RT1206FRE071K91L Equivalent & Substitute Parts

Part Overview

The RT1206FRE071K91L is a 1.91 kOhms ±1% thin film chip resistor manufactured by YAGEO in 1206 (3216 Metric) package format. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 155°C. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). As an active product with 1072 units in stock, this resistor serves general-purpose applications requiring standard tolerance specifications.

Substitute parts are identified when equivalent electrical performance can be maintained while offering enhanced specifications, improved availability, or specialized certifications for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE071K91L is determined by the following critical parameters:

• Resistance Value: Must be 1.91 kOhms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be ≥0.25W to support circuit requirements
• Composition: Thin film technology maintains performance characteristics
• Operating Temperature Range: Must encompass -55°C to 155°C minimum
• Compliance: ROHS3 and REACH compliance required for regulatory alignment

The ERA-8AEB1911V qualifies as a substitute part because it maintains the same resistance value, package format, power rating, and operating temperature range while offering enhanced tolerance (±0.1% versus ±1%) and automotive-grade AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

The RT1206FRE071K91L and ERA-8AEB1911V are electrically and mechanically interchangeable for 1206 package applications requiring 1.91 kOhms resistance at 0.25W power dissipation.

Selection between these parts depends on application-specific requirements:

• RT1206FRE071K91L is suitable for general-purpose applications where standard ±1% tolerance meets circuit specifications and standard compliance is sufficient.

• ERA-8AEB1911V is appropriate for applications requiring tighter tolerance control (±0.1%), lower temperature coefficient drift (±25ppm/°C versus ±50ppm/°C), or automotive-grade reliability through AEC-Q200 certification. This part is recommended for precision analog circuits, automotive systems, or applications with stringent performance requirements.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1911V replace RT1206FRE071K91L in any circuit?

A: Yes, from an electrical and mechanical standpoint. The ERA-8AEB1911V maintains identical resistance value, power rating, and package format. The enhanced tolerance (±0.1% versus ±1%) and lower temperature coefficient represent performance improvements that do not create compatibility issues in circuits designed for the original part.

Q: What is the significance of the ±0.1% tolerance in ERA-8AEB1911V?

A: Tighter tolerance means the actual resistance value will remain closer to the nominal 1.91 kOhms across the operating temperature range. This is beneficial in precision measurement circuits, analog signal conditioning, and applications where resistor value drift directly impacts circuit performance.

Q: Does the AEC-Q200 certification on ERA-8AEB1911V affect general-purpose applications?

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing and quality assurance. This certification does not restrict use in non-automotive applications; it only confirms the part meets automotive industry reliability standards.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional variations exist (RT1206FRE071K91L: 3.10mm × 1.60mm; ERA-8AEB1911V: 3.20mm × 1.60mm), but these fall within standard PCB footprint tolerances and do not affect placement or soldering.

Q: Which part should be selected for new designs?

A: Selection depends on circuit requirements. For applications requiring standard tolerance and general-purpose performance, either part is acceptable. For designs requiring precision performance, automotive compliance, or long-term stability, ERA-8AEB1911V is the preferred choice.
