Substitute Part Grouping Explanation

Substitution of the RT1206FRE07340RL is determined by strict equivalence in the following critical parameters:

• Resistance Value: 340 Ohms (exact match required)
• Package Format: 1206 (3216 Metric) surface mount package
• Power Rating: 0.25W minimum
• Composition: Thin film construction
• Operating Temperature Range: -55°C to 155°C minimum coverage
• Termination Count: 2 terminations (standard for chip resistors)

The ERA-8AEB3400V qualifies as a direct substitute because it maintains identical resistance, package, power rating, and operating temperature specifications. Enhanced parameters such as improved tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C) represent performance upgrades rather than substitution barriers. The automotive AEC-Q200 qualification of the ERA-8AEB3400V provides additional reliability assurance for applications requiring automotive-grade components.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07340RL and ERA-8AEB3400V are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring regulatory compliance for current manufacturing standards. The RT1206FRE07340RL is suitable for general-purpose applications where standard tolerance and temperature coefficient specifications are acceptable. The ERA-8AEB3400V provides enhanced performance through tighter tolerance (±0.1%) and improved temperature stability (±25ppm/°C), with the additional benefit of AEC-Q200 automotive qualification. Selection between these components should be based on application-specific requirements for tolerance precision, temperature stability, and automotive-grade reliability assurance. Both components are electrically and mechanically compatible within the 1206 package format and support identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB3400V directly replace the RT1206FRE07340RL in existing designs?

A: Yes. Both components share identical resistance values (340 Ohms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB3400V features improved tolerance and temperature coefficient specifications, which represent performance enhancements rather than compatibility issues.

Q: What is the significance of the ±0.1% tolerance in the ERA-8AEB3400V compared to the ±1% tolerance in the RT1206FRE07340RL?

A: The ERA-8AEB3400V provides tighter tolerance control, resulting in more precise resistance values across production batches. This is beneficial for precision analog circuits, measurement instrumentation, and applications requiring strict component value matching. Standard tolerance applications can use either component without functional impact.

Q: Does the AEC-Q200 qualification of the ERA-8AEB3400V affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates enhanced reliability testing and quality assurance standards. Components meeting automotive standards are fully compatible with industrial and commercial applications and do not introduce compatibility restrictions.

Q: Are the physical dimensions of both components identical?

A: Both components use the 1206 (3216 Metric) package format. Minor dimensional variations exist: RT1206FRE07340RL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" maximum seated height, while ERA-8AEB3400V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" maximum seated height. These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What is the temperature coefficient difference, and when does it matter?

A: The RT1206FRE07340RL has a temperature coefficient of ±50ppm/°C, while the ERA-8AEB3400V has ±25ppm/°C. This difference becomes significant in precision circuits operating across wide temperature ranges or in applications requiring stable resistance values over temperature variations. Standard applications are unaffected by this parameter difference.
