Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT1206FRE07845KL is determined by the following critical parameters:

• Resistance Value: Must be 845 kOhms
• Power Rating: Must be 0.25W minimum
• Package Type: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Composition: Thin film construction
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Tolerance: Substitute parts with equal or tighter tolerance (≤±1%) are acceptable

The ERA-8AEB8453V from Panasonic Electronic Components qualifies as a direct substitute. It maintains the same resistance, power rating, and package while offering improved tolerance (±0.1% vs ±1%) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB8453V represents an upgrade path from the RT1206FRE07845KL. Both parts are active products with full RoHS3 compliance and unlimited moisture sensitivity rating. The Panasonic substitute offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for applications requiring higher precision. The ERA-8AEB8453V carries AEC-Q200 automotive qualification, extending its applicability to automotive and high-reliability environments. Physical dimensions are comparable, with the Panasonic part measuring 3.20mm × 1.60mm versus 3.10mm × 1.60mm for the YAGEO part, maintaining 1206 package compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB8453V replace RT1206FRE07845KL in existing designs?

A: Yes. Both parts share identical resistance value (845 kOhms), power rating (0.25W), package footprint (1206), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB8453V offers superior tolerance and temperature stability.

Q: What are the physical dimension differences?

A: RT1206FRE07845KL measures 3.10mm × 1.60mm with 0.65mm maximum seated height. ERA-8AEB8453V measures 3.20mm × 1.60mm with 0.70mm maximum seated height. Both conform to 1206 package specifications and are PCB-compatible.

Q: Does the tighter tolerance of ERA-8AEB8453V affect circuit performance?

A: The ERA-8AEB8453V tolerance of ±0.1% is tighter than the RT1206FRE07845KL tolerance of ±1%. This provides improved accuracy in applications where resistance precision is critical. Circuits designed for ±1% tolerance will function correctly with ±0.1% components.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB8453V carries AEC-Q200 automotive qualification. The RT1206FRE07845KL does not specify automotive qualification. For automotive designs, ERA-8AEB8453V is the appropriate selection.

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

A: RT1206FRE07845KL has ±50ppm/°C temperature coefficient; ERA-8AEB8453V has ±25ppm/°C. Lower temperature coefficient indicates better resistance stability across the operating temperature range, beneficial for precision circuits operating across wide temperature variations.
