Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC1K13 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 1.13 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C

Mechanical Parameters (Must Match):

• Package type: Axial through-hole
• Number of terminations: 2

Allowable Variations:

• Power rating: Equal or greater than 0.25W
• Operating temperature range: Equal or greater than -55°C ~ 155°C
• Physical dimensions: Variations permitted if axial package compatibility is maintained

Compliance Requirements:

• RoHS3 Compliant
• Active product status

Two substitute parts meet these criteria: CMF551K1300FHEB (0.5W upgrade) and CMF501K1300FHEB (direct 0.25W equivalent).

Parameter Comparison

Engineering Selection Recommendations

CMF501K1300FHEB (Direct Equivalent): This Vishay Dale part provides identical electrical specifications and power rating to the RNF14FTC1K13. Both components are rated at 0.25W with matching resistance, tolerance, and temperature coefficient values. The operating temperature range extends to 175°C compared to 155°C for the original part. Physical dimensions are smaller, which may provide layout advantages in space-constrained applications. This part is recommended for direct substitution where packaging format (Cut Tape vs. Tape & Reel) is acceptable.

CMF551K1300FHEB (Power Upgrade): This Vishay Dale part maintains all electrical specifications while providing double the power rating at 0.5W. The extended operating temperature range to 175°C and moisture-resistant features provide enhanced performance margins. Physical dimensions are comparable to the original part. This substitution is appropriate for applications where increased power dissipation capability or enhanced environmental protection is beneficial. All parts maintain ROHS3 compliance and active production status.

Frequently Asked Questions (FAQ)

Q: Can CMF501K1300FHEB be used as a direct replacement for RNF14FTC1K13?

A: Yes. Both parts share identical resistance (1.13 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and temperature coefficient (±50ppm/°C). The operating temperature range of CMF501K1300FHEB extends to 175°C, exceeding the original specification of 155°C. Axial package compatibility is maintained. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and slightly smaller physical dimensions.

Q: What is the difference between CMF551K1300FHEB and CMF501K1300FHEB?

A: The primary difference is power rating. CMF551K1300FHEB is rated at 0.5W (1/2W), while CMF501K1300FHEB is rated at 0.25W (1/4W), matching the original RNF14FTC1K13. Both maintain identical electrical parameters. CMF551K1300FHEB provides increased power dissipation capability and is suitable for applications requiring higher thermal performance.

Q: Are physical dimensions critical for substitution?

A: Physical dimensions vary among the three parts. CMF501K1300FHEB is significantly smaller (0.065" Dia x 0.150" L) compared to RNF14FTC1K13 (0.093" Dia x 0.250" L). CMF551K1300FHEB dimensions are comparable (0.090" Dia x 0.240" L). Axial package compatibility is maintained across all parts. PCB layout and mechanical clearance requirements should be evaluated for your specific application.

Q: Do all substitute parts meet compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts maintain active production status.

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

A: RNF14FTC1K13 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Both substitute parts are supplied in Cut Tape (CT) format, which provides individual component access. Packaging format selection depends on assembly methodology and inventory management requirements.
