Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07255RL is determined by the following critical parameters:

• Resistance value must equal 255 Ohms
• Package format must be 1206 (3216 Metric)
• Power rating must be 0.25W (1/4W) minimum
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance is required

The ERA-8AEB2550V qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering enhanced tolerance (±0.1% versus ±1%) and automotive-grade reliability certification (AEC-Q200). The improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) provides superior stability without compromising functional compatibility.

Parameter Comparison

The substitute offers improved tolerance specification (±0.1% versus ±1%) and enhanced temperature stability (±25ppm/°C versus ±50ppm/°C), making it appropriate for precision circuit applications. The AEC-Q200 automotive qualification of the ERA-8AEB2550V provides additional reliability assurance for demanding environments. Both parts maintain full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB2550V replace the RT1206FRE07255RL in existing designs?

A: Yes. Both parts share identical resistance value (255 Ohms), power rating (0.25W), package format (1206), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance and temperature coefficient specifications.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE07255RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB2550V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). Both dimensions remain within standard 1206 package tolerances and are compatible with typical PCB layouts.

Q: Does the improved tolerance of the ERA-8AEB2550V affect circuit performance?

A: The ERA-8AEB2550V tolerance of ±0.1% is tighter than the RT1206FRE07255RL tolerance of ±1%. This provides improved resistance accuracy and may enhance circuit performance in precision applications. No negative effects result from this specification improvement.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB2550V carries AEC-Q200 automotive qualification. The RT1206FRE07255RL does not specify automotive certification. For automotive applications, the ERA-8AEB2550V is the appropriate selection.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-8AEB2550V temperature coefficient of ±25ppm/°C is superior to the RT1206FRE07255RL coefficient of ±50ppm/°C. Lower temperature coefficient values indicate better resistance stability across the operating temperature range, beneficial for precision circuits and temperature-sensitive applications.
