PRNF14FTD15K8 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD15K8 is a 15.8 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial configuration, manufactured by Stackpole Electronics Inc. This component is part of the RNF series and maintains active product status. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, composition) and mechanical compatibility (axial package, terminal configuration) while accommodating variations in packaging format and thermal performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD15K8 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Identical Electrical Specifications) Direct substitutes maintain all core electrical parameters: 15.8 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, and axial package configuration. These parts differ only in packaging format (Tape & Reel vs. Tape & Box vs. Cut Tape), which affects procurement and assembly logistics but not functional performance. All direct substitutes operate within the -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient.

Upgrade Substitute (Enhanced Thermal Performance) The CMF5515K800FHEB from Vishay Dale provides upgraded specifications while maintaining the same resistance value and tolerance. This part increases the power rating to 0.5W (1/2W), extends the operating temperature range to -55°C ~ 175°C, and reduces the temperature coefficient to ±50ppm/°C. The upgrade substitute is suitable for applications requiring enhanced thermal margin or operation at elevated temperatures.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

For Direct Substitution: RNF14FAD15K8 and RNF14FTD15K8 are functionally equivalent to PRNF14FTD15K8. Selection between these direct substitutes depends on packaging requirements: Tape & Reel for high-volume automated assembly, Tape & Box for mixed-volume procurement, or Cut Tape for low-volume or prototype applications.

For Upgraded Performance: CMF5515K800FHEB is suitable when applications require increased power dissipation capacity, extended temperature operation beyond 155°C, or improved temperature stability. The reduced temperature coefficient (±50ppm/°C vs. ±100ppm/°C) provides enhanced frequency stability in precision circuits. The addition of moisture-resistant features supports applications in humid or corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD15K8 and RNF14FTD15K8 be used interchangeably with PRNF14FTD15K8? A: Yes. These parts share identical electrical specifications (15.8 kOhms, ±1%, 0.25W) and mechanical configuration (axial, metal film). Differences in packaging format (Tape & Reel, Tape & Box, Cut Tape) do not affect circuit performance.

Q: What is the primary difference between the Stackpole RNF series and the Vishay Dale CMF5515K800FHEB? A: The CMF5515K800FHEB provides enhanced thermal performance with 0.5W power rating (vs. 0.25W), extended temperature range to 175°C (vs. 155°C), and improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Resistance value and tolerance remain identical.

Q: When should CMF5515K800FHEB be selected over direct substitutes? A: Select the CMF5515K800FHEB when circuit design requires higher power dissipation margin, operation at temperatures exceeding 155°C, or applications demanding superior frequency stability and moisture resistance.

Q: Are all substitute parts suitable for the same PCB footprint? A: All parts use axial package configuration with 2 terminations. Physical dimensions are comparable (0.093" Dia x 0.250" L for Stackpole; 0.090" Dia x 0.240" L for Vishay Dale), supporting standard axial component footprints. Verify PCB layout constraints for dimensional variations.

Q: Do packaging format differences affect electrical performance? A: No. Tape & Reel, Tape & Box, and Cut Tape formats are procurement and assembly variations only. Electrical and thermal characteristics remain unchanged.
