Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F5493CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters for Substitution:

• Resistance value: 549 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Parameters Allowing Variation:

• Power Rating: Substitutes may equal or exceed 0.063W
• Manufacturer: Different manufacturers permitted
• Features: Additional certifications (AEC-Q200) permitted without restriction
• Height variation: Within 0.016" (0.40mm) maximum seated height specification

All substitute parts listed maintain identical electrical performance and mechanical compatibility with the original RC1005F5493CS specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications): CR0402-FX-5493GLF (Bourns Inc.) and RC0402FR-07549KL (YAGEO) are direct functional equivalents to the RC1005F5493CS. Both maintain identical electrical parameters, power rating, package dimensions, and environmental ratings. These parts are suitable for one-to-one replacement in existing designs.

Upgrade Option (Enhanced Power Rating): ERJ-2RKF5493X (Panasonic Electronic Components) provides identical electrical specifications with increased power rating of 0.1W (1/10W) versus the original 0.063W. This part includes Automotive AEC-Q200 certification. The higher power rating provides additional thermal margin in applications where power dissipation may approach component limits.

Enhanced Compliance Options (AEC-Q200 Rated): AC0402FR-07549KL (YAGEO), CRCW0402549KFKED (Vishay Dale), and RMCF0402FT549K (Stackpole Electronics Inc) all maintain identical specifications to the original part while adding Automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade component reliability. AC0402FR-07549KL additionally includes moisture resistant construction matching the original design.

All substitute parts listed are Active status products with ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-5493GLF replace RC1005F5493CS in existing circuit boards? A: Yes. CR0402-FX-5493GLF is a direct equivalent with identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. No circuit modifications are required.

Q: What is the difference between the original part and ERJ-2RKF5493X? A: ERJ-2RKF5493X has a higher power rating of 0.1W compared to the original 0.063W, and includes Automotive AEC-Q200 certification. All other electrical and mechanical specifications are identical. The higher power rating provides additional thermal capability without affecting circuit performance.

Q: Are the AEC-Q200 rated substitutes suitable for non-automotive applications? A: Yes. AEC-Q200 certification indicates enhanced reliability testing and qualification standards. Parts meeting AEC-Q200 are fully compatible with non-automotive applications and provide equivalent or superior performance to non-certified alternatives.

Q: Does package dimension variation exist among the substitute parts? A: All substitute parts use the 0402 (1005 Metric) package. Height variation exists within specification: most parts have maximum seated height of 0.016" (0.40mm), while AC0402FR-07549KL has 0.015" (0.37mm). Both values are within acceptable PCB assembly tolerances and do not affect component placement or functionality.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification applies to all listed parts and the original RC1005F5493CS, eliminating moisture-related supply chain constraints.

Q: Can I use CRCW0402549KFKED which is supplied in Cut Tape (CT) & Digi-Reel® packaging instead of Tape & Reel (TR)? A: CRCW0402549KFKED is electrically and mechanically identical to the original part. Packaging format (Cut Tape vs. Tape & Reel) affects supply chain logistics and automated assembly compatibility, not component performance. Verify your assembly equipment supports the selected packaging format.

Q: Are all substitute parts in active production status? A: Yes. All substitute parts listed maintain Active product status, ensuring continued availability and supply chain stability for production and replacement applications.
