RC2012F8254CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F8254CS is an 8.25 MOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component operates at 0.125W (1/8W) power rating with moisture-resistant construction and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component requirements, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F8254CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 8.25 MOhms (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)

Critical Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 Compliant status (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All identified substitute parts meet these criteria. Variations in physical height dimensions and specific feature sets (such as automotive AEC-Q200 qualification) do not disqualify substitution when all electrical and core mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-078L (YAGEO): This substitute part is a direct equivalent with identical electrical specifications and core mechanical parameters. All compliance certifications (ROHS3, REACH Unaffected) match the original component. The seated height is 0.024" (0.60mm), which is lower than the original 0.026" (0.66mm), presenting no functional constraint for standard PCB assembly. Product status is Active with 7693 units in stock.

CRCW08058M25FKEA (Vishay Dale): This substitute part meets all critical electrical and mechanical requirements with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The component carries AEC-Q200 automotive qualification, which represents an additional feature beyond the original specification. The seated height is 0.020" (0.50mm), the lowest of the three options, and presents no functional constraint. Product status is Active with 21091 units in stock. ROHS3 and REACH Unaffected compliance are confirmed.

Both substitute parts are suitable for direct replacement based on electrical equivalence, mechanical compatibility, and regulatory compliance. Selection between them depends on supply chain availability, cost considerations, and whether automotive-grade qualification (AEC-Q200) is required for the application.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-078M25L replace RC2012F8254CS in all applications?

A: Yes. RC0805FR-078M25L meets all critical electrical parameters (8.25 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical specifications (0805 package, 2 terminations), and compliance requirements (ROHS3, REACH Unaffected, MSL 1). The lower seated height (0.60mm vs. 0.66mm) does not affect functionality.

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

A: Both parts are electrically and mechanically equivalent to the original RC2012F8254CS. The primary difference is that CRCW08058M25FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. The Vishay Dale part also has a lower seated height (0.50mm). Both are ROHS3 compliant and REACH Unaffected.

Q: Are there any height restrictions when using these substitutes?

A: The substitute parts have lower or equal seated heights compared to the original component (0.60mm and 0.50mm versus 0.66mm). This presents no constraint for standard PCB assembly. If the original design has specific height limitations, the lower profile of the substitutes is advantageous.

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

A: Yes. All three parts—RC2012F8254CS, RC0805FR-078M25L, and CRCW08058M25FKEA—have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Can I use CRCW08058M25FKEA in non-automotive applications?

A: Yes. CRCW08058M25FKEA meets all electrical and mechanical requirements for the RC2012F8254CS and is suitable for any application within the specified operating parameters. The AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. RC2012F8254CS, RC0805FR-078M25L, and CRCW08058M25FKEA are all supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.
