Engineering Selection Recommendations

YAGEO RT0805BRD0790K9L offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package specifications. This part is suitable for applications requiring tighter resistance accuracy.

YAGEO RT0805DRD0790K9L provides intermediate tolerance (±0.5%) with improved temperature coefficient (±25ppm/°C) and maintains the same power rating and package form factor.

TE Connectivity 9-2176093-1 delivers higher power dissipation capability (0.25W vs 0.125W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part accommodates higher thermal stress applications while maintaining all other electrical and mechanical specifications.

Panasonic ERA-6AEB9092V combines ±0.1% tolerance with AEC-Q200 automotive qualification and ±25ppm/°C temperature coefficient. This part is suitable for automotive and high-reliability applications requiring automotive-grade components.

Susumu RG2012P-9092-B-T5 provides ±0.1% tolerance, AEC-Q200 automotive qualification, and anti-sulfur construction with ±25ppm/°C temperature coefficient. This part is optimized for automotive environments with enhanced corrosion resistance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range. Selection should be based on application-specific requirements for tolerance, power dissipation, automotive qualification, and environmental protection.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0790K9L replace RT0805FRE0790K9L directly? A: Yes. Both parts share identical resistance (90.9 kΩ), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). RT0805BRD0790K9L offers superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between the TE Connectivity 9-2176093-1 and the YAGEO parts? A: The primary difference is power rating: 9-2176093-1 is rated for 0.25W (1/4W) versus 0.125W (1/8W) for YAGEO parts. All other parameters—resistance, tolerance, temperature coefficient, package, and compliance—are equivalent or superior. Use 9-2176093-1 in applications requiring higher power dissipation.

Q: Are the Panasonic ERA-6AEB9092V and Susumu RG2012P-9092-B-T5 suitable for automotive applications? A: Yes. Both parts carry AEC-Q200 automotive qualification. Susumu RG2012P-9092-B-T5 additionally features anti-sulfur construction for enhanced environmental protection in automotive environments.
