RT1206FRE07191KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07191KL is a 191 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package formats, power ratings, and operating temperature ranges are maintained while offering improved tolerance specifications or enhanced reliability certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07191KL is determined by the following mandatory parameters:

• Resistance value: 191 kOhms (exact match required)
• Package format: 1206 (3216 Metric) with 2 terminations
• Power rating: 0.25W minimum
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thin film construction
• Compliance: ROHS3 and REACH requirements

The ERA-8AEB1913V qualifies as a direct substitute by meeting all mandatory parameters while offering improved tolerance (±0.1% versus ±1%) and automotive-grade reliability certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB1913V serves as a qualified substitute for the RT1206FRE07191KL in applications where component specifications align with the mandatory parameters. Both parts maintain Active product status and full ROHS3 compliance. The substitute part offers improved tolerance performance (±0.1% versus ±1%) and automotive-grade AEC-Q200 certification, making it suitable for applications requiring enhanced precision or automotive-qualified components. Physical dimensions show minor variations within the 1206 package specification, with the substitute measuring 0.126" L versus 0.122" L and 0.028" height versus 0.026" height. These dimensional differences remain within standard 1206 package tolerances and do not preclude direct substitution in standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB1913V replace the RT1206FRE07191KL in any application?

A: The ERA-8AEB1913V qualifies as a direct substitute when the application requires a 191 kOhms ±1% (or better) thin film resistor in the 1206 package with 0.25W power rating and -55°C to 155°C operating range. The improved tolerance and automotive certification do not restrict compatibility with standard industrial or commercial applications.

Q: What are the physical compatibility considerations?

A: Both parts use the 1206 (3216 Metric) package with identical width (0.063"). The substitute is 0.004" longer (3.20mm versus 3.10mm) and 0.002" taller (0.70mm versus 0.65mm). These variations fall within standard 1206 package tolerances and present no PCB layout or assembly conflicts.

Q: How do tolerance specifications affect substitution?

A: The RT1206FRE07191KL specifies ±1% tolerance, while the ERA-8AEB1913V provides ±0.1% tolerance. The substitute's tighter tolerance is compatible with applications designed for ±1% components and provides improved precision for circuits sensitive to resistor value variation.

Q: What is the significance of the AEC-Q200 certification on the substitute part?

A: AEC-Q200 certification indicates the ERA-8AEB1913V meets automotive industry reliability and qualification standards. This certification does not restrict use in non-automotive applications and provides additional assurance of component quality and consistency.

Q: Are there temperature coefficient differences between these parts?

A: The RT1206FRE07191KL has a temperature coefficient of ±50ppm/°C, while the ERA-8AEB1913V specifies ±25ppm/°C. The substitute's lower temperature coefficient indicates superior stability across the -55°C to 155°C operating range, benefiting applications with stringent temperature performance requirements.
