RT1206FRE071K58L Equivalent & Substitute Parts

Part Overview

The RT1206FRE071K58L is a 1.58 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and widely used in general-purpose electronic applications requiring standard tolerance resistive elements.

Substitute parts are identified to provide alternatives when the primary component is unavailable, when design requirements demand enhanced performance characteristics, or when supply chain optimization is necessary. Substitutes maintain electrical and mechanical compatibility while potentially offering improved specifications such as tighter tolerance or enhanced reliability ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE071K58L is determined by the following critical parameters:

• Resistance Value: Must be 1.58 kOhms (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film technology ensures consistent performance characteristics
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Packaging Format: Tape & Reel (TR) for automated assembly compatibility

The identified substitute ERA-8AEB1581V meets all mandatory substitution criteria. This part maintains identical resistance, package, power rating, and operating temperature specifications while offering enhanced tolerance (±0.1% versus ±1%) and automotive-grade reliability certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE071K58L and ERA-8AEB1581V are active production components with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making them suitable for standard manufacturing and storage conditions.

The ERA-8AEB1581V substitute offers improved performance specifications: tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The substitute carries AEC-Q200 automotive qualification, indicating enhanced reliability testing and suitability for demanding applications.

Selection between the main part and substitute should be based on application requirements. The RT1206FRE071K58L is appropriate for general-purpose applications where standard tolerance is acceptable. The ERA-8AEB1581V is suitable when precision tolerance, lower temperature drift, or automotive-grade reliability is required.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1581V be used as a direct replacement for RT1206FRE071K58L?

A: Yes. Both components share identical resistance value (1.58 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C ~ 155°C). The substitute is mechanically and electrically compatible for PCB assembly and circuit operation.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification (±0.1% versus ±1%), temperature coefficient (±25ppm/°C versus ±50ppm/°C), and reliability certification. The ERA-8AEB1581V includes AEC-Q200 automotive qualification, indicating enhanced reliability testing protocols.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RT1206FRE071K58L and ERA-8AEB1581V are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly equipment.

Q: Do these parts have the same physical dimensions?

A: Both components use the 1206 (3216 Metric) package. Slight dimensional variations exist: RT1206FRE071K58L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" max height, while ERA-8AEB1581V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" max height. These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Which part should be selected for precision applications?

A: The ERA-8AEB1581V is recommended for applications requiring tighter tolerance control and lower temperature drift. Its ±0.1% tolerance and ±25ppm/°C temperature coefficient provide superior stability compared to the ±1% tolerance and ±50ppm/°C coefficient of the RT1206FRE071K58L.

Q: Are both parts RoHS compliant?

A: Yes. Both RT1206FRE071K58L and ERA-8AEB1581V are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and distribution.
