PRNF14FTD2K80 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD2K80 is a 2.8 kOhms ±1% 0.25W through-hole resistor manufactured by Stackpole Electronics Inc in the RNF series. This metal film axial resistor features flame retardant coating and safety construction, designed for applications requiring precision resistance values with tight tolerance specifications. The part is currently active in production with ROHS3 compliance and REACH unaffected status, making it suitable for modern electronic assemblies.

Equivalent and substitute parts are identified when they maintain the same resistance value, tolerance, and core electrical characteristics while potentially offering variations in power rating, temperature coefficient, or packaging format that remain functionally compatible for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PRNF14FTD2K80 is determined by the following mandatory parameters:

• Resistance value: 2.8 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)

Variations permitted in substitute parts include power rating (when equal to or greater than 0.25W), temperature coefficient (when equal to or lower in absolute value), maximum operating temperature (when equal to or higher), and physical dimensions (within standard axial resistor tolerances). Packaging format may vary between Tape & Reel and Cut Tape configurations without affecting electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD2K80 serves as a direct equivalent to PRNF14FTD2K80, maintaining identical electrical specifications and physical dimensions. Both parts are manufactured by Stackpole Electronics Inc in the RNF series with active product status and full regulatory compliance (ROHS3, REACH unaffected).

CMF552K8000FHEB from Vishay Dale represents an upgrade substitute with enhanced performance characteristics. This part maintains the same resistance value and tolerance while offering increased power dissipation capability (0.5W versus 0.25W), improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), and extended maximum operating temperature (175°C versus 155°C). The CMF552K8000FHEB is supplied in Cut Tape format rather than Tape & Reel, with slightly reduced physical dimensions. All three parts maintain ROHS3 compliance and REACH unaffected status, confirming suitability for current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2K80 be used as a direct replacement for PRNF14FTD2K80?

A: Yes. RNF14FTD2K80 is a direct equivalent with identical resistance (2.8 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and physical dimensions. Both are manufactured by Stackpole Electronics Inc and maintain the same regulatory compliance status.

Q: What are the advantages of using CMF552K8000FHEB as a substitute?

A: CMF552K8000FHEB provides three performance enhancements: doubled power rating (0.5W versus 0.25W) for improved thermal margin, superior temperature coefficient (±50ppm/°C versus ±100ppm/°C) for better stability across temperature ranges, and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). Resistance value and tolerance remain identical at 2.8 kOhms ±1%.

Q: Are there packaging format differences between these parts?

A: Yes. PRNF14FTD2K80 and RNF14FTD2K80 are supplied in Tape & Reel format, while CMF552K8000FHEB is supplied in Cut Tape format. Both packaging formats are standard for through-hole resistor distribution and do not affect electrical performance or circuit compatibility.

Q: Do all three parts meet current regulatory requirements?

A: Yes. PRNF14FTD2K80, RNF14FTD2K80, and CMF552K8000FHEB are all ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and hazardous substance regulations.

Q: What are the physical dimension differences?

A: PRNF14FTD2K80 and RNF14FTD2K80 measure 0.093" diameter by 0.250" length (2.35mm x 6.35mm). CMF552K8000FHEB measures 0.090" diameter by 0.240" length (2.29mm x 6.10mm). These minor dimensional variations remain within standard axial resistor tolerances and do not affect PCB layout compatibility for typical through-hole applications.
