Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FTC69K8 are qualified based on the following electrical and mechanical parameters:

Resistance value and tolerance must match exactly at 69.8 kOhms ±1%. Power rating must be equivalent or greater at 0.5W minimum. Composition must be metal film to ensure temperature stability and precision characteristics. Package configuration must be axial through-hole to maintain PCB layout compatibility. Temperature coefficient must be ±50ppm/°C or better to preserve circuit performance across operating conditions. Operating temperature range must encompass the minimum specification of -55°C to 155°C. Regulatory compliance including RoHS3 and REACH status must be maintained. All substitute parts must be active production items with confirmed inventory availability.

The CMF5569K800FHEB from Vishay Dale meets all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CMF5569K800FHEB includes moisture-resistant features in addition to flame retardant coating, providing enhanced environmental protection. Both parts maintain identical electrical specifications including resistance value, tolerance, power rating, and temperature coefficient. Selection between these parts should be based on application temperature requirements, environmental exposure conditions, and supply chain availability. The CMF5569K800FHEB is suitable for applications requiring extended temperature operation or enhanced moisture protection without electrical performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the CMF5569K800FHEB replace the RNF12FTC69K8 in existing designs?

A: Yes. Both parts share identical resistance value (69.8 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), temperature coefficient (±50ppm/°C), and axial package configuration. The CMF5569K800FHEB operates across a wider temperature range (-55°C to 175°C) and includes moisture-resistant features, making it electrically and mechanically compatible for direct substitution.

Q: What are the physical dimension differences between these parts?

A: The RNF12FTC69K8 measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF5569K800FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The CMF5569K800FHEB is physically smaller, which may affect PCB layout spacing but does not impact electrical performance or functional compatibility.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are active production components with flame retardant coating, safety features, and full RoHS3 compliance. The CMF5569K800FHEB provides additional moisture resistance, making it suitable for applications with enhanced environmental protection requirements.

Q: What packaging formats are available for these parts?

A: The RNF12FTC69K8 is supplied in Tape & Reel (TR) packaging. The CMF5569K800FHEB is supplied in Cut Tape (CT) packaging. Both formats are standard for through-hole component distribution and do not affect component performance or compatibility.

Q: Do these parts require any special handling or storage conditions?

A: Both parts have Moisture Sensitivity Level (MSL) listed as Not Applicable, indicating standard handling and storage conditions are sufficient. No special moisture control or baking procedures are required prior to assembly.
