Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07191RL is determined by the following critical parameters:

• Resistance Value: Must be 191 Ohms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film construction maintains electrical performance characteristics
• Operating Temperature Range: Must encompass or match -55°C to 155°C
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Moisture Sensitivity: MSL Level 1 or equivalent

The ERA-8AEB1910V from Panasonic Electronic Components qualifies as a direct substitute. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations from the core electrical and mechanical requirements. Both components share identical resistance value, package format, power rating, operating temperature range, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB1910V serves as a qualified substitute for the RT1206FRE07191RL in applications where component availability or performance enhancement is required. The Panasonic part maintains full electrical and mechanical compatibility while providing tighter tolerance control and improved temperature stability through its lower temperature coefficient specification. The AEC-Q200 automotive qualification of the ERA-8AEB1910V indicates enhanced reliability testing and quality assurance protocols, making it suitable for both automotive and industrial applications. Both components carry identical RoHS3 compliance and MSL Level 1 ratings, ensuring regulatory and environmental compatibility across supply chain transitions.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB1910V replace the RT1206FRE07191RL in existing designs?

A: Yes. Both components share identical resistance value (191 Ohms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB1910V offers improved tolerance and temperature coefficient specifications, which represent performance enhancements rather than compatibility issues.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE07191RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with a maximum seated height of 0.026" (0.65mm). The ERA-8AEB1910V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with a maximum seated height of 0.028" (0.70mm). Both fit the standard 1206 package footprint with negligible dimensional variance.

Q: Are there tolerance or accuracy considerations when substituting?

A: The ERA-8AEB1910V provides ±0.1% tolerance compared to the RT1206FRE07191RL's ±1% tolerance. This represents improved accuracy and is suitable for applications requiring tighter resistance specifications. No design modifications are necessary for this upgrade.

Q: What is the significance of the AEC-Q200 rating on the Panasonic part?

A: AEC-Q200 certification indicates the component has undergone automotive-grade reliability testing and qualification. This certification is applicable to both automotive and industrial applications requiring enhanced quality assurance documentation.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both the RT1206FRE07191RL and ERA-8AEB1910V carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating no moisture-related storage or handling restrictions.
