PRNF14FTD24K3 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD24K3 is a 24.3 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 PRNF14FTD24K3 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Same Electrical Specifications):

• RNF14FAD24K3 (Stackpole Electronics Inc)
• RNF14FTD24K3 (Stackpole Electronics Inc)

These parts maintain identical resistance value (24.3 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Differences are limited to packaging format (Tape & Box vs. Tape & Reel vs. Cut Tape), which does not affect electrical performance or mechanical fit in standard through-hole applications.

Upgrade Substitute (Higher Power Rating):

• CMF5524K300FHEB (Vishay Dale)

This part maintains the same resistance value (24.3 kOhms) and tolerance (±1%) but provides enhanced thermal performance with a 0.5W (1/2W) power rating, improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C). The axial package and mechanical dimensions remain compatible with standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Same Electrical Performance): RNF14FAD24K3 and RNF14FTD24K3 are electrically and mechanically equivalent to PRNF14FTD24K3. Selection between these three parts is determined by packaging requirements: Tape & Reel for high-volume automated assembly, Tape & Box for mixed-volume applications, and Cut Tape for lower-volume or manual assembly processes. All three maintain ROHS3 compliance and active product status.

For Upgraded Performance: CMF5524K300FHEB from Vishay Dale provides enhanced thermal margin with doubled power rating (0.5W vs. 0.25W), superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). This upgrade is suitable for applications requiring improved thermal stability or operation at elevated temperatures. The part maintains ROHS3 compliance and active product status. Mechanical compatibility with standard through-hole PCB layouts is preserved.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD24K3 or RNF14FTD24K3 be used interchangeably with PRNF14FTD24K3?

A: Yes. All three parts share identical electrical specifications (24.3 kOhms ±1%, 0.25W, metal film composition, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and axial package configuration. Differences are limited to packaging format (Tape & Reel, Tape & Box, or Cut Tape), which affects procurement and assembly logistics but not electrical performance or PCB fit.

Q: When should CMF5524K300FHEB be selected instead of the standard 0.25W options?

A: CMF5524K300FHEB is selected when the application requires higher power dissipation capability (0.5W vs. 0.25W), improved temperature stability (±50ppm/°C vs. ±100ppm/°C), or operation at temperatures exceeding 155°C (up to 175°C maximum). The upgrade maintains the same 24.3 kOhms resistance value and ±1% tolerance, ensuring electrical compatibility while providing enhanced thermal performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PRNF14FTD24K3, RNF14FAD24K3, RNF14FTD24K3, and CMF5524K300FHEB are all ROHS3 compliant. REACH status is unaffected for all parts.

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

A: Tape & Reel (TR) is optimized for high-volume automated pick-and-place assembly. Tape & Box (TB) combines tape packaging with box containment for mixed-volume applications. Cut Tape (CT) provides individual component strips for lower-volume or manual assembly. All three formats contain the same component; packaging selection is based on assembly process requirements.

Q: Are the physical dimensions compatible across all substitute parts?

A: PRNF14FTD24K3, RNF14FAD24K3, and RNF14FTD24K3 share identical dimensions (0.093" Dia x 0.250" L / 2.35mm x 6.35mm). CMF5524K300FHEB has slightly different dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) but maintains axial configuration and standard through-hole compatibility. Both dimension sets are compatible with conventional PCB layouts designed for 1/4W and 1/2W axial resistors.
