Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD9K76 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 9.76 kOhms (exact match required)
• Tolerance: ±1% (maintains precision specifications)
• Composition: Metal Film (ensures performance characteristics)

Mechanical & Environmental Compatibility:

• Package type: Axial (physical form factor)
• Power rating: Equal to or greater than 0.25W
• Operating temperature range: Must encompass -55°C ~ 155°C minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

Packaging Format Flexibility: Substitutes may differ in packaging format (Tape & Reel vs. Tape & Box vs. Cut Tape) without affecting electrical performance, provided all other parameters remain equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD9K76 (Direct Substitute): This part maintains identical electrical specifications and operating parameters as the RNF14FAD9K76. The only difference is packaging format (Tape & Reel vs. Tape & Box), which does not affect component performance. Selection of this substitute is appropriate when Tape & Reel packaging is preferred for automated assembly processes. Both parts carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected).

CMF559K7600FHEB (Upgrade Substitute): This Vishay Dale component provides enhanced performance characteristics while maintaining electrical equivalence. The 0.5W power rating provides 100% additional power dissipation capacity compared to the 0.25W rating of the primary part. The temperature coefficient is improved (±50ppm/°C vs. ±100ppm/°C), and the operating temperature range is extended to 175°C. Moisture resistance is an additional feature. This part is suitable for applications requiring higher thermal margin or extended environmental performance. All compliance requirements (ROHS3, REACH) are met.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD9K76 be used as a direct replacement for RNF14FAD9K76? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only (Tape & Reel vs. Tape & Box). Electrical performance, tolerance, power rating, and operating temperature range are identical.

Q: What are the advantages of using CMF559K7600FHEB over the primary part? A: The CMF559K7600FHEB offers three performance enhancements: doubled power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), and extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C). Moisture resistance is also included.

Q: Are all three parts compatible with the same PCB footprint? A: Yes. All three parts use axial package configuration with identical lead spacing and mechanical dimensions suitable for standard through-hole assembly. Physical board layout compatibility is maintained across all substitutes.

Q: Do packaging format differences affect electrical performance? A: No. Tape & Box, Tape & Reel, and Cut Tape formats are packaging and delivery methods only. They do not affect component electrical characteristics, performance, or reliability.

Q: Are all substitute parts RoHS3 compliant? A: Yes. RNF14FAD9K76, RNF14FTD9K76, and CMF559K7600FHEB are all ROHS3 Compliant and REACH Unaffected.

Q: Which substitute should be selected for high-temperature applications? A: CMF559K7600FHEB supports operating temperatures up to 175°C, compared to 155°C for the primary part and RNF14FTD9K76. This part is appropriate for applications requiring extended thermal performance.

Q: Can CMF559K7600FHEB be used in applications designed for 0.25W resistors? A: Yes. The higher power rating (0.5W) is a performance enhancement that does not create compatibility issues. The component will operate safely in circuits designed for lower power dissipation.
