PRNF14FTD14K0 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD14K0 is a 14 kOhms ±1% 0.25W metal film through-hole resistor manufactured by Stackpole Electronics Inc in the RNF series. This 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 and ROHS3 compliant. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility are maintained across packaging formats or when upgraded performance specifications are required for specific application demands.

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD14K0 are classified based on the following criteria:

Direct Equivalent (Packaging Variant): RNF14FTD14K0 in Cut Tape (CT) packaging maintains identical electrical specifications—14 kOhms ±1% resistance, 0.25W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. This variant differs only in packaging format (Cut Tape versus Tape & Reel), making it suitable for applications where packaging logistics differ but component performance remains unchanged.

Upgraded Substitute (Enhanced Performance): CMF5514K000FHEB from Vishay Dale represents an upgraded option with the same 14 kOhms ±1% resistance value but increased power rating (0.5W versus 0.25W), improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C), and additional moisture-resistant features. This substitute is applicable when circuits require higher power dissipation capability or enhanced environmental performance.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD14K0 (Direct Equivalent): Select this variant when the application requires identical electrical performance to the PRNF14FTD14K0 but sourcing or inventory logistics necessitate Cut Tape packaging instead of Tape & Reel format. Both parts maintain ROHS3 compliance and equivalent thermal characteristics. This substitution is appropriate for direct component replacement without circuit redesign.

CMF5514K000FHEB (Upgraded Substitute): Select this Vishay Dale component when circuit design permits or requires enhanced performance specifications. The doubled power rating (0.5W) accommodates higher power dissipation without thermal stress. The improved temperature coefficient (±50ppm/°C) provides superior stability across temperature variations. The extended operating range (-55°C ~ 175°C) supports applications in elevated temperature environments. The moisture-resistant feature adds environmental protection. All parts maintain ROHS3 compliance and EAR99 export classification. This upgrade path is suitable when performance margins or environmental conditions exceed the original specification.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD14K0 (Cut Tape) directly replace PRNF14FTD14K0 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tape & Reel packaging is optimized for high-volume automated assembly, while Cut Tape is suitable for lower-volume or manual assembly processes. Component performance, tolerance, power rating, and temperature characteristics are equivalent.

Q: When should CMF5514K000FHEB be selected over the Stackpole RNF series?

A: The CMF5514K000FHEB upgrade is appropriate when: (1) circuit power dissipation exceeds 0.25W, requiring the 0.5W rating; (2) temperature stability is critical, benefiting from the ±50ppm/°C coefficient versus ±100ppm/°C; (3) operating environment reaches or exceeds 155°C, requiring the extended 175°C maximum; or (4) moisture exposure is a design consideration, utilizing the moisture-resistant feature.

Q: Are all substitute parts axial package configuration?

A: Yes. All listed parts—PRNF14FTD14K0, RNF14FTD14K0, and CMF5514K000FHEB—are axial through-hole resistors with identical lead configuration and PCB mounting compatibility.

Q: Do substitute parts maintain compliance certifications?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Compliance status is maintained across all substitutes.

Q: What is the physical size difference between PRNF14FTD14K0 and CMF5514K000FHEB?

A: PRNF14FTD14K0 dimensions are 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF5514K000FHEB dimensions are 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The CMF variant is marginally smaller, but both fit standard 0.1" pitch through-hole spacing on PCBs.
