Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4424CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 4.42 MOhms
• Tolerance: ±1%
• Power Rating: 0.125W (1/8W)
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Allowable Variation Parameters:

• Temperature Coefficient: ±100ppm/°C to ±200ppm/°C (within acceptable tolerance drift)
• Height - Seated (Max): 0.020" to 0.026" (within 0805 package specification)
• Packaging Format: Cut Tape (CT) or Tape & Reel (TR)
• Features: Moisture Resistant or Automotive AEC-Q200 rated

All identified substitute parts meet these criteria and are classified as Active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RC2012F4424CS (Samsung Electro-Mechanics) - Primary Specification

This part serves as the baseline reference. Selection is appropriate for general industrial applications requiring moisture-resistant thick film construction with standard tolerance performance. Active product status ensures continued availability and manufacturing support.

RMCF0805FT4M42 (Stackpole Electronics Inc) - Upgrade Substitute

This part is classified as an upgrade substitute due to automotive-grade AEC-Q200 qualification. The temperature coefficient specification of ±200ppm/°C represents a wider tolerance band compared to the primary part (±100ppm/°C), which remains within acceptable substitution parameters for most circuit applications. Tape & Reel packaging format provides advantages for high-volume automated assembly operations. Active product status and full ROHS3/REACH compliance confirm suitability for direct substitution.

CRCW08054M42FKEA (Vishay Dale) - Similar Substitute

This part is classified as a similar substitute with automotive-grade AEC-Q200 qualification matching the Stackpole option. The temperature coefficient specification of ±100ppm/°C aligns with the primary part, providing equivalent tolerance performance. The seated height specification of 0.020" (0.50mm) is lower than the primary part's 0.026" (0.65mm), remaining within 0805 package dimensional tolerances and suitable for space-constrained PCB layouts. Tape & Reel packaging and Active product status confirm full substitution eligibility.

All three parts maintain identical electrical performance across resistance, tolerance, power rating, and operating temperature specifications. Selection between substitutes depends on packaging format requirements, supply chain availability, and application-specific automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT4M42 replace RC2012F4424CS in all applications?

A: Yes, RMCF0805FT4M42 is electrically and mechanically compatible. The ±200ppm/°C temperature coefficient is wider than the primary part's ±100ppm/°C specification but remains within acceptable tolerance drift for standard circuit applications. Automotive AEC-Q200 qualification provides additional reliability assurance. Verify packaging format compatibility with your assembly process (Tape & Reel vs. Cut Tape).

Q: What is the difference between the Stackpole and Vishay Dale substitutes?

A: Both RMCF0805FT4M42 and CRCW08054M42FKEA are automotive-qualified alternatives. The primary difference is temperature coefficient (±200ppm/°C vs. ±100ppm/°C) and seated height (0.026" vs. 0.020"). The Vishay Dale part offers tighter temperature coefficient matching and lower profile for space-constrained designs. Both are available in Tape & Reel format.

Q: Are there packaging format considerations for substitution?

A: Yes. The primary part RC2012F4424CS is supplied in Cut Tape (CT) format, while both substitutes are supplied in Tape & Reel (TR) format. Verify your assembly equipment compatibility. TR format is standard for automated pick-and-place operations, while CT format is suitable for manual or semi-automated assembly.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. All operate across -55°C to 155°C temperature range with identical electrical specifications (4.42 MOhms ±1%, 0.125W).

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, all three parts are mechanically and electrically interchangeable. The 0805 (2012 Metric) package footprint is identical across all parts. The height variation (0.020" to 0.026") is within standard package tolerance and does not affect PCB assembly compatibility.

Q: Which part should I select for automotive applications?

A: Both RMCF0805FT4M42 and CRCW08054M42FKEA carry AEC-Q200 automotive qualification. The primary part RC2012F4424CS does not specify automotive qualification. For automotive applications, select either Stackpole or Vishay Dale substitute based on temperature coefficient requirements and availability.
