CRCW08051M00FKTC Equivalent & Substitute Parts

Part Overview

The CRCW08051M00FKTC is a 1 MOhm ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This part is rated for automotive applications under AEC-Q200 and operates across -55°C to 155°C. The original part is currently active in inventory with 1131 pieces available. Substitute parts are necessary when the original packaging format (Tape & Reel with specific termination code) is unavailable, when RoHS3 compliance is required, or when alternative series with enhanced features (anti-sulfur, high voltage) are preferred for specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (1 MOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. Parts are grouped into three categories:

Direct Substitutes (Same Series, Different Packaging): CRCW08051M00FKEA, CRCW08051M00FKEB, and CRCW08051M00FKTB maintain identical electrical specifications and automotive qualification but differ in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and RoHS compliance status.

Upgrade Substitutes (Enhanced Features): RCA08051M00FKEA adds anti-sulfur protection while maintaining all core electrical parameters. RCV08051M00FKEA adds high voltage capability. Both are RoHS3 compliant and active products.

Manufacturer-Recommended Alternatives: CRCW08051M00FKEAC (CRCW-C series), RCG08051M00FKEA (RCG e3 series), and cross-manufacturer options ERJ-6ENF1004V (Panasonic), RMCF0805FG1M00, and RMCF0805FT1M00 (Stackpole) meet all electrical and mechanical specifications with AEC-Q200 qualification and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051M00FKEA be used as a direct replacement for CRCW08051M00FKTC?

A: Yes. Both parts share identical electrical specifications (1 MOhm ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and AEC-Q200 automotive qualification. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and RoHS compliance status (ROHS3 Compliant versus non-compliant). Electrical performance and mechanical fit in 0805 footprints are equivalent.

Q: What is the difference between CRCW, RCA, RCG, and RCV series resistors?

A: All four series maintain identical core electrical parameters for the 1 MOhm ±1% 0.125W 0805 specification. RCA series adds anti-sulfur protection. RCV series adds high voltage capability. RCG e3 series represents a general-purpose alternative. CRCW is the standard automotive-qualified series. Selection depends on application-specific environmental or voltage requirements.

Q: Are Panasonic ERJ-6ENF1004V and Stackpole RMCF series fully compatible with Vishay Dale CRCW08051M00FKTC?

A: Yes. All three manufacturers' parts meet the same electrical specifications (1 MOhm ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package type (0805 / 2012 Metric), and AEC-Q200 automotive qualification. Physical dimensions are equivalent, allowing direct PCB footprint compatibility. Packaging format differs (Cut Tape, Digi-Reel, or Tape & Reel), which affects handling and assembly but not electrical performance.

Q: Why would I choose RMCF0805FT1M00 over CRCW08051M00FKEA?

A: RMCF0805FT1M00 from Stackpole offers significantly higher inventory availability (888228 pieces versus 20400 pieces) and maintains identical electrical and mechanical specifications with AEC-Q200 qualification and RoHS3 compliance. Selection is driven by supply chain availability, lead time requirements, and cost considerations rather than technical performance differences.

Q: Is the height difference between parts significant for PCB assembly?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm) seated maximum. These differences are within standard 0805 package tolerances and do not affect PCB assembly compatibility. All parts are suitable for standard pick-and-place equipment and reflow soldering processes.

Q: Can I use RCV08051M00FKEA (high voltage) in place of the standard CRCW08051M00FKTC?

A: Yes. RCV08051M00FKEA maintains all core electrical specifications and exceeds the standard part's capabilities with high voltage rating. It is a functional upgrade suitable for any application where the standard part is specified, with no electrical or mechanical compatibility issues.
