Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RGC0805FTD549R are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 549 Ohms with ±1% tolerance, power rating of 0.125W, temperature coefficient of ±100ppm/°C, and operating temperature range of -55°C to 155°C.

Mechanical Compatibility: 0805 (2012 Metric) package with 2 terminations and maximum seated height within acceptable limits for standard PCB assembly processes.

Environmental Compliance: ROHS3 compliance and MSL 1 rating for moisture sensitivity.

All identified substitutes meet these core parameters and are available from active production lines. Additional features such as automotive AEC-Q200 qualification or moisture-resistant composition are noted where applicable but do not affect basic functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications and package dimensions required for direct PCB-level replacement of the RGC0805FTD549R. Selection among substitutes depends on application requirements:

Standard Applications: RMCF0805FT549R (Stackpole) and RC0805FR-07549RL (YAGEO) provide equivalent performance with established supply availability.

Automotive Applications: RMCF0805FT549R, CRCW0805549RFKEA, and AC0805FR-07549RL carry AEC-Q200 qualification for automotive-grade reliability requirements.

Moisture-Critical Environments: AC0805FR-07549RL and RC0805FR-07549RL include moisture-resistant composition for enhanced performance in high-humidity conditions.

All substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard lead-free assembly processes and unlimited shelf life under normal storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT549R replace RGC0805FTD549R in non-automotive applications? A: Yes. RMCF0805FT549R meets all electrical and mechanical specifications of RGC0805FTD549R. The automotive AEC-Q200 qualification is an additional feature that does not restrict use in general-purpose applications.

Q: What is the significance of the height difference between substitutes? A: All substitute parts have maximum seated heights between 0.50mm and 0.70mm, which fall within standard PCB assembly tolerances for 0805 components. Height variation does not affect electrical performance or board-level compatibility.

Q: Are moisture-resistant variants required for all applications? A: Moisture-resistant composition (AC0805FR-07549RL, RC0805FR-07549RL) is beneficial in high-humidity or condensation-prone environments. Standard variants are suitable for controlled indoor conditions with MSL 1 rating providing unlimited shelf life.

Q: Can substitutes from different manufacturers be mixed on the same board? A: Yes. All listed substitutes meet identical electrical specifications, tolerance, power rating, and package dimensions. Mixed sourcing is acceptable from a functional standpoint, though single-source procurement may simplify supply chain management.

Q: Is AEC-Q200 qualification necessary for non-automotive use? A: No. AEC-Q200 qualification indicates enhanced reliability testing and is not required for general-purpose applications. Standard variants provide equivalent electrical performance for non-automotive use cases.
