Key Parameters

Substitute Part Grouping Explanation

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

Electrical Specifications: Resistance value (1.82 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and termination count (2) must be identical.

Environmental Ratings: Operating temperature range (-55°C ~ 155°C) and Moisture Sensitivity Level (MSL 1) must be maintained.

Regulatory Compliance: RoHS3 compliance status and REACH classification are evaluated for application requirements.

Substitute parts are grouped into three categories based on additional features: Direct equivalents maintain identical specifications; Upgrade variants add automotive AEC-Q200 certification; Similar variants may include enhanced features such as pulse withstanding capability or alternative RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Standard Applications): RC0805FR-071K82L (YAGEO) provides direct electrical and mechanical equivalence with identical specifications and RoHS3 compliance. This part maintains the moisture resistant characteristic of the original component with higher inventory availability (72075 units).

Upgrade Selection (Automotive and Enhanced Reliability Applications): AC0805FR-071K82L (YAGEO), CRCW08051K82FKEA (Vishay Dale), ERJ-6ENF1821V (Panasonic), and RMCF0805FT1K82 (Stackpole) all include Automotive AEC-Q200 certification while maintaining identical electrical specifications and RoHS3 compliance. These variants are suitable for applications requiring automotive-grade component qualification.

Enhanced Power Handling (High-Stress Pulse Applications): CRCW08051K82FKEAHP (Vishay Dale) provides 0.5W power rating with pulse withstanding capability in the same 0805 package. This variant is applicable only when circuit design requires higher transient power dissipation capacity.

Compliance Consideration: CRCW08051K82FKTA (Vishay Dale) is RoHS non-compliant and REACH Affected. This part is suitable only for applications where RoHS3 compliance is not a regulatory requirement.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071K82L directly replace RC2012F1821CS without circuit modification? A: Yes. Both components share identical electrical specifications (1.82 kΩ ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 0805 package dimensions. Physical height difference (0.60mm vs 0.66mm) is within standard PCB assembly tolerances.

Q: What is the difference between the YAGEO RC0805FR-071K82L and AC0805FR-071K82L variants? A: AC0805FR-071K82L includes Automotive AEC-Q200 certification and is designated for automotive applications. Electrical and mechanical specifications are identical. Selection depends on application requirements for automotive qualification.

Q: Why does CRCW08051K82FKEAHP have a different power rating (0.5W vs 0.125W)? A: CRCW08051K82FKEAHP is a higher power variant with pulse withstanding capability. It is not a direct substitute for standard applications but is applicable when circuit design requires enhanced transient power handling in the same package footprint.

Q: Is CRCW08051K82FKTA suitable for new designs? A: CRCW08051K82FKTA is RoHS non-compliant and REACH Affected. It is not recommended for new designs or applications with RoHS3 compliance requirements. Use RoHS3-compliant alternatives such as CRCW08051K82FKEA instead.

Q: How do height differences affect PCB assembly compatibility? A: All substitute parts maintain 0805 package designation with maximum seated heights ranging from 0.50mm to 0.70mm. These variations are within standard PCB assembly specifications and do not affect reflow soldering or component placement processes.

Q: Which substitute part offers the highest inventory availability? A: ERJ-6ENF1821V (Panasonic) provides the highest inventory level at 134907 units with Automotive AEC-Q200 certification and RoHS3 compliance.
