RT1206FRE075K23L Equivalent & Substitute Parts

Part Overview

The RT1206FRE075K23L is a 5.23 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 precision resistive elements.

Substitute parts are identified to provide alternatives when the primary component is unavailable, when design requirements demand enhanced specifications, or when supply chain optimization is necessary. Equivalent parts maintain the same electrical performance characteristics within specified tolerances, while upgrade options may offer improved precision or automotive-grade reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE075K23L is determined by the following critical parameters:

• Resistance Value: Must be 5.23 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 construction ensures performance consistency
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Tolerance: ±1% or better (tighter tolerance acceptable)
• Regulatory Compliance: RoHS3 compliance required; REACH Unaffected status maintained

The ERA-8AEB5231V qualifies as a direct substitute and upgrade option, meeting all mandatory electrical and mechanical parameters while offering enhanced tolerance specification (±0.1% versus ±1%) and automotive-grade AEC-Q200 certification.

Engineering Selection Recommendations

RT1206FRE075K23L (Primary Component)

Select this part for standard applications where ±1% tolerance meets circuit requirements. YAGEO RT series components are actively produced with established supply availability. RoHS3 compliance and unlimited moisture sensitivity rating support general industrial and consumer electronics applications.

ERA-8AEB5231V (Substitute / Upgrade Option)

This Panasonic component serves as a direct substitute with enhanced specifications. The ±0.1% tolerance provides superior precision compared to the primary part's ±1% specification. AEC-Q200 automotive qualification indicates suitability for automotive and mission-critical applications. The lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) delivers improved thermal stability. Both components maintain identical power ratings, package dimensions within acceptable PCB assembly tolerances, and full regulatory compliance (RoHS3, REACH Unaffected).

Selection between these parts depends on application precision requirements and supply chain considerations rather than functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB5231V replace RT1206FRE075K23L in existing designs?

A: Yes. Both components share identical resistance value (5.23 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB5231V offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it functionally compatible and electrically superior for direct substitution.

Q: Are there physical footprint differences between these parts?

A: Dimensions are within acceptable assembly tolerances. RT1206FRE075K23L measures 3.10mm x 1.60mm with 0.65mm maximum seated height. ERA-8AEB5231V measures 3.20mm x 1.60mm with 0.70mm maximum seated height. Both conform to 1206 (3216 Metric) package specifications and use standard PCB footprints without requiring layout modifications.

Q: What is the significance of AEC-Q200 certification on the ERA-8AEB5231V?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the ERA-8AEB5231V meets automotive reliability and performance requirements. While not required for general-purpose applications, this qualification makes the part suitable for automotive, aerospace, and other mission-critical environments where enhanced reliability documentation is necessary.

Q: How do tolerance specifications affect circuit performance?

A: The RT1206FRE075K23L provides ±1% tolerance, while ERA-8AEB5231V provides ±0.1% tolerance. For precision analog circuits, filtering networks, or applications requiring tight resistor matching, the ERA-8AEB5231V's superior tolerance reduces component variation and improves circuit accuracy. For general-purpose applications, both tolerances are functionally equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RT1206FRE075K23L and ERA-8AEB5231V are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
