Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0734K8L is determined by the following critical parameters:

• Resistance Value: Must be 34.8 kOhms
• Package Type: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power Rating: Must be ≥0.25W (1/4W)
• Composition: Thin film technology ensures consistent performance characteristics
• Operating Temperature Range: Must cover or exceed -55°C to 155°C
• Compliance: RoHS3 and REACH compliance required for regulatory alignment

The ERA-8AEB3482V qualifies as a substitute based on matching all critical parameters while offering enhanced tolerance (±0.1% vs ±1%) and automotive-grade AEC-Q200 certification. The improved temperature coefficient (±25ppm/°C vs ±50ppm/°C) provides superior stability without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB3482V represents a direct substitute with enhanced specifications. Both components maintain identical resistance values, power ratings, package dimensions, and operating temperature ranges. The Panasonic ERA-8AEB3482V offers tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it suitable for applications requiring improved accuracy and thermal stability. Both parts maintain ROHS3 compliance and MSL 1 rating. The ERA-8AEB3482V carries AEC-Q200 automotive qualification, which may be advantageous for automotive or high-reliability applications but is not required for general industrial use. Selection between these parts should be based on application-specific tolerance requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3482V replace RT1206FRE0734K8L in existing designs? A: Yes. Both components share identical resistance values (34.8 kOhms), power ratings (0.25W), package types (1206), and operating temperature ranges (-55°C to 155°C). The ERA-8AEB3482V's improved tolerance and temperature coefficient do not create compatibility issues in standard applications.

Q: What are the physical dimension differences? A: The RT1206FRE0734K8L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. The ERA-8AEB3482V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit standard 1206 footprints; verify PCB layout clearances for tight spacing applications.

Q: Are both parts RoHS compliant? A: Yes. Both RT1206FRE0734K8L and ERA-8AEB3482V are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the significance of AEC-Q200 certification on the ERA-8AEB3482V? A: AEC-Q200 is an automotive qualification standard indicating the component meets automotive reliability and performance requirements. This certification is beneficial for automotive applications but not required for general industrial or consumer electronics use.

Q: Which part should be selected for high-precision applications? A: The ERA-8AEB3482V is preferred for applications requiring tighter tolerance control (±0.1% vs ±1%) and superior temperature stability (±25ppm/°C vs ±50ppm/°C).
