• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

The ERJ-U6QFR82V from Panasonic Electronic Components satisfies all electrical and mechanical equivalence criteria. Both components are thick film resistors with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both maintain 0805 package form factor with equivalent physical dimensions and termination count. Both achieve RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the RUT2012FR820CS and ERJ-U6QFR82V are Active products with full regulatory compliance.
