Engineering Selection Recommendations

All identified substitute parts are Active product status components with full RoHS3 compliance and REACH Unaffected designation. Selection among the RC0805FR-0761R9L (YAGEO), CRCW080561R9FKEA (Vishay Dale), ERJ-6ENF61R9V (Panasonic), and RMCF0805FT61R9 (Stackpole) is based on availability, supply chain requirements, and application-specific certifications.

The CRCW080561R9FKEA, ERJ-6ENF61R9V, and RMCF0805FT61R9 carry AEC-Q200 automotive qualification ratings, making them suitable for automotive and high-reliability applications where this certification is required. The RC0805FR-0761R9L provides a direct equivalent without automotive qualification.

Height variations among substitute parts range from 0.020" to 0.028" (0.50mm to 0.70mm), all within acceptable PCB assembly tolerances for 0805 package components. Component selection should account for specific board layout constraints if height clearance is a design consideration.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0761R9L (YAGEO) be used as a direct replacement for RC2012F61R9CS (Samsung)?

A: Yes. The RC0805FR-0761R9L matches all critical electrical parameters (61.9 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical specifications (0805 package, 2.00mm x 1.25mm), and compliance requirements (RoHS3, MSL 1, REACH Unaffected). Direct substitution is supported.

Q: What is the difference between the automotive-qualified parts and non-automotive parts?

A: The CRCW080561R9FKEA (Vishay Dale), ERJ-6ENF61R9V (Panasonic), and RMCF0805FT61R9 (Stackpole) carry AEC-Q200 automotive qualification. The RC0805FR-0761R9L (YAGEO) does not list this certification. AEC-Q200 qualification indicates compliance with automotive reliability and testing standards. Use automotive-qualified parts in applications requiring this certification.

Q: Are there height differences between substitute parts that affect PCB assembly?

A: Yes. Seated heights range from 0.020" (0.50mm) for CRCW080561R9FKEA to 0.028" (0.70mm) for ERJ-6ENF61R9V. All values fall within standard 0805 package tolerances and are compatible with standard PCB assembly processes. Height variation is not a limiting factor for interchangeability.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part RC2012F61R9CS and all substitutes, have Moisture Sensitivity Level 1 (Unlimited). This indicates no moisture sensitivity restrictions and no special storage or handling requirements.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF61R9V (Panasonic) has 94,772 pieces in stock, followed by RC0805FR-0761R9L (YAGEO) with 38,235 pieces. Both represent high availability for supply chain planning.
