Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0766R5L is determined by the following critical parameters:

• Resistance Value: Must be 66.5 Ohms (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film technology ensures performance consistency
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The ERA-8AEB66R5V qualifies as a direct substitute because it matches all critical parameters while offering enhanced tolerance (±0.1% versus ±1%) and automotive-grade certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE0766R5L and ERA-8AEB66R5V are active production components with full ROHS3 compliance and unlimited moisture sensitivity rating. The ERA-8AEB66R5V offers superior tolerance performance (±0.1% versus ±1%) and automotive-grade AEC-Q200 certification, making it suitable for applications requiring enhanced precision or automotive-qualified component specifications. The RT1206FRE0766R5L remains appropriate for general-purpose applications where standard ±1% tolerance is acceptable. Both components operate across the identical temperature range (-55°C ~ 155°C) and share identical power ratings and package footprints within acceptable mechanical tolerances.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB66R5V replace RT1206FRE0766R5L in existing designs?

A: Yes. Both components share identical resistance values (66.5 Ohms), power ratings (0.25W), package format (1206), and operating temperature ranges (-55°C ~ 155°C). The ERA-8AEB66R5V has slightly larger physical dimensions (3.20mm x 1.60mm versus 3.10mm x 1.60mm length and 0.028" versus 0.026" maximum seated height), which remain within standard 1206 package tolerances and are compatible with existing PCB layouts.

Q: What is the primary difference between these two parts?

A: The ERA-8AEB66R5V provides tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), along with automotive AEC-Q200 qualification. The RT1206FRE0766R5L is suitable for general-purpose applications where standard tolerance is acceptable.

Q: Are both parts RoHS compliant?

A: Yes. Both RT1206FRE0766R5L and ERA-8AEB66R5V are ROHS3 Compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Do these parts have identical package dimensions?

A: Both use the 1206 (3216 Metric) package. Minor dimensional variations exist within standard tolerances: RT1206FRE0766R5L measures 3.10mm x 1.60mm length and width with 0.65mm maximum seated height, while ERA-8AEB66R5V measures 3.20mm x 1.60mm with 0.70mm maximum seated height. These differences are within acceptable 1206 package specifications and do not affect PCB compatibility.

Q: Which part should be selected for automotive applications?

A: The ERA-8AEB66R5V is qualified to AEC-Q200 automotive standards and is the appropriate choice for automotive-grade applications. The RT1206FRE0766R5L is suitable for general-purpose and non-automotive applications.
