Parameter Comparison

Engineering Selection Recommendations

2-2176091-0 (TE Connectivity Passive Product): This substitute offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W) in the same 0805 package. The temperature coefficient is tighter at ±25ppm/°C. Height is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the original part. ROHS3 compliant with MSL 1 rating. Suitable for applications requiring enhanced precision and thermal headroom.

ERA-6AEB90R9V (Panasonic Electronic Components): This substitute matches the original part's power rating (0.125W) and physical height (0.024"), providing a direct form-fit-function replacement. It offers improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C). Includes AEC-Q200 automotive qualification. ROHS3 compliant with MSL 1 rating. Suitable for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the 2-2176091-0 be used as a direct replacement for the RT0805FRE0790R9L?

A: Yes. Both parts share the same 90.9 Ohm resistance, 0805 package, and operating temperature range. The substitute has superior tolerance and power rating. The height difference (0.026" versus 0.024") is within typical PCB assembly tolerances for 0805 components.

Q: What is the advantage of the ERA-6AEB90R9V substitute?

A: The ERA-6AEB90R9V provides identical power rating and physical dimensions to the original part while offering tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C). It includes AEC-Q200 automotive qualification, making it suitable for automotive and mission-critical applications.

Q: Are all three parts interchangeable in the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical length and width (0.079" × 0.049"). The height variation between parts (0.024" to 0.026") is negligible for standard PCB assembly processes.

Q: What does ±0.1% tolerance mean compared to ±1%?

A: ±0.1% tolerance provides tighter resistance accuracy. For a 90.9 Ohm resistor, ±1% allows variation of ±0.909 Ohms (89.991 to 91.809 Ohms), while ±0.1% allows variation of ±0.0909 Ohms (90.8091 to 90.9909 Ohms). Tighter tolerance is beneficial in precision analog circuits.

Q: Does the AEC-Q200 rating on the ERA-6AEB90R9V affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards and is suitable for use in any application. It does not restrict use to automotive circuits.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
