PRNF14FTD4K53 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD4K53 is a 4.53 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) and mechanical compatibility (axial package, lead configuration) while accounting for packaging format variations and performance enhancements available from qualified manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD4K53 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Equivalent Performance):

• RNF14FAD4K53 (Stackpole Electronics Inc)
• RNF14FTD4K53 (Stackpole Electronics Inc)

These parts maintain identical electrical specifications: 4.53 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, and -55°C ~ 155°C operating range. Differences are limited to packaging format (Tape & Box vs. Tape & Reel vs. Cut Tape), which does not affect circuit performance or mechanical fit in standard through-hole applications.

Upgrade Substitute (Enhanced Performance):

• CMF554K5300FHEB (Vishay Dale)

This part provides the same 4.53 kOhms ±1% resistance and axial package configuration but with enhanced specifications: 0.5W (1/2W) power rating, ±50ppm/°C temperature coefficient (improved stability), and extended operating temperature to 175°C. The upgrade is suitable for applications requiring higher power dissipation capability or tighter temperature stability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select RNF14FAD4K53 or RNF14FTD4K53 when the original PRNF14FTD4K53 is unavailable. Both maintain identical electrical performance and are ROHS3 compliant. Choice between these direct substitutes depends on packaging requirements: RNF14FAD4K53 is supplied in Tape & Box format, while RNF14FTD4K53 is supplied in Cut Tape format. Both are suitable for standard through-hole PCB assembly processes.

For Performance Enhancement: Select CMF554K5300FHEB when the application requires higher power dissipation (0.5W vs. 0.25W) or improved temperature stability (±50ppm/°C vs. ±100ppm/°C). This upgrade maintains the same 4.53 kOhms resistance and ±1% tolerance, ensuring circuit compatibility while providing extended operating temperature range to 175°C. ROHS3 compliance is maintained across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can RNF14FAD4K53 be used as a direct replacement for PRNF14FTD4K53? A: Yes. Both parts have identical electrical specifications (4.53 kOhms ±1%, 0.25W, metal film, axial package). The difference is packaging format: RNF14FAD4K53 uses Tape & Box while PRNF14FTD4K53 uses Tape & Reel. Circuit performance and mechanical fit are equivalent.

Q: What is the difference between the direct substitutes and CMF554K5300FHEB? A: Direct substitutes (RNF14FAD4K53, RNF14FTD4K53) match the original 0.25W power rating and ±100ppm/°C temperature coefficient. CMF554K5300FHEB provides enhanced specifications: 0.5W power rating and ±50ppm/°C temperature coefficient, with extended operating temperature to 175°C. Resistance and tolerance remain identical at 4.53 kOhms ±1%.

Q: Are all substitute parts ROHS3 compliant? A: Yes. PRNF14FTD4K53, RNF14FAD4K53, RNF14FTD4K53, and CMF554K5300FHEB are all ROHS3 compliant with REACH Unaffected status.

Q: Does packaging format affect circuit performance? A: No. Tape & Reel (TR), Tape & Box (TB), and Cut Tape (CT) packaging formats are logistics variations only. They do not affect electrical performance or mechanical compatibility in through-hole PCB applications.

Q: When should CMF554K5300FHEB be selected over direct substitutes? A: Select CMF554K5300FHEB when the circuit requires higher power dissipation capability, improved temperature stability, or operation at temperatures above 155°C. The 0.5W rating and ±50ppm/°C coefficient provide performance margin in demanding thermal or high-power applications.
