Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRNF14FTD23K7 are classified based on the following criteria:

Direct Equivalent (Same Packaging): RNF14FTD23K7 maintains identical electrical specifications and axial package configuration. The only difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect component functionality or board-level compatibility.

Upgrade Substitute (Enhanced Specifications): CMF5523K700FHEB is classified as an upgrade substitute because it maintains the core electrical parameters (23.7 kOhms ±1% resistance, metal film composition, axial package) while providing enhanced performance characteristics: increased power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), and additional moisture-resistant features.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD23K7 is the direct equivalent substitute for PRNF14FTD23K7. Both components are manufactured by Stackpole Electronics Inc, maintain identical electrical and mechanical specifications, and are Active products with ROHS3 compliance. Selection between these parts is determined by packaging requirements: Tape & Reel (TR) for PRNF14FTD23K7 or Cut Tape (CT) for RNF14FTD23K7.

CMF5523K700FHEB is an upgrade substitute suitable for applications requiring enhanced thermal performance or extended operating temperature ranges. This Vishay Dale component provides increased power dissipation capability (0.5W vs. 0.25W), superior temperature stability (±50ppm/°C vs. ±100ppm/°C), and moisture-resistant features. Selection of this upgrade is appropriate when circuit design margins or environmental conditions exceed the specifications of the primary part.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD23K7 be used as a direct replacement for PRNF14FTD23K7?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: PRNF14FTD23K7 is supplied in Tape & Reel format, while RNF14FTD23K7 is supplied in Cut Tape format. Board-level performance and compatibility are unaffected by this packaging difference.

Q: When should CMF5523K700FHEB be selected over the primary part?

A: CMF5523K700FHEB should be selected when circuit requirements include higher power dissipation (0.5W vs. 0.25W), extended operating temperatures above 155°C, or applications requiring improved temperature stability (±50ppm/°C vs. ±100ppm/°C). The moisture-resistant feature provides additional protection in humid environments.

Q: Are all substitute parts axial configuration?

A: Yes. All listed parts—PRNF14FTD23K7, RNF14FTD23K7, and CMF5523K700FHEB—are supplied in axial package configuration and are mechanically compatible with standard through-hole PCB layouts.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. PRNF14FTD23K7, RNF14FTD23K7, and CMF5523K700FHEB are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the physical size difference between PRNF14FTD23K7 and CMF5523K700FHEB?

A: PRNF14FTD23K7 dimensions are 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CMF5523K700FHEB dimensions are 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Both fit standard axial resistor footprints with minimal dimensional variation.
