Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0790R9L are qualified based on the following critical parameters:

• Identical resistance value: 90.9 Ohms
• Compatible package: 1206 (3216 Metric)
• Matching power rating: 0.25W (1/4W)
• Thin film composition technology
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance requirement
• MSL 1 rating (unlimited moisture sensitivity)

The ERA-8AEB90R9V from Panasonic Electronic Components meets all substitution criteria. This part provides enhanced tolerance specification (±0.1% versus ±1%) and includes automotive AEC-Q200 qualification, making it suitable for applications requiring higher precision or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

The RT1206FRE0790R9L and ERA-8AEB90R9V are directly substitutable based on matching electrical specifications, package format, and environmental compliance requirements. Both parts are Active status components with full RoHS3 compliance and MSL 1 rating.

Selection between these parts should be based on application requirements:

• Use RT1206FRE0790R9L for general-purpose applications where ±1% tolerance is acceptable and standard industrial reliability is sufficient.
• Use ERA-8AEB90R9V for applications requiring tighter tolerance control (±0.1%), lower temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), or automotive-grade reliability certification (AEC-Q200).

Both parts are suitable for the full operating temperature range of -55°C to 155°C and maintain identical physical dimensions and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB90R9V replace RT1206FRE0790R9L in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package format, and operating temperature range. The ERA-8AEB90R9V provides enhanced tolerance and temperature coefficient specifications, making it a direct upgrade substitute.

Q: What is the physical size difference between these parts?

A: Both parts use the 1206 (3216 Metric) package. The RT1206FRE0790R9L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB90R9V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 155°C temperature range. The ERA-8AEB90R9V provides superior temperature stability with ±25ppm/°C coefficient compared to the RT1206FRE0790R9L at ±50ppm/°C.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. The ERA-8AEB90R9V additionally carries AEC-Q200 automotive qualification.

Q: Is moisture sensitivity a concern for these components?

A: No. Both parts carry MSL 1 rating, indicating unlimited moisture sensitivity level with no special storage or handling requirements.
