RT1206FRE07523KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07523KL is a 523 kOhms ±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 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, enhanced performance specifications, or when primary component availability is constrained. Substitute components must maintain electrical equivalence in resistance value, power rating, and package dimensions while meeting or exceeding the original specifications.

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE07523KL are qualified based on the following criteria:

Electrical Equivalence: Resistance value must be 523 kOhms. Tolerance may be equal to or tighter than ±1%. Power rating must be equal to or greater than 0.25W.

Package Compatibility: Package designation must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Environmental Specifications: Operating temperature range must encompass or exceed -55°C to 155°C. Temperature coefficient should be equal to or lower in absolute value to maintain circuit stability.

Compliance Requirements: RoHS3 compliance and MSL 1 rating are mandatory for supply chain and manufacturing process compatibility.

Composition: Thin film construction is required to maintain performance characteristics and frequency response behavior equivalent to the original component.

The ERA-8AEB5233V qualifies as a direct substitute based on these criteria, offering improved tolerance specification (±0.1% versus ±1%) and automotive-grade qualification (AEC-Q200) while maintaining all other electrical and mechanical parameters within acceptable limits.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB5233V represents a performance upgrade path for applications where tighter tolerance control is required. The ±0.1% tolerance specification provides improved accuracy compared to the ±1% tolerance of the RT1206FRE07523KL, making it suitable for precision analog circuits, reference networks, and measurement applications.

The lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) of the ERA-8AEB5233V results in superior temperature stability, beneficial for circuits operating across extended temperature ranges or requiring minimal drift characteristics.

Both components maintain identical package dimensions, power ratings, and compliance certifications. The ERA-8AEB5233V carries AEC-Q200 automotive qualification, which indicates suitability for automotive and high-reliability applications. This qualification does not restrict use in non-automotive applications.

Selection between these components should be based on circuit performance requirements and application environment rather than availability alone. The RT1206FRE07523KL remains appropriate for general-purpose applications where ±1% tolerance is acceptable. The ERA-8AEB5233V is preferred for precision applications and automotive implementations.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB5233V be used as a direct replacement for RT1206FRE07523KL in existing designs?

A: Yes. Both components share identical resistance values, power ratings, package dimensions, and operating temperature ranges. The ERA-8AEB5233V features tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it electrically compatible and functionally superior. No PCB layout modifications are required.

Q: What is the significance of the ±0.1% tolerance specification on the ERA-8AEB5233V?

A: The ±0.1% tolerance indicates a tighter manufacturing specification compared to the ±1% tolerance of the RT1206FRE07523KL. This means the actual resistance value will remain closer to the nominal 523 kOhms specification across the production batch, reducing circuit performance variation and improving overall system accuracy.

Q: Does the AEC-Q200 qualification on the ERA-8AEB5233V restrict its use to automotive applications?

A: No. AEC-Q200 qualification indicates the component meets automotive industry reliability and testing standards. This qualification is not restrictive; the component is suitable for any application, including consumer, industrial, and military environments.

Q: Are the physical dimensions of both components identical?

A: The components are functionally equivalent in package designation (1206 / 3216 Metric) but have minor dimensional variations. RT1206FRE07523KL dimensions are 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. ERA-8AEB5233V dimensions are 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. These variations remain within standard 1206 package tolerances and do not affect PCB compatibility.

Q: What is the temperature coefficient and why does it matter?

A: Temperature coefficient measures how much the resistance value changes per degree Celsius. The RT1206FRE07523KL has ±50ppm/°C while the ERA-8AEB5233V has ±25ppm/°C. Lower temperature coefficient means better stability across temperature variations, which is critical for precision circuits, sensor interfaces, and applications operating in wide temperature environments.

Q: Are both components RoHS3 compliant?

A: Yes. Both RT1206FRE07523KL and ERA-8AEB5233V are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), meeting current environmental and supply chain requirements.
