Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0741K2L are qualified based on the following criteria:

• Identical resistance value: 41.2 kOhms
• Identical package format: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Compatible operating temperature range: -55°C to 155°C minimum
• Equivalent or superior tolerance specification
• ROHS3 compliance maintained
• MSL 1 rating maintained

The ERA-8AEB4122V from Panasonic Electronic Components qualifies as a direct substitute. This part meets all mandatory electrical and mechanical parameters while offering improved tolerance (±0.1% versus ±1%) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE0741K2L and ERA-8AEB4122V maintain Active product status with full ROHS3 compliance and MSL 1 rating. The ERA-8AEB4122V provides enhanced tolerance specification (±0.1% versus ±1%) and automotive-grade AEC-Q200 qualification, making it suitable for applications requiring tighter resistance accuracy or automotive-qualified components. Physical dimensions show minor variation within the 1206 package specification, with the Panasonic part measuring 0.126" L versus 0.122" L and 0.028" height versus 0.026" height. Both parts operate across the identical -55°C to 155°C temperature range. Selection between these parts depends on application-specific tolerance requirements and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4122V replace RT1206FRE0741K2L in existing designs?

A: Yes. Both parts share identical resistance value (41.2 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C to 155°C). The ERA-8AEB4122V offers superior tolerance (±0.1%) and maintains equivalent compliance certifications.

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

A: The RT1206FRE0741K2L measures 0.122" L x 0.063" W with 0.026" maximum seated height. The ERA-8AEB4122V measures 0.126" L x 0.063" W with 0.028" maximum seated height. Both conform to 1206 (3216 Metric) package specifications. Verify PCB layout clearances if space constraints exist.

Q: Does tolerance difference affect circuit performance?

A: Tolerance difference depends on application requirements. The RT1206FRE0741K2L provides ±1% tolerance; the ERA-8AEB4122V provides ±0.1% tolerance. Applications requiring tighter resistance accuracy benefit from the Panasonic part. Standard applications typically accept either specification.

Q: Are both parts suitable for automotive applications?

A: The RT1206FRE0741K2L is standard industrial grade. The ERA-8AEB4122V carries AEC-Q200 automotive qualification. Select ERA-8AEB4122V for automotive-qualified designs.

Q: What is the temperature coefficient difference?

A: The RT1206FRE0741K2L has ±50ppm/°C temperature coefficient. The ERA-8AEB4122V has ±25ppm/°C temperature coefficient. Lower temperature coefficient indicates better resistance stability across temperature variations.
