Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F5111CS are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain the following core parameters: 5.11 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. These parameters define the functional equivalence class for direct substitution.

Direct Equivalents share identical power ratings (0.063W / 1/16W), packaging format, and moisture resistance characteristics. These parts are interchangeable without circuit redesign.

Upgrade Options feature enhanced power ratings (0.1W / 1/10W) or automotive AEC-Q200 qualification. These parts exceed the original specification and are suitable for applications requiring higher reliability margins or automotive-grade components.

Similar Parts include automotive AEC-Q200 rated variants with identical electrical specifications but may include additional qualification features. These are suitable for applications with automotive or enhanced reliability requirements.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0402-FX-5111GLF (Bourns Inc.) and RC0402FR-075K11L (YAGEO) provide direct electrical and mechanical equivalence to the RC1005F5111CS. Both maintain identical power ratings, package dimensions, and temperature specifications. RC0402FR-075K11L includes moisture resistant construction matching the original part specification.

For Automotive or Enhanced Reliability Applications: ERJ-2RKF5111X (Panasonic), AC0402FR-075K11L (YAGEO), CRCW04025K11FKED (Vishay Dale), and RMCF0402FT5K11 (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards. AC0402FR-075K11L and RMCF0402FT5K11 maintain the 0.063W power rating with automotive qualification. ERJ-2RKF5111X provides upgraded 0.1W power rating with automotive qualification for applications requiring higher thermal margin.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C to 155°C). Selection should be based on application requirements, supply availability, and packaging format preferences (Tape & Reel versus Cut Tape & Digi-Reel).

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-5111GLF be used as a direct replacement for RC1005F5111CS?

A: Yes. CR0402-FX-5111GLF matches all critical electrical parameters: 5.11 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel for both) and manufacturer.

Q: What is the difference between the RC1005F5111CS and ERJ-2RKF5111X?

A: Both parts share identical resistance (5.11 kOhms), tolerance (±1%), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The ERJ-2RKF5111X features a higher power rating (0.1W versus 0.063W) and includes Panasonic's AEC-Q200 automotive qualification. The ERJ-2RKF5111X is suitable for applications requiring automotive-grade components or higher power dissipation capability.

Q: Are all substitute parts available in the same packaging format?

A: No. RC1005F5111CS and most substitutes are supplied in Tape & Reel (TR) format. RC0402FR-075K11L and CRCW04025K11FKED are available in Cut Tape (CT) & Digi-Reel format. Verify packaging requirements before selection to ensure compatibility with assembly equipment and procurement processes.

Q: Which substitute parts include moisture resistant construction?

A: RC0402FR-075K11L (YAGEO) and AC0402FR-075K11L (YAGEO) explicitly include moisture resistant features matching the RC1005F5111CS specification. All parts maintain MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity across the product line.

Q: Can I use an AEC-Q200 rated part in a non-automotive application?

A: Yes. AEC-Q200 qualification represents enhanced reliability testing and quality standards. Parts meeting AEC-Q200 (ERJ-2RKF5111X, AC0402FR-075K11L, CRCW04025K11FKED, RMCF0402FT5K11) are fully compatible with standard industrial applications and provide additional reliability margin.

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

A: The ±100ppm/°C temperature coefficient defines the maximum resistance change per degree Celsius across the operating temperature range. All listed parts maintain this specification, ensuring consistent performance across -55°C to 155°C. This parameter is critical for precision analog circuits and temperature-sensitive applications.
