RT1206FRE07348RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07348RL is a 348 Ohm ±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 with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained across the same resistance value, tolerance grade, power rating, and package specification, while potentially offering enhanced performance characteristics or alternative supplier availability.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07348RL is determined by the following critical parameters:

• Resistance value must equal 348 Ohms
• Package must be 1206 (3216 Metric) with identical footprint dimensions
• Power rating must be minimum 0.25W (1/4W)
• Composition must be thin film technology
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance required
• Tolerance may be equal to or tighter than ±1%

The ERA-8AEB3480V meets all substitution criteria with identical electrical specifications and enhanced tolerance performance.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3480V qualifies as a direct substitute for the RT1206FRE07348RL based on matching core electrical and mechanical specifications. Both components are Active products with ROHS3 compliance and identical package footprints.

The ERA-8AEB3480V offers enhanced performance through tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The substitute incorporates Automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Selection between these parts depends on application requirements for tolerance precision and temperature stability. Both maintain identical footprint compatibility and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3480V replace RT1206FRE07348RL in existing designs?

A: Yes. Both components share identical resistance value (348 Ohms), power rating (0.25W), package format (1206), and operating temperature range (-55°C to 155°C). The substitute features tighter tolerance and lower temperature coefficient, making it functionally compatible for direct substitution.

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

A: The RT1206FRE07348RL has ±1% tolerance, while the ERA-8AEB3480V has ±0.1% tolerance. The substitute provides four times tighter tolerance specification, beneficial for precision circuit applications.

Q: Are the physical dimensions identical?

A: Both components use the 1206 (3216 Metric) package. The RT1206FRE07348RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. The ERA-8AEB3480V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. The ERA-8AEB3480V meets this specification, indicating enhanced reliability testing and performance validation for automotive applications. This certification is not required for general industrial use but provides additional assurance for mission-critical applications.

Q: Are both parts RoHS compliant?

A: Yes. Both RT1206FRE07348RL and ERA-8AEB3480V are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
