Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1183CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 118 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Power Rating Consideration: Substitute parts are classified into two categories based on power dissipation:

• Direct Equivalents: 0.063W (1/16W) rating matches the main part exactly
• Upgrade Option: 0.1W (1/10W) rating provides higher power handling capability while maintaining all other electrical and mechanical specifications

All identified substitutes maintain identical resistance, tolerance, package dimensions, temperature performance, and compliance certifications. Packaging format (Tape & Reel or Cut Tape) does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (0.063W Rating): CR0402-FX-1183GLF, RC0402FR-07118KL, AC0402FR-07118KL, CRCW0402118KFKED, and RMCF0402FT118K provide complete electrical and mechanical equivalence to the RC1005F1183CS. These parts are suitable for direct substitution in applications where the original 1/16W power rating is specified. Parts with Automotive AEC-Q200 certification (AC0402FR-07118KL, CRCW0402118KFKED, RMCF0402FT118K) are qualified for automotive and high-reliability applications.

Upgrade Option (0.1W Rating): ERJ-2RKF1183X from Panasonic Electronic Components offers increased power dissipation capability (0.1W versus 0.063W) while maintaining all other electrical specifications and compliance requirements. This part is suitable for applications requiring higher thermal margin or where circuit redesign permits the use of higher-rated components. The Automotive AEC-Q200 qualification provides additional reliability assurance for demanding environments.

Packaging Considerations: Tape & Reel (TR) packaging is standard for high-volume production environments. Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume applications or mixed-component assembly. Packaging format does not affect electrical performance or mechanical fit.

Compliance and Availability: All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status. Inventory availability varies by manufacturer and distributor; CR0402-FX-1183GLF (Bourns) and ERJ-2RKF1183X (Panasonic) show highest stock levels.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR0402-FX-1183GLF for RC1005F1183CS in a moisture-sensitive application? A: CR0402-FX-1183GLF maintains MSL 1 (Unlimited) rating identical to RC1005F1183CS. However, the Bourns part does not specify moisture resistant construction in its feature set, while the Samsung part explicitly includes this feature. For applications where moisture resistance is a design requirement, RC0402FR-07118KL or AC0402FR-07118KL are preferred alternatives as they explicitly specify moisture resistant composition.

Q: What is the difference between the 0.063W and 0.1W rated parts? A: Power rating indicates maximum continuous power dissipation capability. The 0.063W (1/16W) parts are suitable for standard signal-level applications. The 0.1W (1/10W) ERJ-2RKF1183X provides higher thermal headroom and is suitable for applications with higher power dissipation requirements or where thermal margin is critical. All other electrical parameters remain identical.

Q: Are automotive-qualified parts (AEC-Q200) suitable for non-automotive applications? A: Yes. Automotive AEC-Q200 qualification indicates enhanced reliability testing and quality assurance. These parts (AC0402FR-07118KL, CRCW0402118KFKED, RMCF0402FT118K) are fully compatible with non-automotive applications and provide equivalent or superior performance compared to non-qualified alternatives.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical specifications, mechanical dimensions, and performance characteristics are identical regardless of packaging format.

Q: Can I use these substitutes in high-temperature applications? A: All identified substitutes operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. They are suitable for high-temperature applications within this specified range.

Q: What does MSL 1 (Unlimited) mean for component handling? A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to assembly.
