Key Parameters

Substitute Part Grouping Explanation

The CMF5552K300FHEB qualifies as a substitute for the PRNF14FTD52K3 based on the following matching parameters:

• Identical resistance value: 52.3 kOhms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical package configuration: Axial
• Identical termination count: 2
• Matching compliance standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The substitute part differs in power rating (0.5W vs 0.25W), temperature coefficient (±50ppm/°C vs ±100ppm/°C), and maximum operating temperature (175°C vs 155°C). These differences represent enhanced specifications suitable for applications requiring higher thermal dissipation or improved stability.

Parameter Comparison

Engineering Selection Recommendations

Both the PRNF14FTD52K3 and CMF5552K300FHEB maintain active product status and full compliance with ROHS3 and REACH regulations. The CMF5552K300FHEB offers enhanced thermal performance with a higher power rating (0.5W vs 0.25W) and improved temperature stability (±50ppm/°C vs ±100ppm/°C), making it suitable for applications with elevated ambient temperatures or higher power dissipation requirements. The substitute part also incorporates moisture-resistant features in addition to flame retardant coating. Both components are available in axial configuration with identical electrical specifications for resistance and tolerance, ensuring direct functional compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the CMF5552K300FHEB directly replace the PRNF14FTD52K3 in existing designs?

A: Yes. Both components share identical resistance (52.3 kOhms), tolerance (±1%), composition (metal film), and axial package configuration. The substitute part provides enhanced specifications without compromising electrical compatibility.

Q: What are the physical dimension differences between these parts?

A: The PRNF14FTD52K3 measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). The CMF5552K300FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both dimensions are within typical axial resistor tolerances and suitable for standard PCB layouts.

Q: Why does the CMF5552K300FHEB have a higher power rating?

A: The 0.5W rating (versus 0.25W) reflects the substitute part's enhanced thermal dissipation capability. This does not affect applications designed for 0.25W operation; it provides additional margin for thermal stress.

Q: Are there packaging format differences?

A: The PRNF14FTD52K3 is supplied in Tape & Reel (TR) format. The CMF5552K300FHEB is supplied in Cut Tape (CT) format. Both are standard packaging methods for through-hole axial resistors.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under EAR99 with matching HTSUS codes (8533.21.0090).
