Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD1K13 are qualified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Resistance value: 1.13 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Termination count: 2 (exact match required)

Allowable Variations for Substitution:

• Power rating: Equal to or greater than 0.25W
• Temperature coefficient: Equal to or lower absolute value
• Operating temperature range: Equal to or exceeding -55°C ~ 155°C
• Packaging format: Different tape/box configurations acceptable
• Manufacturer: Different manufacturers acceptable if all criteria met

The RNF14FTD1K13 qualifies as a direct substitute with identical electrical specifications and differs only in packaging format (Cut Tape vs. Tape & Box). The CMF551K1300FHEB qualifies as an upgrade substitute with enhanced power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C).

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD1K13 (Direct Substitute): This part is electrically and mechanically identical to the RNF14FAD1K13, with the only difference being the packaging format (Cut Tape instead of Tape & Box). Both parts are manufactured by Stackpole Electronics Inc, maintain active product status, and carry ROHS3 compliance. Selection of this substitute is appropriate when Cut Tape packaging is acceptable for assembly processes.

CMF551K1300FHEB (Upgrade Substitute): This Vishay Dale part provides enhanced performance characteristics including doubled power rating (0.5W vs. 0.25W), improved temperature coefficient stability (±50ppm/°C vs. ±100ppm/°C), extended operating temperature range (up to 175°C vs. 155°C), and additional moisture resistance features. This part maintains ROHS3 compliance and active product status. Selection of this upgrade is appropriate for applications requiring higher power dissipation capability, improved temperature stability, or extended thermal operating range.

All three parts maintain identical resistance value, tolerance, composition, and axial package configuration, ensuring direct functional compatibility in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD1K13 be used as a direct replacement for RNF14FAD1K13?

A: Yes. Both parts are electrically and mechanically identical with the same resistance (1.13 kOhms), tolerance (±1%), power rating (0.25W), and operating specifications. The only difference is packaging format (Cut Tape vs. Tape & Box), which does not affect circuit performance.

Q: What are the advantages of using CMF551K1300FHEB instead of RNF14FAD1K13?

A: The CMF551K1300FHEB offers three performance enhancements: (1) doubled power rating (0.5W vs. 0.25W) for applications with higher power dissipation requirements, (2) improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C) for better resistance stability across temperature variations, and (3) extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C) for high-temperature applications.

Q: Are all three parts RoHS compliant?

A: Yes. RNF14FAD1K13, RNF14FTD1K13, and CMF551K1300FHEB are all ROHS3 compliant.

Q: Can CMF551K1300FHEB be used in applications designed for RNF14FAD1K13?

A: Yes. The CMF551K1300FHEB maintains identical resistance value, tolerance, and composition. The higher power rating and improved temperature coefficient are backward compatible with designs specified for the RNF14FAD1K13, providing equal or superior performance.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging includes a protective box for storage and handling, while Cut Tape provides the component on tape without the box. Both formats contain the same component and are suitable for automated assembly processes. Selection depends on inventory management and assembly line requirements.

Q: Are there any size differences between these parts?

A: The RNF14FAD1K13 and RNF14FTD1K13 have identical dimensions (0.093" Dia x 0.250" L). The CMF551K1300FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L) due to its higher power rating design, but remains compatible with standard axial resistor footprints.
