Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE075K9L is determined by the following critical parameters:

• Resistance value: 5.9 kOhms (exact match required)
• Package format: 1206 (3216 Metric) (physical and electrical compatibility)
• Power rating: 0.25W minimum (0.25W or higher acceptable)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider range acceptable)
• Composition: Thin film (maintains performance characteristics)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ERA-8AEB5901V qualifies as a substitute based on matching all critical parameters while offering improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE075K9L and ERA-8AEB5901V are active production components with ROHS3 compliance and MSL 1 rating. The ERA-8AEB5901V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The ERA-8AEB5901V offers tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) compared to the main part, making it suitable for precision circuit applications. Physical dimensions differ slightly; the ERA-8AEB5901V is marginally larger in length (3.20mm versus 3.10mm) and height (0.70mm versus 0.65mm), which must be verified against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB5901V replace RT1206FRE075K9L in any application?

A: Yes, provided PCB layout accommodates the slightly larger dimensions (3.20mm length and 0.70mm height versus 3.10mm and 0.65mm). Both components share identical resistance, power rating, operating temperature range, and package classification (1206 Metric).

Q: What is the significance of the tolerance difference (±1% versus ±0.1%)?

A: Tolerance defines the maximum deviation from the nominal 5.9 kOhms value. The ERA-8AEB5901V's ±0.1% tolerance provides tighter resistance accuracy, beneficial for precision analog circuits, filtering networks, and measurement applications. The RT1206FRE075K9L's ±1% tolerance is acceptable for general-purpose applications with less stringent accuracy requirements.

Q: Does the temperature coefficient difference affect substitution?

A: Temperature coefficient (±50ppm/°C versus ±25ppm/°C) describes resistance change over temperature. The ERA-8AEB5901V's lower coefficient indicates better stability across the -55°C to 155°C operating range. For applications with wide temperature variation or precision requirements, the ERA-8AEB5901V is preferable. For standard applications, both are functionally equivalent.

Q: Is AEC-Q200 qualification relevant for non-automotive applications?

A: AEC-Q200 certification indicates automotive-grade reliability and testing. While not required for non-automotive use, it demonstrates enhanced quality assurance. The ERA-8AEB5901V may be selected for mission-critical or high-reliability applications regardless of automotive context.

Q: Are there any PCB layout considerations?

A: Yes. The ERA-8AEB5901V is 0.10mm longer and 0.05mm taller than the RT1206FRE075K9L. Verify that PCB footprints and clearances accommodate these dimensions, particularly in space-constrained designs or high-density layouts.
