Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRNF14FTD4K64 is determined by the following critical parameters:

Direct Equivalence Criteria:

• Resistance value: 4.64 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package: Axial configuration
• Terminations: 2-pin

Upgrade Criteria: The CMF554K6400FHEB qualifies as an upgrade substitute when higher power dissipation capacity or extended temperature performance is required, provided the axial package footprint remains compatible with circuit board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

PRNF14FTD4K64 / RNF14FTD4K64 Selection: Both Stackpole parts are functionally equivalent and maintain identical electrical specifications. Selection between these two is determined by inventory availability and packaging format requirements (Tape & Reel). Both are Active status products with ROHS3 compliance and REACH Unaffected certification.

CMF554K6400FHEB Upgrade Selection: The Vishay Dale CMF554K6400FHEB is selected when circuit design requires one or more of the following conditions:

• Power dissipation exceeds 0.25W but does not exceed 0.5W
• Operating temperature range must extend above 155°C to the 175°C maximum
• Improved temperature stability is required (±50ppm/°C vs ±100ppm/°C)
• Moisture-resistant construction is specified

All three parts maintain ROHS3 compliance and are suitable for applications requiring EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can CMF554K6400FHEB replace PRNF14FTD4K64 in any application? A: Yes, the CMF554K6400FHEB is a direct functional substitute with enhanced specifications. The higher power rating (0.5W vs 0.25W) and extended temperature range (-55°C ~ 175°C vs -55°C ~ 155°C) make it suitable for all applications where PRNF14FTD4K64 is specified, provided board layout accommodates the axial package dimensions.

Q: What are the physical dimension differences between these parts? A: PRNF14FTD4K64 and RNF14FTD4K64 are 0.093" diameter × 0.250" length. CMF554K6400FHEB is 0.090" diameter × 0.240" length. These minor differences are within typical PCB hole tolerance specifications for axial through-hole components.

Q: Are there packaging format considerations when substituting? A: PRNF14FTD4K64 and RNF14FTD4K64 are supplied in Tape & Reel format. CMF554K6400FHEB is supplied in Cut Tape format. Verify that procurement and assembly processes accommodate the applicable packaging format.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Moisture Sensitivity Level is Not Applicable for all three components.

Q: When should temperature coefficient differences be considered? A: The CMF554K6400FHEB temperature coefficient of ±50ppm/°C provides superior stability compared to ±100ppm/°C for the Stackpole parts. Select CMF554K6400FHEB when circuit performance is sensitive to resistor value drift across the operating temperature range.
