Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0732K4L is determined by the following critical parameters:

• Resistance value: 32.4 kOhms (exact match required)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance and MSL rating compatibility

The ERA-8AEB3242V qualifies as a direct substitute because it matches all mandatory electrical and mechanical parameters. The substitute offers improved tolerance (±0.1% versus ±1%) and includes automotive AEC-Q200 qualification, representing an upgrade path for applications requiring higher precision or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

Both components maintain active product status and full RoHS3 compliance. The RT1206FRE0732K4L serves as the baseline reference for general-purpose applications. The ERA-8AEB3242V represents an upgrade option due to its tighter tolerance specification (±0.1% versus ±1%) and AEC-Q200 automotive qualification. Selection between these parts depends on application requirements: the YAGEO part is suitable for standard industrial and consumer electronics, while the Panasonic part is appropriate for automotive applications or designs requiring enhanced precision and temperature stability.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3242V replace RT1206FRE0732K4L in existing designs?

A: Yes. Both components share identical resistance values, power ratings, package dimensions, and operating temperature ranges. The ERA-8AEB3242V is mechanically and electrically compatible as a direct substitute.

Q: What are the dimensional differences between these parts?

A: The RT1206FRE0732K4L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with a maximum seated height of 0.026" (0.65mm). The ERA-8AEB3242V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with a maximum seated height of 0.028" (0.70mm). These minor variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of the tolerance difference?

A: The ERA-8AEB3242V tolerance of ±0.1% provides tighter resistance accuracy compared to the RT1206FRE0732K4L at ±1%. This difference is relevant for precision analog circuits, measurement instrumentation, or applications where component matching is critical.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB3242V carries AEC-Q200 automotive qualification. The RT1206FRE0732K4L does not specify automotive qualification. For automotive designs, the ERA-8AEB3242V is the appropriate choice.

Q: What does the temperature coefficient specification indicate?

A: The temperature coefficient describes resistance value drift across the operating temperature range. The ERA-8AEB3242V at ±25ppm/°C exhibits superior temperature stability compared to the RT1206FRE0732K4L at ±50ppm/°C, making it preferable for temperature-sensitive applications.
