• Identical resistance value: 1.18 kOhms
• Identical package: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

The ERA-8AEB1181V provides enhanced tolerance (±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 ERA-8AEB1181V is a direct substitute for the RT1206FRE071K18L in applications where the identical package, resistance value, power rating, and operating temperature range are required. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Selection between these parts should be based on:

• Tolerance requirements: The ERA-8AEB1181V offers ±0.1% tolerance compared to ±1%, suitable for precision analog circuits
• Temperature stability: The ERA-8AEB1181V provides ±25ppm/°C temperature coefficient versus ±50ppm/°C, beneficial for temperature-sensitive applications
• Automotive applications: The ERA-8AEB1181V carries AEC-Q200 qualification for automotive-grade reliability
• Inventory and lead time considerations

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB1181V replace the RT1206FRE071K18L in existing designs?

A: Yes. Both parts share identical resistance value, package, power rating, composition, and operating temperature range. Physical dimensions are compatible within standard PCB assembly tolerances.

Q: What are the dimensional differences between these parts?

A: The RT1206FRE071K18L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB1181V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). These differences are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Is the ERA-8AEB1181V suitable for automotive applications?

A: Yes. The ERA-8AEB1181V carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The RT1206FRE071K18L does not carry this certification.

Q: What is the difference in tolerance between these parts?

A: The RT1206FRE071K18L has ±1% tolerance, while the ERA-8AEB1181V has ±0.1% tolerance. The ERA-8AEB1181V provides tighter tolerance control for precision applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RT1206FRE071K18L and ERA-8AEB1181V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
