CRCW06035K49FKTA Equivalent & Substitute Parts

Part Overview

The CRCW06035K49FKTA is a 5.49 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Vishay Dale. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently active in production. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility across multiple qualified suppliers is required for production resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW06035K49FKTA is determined by strict equivalence across the following parameters: resistance value (5.49 kOhms), tolerance (±1%), power rating (0.1W), package type (0603 / 1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2). All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (length and height) within the 0603 package specification, packaging format (Tape & Reel versus Cut Tape), and compliance certifications (RoHS, REACH) do not affect functional interchangeability in the circuit application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are functionally equivalent to the CRCW06035K49FKTA based on electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

For automotive applications requiring AEC-Q200 certification, CRCW06035K49FKEA (Vishay Dale), ERJ-3EKF5491V (Panasonic), and RMCF0603FT5K49 (Stackpole) maintain the same automotive qualification as the primary part. RC0603FR-075K49L (YAGEO) does not carry AEC-Q200 rating and is suitable for non-automotive applications.

For RoHS3 compliance requirements, CRCW06035K49FKEA, ERJ-3EKF5491V, RC0603FR-075K49L, and RMCF0603FT5K49 are all compliant. The primary part CRCW06035K49FKTA is RoHS non-compliant and should be replaced with a compliant substitute if regulatory requirements mandate it.

Packaging format considerations: CRCW06035K49FKEA, RC0603FR-075K49L, and RMCF0603FT5K49 are supplied in Tape & Reel format. ERJ-3EKF5491V is available in Cut Tape and Digi-Reel format, which may affect procurement and assembly processes.

Inventory availability: RMCF0603FT5K49 (1,254,462 pcs) and RC0603FR-075K49L (700,192 pcs) offer the highest stock levels, followed by ERJ-3EKF5491V (142,562 pcs) and CRCW06035K49FKEA (24,490 pcs).

Frequently Asked Questions (FAQ)

Q: Can CRCW06035K49FKEA be used as a direct replacement for CRCW06035K49FKTA?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (5.49 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C). The primary difference is RoHS compliance status and minor physical dimension variations within the 0603 package specification. CRCW06035K49FKEA is ROHS3 compliant while CRCW06035K49FKTA is not.

Q: Are ERJ-3EKF5491V and RMCF0603FT5K49 suitable for automotive applications?

A: Yes. Both ERJ-3EKF5491V (Panasonic) and RMCF0603FT5K49 (Stackpole) carry AEC-Q200 automotive qualification and meet all electrical and mechanical parameters of the primary part.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape and Digi-Reel packaging provides components on shorter tape segments or alternative reel formats. Both formats contain identical components; the difference is in procurement and assembly line compatibility.

Q: Can RC0603FR-075K49L be used in automotive applications?

A: RC0603FR-075K49L meets all electrical and mechanical specifications but does not carry AEC-Q200 automotive certification. It is suitable for non-automotive applications. For automotive designs, use CRCW06035K49FKEA, ERJ-3EKF5491V, or RMCF0603FT5K49.

Q: Are all substitute parts MSL 1 rated?

A: Yes. All parts listed, including the primary CRCW06035K49FKTA, have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling or baking requirements during storage and assembly.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient specifies the resistance change per degree Celsius across the operating temperature range. All listed parts have identical ±100ppm/°C specification, ensuring equivalent thermal stability and predictable performance across -55°C to 155°C.
