Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F3484CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (3.48 MOhms), tolerance (±1%), and power rating (0.125W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C to 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (0805/2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) ensure physical fit and solderability in existing PCB layouts.

Compliance & Environmental: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for equivalent substitution. REACH status and ECCN classification must remain consistent.

Composition: Thick film construction is required to maintain electrical and thermal characteristics.

The CRCW08053M48FKEA from Vishay Dale meets all substitution criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The CRCW08053M48FKEA qualifies as a direct equivalent substitute for the RC2012F3484CS based on matching electrical, mechanical, and compliance specifications. Both components are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes. Both maintain Moisture Sensitivity Level 1 (Unlimited) rating, eliminating special handling requirements.

The Vishay Dale CRCW08053M48FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the base specifications. The seated height difference (0.020" versus 0.026") remains within acceptable PCB assembly tolerances for 0805 package components and does not impact functional performance or mechanical fit.

Selection between these components should be based on availability, supply chain considerations, and any design-specific requirements for automotive-grade certification. Both parts are active production items with established inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08053M48FKEA replace the RC2012F3484CS in existing designs?

A: Yes. Both components share identical electrical specifications (3.48 MOhms ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C to 155°C), package dimensions (0805/2012 Metric), and compliance certifications (ROHS3, REACH Unaffected). Direct substitution is supported without circuit redesign.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW08053M48FKEA meets this additional reliability requirement, making it suitable for automotive and high-reliability applications. The Samsung RC2012F3484CS does not carry this designation but meets all base electrical and environmental specifications.

Q: Are there differences in physical dimensions that affect PCB assembly?

A: The seated height differs slightly (0.020" for Vishay versus 0.026" for Samsung). This 0.006" (0.16mm) difference is within standard PCB assembly tolerances for 0805 components and does not affect placement, soldering, or functional performance.

Q: Do both parts require special moisture handling?

A: No. Both components are rated Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity. Standard storage and handling procedures apply without special desiccant or baking requirements.

Q: What compliance certifications apply to both parts?

A: Both the RC2012F3484CS and CRCW08053M48FKEA are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. HTSUS code 8533.21.0030 applies to both components.
