Substitute Part Grouping Explanation

Substitute parts for the RNF12FTD110R are qualified based on the following criteria:

• Identical resistance value: 110 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.5W (1/2W)
• Same composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Compatible package type: Axial through-hole
• Matching safety and flame retardant features
• ROHS3 compliance maintained
• Two terminations (axial leads)

The CMF55110R00FKEB from Vishay Dale meets all electrical and mechanical substitution criteria. Packaging format differs (Cut Tape versus Tape & Reel), and the operating temperature range extends to 175°C, providing additional thermal margin. Both parts are Active status products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTD110R and CMF55110R00FKEB are Active status products with ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application requirements and supply chain considerations:

The RNF12FTD110R is suitable for applications where Tape & Reel packaging is required for automated assembly processes and where the -55°C to 155°C operating range is sufficient.

The CMF55110R00FKEB provides extended thermal performance to 175°C and includes moisture resistant characteristics. Cut Tape packaging is appropriate for manual assembly, prototyping, or lower-volume production environments. The Vishay Dale part offers 5188 pieces in current inventory compared to 951 pieces for the Stackpole part.

Both parts satisfy identical electrical specifications and mechanical compatibility requirements for axial through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can CMF55110R00FKEB replace RNF12FTD110R in existing designs?

A: Yes. Both parts share identical electrical specifications (110 Ohms ±1%, 0.5W, ±100ppm/°C) and axial package geometry. The CMF55110R00FKEB operates across a wider temperature range (-55°C to 175°C versus -55°C to 155°C) and includes moisture resistant features, making it functionally compatible for direct substitution.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape provides individual sections of carrier tape, suitable for manual assembly, prototyping, or lower-volume production runs. Both formats contain identical components.

Q: Are the physical dimensions compatible?

A: The RNF12FTD110R measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF55110R00FKEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial through-hole components with two terminations. The CMF55 is physically smaller, which may be advantageous in space-constrained layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF12FTD110R and CMF55110R00FKEB are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0090.

Q: What is the temperature coefficient significance?

A: Both parts maintain ±100ppm/°C temperature coefficient, meaning resistance changes by approximately 0.01% per degree Celsius. This specification is identical between the two parts and determines stability across the operating temperature range.
