PRNF14FTD232R Equivalent & Substitute Parts

Part Overview

The PRNF14FTD232R is a 232 Ohm ±1% metal film through-hole resistor rated at 0.25W (1/4W) with axial leads, manufactured by Stackpole Electronics Inc. This component is classified as Active and is ROHS3 compliant. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging requirements or enhanced performance specifications when needed for production or redesign scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PRNF14FTD232R is determined by the following critical parameters:

• Resistance value: 232 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial configuration (exact match required)
• Power rating: Minimum 0.25W (equal or higher acceptable)
• Temperature coefficient: ±100ppm/°C or better (lower values acceptable)
• Operating temperature range: Minimum -55°C to 155°C (wider ranges acceptable)
• RoHS compliance: ROHS3 Compliant (required)

Two substitute parts meet these criteria: RNF14FTD232R (direct equivalent with different packaging) and CMF55232R00FHEB (upgraded specification with higher power rating and improved temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD232R serves as a direct equivalent to PRNF14FTD232R with identical electrical specifications and physical dimensions. The primary distinction is packaging format: PRNF14FTD232R is supplied in Tape & Reel (TR) configuration, while RNF14FTD232R is supplied in Cut Tape (CT) configuration. Both are Active status products from Stackpole Electronics Inc and maintain full ROHS3 and REACH compliance.

CMF55232R00FHEB represents an upgraded specification option manufactured by Vishay Dale. This part maintains the same 232 Ohm resistance and ±1% tolerance but offers enhanced performance characteristics: doubled power rating (0.5W versus 0.25W), improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). Physical dimensions are slightly smaller. This part is suitable for applications requiring higher power dissipation capability or superior temperature stability. All compliance certifications remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD232R be used as a direct replacement for PRNF14FTD232R?

A: Yes. RNF14FTD232R is electrically and mechanically identical to PRNF14FTD232R. The only difference is packaging format (Cut Tape versus Tape & Reel). Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

Q: What are the advantages of using CMF55232R00FHEB over PRNF14FTD232R?

A: CMF55232R00FHEB provides three performance enhancements: (1) doubled power rating allows higher current handling without exceeding thermal limits, (2) improved temperature coefficient (±50ppm/°C) provides better resistance stability across temperature variations, and (3) extended operating temperature range supports applications requiring operation up to 175°C.

Q: Are there any physical compatibility concerns when substituting CMF55232R00FHEB?

A: CMF55232R00FHEB has slightly smaller physical dimensions (0.090" Dia x 0.240" L) compared to PRNF14FTD232R (0.093" Dia x 0.250" L). Both are axial configuration with two terminations. PCB layout and mechanical clearance should be verified, though the dimensional difference is minimal for most applications.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. PRNF14FTD232R, RNF14FTD232R, and CMF55232R00FHEB are all ROHS3 compliant and REACH unaffected. ECCN and HTSUS classifications are identical across all three parts.

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

A: CMF55232R00FHEB supports operation up to 175°C, compared to 155°C maximum for PRNF14FTD232R and RNF14FTD232R. For applications requiring sustained operation above 155°C, CMF55232R00FHEB is the appropriate selection.
