Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4024CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.02 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (height-seated maximum) and manufacturer-specific series designations do not affect functional substitutability. The CRCW08054M02FKEA additionally carries AEC-Q200 automotive qualification, which represents an enhanced certification level suitable for automotive applications without compromising general-purpose use cases.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-074M02L (YAGEO): This part is a direct functional equivalent with identical electrical specifications and RoHS3 compliance. The reduced seated height (0.60mm vs. 0.66mm) provides improved PCB clearance margins. Inventory availability is significantly higher at 45,780 pieces, supporting high-volume production requirements.

CRCW08054M02FKEA (Vishay Dale): This part meets all mandatory electrical and compliance parameters while carrying AEC-Q200 automotive qualification. The lowest seated height (0.50mm) offers maximum PCB design flexibility. Selection of this part is appropriate for applications requiring automotive-grade reliability or when AEC-Q200 certification is specified in design documentation. General-purpose applications do not require this enhanced certification level.

All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes, ensuring regulatory equivalence across supply chain and export considerations.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074M02L replace RC2012F4024CS in any application?

A: Yes. Both parts share identical electrical specifications (4.02 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package format (0805), and compliance certifications (ROHS3, MSL 1). The 0.06mm difference in seated height does not affect functional performance or standard PCB assembly processes.

Q: When should CRCW08054M02FKEA be selected over the other options?

A: CRCW08054M02FKEA should be selected when design specifications explicitly require AEC-Q200 automotive qualification or when the application operates in automotive environments. For general-purpose, industrial, or consumer applications, the other two parts provide equivalent performance at potentially lower cost.

Q: Are there any PCB layout considerations when substituting these parts?

A: The three parts have different maximum seated heights: 0.66mm (Samsung), 0.60mm (YAGEO), and 0.50mm (Vishay Dale). In space-constrained designs, the Vishay Dale part provides additional clearance. Standard 0805 footprints accommodate all three parts without modification.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage, handling, or assembly.

Q: What is the difference between "Moisture Resistant" and "Automotive AEC-Q200" features?

A: Moisture Resistant is a material property indicating the thick film composition resists moisture ingress. AEC-Q200 is an automotive industry qualification standard that includes moisture resistance testing plus additional reliability and performance criteria specific to automotive applications. Both features are present in the Vishay Dale part; only moisture resistance is specified for Samsung and YAGEO parts.
