Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206WRB072K8L are qualified based on the following critical parameters:

• Resistance value: 2.8 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thin film construction
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum coverage
• RoHS3 compliance and MSL Level 1 rating

The ERA-8ARW2801V from Panasonic Electronic Components meets all electrical and mechanical substitution criteria. This part maintains identical resistance, tolerance, power rating, and temperature characteristics while offering automotive-grade AEC-Q200 qualification as an additional feature.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206WRB072K8L and ERA-8ARW2801V are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The primary distinction is the AEC-Q200 automotive qualification of the Panasonic ERA-8ARW2801V, which provides additional reliability assurance for automotive and high-reliability applications. Selection between these parts should be based on application requirements: the YAGEO RT series for general industrial use, or the Panasonic ERA-8A series for automotive-grade applications requiring AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can ERA-8ARW2801V be used as a direct replacement for RT1206WRB072K8L?

A: Yes. Both parts share identical electrical specifications (2.8 kOhms, ±0.05% tolerance, ±10ppm/°C temperature coefficient, 0.25W power rating) and mechanical package format (1206/3216 Metric). The ERA-8ARW2801V includes additional AEC-Q200 automotive qualification.
