Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAC5K36 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 5.36 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±50ppm/°C
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Power rating: Substitutes may have equal or higher power ratings (0.25W or greater)
• Operating temperature range: Substitutes may have equal or extended upper temperature limits
• Physical dimensions: Minor variations permitted within axial package specifications
• Features: Substitutes may include additional features (moisture resistance) without compromising base functionality

Two substitute parts meet these criteria: CMF555K3600FHEB (0.5W upgrade) and CMF505K3600FHEB (direct 0.25W equivalent), both manufactured by Vishay Dale.

Parameter Comparison

Engineering Selection Recommendations

CMF505K3600FHEB (Direct Equivalent): This Vishay Dale part provides electrical and mechanical equivalence to the RNF14FAC5K36 with identical power rating (0.25W), resistance, and tolerance specifications. The extended operating temperature range (-55°C ~ 175°C) and moisture-resistant construction offer enhanced environmental performance. Physical dimensions are smaller, which may require PCB layout verification for mechanical fit. All compliance certifications (ROHS3, REACH Unaffected, EAR99) match the original specification.

CMF555K3600FHEB (Power Upgrade): This Vishay Dale part provides a higher power rating (0.5W) while maintaining all other electrical parameters identical to the main part. The upgrade path is suitable for applications requiring increased thermal margin or higher dissipation capability. Extended operating temperature range and moisture-resistant features provide additional environmental protection. Physical dimensions are comparable to the original part. All compliance certifications align with the original specification.

Both substitute parts are active products with confirmed inventory availability and meet all mandatory electrical and compliance requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can CMF505K3600FHEB be used as a direct replacement for RNF14FAC5K36? A: Yes. Both parts share identical resistance (5.36 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and temperature coefficient (±50ppm/°C). The CMF505K3600FHEB has a smaller physical footprint and extended operating temperature range. PCB layout verification is required to confirm mechanical fit due to dimensional differences.

Q: What is the advantage of using CMF555K3600FHEB over the direct equivalent? A: CMF555K3600FHEB provides double the power rating (0.5W vs 0.25W), allowing operation with higher dissipation margins in the same circuit. This upgrade is beneficial for applications with thermal stress or where component reliability under sustained load is critical. All other electrical parameters remain identical.

Q: Are there any compatibility concerns with the substitute parts? A: Both substitute parts maintain axial package configuration and standard through-hole termination compatible with RNF14FAC5K36 footprints. CMF505K3600FHEB has reduced physical dimensions; verify PCB layout clearances. Both parts are ROHS3 compliant and REACH unaffected, matching the original specification.

Q: Do the substitute parts have different environmental ratings? A: Both CMF555K3600FHEB and CMF505K3600FHEB extend the upper operating temperature limit to 175°C (compared to 155°C for RNF14FAC5K36) and include moisture-resistant construction. These enhancements provide improved performance in humid or elevated-temperature environments without affecting standard operating conditions.

Q: What is the packaging difference between these parts? A: RNF14FAC5K36 is supplied in Tape & Box (TB) packaging. CMF555K3600FHEB is available in Cut Tape (CT) with Tape & Reel (TR) option. CMF505K3600FHEB is supplied in Cut Tape (CT). Verify packaging requirements for your procurement and assembly processes.
