Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2803CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 280 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package designation: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All three substitute parts meet these criteria. Composition (Thick Film) and packaging format (Tape & Reel) are identical across all candidates.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RCS2012F2803CS and are suitable for direct replacement based on electrical and mechanical parameters.

CRCW0805280KFKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification. The seated height of 0.020" (0.50mm) is the lowest among all candidates, providing additional clearance margin in space-constrained layouts. Product status is Active with ROHS3 compliance.

ERJ-6ENF2803V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification. The seated height of 0.028" (0.70mm) is the highest among candidates. Product status is Active with ROHS3 compliance. Inventory availability is highest at 135,698 pieces.

RC0805FR-07280KL (YAGEO): This substitute features moisture-resistant characteristics matching the original part. The seated height of 0.024" (0.60mm) provides mid-range clearance. Product status is Active with ROHS3 compliance. Inventory availability is 144,529 pieces.

Selection among substitutes should be based on application-specific requirements including automotive qualification needs, PCB assembly clearance constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805280KFKEA replace RCS2012F2803CS in all applications?

A: Yes. Both components share identical electrical specifications (280 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), package designation (0805), and compliance certifications (ROHS3, MSL 1). The CRCW0805280KFKEA includes additional AEC-Q200 automotive qualification. Seated height difference (0.020" vs 0.026") is within typical PCB assembly tolerances.

Q: What is the significance of the AEC-Q200 rating on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. CRCW0805280KFKEA and ERJ-6ENF2803V carry this certification, indicating compliance with automotive reliability and performance requirements. The original RCS2012F2803CS does not list this certification. Selection of AEC-Q200 qualified parts is required only if the application demands automotive-grade components.

Q: Are there differences in moisture resistance between the substitute parts?

A: All parts carry MSL rating 1 (Unlimited), indicating equivalent moisture handling capability. The original RCS2012F2803CS and YAGEO RC0805FR-07280KL explicitly list moisture-resistant features. CRCW0805280KFKEA and ERJ-6ENF2803V do not specify this feature in their descriptions, though MSL 1 rating applies to all.

Q: How do seated height variations affect PCB assembly?

A: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm) across all parts. These variations are within standard PCB assembly tolerances and do not affect electrical performance. Height selection is relevant only for applications with strict vertical clearance constraints, such as low-profile assemblies or components mounted near other tall components.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. All substitute parts conform to the 0805 (2012 Metric) package standard with identical footprint dimensions (0.079" L x 0.049" W). No PCB layout or schematic changes are required for substitution.

Q: What inventory considerations apply to part selection?

A: YAGEO RC0805FR-07280KL offers the highest inventory (144,529 pieces), followed by Panasonic ERJ-6ENF2803V (135,698 pieces) and Vishay Dale CRCW0805280KFKEA (15,069 pieces). Inventory levels may influence lead time and supply chain continuity decisions.
