Parameter Comparison

Engineering Selection Recommendations

CMF5560K400FHEB (Upgrade Option): This substitute provides increased power dissipation at 0.5W while maintaining identical electrical specifications. The extended operating temperature range to 175°C and moisture-resistant construction offer enhanced reliability margins. Selection is appropriate for applications where thermal headroom is beneficial or where environmental moisture exposure is a consideration. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained.

CMF5060K400FHEB (Direct Equivalent): This substitute matches the original 0.25W power rating and provides identical electrical performance with enhanced moisture resistance. The extended operating temperature range to 175°C and moisture-resistant features provide additional environmental protection. This option is suitable for direct replacement in existing designs without thermal or environmental modifications. Full compliance status is equivalent to the original part.

Both substitute parts maintain active production status and demonstrate superior inventory availability compared to the RNF14FTC60K4, supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CMF5560K400FHEB be used as a direct replacement for RNF14FTC60K4?

A: Yes. The CMF5560K400FHEB maintains identical resistance (60.4 kOhms), tolerance (±1%), composition (metal film), package type (axial), and temperature coefficient (±50ppm/°C). The increased power rating (0.5W vs. 0.25W) is a non-limiting parameter that provides additional thermal capability without affecting circuit operation.

Q: What is the difference between CMF5560K400FHEB and CMF5060K400FHEB?

A: Both parts are electrically identical to the original RNF14FTC60K4. The primary difference is power rating: CMF5560K400FHEB is rated at 0.5W (1/2W), while CMF5060K400FHEB is rated at 0.25W (1/4W), matching the original specification. Both offer moisture-resistant construction and extended temperature range to 175°C.

Q: Are there physical dimension differences between these parts?

A: Yes. The RNF14FTC60K4 measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). The CMF5560K400FHEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). The CMF5060K400FHEB measures 0.065" Dia x 0.150" L (1.65mm x 3.81mm). These dimensional variations are typical for different power ratings in axial resistor designs and do not affect electrical substitution compatibility.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is not applicable to all parts.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For designs requiring the original 0.25W specification, CMF5060K400FHEB provides direct equivalence with enhanced moisture resistance. For applications where thermal margin is beneficial, CMF5560K400FHEB offers 0.5W capability. Both are active production parts with superior inventory availability.
