PRNF14FTD2M00 Equivalent & Substitute Parts

Part Overview

The PRNF14FTD2M00 is a 2 MOhms ±1% 0.25W (1/4W) through-hole resistor with axial leads, manufactured by Stackpole Electronics Inc. This metal film resistor features flame retardant coating and safety construction, designed for general-purpose electronic applications requiring precision resistance values in compact form factors. The part is currently active in production with full RoHS3 compliance. Substitute parts may be required due to inventory availability, packaging format preferences, or performance requirement upgrades in specific application contexts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD2M00 is determined by the following critical parameters: resistance value (2 MOhms), tolerance (±1%), composition (metal film), and axial package configuration. All substitute parts must maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Equivalent: RNF14FTD2M00 (Stackpole Electronics Inc) maintains identical electrical specifications and differs only in packaging format (Cut Tape vs. Tape & Reel), making it a direct functional equivalent.

Upgrade Substitute: CMF552M0000FHEB (Vishay Dale) provides enhanced performance characteristics while maintaining core compatibility. This part increases power rating from 0.25W to 0.5W, improves temperature coefficient from ±100ppm/°C to ±50ppm/°C, and extends maximum operating temperature from 155°C to 175°C. The resistance value, tolerance, composition, and axial package remain identical.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD2M00 is selected when packaging format conversion from Tape & Reel to Cut Tape is required while maintaining identical electrical performance and specifications. Both parts share the same series designation (RNF) and are produced by the same manufacturer, ensuring consistent quality and reliability characteristics.

CMF552M0000FHEB is selected when applications require enhanced thermal stability or operation in elevated temperature environments. The improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C) provides superior frequency stability and reduced drift characteristics. The increased power rating (0.5W vs. 0.25W) accommodates higher dissipation requirements. All three parts maintain full regulatory compliance with RoHS3 and REACH requirements, suitable for commercial and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2M00 be used as a direct replacement for PRNF14FTD2M00?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: PRNF14FTD2M00 is supplied in Tape & Reel format, while RNF14FTD2M00 is supplied in Cut Tape format. Selection depends on assembly process requirements.

Q: What are the advantages of using CMF552M0000FHEB over PRNF14FTD2M00?

A: CMF552M0000FHEB provides three performance enhancements: doubled power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C for better stability), and extended maximum operating temperature (175°C vs. 155°C). These upgrades benefit applications with higher thermal demands or requiring superior frequency stability.

Q: Are all three parts physically compatible in the same PCB footprint?

A: Yes. All three parts use axial package configuration with identical lead spacing and mounting requirements. Physical board layout compatibility is maintained across all substitutes.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. PRNF14FTD2M00, RNF14FTD2M00, and CMF552M0000FHEB are all ROHS3 compliant and REACH unaffected, meeting current regulatory standards for commercial and industrial electronics.

Q: Which part should be selected for high-temperature applications?

A: CMF552M0000FHEB is specified for applications requiring operation up to 175°C. PRNF14FTD2M00 and RNF14FTD2M00 are rated to 155°C maximum.
