RT1206FRE07143KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07143KL is a 143 kOhms ±1% 0.25W thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This component is actively produced and widely used in general-purpose electronic applications requiring standard tolerance resistive elements. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07143KL is determined by the following critical parameters:

• Resistance Value: Must be 143 kOhms
• Package Type: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.25W minimum
• Composition: Thin film construction
• Operating Temperature Range: Must encompass -55°C ~ 155°C
• RoHS Compliance: ROHS3 Compliant

The ERA-8AEB1433V qualifies as a substitute because it maintains identical resistance value, package type, power rating, composition, operating temperature range, and RoHS compliance status. Enhanced specifications (±0.1% tolerance and ±25ppm/°C temperature coefficient) represent improvements over the original part and do not restrict substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07143KL and ERA-8AEB1433V are active production components with ROHS3 compliance and identical moisture sensitivity ratings. The ERA-8AEB1433V provides tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring enhanced precision. The ERA-8AEB1433V carries AEC-Q200 automotive qualification, which may be relevant for automotive or high-reliability applications. Selection between these parts should be based on application tolerance requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1433V replace RT1206FRE07143KL in all applications?

A: Yes, from an electrical and mechanical standpoint. The ERA-8AEB1433V maintains identical resistance value, power rating, package type, and operating temperature range. The improved tolerance and temperature coefficient represent enhanced performance characteristics that do not restrict compatibility.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The RT1206FRE07143KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. The ERA-8AEB1433V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. These differences are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of the AEC-Q200 rating on the ERA-8AEB1433V?

A: AEC-Q200 is an automotive qualification standard. This rating indicates the ERA-8AEB1433V has undergone additional reliability testing for automotive applications. This qualification is beneficial for automotive designs but does not restrict use in non-automotive applications.

Q: Are both parts available in the same packaging format?

A: The RT1206FRE07143KL is supplied in Tape & Reel (TR) format. The ERA-8AEB1433V is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are standard for SMD component distribution and do not affect component functionality.

Q: Which part should be selected for high-precision applications?

A: The ERA-8AEB1433V is the appropriate choice for applications requiring tighter tolerance control, as it provides ±0.1% tolerance compared to ±1% for the RT1206FRE07143KL.
