Part Overview

The RC1005F1131CS is a 1.13 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0402 (1005 Metric) package format. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across the temperature range of -55°C to 155°C. The component features moisture resistance and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The part is currently in active production status with 933 units available in inventory.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design requirements necessitate enhanced specifications such as automotive-grade qualification or increased power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1131CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.13 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Allowable Variation Parameters:

• Power Rating: Substitute parts may equal or exceed 0.063W (1/16W)
• Features: Substitute parts may include additional certifications (Automotive AEC-Q200) or enhanced moisture resistance
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align

Substitute parts are categorized as follows:

Direct Equivalents: Parts matching all parameters including power rating (0.063W) without additional certifications.

Upgrade Equivalents: Parts with identical electrical specifications but higher power ratings (0.1W) or automotive-grade certifications, suitable for applications requiring enhanced reliability margins.

Similar Equivalents: Parts with automotive AEC-Q200 qualification and identical electrical specifications, appropriate for automotive and high-reliability applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

CR0402-FX-1131GLF (Bourns Inc.) and RC0402FR-071K13L (YAGEO) are direct functional equivalents to the RC1005F1131CS. Both parts maintain identical electrical specifications, package format, and compliance ratings. RC0402FR-071K13L includes moisture resistance features matching the original specification. Selection between these options depends on supply availability and established procurement relationships.

Upgrade Path Selection:

ERJ-2RKF1131X (Panasonic Electronic Components) provides an upgrade path with increased power rating (0.1W versus 0.063W) and Automotive AEC-Q200 qualification. This part is suitable for applications requiring enhanced thermal margin or automotive-grade reliability assurance while maintaining all other electrical parameters.

Automotive-Grade Selection:

AC0402FR-071K13L (YAGEO), CRCW04021K13FKED (Vishay Dale), and RMCF0402FT1K13 (Stackpole Electronics Inc) are automotive-qualified alternatives with AEC-Q200 certification. These parts maintain the 0.063W power rating and are appropriate for automotive applications, industrial environments, or designs requiring enhanced component qualification documentation.

All substitute parts listed maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1131GLF be used as a direct replacement for RC1005F1131CS?

A: Yes. CR0402-FX-1131GLF matches all critical electrical parameters: 1.13 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and RoHS3 compliance. Physical dimensions and termination count are identical.

Q: What is the difference between the RC1005F1131CS and ERJ-2RKF1131X?

A: The primary difference is power rating: RC1005F1131CS is rated at 0.063W (1/16W), while ERJ-2RKF1131X is rated at 0.1W (1/10W). ERJ-2RKF1131X also includes Automotive AEC-Q200 qualification. All other electrical parameters, package format, and operating temperature range are identical. The higher power rating of ERJ-2RKF1131X provides additional thermal margin.

Q: Are automotive-qualified parts (AC0402FR-071K13L, CRCW04021K13FKED, RMCF0402FT1K13) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed the specifications required for general industrial and commercial applications. AEC-Q200 certification indicates enhanced reliability testing and quality assurance. These parts are fully compatible with non-automotive designs.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard warehouse conditions indefinitely without moisture bake-out requirements.

Q: Can I substitute RC0402FR-071K13L for RC1005F1131CS in a moisture-sensitive application?

A: Yes. RC0402FR-071K13L includes moisture resistance features and maintains MSL 1 (Unlimited) rating identical to the original part. Both components are suitable for moisture-sensitive applications without additional protective measures.

Q: What is the significance of the 0402 (1005 Metric) package designation?

A: The 0402 package is a surface mount chip resistor measuring 1.00mm length by 0.50mm width (0.039" x 0.020"). All substitute parts listed use this identical package format, ensuring mechanical compatibility with PCB footprints designed for the RC1005F1131CS without layout modifications.

Q: Are there packaging format differences among the substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) format matching the original RC1005F1131CS. CRCW04021K13FKED is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with your procurement process, as reel specifications may differ between manufacturers.

Q: How do I determine which substitute part to select for my application?

A: Selection depends on three factors: (1) supply availability and lead time, (2) application requirements (automotive-grade certification if needed), and (3) thermal margin requirements (standard 0.063W or upgraded 0.1W rating). All listed parts are electrically and mechanically compatible with the original specification.
