Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F28R7CS are qualified based on strict equivalence of the following parameters:

• Resistance Value: 28.7 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected (exact match required)

All identified substitute parts meet these criteria. Variations in features (such as automotive AEC-Q200 certification or anti-sulfur construction) represent additional capabilities that do not disqualify substitution but may provide enhanced performance characteristics for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F28R7CS, CRCW080528R7FKEA, ERJ-6ENF28R7V, and RC0805FR-0728R7L—are Active product status and fully compliant with ROHS3, REACH, and MSL 1 requirements. Selection among these parts is determined by:

Compliance Requirements: CRCW080528R7FKEA and ERJ-6ENF28R7V carry AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RCS2012F28R7CS and RC0805FR-0728R7L do not specify AEC-Q200 but meet general industrial compliance standards.

Feature Differentiation: RCS2012F28R7CS includes anti-sulfur construction. RC0805FR-0728R7L specifies moisture resistant construction. CRCW080528R7FKEA and ERJ-6ENF28R7V specify automotive AEC-Q200 qualification. These features represent application-specific enhancements rather than substitution barriers.

Physical Dimensions: All parts share identical length and width (2.00mm x 1.25mm). Seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm), with all values within typical PCB assembly tolerances for 0805 packages.

Inventory Availability: CRCW080528R7FKEA (20,688 pcs), ERJ-6ENF28R7V (39,509 pcs), RC0805FR-0728R7L (11,422 pcs), and RCS2012F28R7CS (1,013 pcs) are all in stock.

Frequently Asked Questions (FAQ)

Q: Can CRCW080528R7FKEA replace RCS2012F28R7CS in non-automotive applications?

A: Yes. Both components share identical electrical specifications (28.7 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), package dimensions (0805), and compliance certifications (ROHS3, MSL 1, REACH Unaffected). The AEC-Q200 automotive qualification on CRCW080528R7FKEA does not restrict use in non-automotive circuits.

Q: What is the significance of the height difference between substitute parts?

A: Seated height varies from 0.020" (0.50mm) to 0.028" (0.70mm) across the four parts. These variations fall within standard 0805 package tolerances and do not affect PCB assembly compatibility or electrical performance. Verify clearance requirements for specific board designs if height-constrained applications exist.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All four components operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient, meeting high-temperature circuit requirements.

Q: Does the anti-sulfur feature of RCS2012F28R7CS provide advantages over substitute parts?

A: Anti-sulfur construction on RCS2012F28R7CS addresses corrosion in sulfur-rich environments. Substitute parts do not specify this feature. Selection depends on environmental exposure requirements. For standard industrial or consumer applications without sulfur contamination risk, this feature is not a substitution requirement.

Q: Can ERJ-6ENF28R7V be used in applications originally designed for RCS2012F28R7CS?

A: Yes. ERJ-6ENF28R7V meets all electrical and mechanical equivalence criteria. The AEC-Q200 automotive qualification represents an additional capability. Verify that the 0.028" (0.70mm) maximum seated height accommodates your PCB design constraints.

Q: What compliance certifications apply to all substitute parts?

A: All four components are ROHS3 Compliant, MSL 1 (Unlimited moisture sensitivity level), and REACH Unaffected. These certifications ensure regulatory compliance for industrial, consumer, and automotive applications.
