RT1206FRE079K31L Equivalent & Substitute Parts

Part Overview

The RT1206FRE079K31L is a 9.31 kOhms ±1% thin film chip resistor manufactured by YAGEO in 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative components may be required due to inventory constraints, design upgrades for improved tolerance specifications, or automotive-grade certification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE079K31L is determined by the following critical parameters:

• Resistance value: Must be 9.31 kOhms
• 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 support -55°C to 155°C minimum
• Termination count: Must be 2 terminations
• RoHS compliance: Must meet ROHS3 standard

The ERA-8AEB9311V qualifies as a direct substitute based on these parameters. While it offers improved tolerance (±0.1% versus ±1%) and automotive AEC-Q200 certification, these represent enhancements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE079K31L and ERA-8AEB9311V meet the core electrical and mechanical requirements for 9.31 kOhms thin film resistor applications in 1206 package format. Selection between these components should be based on the following factors:

The RT1206FRE079K31L is suitable for general-purpose applications requiring standard ±1% tolerance and standard industrial temperature performance.

The ERA-8AEB9311V is appropriate for applications requiring tighter tolerance control (±0.1%), lower temperature coefficient drift (±25ppm/°C versus ±50ppm/°C), or automotive-grade reliability certification (AEC-Q200). Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Physical dimensions differ slightly: the ERA-8AEB9311V is 0.004" longer and 0.002" taller than the RT1206FRE079K31L. PCB layout verification is necessary to confirm clearance compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB9311V be used as a direct replacement for RT1206FRE079K31L?

A: Yes. Both components share identical resistance value (9.31 kOhms), power rating (0.25W), package format (1206), composition (thin film), operating temperature range (-55°C to 155°C), and termination count (2). The ERA-8AEB9311V offers improved tolerance and temperature coefficient specifications.

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

A: The RT1206FRE079K31L measures 0.122" L x 0.063" W x 0.026" H (3.10mm x 1.60mm x 0.65mm). The ERA-8AEB9311V measures 0.126" L x 0.063" W x 0.028" H (3.20mm x 1.60mm x 0.70mm). Length and height differences are minimal but should be verified against PCB layout constraints.

Q: Are both components RoHS compliant?

A: Yes. Both the RT1206FRE079K31L and ERA-8AEB9311V are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of the AEC-Q200 certification on the ERA-8AEB9311V?

A: AEC-Q200 is an automotive-grade reliability standard. The ERA-8AEB9311V meets this certification, making it suitable for automotive applications. The RT1206FRE079K31L does not carry this designation.

Q: Which component has better temperature stability?

A: The ERA-8AEB9311V has a temperature coefficient of ±25ppm/°C compared to ±50ppm/°C for the RT1206FRE079K31L, indicating superior temperature stability across the -55°C to 155°C operating range.
