Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07432KL is determined by the following critical parameters:

• Resistance value must be 432 kOhms
• Package must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility
• Power rating must be 0.25W minimum
• Composition must be thin film to maintain performance characteristics
• Operating temperature range must encompass -55°C ~ 155°C
• RoHS3 compliance is required for regulatory alignment

The ERA-8AEB4323V qualifies as a direct substitute based on these criteria. While it offers improved tolerance (±0.1% versus ±1%) and automotive AEC-Q200 qualification, these represent enhancements rather than deviations from the core substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07432KL and ERA-8AEB4323V are active products with full RoHS3 compliance and identical moisture sensitivity ratings. The ERA-8AEB4323V provides enhanced performance through tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The ERA-8AEB4323V carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. Selection between these parts should be based on application requirements for tolerance precision and environmental qualification rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4323V replace RT1206FRE07432KL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package type, and operating temperature range. The ERA-8AEB4323V is mechanically and electrically compatible as a direct substitute.

Q: What are the dimensional differences between these parts?

A: The RT1206FRE07432KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB4323V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). Both fit the 1206 package specification and are compatible with standard PCB layouts.

Q: Does the improved tolerance of ERA-8AEB4323V affect circuit performance?

A: The ERA-8AEB4323V tolerance of ±0.1% is tighter than the RT1206FRE07432KL tolerance of ±1%. This provides improved resistance value accuracy. Applications requiring tighter tolerance control benefit from this specification; applications tolerant of ±1% variation function identically with either part.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB4323V carries AEC-Q200 automotive qualification. The RT1206FRE07432KL does not specify automotive qualification. For automotive applications, ERA-8AEB4323V is the appropriate selection.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-8AEB4323V temperature coefficient of ±25ppm/°C is lower than the RT1206FRE07432KL at ±50ppm/°C. Lower temperature coefficient indicates better resistance stability across the operating temperature range. Applications with stringent temperature stability requirements benefit from the ERA-8AEB4323V specification.
