Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F5490CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match Exactly):

• Resistance value: 549 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of Terminations: 2
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: 0.063W (1/16W) is the baseline; 0.1W (1/10W) represents an upgrade substitute with higher power dissipation capability
• Features: Moisture Resistant or Automotive AEC-Q200 certifications are allowable enhancements

Substitute Categories:

Direct Equivalents maintain identical electrical and mechanical specifications with equivalent packaging formats (Cut Tape or Tape & Reel).

Upgrade Substitutes provide higher power rating (0.1W vs. 0.063W) while maintaining all other critical parameters, suitable for applications requiring additional thermal margin.

Similar Substitutes include automotive-grade certifications (AEC-Q200) while maintaining identical power and electrical specifications, applicable to designs requiring automotive-qualified components.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

CR0402-FX-5490GLF (Bourns Inc.) and RC0402FR-07549RL (YAGEO) are direct electrical and mechanical equivalents to the RC1005F5490CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and operating specifications. Selection between these options is determined by packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel®) and supply chain availability. Both are ROHS3 compliant with MSL 1 rating.

Upgrade Substitute Selection:

ERJ-2RKF5490X (Panasonic Electronic Components) provides an upgrade path with 0.1W power rating versus the baseline 0.063W. This component maintains all other critical electrical parameters and is qualified to Automotive AEC-Q200 standard. Selection of this upgrade is appropriate when designs require enhanced thermal margin or when automotive-grade qualification is a system requirement.

Automotive-Grade Equivalent Selection:

CRCW0402549RFKED (Vishay Dale) and RMCF0402FT549R (Stackpole Electronics Inc) are functionally equivalent to the RC1005F5490CS with the addition of Automotive AEC-Q200 certification. These components maintain identical electrical specifications and 0.063W power rating. Selection is appropriate for applications requiring automotive-qualified components or when design standards mandate AEC-Q200 compliance.

Compliance Verification:

All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-5490GLF replace RC1005F5490CS in a production assembly?

A: Yes. CR0402-FX-5490GLF is a direct electrical and mechanical equivalent. Both components share identical resistance (549 Ω), tolerance (±1%), power rating (0.063W), package dimensions (0402), and operating temperature range (-55°C ~ 155°C). The primary difference is packaging format (Tape & Reel versus Cut Tape). Verify that your assembly equipment accommodates the selected packaging format.

Q: What is the difference between the baseline RC1005F5490CS and the ERJ-2RKF5490X upgrade?

A: The ERJ-2RKF5490X provides a higher power rating of 0.1W (1/10W) compared to the baseline 0.063W (1/16W). All other electrical parameters remain identical: 549 Ω resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The upgrade also includes Automotive AEC-Q200 certification. Use the upgrade when thermal margin is required or when automotive qualification is mandated by design specifications.

Q: Are CRCW0402549RFKED and RMCF0402FT549R suitable for non-automotive applications?

A: Yes. Both components are functionally equivalent to RC1005F5490CS with the addition of Automotive AEC-Q200 certification. The certification does not restrict use to automotive applications; it indicates the component meets automotive reliability and qualification standards. These parts are suitable for any application requiring the specified electrical parameters and may be selected when automotive-grade reliability is desired regardless of application type.

Q: What packaging formats are available for these substitutes?

A: The RC1005F5490CS is supplied in Cut Tape (CT) format. Direct equivalents are available in Tape & Reel (TR) format (CR0402-FX-5490GLF, ERJ-2RKF5490X, RMCF0402FT549R) and Cut Tape & Digi-Reel® format (RC0402FR-07549RL, CRCW0402549RFKED). Verify your assembly process requirements and equipment compatibility before selecting a packaging format.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the RC1005F5490CS. No additional handling or storage procedures are required when transitioning between these components.

Q: Can I use RC0402FR-07549RL as a direct replacement without design changes?

A: Yes. RC0402FR-07549RL is a direct equivalent with identical electrical specifications (549 Ω, ±1%, 0.063W) and physical dimensions (0402 package, 0.039" L x 0.020" W). The component includes Moisture Resistant features matching the original. Packaging format options (Cut Tape & Digi-Reel®) must be verified for compatibility with your assembly process.
