Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC10K2 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 10.2 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C
• Package Type: Axial
• RoHS Compliance: ROHS3 Compliant

Allowable Variations:

• Power rating may be equal or higher (0.25W or greater)
• Operating temperature range may be equal or extended
• Physical dimensions may vary within axial package constraints
• Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical equivalence

Two substitute parts meet these criteria: CMF5510K200FHEB (0.5W upgrade) and CMF5010K200FHEB (direct 0.25W equivalent).

Parameter Comparison

Engineering Selection Recommendations

CMF5010K200FHEB (Direct Equivalent): This part is electrically and mechanically equivalent to the RNF14FTC10K2, with identical resistance, tolerance, power rating, and temperature coefficient. The primary difference is the smaller physical dimension (0.065" Dia x 0.150" L versus 0.093" Dia x 0.250" L), which provides space savings in compact designs. Both parts are ROHS3 compliant and rated for the same operating temperature range of -55°C to 175°C. This substitute is suitable for direct replacement in applications where PCB layout permits the smaller form factor.

CMF5510K200FHEB (Power Upgrade): This part provides a higher power rating of 0.5W (1/2W) while maintaining all other electrical specifications identical to the main part. The extended operating temperature range (-55°C to 175°C) and moisture-resistant features provide enhanced reliability in demanding environments. This substitute is appropriate for applications where thermal margin or environmental protection is a design consideration, or where component consolidation across multiple power ratings is desired. The larger physical dimension (0.090" Dia x 0.240" L) requires verification of PCB layout compatibility.

Both substitute parts maintain ROHS3 compliance and are manufactured by Vishay Dale, an established supplier with high inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CMF5010K200FHEB be used as a direct replacement for RNF14FTC10K2? A: Yes. Both parts have identical electrical specifications: 10.2 kOhms ±1%, 0.25W power rating, ±50ppm/°C temperature coefficient, and metal film composition. The primary consideration is physical dimension; CMF5010K200FHEB is smaller (0.065" Dia x 0.150" L) and must fit within the available PCB space.

Q: What is the advantage of using CMF5510K200FHEB over the original part? A: CMF5510K200FHEB provides a higher power rating (0.5W versus 0.25W) and an extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). These characteristics offer increased thermal headroom and environmental protection. However, the larger physical dimension must be accommodated in the circuit layout.

Q: Are all three parts RoHS compliant? A: Yes. RNF14FTC10K2, CMF5510K200FHEB, and CMF5010K200FHEB are all ROHS3 compliant.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance? A: No. Packaging format is a logistics and assembly consideration only. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Can CMF5510K200FHEB be used in applications designed for 0.25W resistors? A: Yes. A higher power-rated component is electrically compatible with applications designed for lower power ratings. The 0.5W rating provides additional thermal margin without affecting circuit operation.

Q: What are the physical dimension constraints for PCB layout? A: RNF14FTC10K2 measures 0.093" Dia x 0.250" L. CMF5010K200FHEB measures 0.065" Dia x 0.150" L (smaller, suitable for compact designs). CMF5510K200FHEB measures 0.090" Dia x 0.240" L (comparable to the original). Verify available PCB space before selection.
