RT1206FRE07158KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07158KL is a 158 kOhms ±1% thin film chip resistor manufactured by YAGEO in 1206 (3216 Metric) package format with 0.25W power rating. This component is actively produced and widely used in general-purpose electronic applications requiring precision resistive elements. Substitute parts are identified to provide design flexibility, inventory alternatives, or enhanced performance specifications while maintaining functional compatibility within the same package and resistance value parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07158KL is determined by the following critical parameters:

• Resistance value must be 158 kOhms
• Package / Case must be 1206 (3216 Metric)
• Power rating must be 0.25W (1/4W) or greater
• Composition must be thin film
• Operating temperature range must encompass -55°C ~ 155°C
• RoHS3 compliance required

The ERA-8AEB1583V qualifies as a direct substitute based on these parameters. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations from the substitution criteria. Both components share identical resistance value, package format, power rating, and temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07158KL and ERA-8AEB1583V are active products with full RoHS3 compliance and MSL Level 1 rating. The ERA-8AEB1583V includes AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability standards. Selection between these components should be based on application-specific requirements: the RT1206FRE07158KL for general-purpose applications, and the ERA-8AEB1583V for automotive or high-reliability environments where tighter tolerance and lower temperature coefficient provide performance advantages.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1583V replace RT1206FRE07158KL in any circuit?

A: Yes, within the constraints of the specified parameters. Both components share identical resistance value (158 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB1583V offers superior tolerance and temperature stability, making it suitable for applications where the original part is specified.

Q: What is the physical difference between these components?

A: Dimensional differences are minimal. RT1206FRE07158KL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). ERA-8AEB1583V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.028" (0.70mm). Both fit the 1206 package specification and are compatible with standard PCB layouts designed for this package format.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. The ERA-8AEB1583V carries AEC-Q200 automotive qualification, which the RT1206FRE07158KL does not specify. This distinction is relevant only for applications requiring automotive-grade component certification.

Q: Which component should be selected for temperature-sensitive applications?

A: The ERA-8AEB1583V is preferable for temperature-sensitive applications due to its lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). This characteristic reduces resistance drift across the operating temperature range, providing improved circuit stability.
