Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT1206FRE072K94L is determined by the following critical parameters:

• Resistance Value: Must be 2.94 kOhms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film construction maintains electrical performance characteristics
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

The ERA-8AEB2941V from Panasonic Electronic Components qualifies as a direct substitute. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations. The substitute maintains identical resistance value, package format, power rating, and operating temperature range, ensuring full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE072K94L and ERA-8AEB2941V are active production components with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts should be based on application requirements:

The RT1206FRE072K94L is suitable for general-purpose applications where standard ±1% tolerance and ±50ppm/°C temperature coefficient meet design specifications.

The ERA-8AEB2941V is appropriate for applications requiring tighter tolerance control (±0.1%), improved temperature stability (±25ppm/°C), or automotive-grade reliability (AEC-Q200 certification). The AEC-Q200 qualification indicates suitability for automotive and high-reliability environments.

Both components are mechanically and electrically interchangeable within the specified parameter ranges. Physical dimensions differ slightly (YAGEO: 3.10mm L × 1.60mm W; Panasonic: 3.20mm L × 1.60mm W), but both conform to the 1206 package standard and will fit standard PCB footprints designed for this package format.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2941V replace RT1206FRE072K94L in existing designs?

A: Yes. Both components share identical resistance value (2.94 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB2941V offers superior tolerance and temperature coefficient, making it a direct substitute with performance enhancement.

Q: What is the significance of the ±0.1% tolerance in the Panasonic part?

A: The ERA-8AEB2941V tolerance of ±0.1% is tighter than the RT1206FRE072K94L tolerance of ±1%. This means the actual resistance value will be closer to the nominal 2.94 kOhms specification, reducing circuit performance variation. This is beneficial in precision analog circuits, measurement equipment, and applications sensitive to component value drift.

Q: Does the AEC-Q200 rating on the Panasonic part affect general-purpose applications?

A: No. AEC-Q200 is an automotive qualification standard indicating enhanced reliability testing and quality assurance. Components with this rating are suitable for automotive use but are equally reliable in general-purpose applications. The qualification represents an additional quality assurance level, not a limitation.

Q: Are there physical compatibility concerns between these two 1206 packages?

A: Both components conform to the 1206 (3216 Metric) package standard. Minor dimensional variations (YAGEO: 3.10mm × 1.60mm; Panasonic: 3.20mm × 1.60mm) are within standard package tolerances and will not affect PCB footprint compatibility or assembly processes.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating require no special moisture control during storage, handling, or assembly. Both the RT1206FRE072K94L and ERA-8AEB2941V can be stored and processed under standard conditions without moisture-related degradation.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the RT1206FRE072K94L and ERA-8AEB2941V are ROHS3 compliant, meeting European Union restrictions on hazardous substances. Both are suitable for applications requiring regulatory compliance with environmental and safety standards.
