Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4874CS is determined by strict alignment of the following parameters:

Electrical Specifications: Resistance value (4.87 MOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and termination count (2) ensure PCB footprint compatibility.

Compliance & Environmental: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are baseline requirements. REACH status and ECCN classification must align.

Composition & Construction: Thick film construction is the specified technology. Functional features (moisture resistance or automotive qualification) may vary between substitutes without affecting core electrical performance.

The CRCW08054M87FKEA from Vishay Dale meets all electrical, mechanical, and compliance criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F4874CS and CRCW08054M87FKEA are active production components with identical electrical and mechanical specifications. Selection between these parts is based on application-specific requirements:

RC2012F4874CS (Samsung Electro-Mechanics): Features moisture-resistant thick film construction. Suitable for general industrial and consumer applications. Current inventory: 1132 pieces.

CRCW08054M87FKEA (Vishay Dale): Qualified to AEC-Q200 automotive standards. Appropriate for automotive and mission-critical applications requiring automotive-grade component certification. Current inventory: 2580 pieces.

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The seated height difference (0.026" vs 0.020") is within typical PCB assembly tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054M87FKEA replace RC2012F4874CS in any application?

A: Yes, for applications where automotive qualification is not required. Both parts share identical electrical specifications (4.87 MOhms ±1%, 0.125W), operating temperature range (-55°C ~ 155°C), and package dimensions (0805 / 2012 Metric). The CRCW08054M87FKEA includes AEC-Q200 automotive certification, which is an additional qualification not a limitation.

Q: Are there physical compatibility concerns between these substitutes?

A: No. Both components use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). The seated height difference (0.026" maximum for RC2012F4874CS vs 0.020" maximum for CRCW08054M87FKEA) is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: What determines if a part qualifies as a substitute for the RC2012F4874CS?

A: Substitutes must match the following parameters: 4.87 MOhms resistance, ±1% tolerance, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, thick film composition, 2 terminations, ROHS3 compliance, and MSL 1 rating.

Q: Does the moisture-resistant feature of the RC2012F4874CS differ from the automotive qualification of the CRCW08054M87FKEA?

A: These are distinct functional features. Moisture resistance addresses environmental protection in humid conditions. AEC-Q200 automotive qualification certifies reliability under automotive operating and stress conditions. Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent moisture handling capability.

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

A: Yes. Both RC2012F4874CS and CRCW08054M87FKEA are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
