Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0720K5L is determined by the following critical parameters:

• Resistance Value: Must be 20.5 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 technology maintains performance characteristics
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Compliance: ROHS3 compliance required for regulatory alignment

The ERA-8AEB2052V qualifies as a direct substitute based on matching all critical parameters while offering enhanced tolerance specification (±0.1% versus ±1%) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB2052V (Panasonic) serves as a qualified substitute for the RT1206FRE0720K5L. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility.

The Panasonic ERA-8AEB2052V offers tighter tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), providing enhanced precision characteristics. The AEC-Q200 automotive qualification of the ERA-8AEB2052V indicates suitability for automotive-grade applications where the YAGEO RT series may not be specified.

Selection between these components should be based on application requirements for tolerance precision, temperature stability, and automotive qualification necessity. Both components are actively produced and available in volume quantities.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB2052V replace the RT1206FRE0720K5L in existing designs?

A: Yes. Both components share identical resistance value (20.5 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB2052V provides enhanced tolerance and temperature coefficient performance.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE0720K5L measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB2052V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.028" (0.70mm). Both fit the 1206 package footprint with minor dimensional variation within standard tolerance.

Q: Are both components RoHS compliant?

A: Yes. Both the RT1206FRE0720K5L and ERA-8AEB2052V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the AEC-Q200 rating on the Panasonic part?

A: AEC-Q200 is an automotive electronics qualification standard. The ERA-8AEB2052V meets automotive-grade reliability requirements, making it suitable for automotive applications where component qualification is specified.

Q: Which part should be selected for precision-critical applications?

A: The ERA-8AEB2052V offers superior precision with ±0.1% tolerance and ±25ppm/°C temperature coefficient compared to the RT1206FRE0720K5L (±1% tolerance, ±50ppm/°C). Selection depends on circuit requirements for resistance accuracy and thermal stability.
