Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD2K15 are classified based on the following substitution criteria:

Direct Equivalent (Same Specifications):

• RNF14FTD2K15: Identical electrical specifications (2.15 kOhms, ±1%, 0.25W, metal film, axial package). Differs only in packaging format (Cut Tape vs. Tape & Box), maintaining full functional and mechanical compatibility.

Upgrade Equivalent (Enhanced Specifications):

• CMF552K1500FHEB: Maintains core electrical parameters (2.15 kOhms, ±1%, metal film, axial package) with enhanced power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), and moisture-resistant features. Manufactured by Vishay Dale.

All substitutes maintain identical resistance value, tolerance, composition, and axial package configuration. Mechanical dimensions remain compatible within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD2K15 Selection Criteria: Select this direct equivalent when packaging format flexibility is required. This part maintains identical electrical and thermal specifications to the RNF14FAD2K15 with significantly higher inventory availability (21218 units). Both parts carry Active product status, ROHS3 compliance, and REACH unaffected certification. The Cut Tape packaging format provides cost efficiency for high-volume applications.

CMF552K1500FHEB Selection Criteria: Select this upgrade equivalent for applications requiring enhanced thermal stability or extended operating temperature range. The ±50ppm/°C temperature coefficient provides superior frequency stability compared to the ±100ppm/°C specification of the primary part. The 0.5W power rating accommodates higher dissipation requirements while maintaining the same footprint. Moisture-resistant construction extends reliability in humid environments. This part is suitable for applications where thermal performance and environmental robustness are prioritized over cost optimization.

All three parts maintain Active product status and full regulatory compliance (ROHS3, REACH unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD2K15 be used as a direct replacement for RNF14FAD2K15? A: Yes. Both parts are electrically and mechanically identical with matching resistance (2.15 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and axial package configuration. The only difference is packaging format (Cut Tape vs. Tape & Box).

Q: What are the advantages of CMF552K1500FHEB over the primary part? A: CMF552K1500FHEB provides doubled power rating (0.5W vs. 0.25W), improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C), extended operating temperature range (-55°C to 175°C vs. -55°C to 155°C), and moisture-resistant features. These enhancements support applications with higher thermal demands or stringent environmental conditions.

Q: Are all substitute parts mechanically compatible with the original design? A: Yes. All three parts use axial package configuration with compatible through-hole terminations. Physical dimensions remain within acceptable tolerances for standard PCB footprints designed for 0.093" diameter axial resistors.

Q: Do substitute parts maintain the same compliance certifications? A: Yes. All parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 ECCN. All carry Active product status.

Q: Which part should be selected for high-volume production? A: RNF14FTD2K15 is recommended for high-volume applications due to superior inventory availability (21218 units) and identical electrical specifications to the primary part.

Q: Can CMF552K1500FHEB be used in circuits designed for 0.25W resistors? A: Yes. The higher power rating (0.5W) is backward compatible with 0.25W circuit designs. The component will operate within safe thermal limits with reduced power dissipation margin, providing additional reliability headroom.
