RT1206FRE07357KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07357KL is a 357 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or meet specific application requirements such as enhanced tolerance specifications or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07357KL is determined by the following critical parameters:

• Resistance Value: Must be 357 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.25W (1/4W) minimum
• Composition: Thin film construction
• Operating Temperature Range: Must cover -55°C to 155°C
• Compliance: ROHS3 compliance required

The ERA-8AEB3573V from Panasonic Electronic Components qualifies as a direct substitute. While it offers enhanced tolerance (±0.1% versus ±1%) and automotive AEC-Q200 certification, it maintains identical resistance value, package format, power rating, and operating temperature specifications. The improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) and tighter tolerance represent performance upgrades rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3573V represents a direct functional substitute for the RT1206FRE07357KL with performance enhancements. Both parts maintain active production status and full ROHS3 compliance.

Selection between these parts should be based on application-specific requirements:

• RT1206FRE07357KL: Suitable for general-purpose applications where ±1% tolerance and standard thin film performance meet circuit requirements.
• ERA-8AEB3573V: Appropriate for applications requiring tighter tolerance control (±0.1%), lower temperature coefficient drift (±25ppm/°C), or automotive-grade reliability (AEC-Q200 certification).

Both parts are physically compatible within the 1206 package footprint and operate identically across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3573V replace RT1206FRE07357KL in existing designs?

A: Yes. Both parts share identical resistance value (357 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB3573V offers improved tolerance and temperature coefficient specifications, making it a direct upgrade.

Q: What is the physical difference between these parts?

A: Dimensional differences are minimal. RT1206FRE07357KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. ERA-8AEB3573V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit standard 1206 footprints without layout modifications.

Q: Does the tighter tolerance of ERA-8AEB3573V affect circuit compatibility?

A: No. Tighter tolerance (±0.1% versus ±1%) represents improved performance. Circuits designed for ±1% tolerance will function correctly with ±0.1% components.

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

A: Yes. Both are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the significance of AEC-Q200 certification on the ERA-8AEB3573V?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. This certification is relevant only for applications requiring automotive-grade components. Standard applications do not require this certification.
