RNF14FAD86K6 Equivalent & Substitute Parts

Part Overview

The RNF14FAD86K6 is an 86.6 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration, manufactured by Stackpole Electronics Inc. This component features flame retardant coating and safety-rated construction, designed for applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status. Equivalent and substitute parts may be required due to packaging format availability, inventory constraints, or application-specific performance requirements such as increased power dissipation capability or enhanced temperature stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD86K6 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 86.6 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Packaging format (Tape & Box to Tape & Reel or Cut Tape)
• Power rating (equal or greater than 0.25W)
• Temperature coefficient (equal or better stability)
• Maximum operating temperature (equal or higher)
• Manufacturer (different suppliers with equivalent specifications)

The RNF14FTD86K6 qualifies as a direct equivalent, differing only in packaging format (Tape & Reel versus Tape & Box). The CMF5586K600FHEB qualifies as an upgrade substitute, offering increased power dissipation (0.5W versus 0.25W), improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), and extended maximum operating temperature (175°C versus 155°C), while maintaining all other critical specifications.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD86K6 (Direct Equivalent): Select this part when the application requires identical electrical and thermal specifications to the RNF14FAD86K6 but packaging format must be Tape & Reel for automated assembly processes. Both parts are manufactured by Stackpole Electronics Inc, maintain active production status, and carry ROHS3 compliance certification. No performance trade-offs exist between these two options.

CMF5586K600FHEB (Upgrade Substitute): Select this part when the application can benefit from increased power dissipation capability (0.5W versus 0.25W), improved temperature stability (±50ppm/°C versus ±100ppm/°C), or extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). This Vishay Dale component maintains ROHS3 compliance and active production status. The upgrade is suitable for applications with higher thermal stress or requiring superior long-term stability. Physical dimensions are comparable (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), ensuring compatibility with standard axial component footprints.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD86K6 be used as a direct replacement for RNF14FAD86K6?

A: Yes. Both parts are electrically and thermally identical, with the only difference being packaging format (Tape & Reel versus Tape & Box). They share the same resistance value, tolerance, power rating, temperature coefficient, and operating range. Selection depends on assembly process requirements.

Q: What are the advantages of using CMF5586K600FHEB instead of RNF14FAD86K6?

A: The CMF5586K600FHEB offers three performance improvements: doubled power dissipation capability (0.5W versus 0.25W), superior temperature stability (±50ppm/°C versus ±100ppm/°C), and extended maximum operating temperature (175°C versus 155°C). These upgrades benefit applications subject to higher thermal stress or requiring enhanced long-term accuracy.

Q: Are all three parts RoHS compliant?

A: Yes. RNF14FAD86K6, RNF14FTD86K6, and CMF5586K600FHEB are all ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: Will CMF5586K600FHEB fit the same PCB footprint as RNF14FAD86K6?

A: Yes. Both components are axial package resistors with comparable physical dimensions. CMF5586K600FHEB measures 0.090" Dia x 0.240" L, while RNF14FAD86K6 measures 0.093" Dia x 0.250" L. These minor dimensional differences do not affect standard axial component footprint compatibility.

Q: Can I use a lower power rating substitute if my application only requires 0.25W?

A: No. Substitutes must meet or exceed the original power rating specification. Using a lower-rated component creates reliability risk and violates engineering design principles.

Q: What is the difference between Tape & Box, Tape & Reel, and Cut Tape packaging?

A: These are supply format variations for the same component. Tape & Box (TB) provides small quantities in boxed tape format. Tape & Reel (TR) supplies components on continuous reels for high-volume automated assembly. Cut Tape (CT) provides tape segments for medium-volume applications. Electrical performance is identical across all packaging formats.
