Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0729K4L is determined by the following critical parameters:

• Resistance Value: Must be 29.4 kOhms
• Package / Case: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power Rating: Must be ≥0.25W
• Composition: Thin film construction ensures performance characteristics
• Operating Temperature Range: Must cover or exceed -55°C ~ 155°C
• RoHS Compliance: ROHS3 Compliant status required for regulatory alignment

The ERA-8AEB2942V qualifies as a direct substitute because it maintains identical resistance value, package format, power rating, and operating temperature range while offering enhanced tolerance (±0.1% vs ±1%) and automotive-grade certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB2942V serves as a qualified substitute for the RT1206FRE0729K4L in applications where component availability or performance enhancement is required. Both parts maintain active production status and full ROHS3 compliance. The ERA-8AEB2942V provides tighter tolerance control (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for precision-critical circuits. The Panasonic component carries AEC-Q200 automotive qualification, extending its applicability to automotive and high-reliability environments. Mechanical compatibility is confirmed through identical 1206 package format and equivalent thermal characteristics across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2942V be used as a direct replacement for RT1206FRE0729K4L?

A: Yes. Both components share identical resistance value (29.4 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB2942V is mechanically and electrically compatible for direct substitution.

Q: What are the key differences between these two resistors?

A: The primary differences are tolerance specification (±0.1% vs ±1%), temperature coefficient (±25ppm/°C vs ±50ppm/°C), and automotive qualification (AEC-Q200 for ERA-8AEB2942V only). The Panasonic part offers superior stability and precision.

Q: Are there any package or footprint considerations?

A: Both components use the 1206 (3216 Metric) package. Physical dimensions are nearly identical: RT1206FRE0729K4L measures 3.10mm × 1.60mm, while ERA-8AEB2942V measures 3.20mm × 1.60mm. This minor length difference does not affect PCB layout compatibility.

Q: Do both parts meet RoHS requirements?

A: Yes. Both RT1206FRE0729K4L and ERA-8AEB2942V are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory standards.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For general-purpose applications, either part is acceptable. For precision circuits or automotive applications, the ERA-8AEB2942V is preferred due to tighter tolerance and AEC-Q200 certification.
