x 0.150" L) must be maintained
• Material Composition: Metal film construction with flame retardant coating is required
• Military Compliance: MIL-R-10509/8 series classification and military-grade specifications must be preserved

The RN50C2001FB14 meets all substitution criteria as a parametric equivalent within the RN50 military resistor series.

Parameter Comparison

Engineering Selection Recommendations

Both RN50C2001FBSL and RN50C2001FB14 are active products manufactured by Vishay Dale with identical electrical, thermal, and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: RN50C2001FB14 maintains higher stock levels (915 units versus 845 units)
• Supply Chain Continuity: Both parts share identical MIL-R-10509/8 military specifications and RN50 series classification, ensuring interchangeability without circuit redesign
• Compliance Status: Both parts carry identical RoHS non-compliant and REACH Affected designations with EAR99 ECCN classification

No performance differentiation exists between these parts. Selection may be driven by procurement lead times, supplier availability, or inventory management objectives.

Frequently Asked Questions (FAQ)

Q: Can RN50C2001FB14 be used as a direct replacement for RN50C2001FBSL in existing designs?

A: Yes. Both parts are parametric equivalents with identical resistance (2 kOhms), tolerance (±1%), power rating (0.05W), temperature coefficient (±50ppm/°C), operating range (-65°C to 175°C), and axial package dimensions. No circuit modifications are required.

Q: Are there any differences in military specification compliance between these parts?

A: No. Both parts conform to MIL-R-10509/8 specifications and are classified within the RN50 military resistor series. Military-grade features including flame retardant coating and moisture resistance are identical.

Q: What determines substitution eligibility for the RN50C2001FBSL?

A: Substitution requires exact matching of resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, physical dimensions, and material composition. The RN50C2001FB14 meets all these criteria.

Q: Are there any packaging or form factor differences?

A: No. Both parts use identical axial package configuration with dimensions of 0.065" Dia x 0.150" L (1.65mm x 3.81mm). PCB layout and mechanical mounting are interchangeable.

Q: What is the basis for these substitute relationships?

A: Substitution is based strictly on parametric equivalence across electrical specifications (resistance, tolerance, power), thermal characteristics (temperature coefficient, operating range), physical form factor (axial package, dimensions), material composition (metal film), and military compliance standards (MIL-R-10509/8).
