Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD1K47 are classified based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• RNF14FTD1K47: Identical electrical parameters (1.47 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C). Differs only in packaging format (Cut Tape vs. Tape & Box). Suitable for direct replacement in applications where packaging format does not impose constraints.

Upgraded Substitute (Enhanced Performance Envelope):

• CMF551K4700FHEB: Maintains core electrical specifications (1.47 kOhms ±1%) with enhanced power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended maximum operating temperature (175°C vs. 155°C). Mechanical dimensions remain compatible within axial package specifications. Suitable for applications requiring higher power dissipation capability or tighter temperature stability.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD1K47 Selection Criteria: Select this substitute when packaging format flexibility is acceptable and higher inventory availability is advantageous. All electrical and mechanical specifications remain identical to the primary part. Both parts maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification).

CMF551K4700FHEB Selection Criteria: Select this upgraded substitute when circuit design permits higher power dissipation capability (0.5W vs. 0.25W) or when improved temperature stability (±50ppm/°C vs. ±100ppm/°C) is required. This part extends the maximum operating temperature to 175°C and adds moisture resistance features. All parts maintain identical RoHS and regulatory compliance status. Physical dimensions remain compatible within axial package specifications.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD1K47 be used as a direct replacement for RNF14FAD1K47? A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (1.47 kOhms ±1%, 0.25W, ±100ppm/°C). The only difference is packaging format (Cut Tape vs. Tape & Box). Direct substitution is valid for all applications where the original part is specified.

Q: What are the advantages of using CMF551K4700FHEB over the primary part? A: CMF551K4700FHEB provides enhanced power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C), and added moisture resistance. These enhancements support applications with higher thermal or environmental demands.

Q: Are all substitute parts RoHS3 compliant? A: Yes. RNF14FAD1K47, RNF14FTD1K47, and CMF551K4700FHEB are all ROHS3 compliant with REACH Unaffected status and EAR99 classification.

Q: What is the physical size difference between these parts? A: RNF14FAD1K47 and RNF14FTD1K47 share identical dimensions (0.093" Dia x 0.250" L / 2.35mm x 6.35mm). CMF551K4700FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) but remains compatible within standard axial package specifications.

Q: Which substitute should be selected for high-temperature applications? A: CMF551K4700FHEB supports operating temperatures up to 175°C compared to 155°C for the primary part, making it suitable for elevated temperature environments.

Q: Does packaging format affect electrical performance? A: No. Packaging format (Tape & Box vs. Cut Tape) does not affect electrical performance. Selection depends on procurement, handling, and assembly process requirements.
