Key Parameters

Substitute Part Grouping Explanation

Substitution of the CRCW08055K49FKTC is determined by strict equivalence across the following parameters: resistance value (5.49 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and moisture sensitivity level (MSL 1). All identified substitute parts maintain these electrical and mechanical specifications. Packaging format (Tape & Reel) and termination count (2) are consistent across all alternatives. Physical dimensions remain within acceptable tolerances for 0805 package specifications.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08055K49FKEA from Vishay Dale is a direct equivalent offering identical electrical and mechanical specifications with improved RoHS3 compliance status and higher inventory availability (1182 units). This part is recommended for new designs requiring regulatory compliance.

The CR0805-FX-5491ELF from Bourns Inc. is designated as manufacturer recommended and features moisture-resistant thick film composition. It maintains full electrical equivalence with ROHS3 compliance and 25937 units in stock. Seated height is 0.024".

All substitute parts are rated for AEC-Q200 automotive applications or equivalent performance standards, with MSL 1 moisture sensitivity rating and identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can CRCW08055K49FKEA be used as a direct replacement for CRCW08055K49FKTC?

A: Yes. Both parts share identical electrical specifications (5.49 kOhms ±1%, 0.125W, ±100ppm/°C) and mechanical package (0805). The primary difference is RoHS3 compliance status of the FKEA variant. Seated height is identical at 0.020".

Q: What is the significance of the height differences among substitute parts?

A: All seated heights (0.020" to 0.028") fall within the 0805 (2012 Metric) package specification tolerance. Height variation does not affect electrical performance or standard PCB assembly processes. Component selection based on height should only be considered for applications with specific spatial constraints.

Q: Are all substitute parts suitable for automotive applications?

A: The CRCW08055K49FKTC, CRCW08055K49FKEA, ERJ-6ENF5491V, and RMCF0805FT5K49 are all rated AEC-Q200 for automotive use. The CR0805-FX-5491ELF from Bourns is rated for moisture-resistant applications and maintains equivalent performance specifications.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant parts?

A: The original CRCW08055K49FKTC is RoHS non-compliant, while all substitute parts listed are ROHS3 compliant. This affects regulatory acceptance in applications subject to RoHS directives. Electrical and mechanical performance are identical.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts maintain identical resistance, tolerance, power rating, package type, and operating specifications. The 0805 package footprint is standardized across all manufacturers. Substitution does not require PCB redesign.

Q: Which substitute part offers the best inventory availability?

A: The ERJ-6ENF5491V from Panasonic Electronic Components has the highest inventory level at 65777 units, followed by CR0805-FX-5491ELF at 25937 units and RMCF0805FT5K49 at 18957 units.
