Engineering Selection Recommendations

YAGEO RT Series Substitutes (RT0603BRD073K09L, RT0603BRE073K09L, RT0603DRD073K09L, RT0603DRE073K09L)

These parts maintain full ROHS3 compliance and identical package geometry. Selection between these variants depends on tolerance and temperature coefficient requirements:

RT0603BRD073K09L and RT0603BRE073K09L offer ±0.1% tolerance for precision applications
RT0603DRD073K09L and RT0603DRE073K09L provide ±0.5% tolerance as a mid-grade alternative
Temperature coefficient selection (±25ppm/°C vs ±50ppm/°C) depends on thermal stability requirements

TE Connectivity 5-2176088-3

This part offers ±0.1% tolerance and higher power rating (0.167W vs 0.1W). However, it carries RoHS non-compliant status and is not recommended for applications requiring regulatory compliance. Dimension variance (1.55mm vs 1.60mm length) may affect PCB layout compatibility.

Panasonic ERA-3AEB3091V

This automotive-grade part (AEC-Q200 certified) provides ±0.1% tolerance with ±25ppm/°C temperature coefficient and full ROHS3 compliance. Suitable for applications requiring automotive qualification or enhanced reliability standards.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD073K09L directly replace RT0603FRE073K09L?

A: Yes. Both parts share identical resistance (3.09 kΩ), package (0603), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). RT0603BRD073K09L offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade with enhanced precision.

Q: What is the difference between RT0603BRE073K09L and RT0603BRD073K09L?

A: Both parts have ±0.1% tolerance and 0.1W power rating. The difference is temperature coefficient: RT0603BRE073K09L has ±50ppm/°C while RT0603BRD073K09L has ±25ppm/°C. Selection depends on thermal stability requirements in your application.

Q: Why is 5-2176088-3 marked as RoHS non-compliant?

A: The TE Connectivity part does not meet ROHS3 compliance requirements. It should only be used in applications where RoHS compliance is not mandated. Additionally, its physical dimensions (1.55mm length) differ slightly from the standard 0603 package (1.60mm), requiring PCB layout verification.

Q: Is ERA-3AEB3091V suitable for automotive applications?

A: Yes. ERA-3AEB3091V carries AEC-Q200 automotive qualification and ROHS3 compliance. It is suitable for automotive and high-reliability applications requiring certified components.

Q: Can I use a higher tolerance part (±0.5%) in place of ±1%?

A: Yes. RT0603DRD073K09L and RT0603DRE073K09L have ±0.5% tolerance, which is tighter than the original ±1%. These parts are compatible and provide improved accuracy for precision circuit requirements.

Q: What is the impact of different temperature coefficients?

A: Temperature coefficient determines resistance drift over temperature range. ±25ppm/°C (tighter) provides better stability across -55°C ~ 155°C than ±50ppm/°C. Select based on circuit sensitivity to resistance variation with temperature.
