Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08052R55FNEA is determined by the following critical parameters: resistance value (2.55 Ohms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts match these core electrical and mechanical specifications. Variations in temperature coefficient, height-seated maximum, and specific feature designations (automotive AEC-Q200 versus moisture resistant) do not disqualify substitution when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance with MSL 1 rating. CRCW08052R55FKEA (Vishay Dale upgrade variant) offers improved temperature coefficient performance at ±100ppm/°C compared to the original ±200ppm/°C specification, with identical height-seated maximum of 0.020" (0.50mm). RMCF0805FT2R55 (Stackpole Electronics) and RC0805FR-072R55L (YAGEO) provide direct functional equivalence with standard ±200ppm/°C temperature coefficient. Height-seated maximum values for RMCF0805FT2R55 (0.026") and RC0805FR-072R55L (0.024") remain within acceptable mechanical tolerances for 0805 package applications. Selection should be based on availability, lead time requirements, and specific application constraints related to board clearance or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052R55FKEA replace CRCW08052R55FNEA in all applications? A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (2.55 Ohms ±1%, 0.125W, 0805 package). The FKEA variant features improved temperature coefficient (±100ppm/°C versus ±200ppm/°C), making it suitable for applications requiring tighter thermal stability.

Q: Are there mechanical compatibility concerns with RMCF0805FT2R55? A: RMCF0805FT2R55 has a maximum seated height of 0.026" (0.65mm) compared to 0.020" (0.50mm) for the original part. This 0.006" difference must be evaluated against board layout and component clearance requirements.

Q: What is the difference between automotive AEC-Q200 and moisture resistant designations? A: CRCW08052R55FNEA and RMCF0805FT2R55 carry AEC-Q200 automotive qualification. RC0805FR-072R55L is designated as moisture resistant. Both certifications meet ROHS3 and MSL 1 requirements. Selection depends on application environment and qualification requirements.

Q: Do all substitute parts support the same operating temperature range? A: Yes. All listed parts operate from -55°C to 155°C, ensuring thermal compatibility across the specified range.

Q: Is packaging format consistent across all substitute parts? A: All substitute parts are supplied in Tape & Reel (TR) format, maintaining supply chain consistency with the original CRCW08052R55FNEA.
