Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Resistance Value: Must be 866 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.25W minimum
• Composition: Thin film technology
• Operating Temperature Range: Must cover -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 Compliant

Tolerance and temperature coefficient may vary within substitute parts, provided they do not degrade circuit performance. Automotive-grade certifications (AEC-Q200) represent enhanced reliability options.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRE07866KL (YAGEO): Direct upgrade path offering improved tolerance (±0.5% vs ±1%) while maintaining identical power rating, package, and temperature range. Both components are standard-grade YAGEO products with equivalent RoHS3 compliance and MSL ratings.

ERA-8AEB8663V (Panasonic): Highest-precision option with ±0.1% tolerance and superior temperature coefficient (±25ppm/°C vs ±50ppm/°C). Includes AEC-Q200 automotive qualification. Dimensions vary slightly (3.20mm L vs 3.10mm L; 0.70mm H vs 0.65mm H), requiring PCB layout verification. Suitable for applications requiring automotive-grade reliability or precision analog circuits.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRE07866KL replace RT1206FRE07866KL directly?

A: Yes. Both components share identical resistance, power rating, package, and operating temperature range. The improved tolerance (±0.5%) is a functional enhancement with no compatibility impact.

Q: Is ERA-8AEB8663V a direct mechanical substitute?

A: Electrical compatibility is confirmed. Physical dimensions differ slightly: ERA-8AEB8663V is 3.20mm L × 1.60mm W × 0.70mm H versus RT1206FRE07866KL at 3.10mm L × 1.60mm W × 0.65mm H. PCB footprint and clearance verification is required before substitution.

Q: What is the significance of AEC-Q200 certification on ERA-8AEB8663V?

A: AEC-Q200 indicates automotive-grade qualification and enhanced reliability testing. This certification is relevant only for applications requiring automotive compliance; standard industrial applications do not require this qualification.

Q: Can tolerance differences affect circuit performance?

A: Tolerance impact depends on circuit design. Applications with tight resistance specifications benefit from lower tolerance values (±0.5% or ±0.1%). Standard tolerance (±1%) is adequate for general-purpose filtering, biasing, and signal conditioning circuits.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three components are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
