Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE073K57L is determined by the following criteria:

• Resistance Value: Must be 4.67 kOhms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or greater
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must encompass -55°C ~ 155°C minimum
• Compliance: ROHS3 compliance required for regulatory alignment

The ERA-8AEB3571V qualifies as a substitute based on matching resistance, package, power rating, and operating temperature specifications. Enhanced tolerance (±0.1% vs. ±1%) and automotive AEC-Q200 qualification represent performance upgrades rather than compatibility barriers.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE073K57L and ERA-8AEB3571V are active production components with ROHS3 compliance and identical operating temperature specifications. The ERA-8AEB3571V provides tighter tolerance (±0.1% vs. ±1%) and automotive AEC-Q200 qualification, making it suitable for applications requiring enhanced precision or automotive-grade reliability. Selection between these parts depends on application-specific tolerance requirements and supply availability rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3571V replace RT1206FRE073K57L in existing designs?

A: Yes. Both components share identical resistance value (4.67 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C ~ 155°C). PCB footprint and thermal characteristics remain compatible.

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

A: The ERA-8AEB3571V tolerance of ±0.1% provides tighter resistance accuracy compared to the RT1206FRE073K57L at ±1%. Applications requiring precise resistance values benefit from the substitute; general-purpose circuits typically function identically with either tolerance.

Q: Does AEC-Q200 qualification affect compatibility?

A: No. AEC-Q200 is an automotive reliability standard that qualifies the ERA-8AEB3571V for automotive applications. It does not restrict use in non-automotive circuits and represents a performance enhancement.

Q: Are the physical dimensions identical?

A: Both components use the 1206 (3216 Metric) package. Slight dimensional variations exist (RT1206FRE073K57L: 3.10mm L × 1.60mm W; ERA-8AEB3571V: 3.20mm L × 1.60mm W), but both fit standard 1206 PCB footprints without modification.

Q: What is the temperature coefficient difference?

A: The RT1206FRE073K57L has a temperature coefficient of ±50ppm/°C, while the ERA-8AEB3571V is ±25ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations, beneficial for precision applications.
