Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC110R are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Resistance value: 110 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Number of terminations: 2 (exact match required)

The CMF55110R00FHEB from Vishay Dale meets all critical electrical and mechanical parameters. Physical dimensions differ slightly, but both parts maintain axial package compatibility. The substitute part extends the operating temperature range to -55°C ~ 175°C and includes moisture-resistant features, providing enhanced performance characteristics while maintaining full electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC110R and CMF55110R00FHEB are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on:

• Procurement availability and lead time requirements
• Packaging format preference (Tape & Reel versus Cut Tape)
• Physical space constraints in the application (dimensional differences noted)
• Operating temperature requirements (CMF55110R00FHEB supports extended upper temperature to 175°C)
• Moisture exposure conditions (CMF55110R00FHEB includes moisture-resistant features)

Both parts are electrically and mechanically equivalent for standard applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CMF55110R00FHEB be used as a direct replacement for RNF12FTC110R?

A: Yes. Both parts share identical electrical specifications: 110 Ohms ±1% resistance, 0.5W power rating, ±50ppm/°C temperature coefficient, and axial package configuration. Physical dimensions differ slightly, but both maintain standard axial form factor compatibility.

Q: What are the key differences between these parts?

A: The CMF55110R00FHEB offers an extended operating temperature range (-55°C to 175°C versus -55°C to 155°C) and includes moisture-resistant features. Physical dimensions are smaller (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L). Packaging differs: RNF12FTC110R is supplied in Tape & Reel format, while CMF55110R00FHEB is supplied in Cut Tape format.

Q: Are both parts RoHS compliant?

A: Yes. Both the RNF12FTC110R and CMF55110R00FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Does the dimensional difference affect circuit board layout?

A: The CMF55110R00FHEB is physically smaller in both diameter and length. In most applications, this presents no compatibility issues. However, applications with tight spatial constraints or specific mounting requirements should verify that the smaller dimensions are acceptable for the intended circuit board layout.

Q: Which part should be selected for high-temperature applications?

A: The CMF55110R00FHEB supports operation up to 175°C, compared to 155°C for the RNF12FTC110R. For applications requiring extended high-temperature performance, the CMF55110R00FHEB is the appropriate selection.
