Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes (Identical Electrical Specifications):

• Resistance value: 332 Ohms
• Tolerance: ±1%
• Power rating: 0.25W minimum
• Composition: Metal Film
• Package: Axial configuration
• Operating temperature range: -55°C minimum to 155°C maximum
• RoHS3 compliance required

Upgrade Substitutes (Enhanced Power Rating):

• All electrical parameters identical to direct substitutes
• Power rating: 0.5W (1/2W) or higher
• Maintains or improves temperature coefficient performance
• Extends operating temperature range capability
• Backward compatible in circuits designed for 0.25W minimum

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD332R (Stackpole Electronics Inc): Direct electrical equivalent with identical 0.25W power rating and temperature specifications. Differs only in packaging format (Cut Tape vs. Tape & Reel). Selection is appropriate for applications requiring the same performance envelope with alternative procurement format.

RNMF12FTD332R (Stackpole Electronics Inc): Upgrade substitute with doubled power rating (0.5W vs. 0.25W) while maintaining all other electrical parameters. Temperature coefficient and operating range remain equivalent. Selection is appropriate for circuits where increased power dissipation capability is beneficial or required.

CMF55332R00FHEB (Vishay Dale): Upgrade substitute with 0.5W power rating and improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Extended operating temperature range to 175°C. All components maintain ROHS3 compliance and Active product status. Selection is appropriate for applications requiring superior temperature stability or extended thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD332R replace PRNF14FTD332R in all applications? A: Yes. Both components share identical electrical specifications (332 Ohms ±1%, 0.25W, metal film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range). The difference is packaging format only (Cut Tape vs. Tape & Reel).

Q: Are the 0.5W upgrade substitutes backward compatible? A: Yes. RNMF12FTD332R and CMF55332R00FHEB both maintain the same resistance value, tolerance, and temperature coefficient as the original 0.25W part. The higher power rating does not affect circuit operation in applications designed for 0.25W minimum.

Q: What is the physical size difference between parts? A: PRNF14FTD332R, RNF14FTD332R, and RNMF12FTD332R share identical dimensions (0.093" Dia x 0.250" L / 2.35mm x 6.35mm). CMF55332R00FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) but remains mechanically compatible in standard axial resistor footprints.

Q: Which substitute offers the best temperature stability? A: CMF55332R00FHEB provides the lowest temperature coefficient at ±50ppm/°C compared to ±100ppm/°C for all other listed parts. This component also extends the maximum operating temperature to 175°C.

Q: Are all substitutes ROHS3 compliant? A: Yes. PRNF14FTD332R, RNF14FTD332R, RNMF12FTD332R, and CMF55332R00FHEB are all ROHS3 compliant with Active product status.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is supplied on continuous tape wound on reels for automated assembly. Cut Tape (CT) packaging is supplied as individual tape segments. Both formats contain identical components; the difference is in procurement and handling format.
