Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0731K6L is determined by the following critical parameters:

• Resistance value: 31.6 kOhms (exact match required)
• Package type: 1206 (3216 Metric) form factor
• Power rating: 0.25W minimum
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance and MSL Level 1 rating

The ERA-8AEB3162V qualifies as a direct substitute by meeting all mandatory parameters while offering enhanced tolerance specification (±0.1% versus ±1%) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE0731K6L and ERA-8AEB3162V are active production components with full RoHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and assembly processes.

The ERA-8AEB3162V provides enhanced performance through tighter tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring higher precision. The AEC-Q200 automotive qualification of the ERA-8AEB3162V extends its applicability to automotive and mission-critical environments.

Selection between these parts should be based on application-specific tolerance requirements and environmental qualification needs rather than functional compatibility, as both components satisfy the core electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3162V be used as a direct replacement for RT1206FRE0731K6L?

A: Yes. Both components share identical resistance value (31.6 kOhms), package form factor (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB3162V meets or exceeds all mandatory electrical and mechanical parameters.

Q: What are the key differences between these parts?

A: The ERA-8AEB3162V offers tighter tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and automotive AEC-Q200 qualification. Physical dimensions vary slightly (3.20mm × 1.60mm versus 3.10mm × 1.60mm length and 0.70mm versus 0.65mm height).

Q: Are there any package compatibility concerns?

A: Both components use the 1206 (3216 Metric) package. Minor dimensional variations (length and height) fall within standard PCB pad tolerance specifications and do not affect assembly compatibility.

Q: Do both parts meet environmental and compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (unlimited moisture sensitivity protection). Both are active production parts with established supply chains.

Q: Which part should be selected for precision-critical applications?

A: The ERA-8AEB3162V is the appropriate choice for applications requiring tolerance better than ±1% or lower temperature coefficient performance. The RT1206FRE0731K6L is suitable for general-purpose applications where ±1% tolerance is acceptable.
