Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2941CS is determined by strict equivalence across the following parameters:

Electrical Specifications:

• Resistance value: 2.94 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Specifications:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Status: REACH Unaffected (required)

All four substitute parts listed meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (Automotive AEC-Q200 certification), and minor dimensional differences in seated height do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are Active product status components with ROHS3 compliance and REACH Unaffected designation, meeting the regulatory requirements of the original RCS2012F2941CS.

CRCW08052K94FKEA (Vishay Dale): Includes Automotive AEC-Q200 certification. Seated height is 0.020" (0.50mm), the lowest among all options. Available in Cut Tape and Digi-Reel® packaging formats.

ERJ-6ENF2941V (Panasonic Electronic Components): Includes Automotive AEC-Q200 certification. Seated height is 0.028" (0.70mm), the highest among all options. Available in Cut Tape and Digi-Reel® packaging formats. Highest inventory availability at 44,467 pieces.

RC0805FR-072K94L (YAGEO): Features moisture-resistant construction matching the original component. Seated height is 0.024" (0.60mm). Available in Tape & Reel packaging. Highest inventory availability at 155,009 pieces.

RMCF0805FT2K94 (Stackpole Electronics Inc): Includes Automotive AEC-Q200 certification. Seated height is 0.026" (0.65mm), matching the original component. Available in Tape & Reel packaging.

Selection among these substitutes depends on application requirements for automotive qualification (AEC-Q200) and packaging format preferences. All components are electrically and mechanically equivalent for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K94FKEA replace RCS2012F2941CS in any application?

A: Yes. Both components share identical electrical specifications (2.94 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), identical package dimensions (0805 / 2012 Metric), and equivalent compliance certifications (ROHS3, MSL 1). The seated height difference (0.020" vs. 0.026") is within typical PCB design tolerances for 0805 components.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape and Digi-Reel® packaging supplies components on cut tape segments, suitable for lower-volume or manual assembly operations. Electrical and mechanical properties are identical; packaging format selection depends on assembly process requirements.

Q: Does AEC-Q200 certification affect substitutability?

A: No. AEC-Q200 is an automotive qualification standard that certifies component reliability under automotive operating conditions. Components with AEC-Q200 certification (CRCW08052K94FKEA, ERJ-6ENF2941V, RMCF0805FT2K94) are suitable for automotive applications and general industrial use. The original RCS2012F2941CS without AEC-Q200 designation remains suitable for non-automotive applications. Substitution is valid in either direction based on application requirements.

Q: Are there differences in moisture resistance between substitute parts?

A: All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. The original RCS2012F2941CS specifies anti-sulfur and moisture-resistant construction. RC0805FR-072K94L explicitly lists moisture-resistant features. All parts are suitable for standard PCB assembly and storage conditions without special moisture control requirements.

Q: Can seated height variations affect PCB assembly?

A: Seated height variations among these 0805 components (0.020" to 0.028") are within standard manufacturing tolerances for this package type. PCB design clearances for 0805 components typically accommodate this range. Height differences do not affect electrical performance or standard assembly processes. Verification is recommended only for applications with specific height constraints (e.g., confined spaces, specific mechanical assemblies).

Q: Which substitute offers the best inventory availability?

A: RC0805FR-072K94L (YAGEO) offers the highest inventory at 155,009 pieces. ERJ-6ENF2941V (Panasonic) provides 44,467 pieces. Both exceed typical supply requirements for most applications.
