- Tolerance: ±1% (exact match)
- Power rating: 0.125W minimum (0.5W variants are acceptable for higher power margin)
- Temperature coefficient: ±100ppm/°C (exact match)
- Operating temperature range: -55°C to 155°C minimum (exact match)
Mechanical Equivalence Requirements:
- Package type: 0805 (2012 Metric) (exact match)
- Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match)
- Number of terminations: 2 (exact match)
Environmental & Compliance Requirements:
- Composition: Thick Film (exact match)
- Moisture Sensitivity Level: MSL 1 (exact match)

Frequently Asked Questions (FAQ)
Q: Can I substitute RC2012F5111CS with any of the listed equivalent parts without circuit redesign?
A: Yes. CR0805-FX-5111ELF, RC0805FR-075K11L, ERJ-6ENF5111V, KTR10EZPF5111, RMCF0805FT5K11, AC0805FR-075K11L, and CRCW08055K11FKEA are electrically and mechanically equivalent. All match the 5.11 kOhms ±1% resistance, 0.125W power rating, 0805 package, and -55°C to 155°C operating temperature range. No circuit modifications are required. CRCW08055K11FKEAHP is also compatible but provides higher power rating (0.5W). CRCW08055K11FKTA is not recommended due to RoHS non-compliance.
Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?
A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-volume automated pick-and-place assembly. Cut Tape & Digi-Reel packaging supplies components on cut tape segments or smaller reel formats, suitable for lower-volume production or manual assembly. Both formats contain identical components; packaging selection depends on assembly equipment and production volume requirements.
Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?
A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and traceability standards. Parts meeting automotive qualification (ERJ-6ENF5111V, KTR10EZPF5111, RMCF0805FT5K11, AC0805FR-075K11L, CRCW08055K11FKEA) are fully compatible with non-automotive applications and provide equivalent or superior performance compared to non-qualified variants.
Q: What does MSL Level 1 (Unlimited) mean for moisture sensitivity?
A: MSL Level 1 indicates the component has unlimited shelf life without moisture bake-out requirements. The component is not sensitive to moisture absorption during storage and handling, eliminating the need for controlled humidity storage or pre-reflow baking procedures.
Q: Can CRCW08055K11FKEAHP (0.5W) be used as a direct replacement for RC2012F5111CS (0.125W)?
A: Yes. The higher power rating (0.5W versus 0.125W) provides additional thermal margin and is fully compatible. The component occupies the same 0805 package footprint and maintains identical electrical specifications. Use of the higher power rating variant does not require circuit redesign and may improve thermal performance in power-dissipative applications.
Q: Why is CRCW08055K11FKTA not recommended?
A: CRCW08055K11FKTA is marked as RoHS non-compliant and REACH Affected. This part does not meet current regulatory requirements for electronic components in most jurisdictions. New product designs should not incorporate this part. Existing designs using this part should transition to compliant alternatives.
Q: Are all listed substitutes available in the same quantity as the original RC2012F5111CS?
A: Inventory availability varies by manufacturer and distributor. RC2012F5111CS has 754 pieces in stock. Substitute parts show varying inventory levels: CR0805-FX-5111ELF (39,954 pcs), ERJ-6ENF5111V (333,883 pcs), KTR10EZPF5111 (4,181 pcs), RC0805FR-075K11L (159,128 pcs), RMCF0805FT5K11 (115,237 pcs), AC0805FR-075K11L (10,315 pcs), CRCW08055K11FKEA (5,300 pcs), CRCW08055K11FKEAC (74,182 pcs), CRCW08055K11FKEAHP (11,064 pcs), and CRCW08055K11FKTA (22,668 pcs). Verify current availability with your component supplier.
Q: What is the temperature coefficient specification and why does it matter?
A: Temperature coefficient ±100ppm/°C indicates the resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. All listed equivalents match this specification, ensuring consistent performance across the -55°C to 155°C operating range. This parameter is critical for precision analog circuits and temperature-sensitive applications.
