Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08055K49FKEC is determined by the following criteria:

• Resistance value: 5.49 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• Moisture Sensitivity Level: 1

All identified substitute parts meet these core electrical and mechanical parameters. Variations in maximum seated height and specific feature designations (such as automotive AEC-Q200 versus moisture resistant) do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full compliance with ROHS3 and possess Moisture Sensitivity Level 1 rating. Selection among these alternatives should be based on:

• Availability: ERJ-6ENF5491V (Panasonic) offers the highest inventory at 65,777 units; RMCF0805FT5K49 (Stackpole) provides 18,957 units; CR0805-FX-5491ELF (Bourns) supplies 25,937 units; CRCW08055K49FKEA (Vishay Dale) stocks 1,182 units.
• Seated height constraints: CRCW08055K49FKEC and CRCW08055K49FKEA are identical at 0.50mm maximum height. ERJ-6ENF5491V reaches 0.70mm; RMCF0805FT5K49 reaches 0.65mm; CR0805-FX-5491ELF reaches 0.60mm. Applications with tight vertical clearance should prioritize the Vishay Dale variants.
• Automotive qualification: CRCW08055K49FKEC and ERJ-6ENF5491V carry explicit AEC-Q200 automotive rating. CR0805-FX-5491ELF is designated as moisture resistant. All parts meet the specified operating temperature and electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can CRCW08055K49FKEA be used as a direct replacement for CRCW08055K49FKEC?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (5.49 kOhms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package dimensions (0805, 0.50mm maximum height). The difference in part number suffix reflects packaging or manufacturing date variations that do not affect functional performance.

Q: What is the significance of the 0.20mm height difference between CRCW08055K49FKEC (0.50mm) and ERJ-6ENF5491V (0.70mm)?

A: The maximum seated height specification indicates the vertical space the component occupies on a PCB. Applications with height-constrained layouts (such as thin modules or stacked assemblies) must verify clearance before substituting ERJ-6ENF5491V. Standard PCB designs typically accommodate this variation without issue.

Q: Are all substitute parts suitable for automotive applications?

A: CRCW08055K49FKEC, CRCW08055K49FKEA, and ERJ-6ENF5491V carry explicit AEC-Q200 automotive qualification. CR0805-FX-5491ELF and RMCF0805FT5K49 meet the specified electrical and environmental parameters but do not carry explicit automotive certification in the provided data. Automotive design requirements should be verified against application specifications.

Q: Do all parts share the same RoHS and MSL compliance?

A: Yes. All listed parts are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). No special storage or handling precautions are required beyond standard component handling practices.

Q: Can these parts be mixed within a single production run?

A: All substitute parts meet identical electrical specifications and package dimensions. PCB assembly processes accommodate all listed variants without modification. However, supply chain and traceability documentation should reflect the specific manufacturer and part number used in each production batch.
