Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RCS2012F1154CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 1.15 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Required):

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99

All identified substitute parts meet these criteria. Variations in maximum seated height and specific feature sets (anti-sulfur vs. automotive AEC-Q200 ratings) do not affect functional substitution within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F1154CS, CRCW08051M15FKEA, ERJ-6ENF1154V, and RC0805FR-071M15L—are functionally equivalent for applications requiring a 1.15 MOhms ±1% 0.125W 0805 chip resistor. Selection among these parts is based on the following factors:

Compliance and Certification: All parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. CRCW08051M15FKEA and ERJ-6ENF1154V carry automotive AEC-Q200 ratings, suitable for automotive and high-reliability applications. RCS2012F1154CS and RC0805FR-071M15L feature moisture-resistant construction without automotive-specific qualification.

Packaging and Availability: RCS2012F1154CS is supplied in Tape & Reel with 1,026 pieces in stock. CRCW08051M15FKEA is available in Cut Tape & Digi-Reel with 15,407 pieces in stock. ERJ-6ENF1154V is supplied in Tape & Reel with 50,132 pieces in stock. RC0805FR-071M15L is supplied in Tape & Reel with 24,178 pieces in stock.

Physical Dimensions: All parts share identical length and width (0.079" x 0.049"). Maximum seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm), with all values within acceptable PCB assembly tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can CRCW08051M15FKEA replace RCS2012F1154CS in all applications?

A: CRCW08051M15FKEA is electrically and mechanically equivalent to RCS2012F1154CS. Both share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is CRCW08051M15FKEA carries AEC-Q200 automotive qualification, which is a superset of general industrial requirements. Substitution is valid for all applications where RCS2012F1154CS is specified.

Q: What is the significance of the different seated heights among these parts?

A: The maximum seated heights range from 0.020" to 0.028" (0.50mm to 0.70mm). These variations are within standard PCB assembly tolerances for 0805 components and do not affect electrical performance or mechanical fit on standard PCB layouts. Height differences may be relevant only in space-constrained applications with specific height restrictions.

Q: Are the automotive AEC-Q200 rated parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents enhanced reliability testing and quality standards. Parts meeting AEC-Q200 (CRCW08051M15FKEA and ERJ-6ENF1154V) are suitable for any application where RCS2012F1154CS is specified, including consumer, industrial, and automotive applications.

Q: What is the difference between anti-sulfur and automotive AEC-Q200 features?

A: Anti-sulfur construction (RCS2012F1154CS) provides protection against sulfur-containing environmental contaminants. Automotive AEC-Q200 qualification (CRCW08051M15FKEA and ERJ-6ENF1154V) indicates compliance with automotive industry reliability and testing standards. These are distinct feature sets; neither supersedes the other. Selection depends on application environment requirements.

Q: Can these parts be mixed in the same production batch?

A: All four parts are electrically and mechanically equivalent within specified tolerances. Mixing parts from different manufacturers in the same production batch is permissible from an electrical standpoint. However, procurement and quality control procedures should account for different part numbers, manufacturers, and packaging formats.

Q: What packaging formats are available?

A: RCS2012F1154CS, ERJ-6ENF1154V, and RC0805FR-071M15L are supplied in Tape & Reel (TR) format. CRCW08051M15FKEA is available in Cut Tape (CT) & Digi-Reel format. Tape & Reel format is standard for automated assembly processes. Cut Tape format is suitable for lower-volume or manual assembly applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts—RCS2012F1154CS, CRCW08051M15FKEA, ERJ-6ENF1154V, and RC0805FR-071M15L—are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
