RN65C2002FRSL Equivalent & Substitute Parts

Part Overview

The RN65C2002FRSL is a 20 kOhms ±1% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN65 series (MIL-R-10509/2), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part is currently active in production with 888 units in stock. Substitute parts may be required due to packaging format changes, tolerance upgrades, or inventory optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65C2002FRSL is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 20 kOhms (exact match required)
• Power rating: 0.5W (1/2W) (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.180" Dia × 0.562" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -65°C to 175°C (exact match or better required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Series compliance: MIL-R-10509/2, RN65 (exact match required)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±1%
• Packaging format: May differ (Tape & Reel to Bulk or vice versa)

The RN65C2002BB14 qualifies as a direct substitute because it maintains all mandatory electrical and mechanical parameters while offering an upgraded tolerance specification (±0.1% versus ±1%) and alternative packaging (Bulk versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The RN65C2002BB14 is a direct functional and mechanical substitute for the RN65C2002FRSL. Both components are active production parts manufactured by Vishay Dale under the same military-grade RN65 series specification (MIL-R-10509/2). The substitute part offers improved tolerance performance (±0.1% versus ±1%), which provides superior precision without compromising any electrical or thermal characteristics. Both parts maintain identical RoHS non-compliant and REACH Affected compliance status. The primary distinction is packaging format: the main part is supplied in Tape & Reel configuration while the substitute is supplied in Bulk format. This difference does not affect electrical performance or mechanical fit in circuit applications. Selection between these parts should be based on procurement requirements, inventory availability, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RN65C2002BB14 be used as a direct replacement for RN65C2002FRSL in existing designs?

A: Yes. Both components are electrically and mechanically identical in all critical parameters: 20 kOhms resistance, 0.5W power rating, ±50ppm/°C temperature coefficient, -65°C to 175°C operating range, and identical axial package dimensions (0.180" Dia × 0.562" L). The substitute offers tighter tolerance (±0.1% versus ±1%), which is a performance upgrade. Packaging format differs (Bulk versus Tape & Reel) but does not affect circuit functionality.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance specifies the allowable deviation from the nominal 20 kOhm resistance value. The RN65C2002FRSL allows ±1% deviation (19.8 kOhms to 20.2 kOhms), while RN65C2002BB14 allows ±0.1% deviation (19.98 kOhms to 20.02 kOhms). The substitute part provides tighter tolerance, resulting in more precise resistance values. This is beneficial for precision circuits but not required for general-purpose applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Both are manufactured to MIL-R-10509/2 military specification and feature identical flame retardant coating, moisture resistance, and safety construction.

Q: Does packaging format (Tape & Reel versus Bulk) affect component performance?

A: No. Packaging format affects only procurement, storage, and assembly handling. It does not alter electrical characteristics, thermal performance, or mechanical fit. Tape & Reel packaging is optimized for automated assembly, while Bulk packaging is suitable for manual assembly or alternative handling processes.

Q: Are both parts currently available?

A: Yes. RN65C2002FRSL has 888 units in stock, and RN65C2002BB14 has 707 units in stock, both listed as active production parts.
