RT1206FRE07383RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07383RL is a 383 Ohms ±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 and operates across the 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). Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific performance requirements such as improved tolerance or automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07383RL is determined by the following critical parameters:

• Resistance value must be 383 Ohms
• Package format 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 to 155°C
• RoHS3 compliance is required

The ERA-8AEB3830V qualifies as a direct substitute based on these parameters. While it offers improved tolerance (±0.1% versus ±1%) and automotive AEC-Q200 qualification, these represent enhancements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3830V serves as a direct substitute for the RT1206FRE07383RL in applications where the core electrical specifications are met. Both parts maintain identical resistance values, power ratings, package formats, and operating temperature ranges. The ERA-8AEB3830V provides superior tolerance performance (±0.1% versus ±1%) and includes AEC-Q200 automotive qualification, making it suitable for applications requiring enhanced precision or automotive-grade reliability. Selection between these parts should be based on application requirements, inventory availability, and cost considerations rather than electrical compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB3830V replace the RT1206FRE07383RL in any circuit?

A: Yes, the ERA-8AEB3830V is electrically and mechanically compatible with the RT1206FRE07383RL. Both parts share identical resistance values, power ratings, package formats, and operating temperature ranges. The substitute offers improved tolerance and automotive qualification as additional benefits.

Q: What is the significance of the ±0.1% tolerance in the ERA-8AEB3830V compared to the ±1% tolerance in the RT1206FRE07383RL?

A: The ERA-8AEB3830V maintains tighter tolerance specifications, meaning its actual resistance value will remain closer to the nominal 383 Ohms value across production batches. This is beneficial in precision analog circuits, measurement equipment, and applications where component value drift must be minimized.

Q: Are there physical differences between these two 1206 package resistors?

A: Both parts use the 1206 (3216 Metric) package format. Minor dimensional variations exist: the RT1206FRE07383RL measures 0.122" L x 0.063" W with a maximum seated height of 0.026", while the ERA-8AEB3830V measures 0.126" L x 0.063" W with a maximum seated height of 0.028". These differences are within standard PCB design tolerances and do not affect interchangeability.

Q: What does AEC-Q200 qualification mean for the ERA-8AEB3830V?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component for use in automotive applications. It indicates the part has undergone rigorous testing for reliability, temperature cycling, and performance stability under automotive operating conditions.

Q: Are both parts RoHS3 compliant?

A: Yes, both the RT1206FRE07383RL and ERA-8AEB3830V are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), making them suitable for standard PCB assembly and storage conditions.
