Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE071K87L is determined by the following critical parameters:

• Resistance value: 1.87 kOhms (exact match required)
• Package: 1206 (3216 Metric) form factor
• Power rating: 0.25W minimum
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum coverage
• Termination count: 2 terminations
• Compliance: ROHS3 and REACH requirements

The ERA-8AEB1871V from Panasonic Electronic Components meets all substitution criteria. While it features 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 specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE071K87L and ERA-8AEB1871V are active production components with full ROHS3 compliance and REACH unaffected status. The ERA-8AEB1871V carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. Selection between these parts should be based on application requirements: the YAGEO part for standard industrial applications, and the Panasonic part for automotive or high-precision applications where tighter tolerance and lower temperature coefficient provide performance advantages.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1871V replace RT1206FRE071K87L in all applications?

A: Yes, from an electrical and mechanical standpoint. The ERA-8AEB1871V meets all core substitution criteria: identical resistance value, package type, power rating, and operating temperature range. The improved tolerance and temperature coefficient represent performance enhancements.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist. The RT1206FRE071K87L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. The ERA-8AEB1871V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit the 1206 package specification; verify PCB layout clearances for critical applications.

Q: What is the significance of the ±0.1% tolerance in the Panasonic part?

A: The ERA-8AEB1871V provides tighter tolerance control compared to the ±1% specification of the YAGEO part. This is beneficial in precision analog circuits, measurement equipment, and applications where component value drift impacts performance.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 155°C. The ERA-8AEB1871V has a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), resulting in better resistance stability across temperature extremes.

Q: What does AEC-Q200 qualification mean for the Panasonic part?

A: AEC-Q200 is an automotive industry standard for passive components. The ERA-8AEB1871V meets this qualification, indicating it has undergone rigorous testing for automotive applications including thermal cycling, vibration, and reliability requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided PCB layout accommodates the minor dimension differences noted above. Both parts use identical 1206 package footprints and Tape & Reel packaging format, supporting direct substitution in manufacturing processes.
