Substitute Part Grouping Explanation

Substitute parts for the RNF14FTD1K69 are identified based on the following criteria:

• Identical resistance value: 1.69 kOhms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical package type: Axial
• Identical termination count: 2
• Compliance with ROHS3 and REACH requirements
• Axial through-hole form factor compatibility

The CMF551K6900FHEB qualifies as a substitute based on these parameters. While this part features a higher power rating (0.5W vs 0.25W) and improved temperature coefficient (±50ppm/°C vs ±100ppm/°C), these represent enhanced performance characteristics that maintain backward compatibility in applications designed for the RNF14FTD1K69.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD1K69 and CMF551K6900FHEB meet ROHS3 compliance and REACH requirements. The CMF551K6900FHEB provides enhanced performance through higher power dissipation capability and improved temperature stability. Selection between these parts depends on application power requirements and thermal environment specifications. Both components are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Can the CMF551K6900FHEB replace the RNF14FTD1K69 in existing designs?

Yes. Both parts share identical resistance (1.69 kOhms), tolerance (±1%), composition (metal film), and axial package configuration. The substitute part features higher power rating and extended operating temperature range, making it suitable for applications originally specified for the RNF14FTD1K69.

What are the physical dimension differences between these parts?

The RNF14FTD1K69 measures 0.093" diameter by 0.250" length. The CMF551K6900FHEB measures 0.090" diameter by 0.240" length. Both dimensions fall within standard axial resistor form factors and are compatible with typical PCB layouts designed for 1/4W and 1/2W axial resistors.

Are there compliance differences between these parts?

No. Both parts are ROHS3 compliant and REACH unaffected. Both carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

What is the significance of the temperature coefficient difference?

The CMF551K6900FHEB features a ±50ppm/°C temperature coefficient compared to the RNF14FTD1K69 at ±100ppm/°C. This represents improved temperature stability in the substitute part, resulting in more consistent resistance values across the operating temperature range.

Can the RNF14FTD1K69 be used where the CMF551K6900FHEB is specified?

Application-dependent. The RNF14FTD1K69 has lower power rating (0.25W vs 0.5W) and narrower operating temperature range (-55°C to 155°C vs -55°C to 175°C). Use only if application power dissipation and thermal requirements fall within these specifications.
