Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE073K09L is determined by the following critical parameters:

• Resistance Value: Must be 3.09 kOhms
• Package Type: Must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with PCB layouts
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film construction ensures performance characteristics suitable for precision applications
• Operating Temperature Range: Must encompass -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The ERA-8AEB3091V from Panasonic Electronic Components qualifies as a substitute part. It maintains the same resistance value, package type, power rating, and operating temperature range. The substitute offers enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE073K09L and ERA-8AEB3091V are active products with full ROHS3 compliance and MSL 1 moisture sensitivity ratings, ensuring regulatory and environmental compliance across standard manufacturing processes.

The RT1206FRE073K09L is suitable for general-purpose applications where standard tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications are acceptable.

The ERA-8AEB3091V is recommended for applications requiring enhanced precision and stability. Its ±0.1% tolerance and ±25ppm/°C temperature coefficient provide superior performance margins. The AEC-Q200 automotive qualification indicates suitability for automotive and high-reliability environments where component stability and failure rate management are critical.

Selection between these parts should be based on application-specific tolerance requirements, thermal stability demands, and supply chain availability rather than functional interchangeability alone.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3091V directly replace RT1206FRE073K09L in existing designs?

A: Yes, from a mechanical and electrical standpoint. Both components share identical resistance values, package types (1206), power ratings (0.25W), and operating temperature ranges (-55°C to 155°C). Physical dimensions are comparable (RT1206FRE073K09L: 3.10mm × 1.60mm; ERA-8AEB3091V: 3.20mm × 1.60mm), with negligible height differences (0.65mm versus 0.70mm maximum seated height). PCB layout compatibility is maintained.

Q: What are the tolerance differences between these parts?

A: The RT1206FRE073K09L offers ±1% tolerance, while the ERA-8AEB3091V provides ±0.1% tolerance. The substitute part delivers tighter tolerance specifications, reducing resistance value variation across the production batch and improving circuit performance predictability.

Q: How do temperature coefficients affect part selection?

A: The RT1206FRE073K09L has a temperature coefficient of ±50ppm/°C, while the ERA-8AEB3091V is ±25ppm/°C. Lower temperature coefficients indicate better resistance stability across temperature variations. Applications operating across wide temperature ranges or requiring stable circuit performance benefit from the ERA-8AEB3091V's superior temperature stability.

Q: Are both parts RoHS compliant?

A: Yes, both the RT1206FRE073K09L and ERA-8AEB3091V are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting standard environmental and regulatory requirements for commercial and industrial applications.

Q: What is the significance of AEC-Q200 qualification on the ERA-8AEB3091V?

A: AEC-Q200 is an automotive industry standard qualification indicating the component meets stringent reliability, quality, and performance requirements for automotive applications. While the RT1206FRE073K09L does not specify this rating, the ERA-8AEB3091V's AEC-Q200 qualification makes it suitable for automotive and high-reliability environments where component failure rate management and long-term stability are critical.
