Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE079K53L are qualified based on the following criteria:

Electrical Compatibility:

• Identical resistance value: 9.53 kOhms
• Equal or tighter tolerance specification
• Equal or greater power rating: 0.25W minimum
• Matching or superior temperature coefficient performance
• Operating temperature range encompassing or exceeding -55°C to 155°C

Mechanical Compatibility:

• Identical package designation: 1206 (3216 Metric)
• Physical dimensions compatible with PCB footprints designed for 1206 components
• Two-terminal configuration maintained

Compliance & Certification:

• ROHS3 compliance maintained
• MSL rating of 1 or equivalent
• Active product status

The ERA-8AEB9531V qualifies as a direct substitute based on these parameters, offering enhanced tolerance specification (±0.1% versus ±1%) and automotive-grade AEC-Q200 certification while maintaining all core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

RT1206FRE079K53L (YAGEO): Select this part for standard applications requiring 9.53 kOhms ±1% resistance with 1206 package compatibility. The component is ROHS3 compliant with unlimited moisture sensitivity rating, suitable for general industrial and commercial applications.

ERA-8AEB9531V (Panasonic): Select this substitute for applications requiring enhanced tolerance specification (±0.1%) and automotive-grade reliability. The AEC-Q200 certification qualifies this part for automotive and high-reliability applications. The improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) provides superior stability across the operating temperature range. Both parts maintain identical power rating, package format, and compliance certifications.

Physical dimension variations (length 3.10mm versus 3.20mm, height 0.65mm versus 0.70mm) are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB9531V replace RT1206FRE079K53L in existing designs?

A: Yes. Both parts share identical resistance value (9.53 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C to 155°C). The ERA-8AEB9531V offers tighter tolerance (±0.1% versus ±1%) and superior temperature coefficient performance, making it a direct functional substitute. Physical dimensions remain within 1206 package specifications.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification (±1% versus ±0.1%), temperature coefficient (±50ppm/°C versus ±25ppm/°C), and certification level. The ERA-8AEB9531V includes AEC-Q200 automotive qualification, while the RT1206FRE079K53L is a standard industrial-grade component. Both maintain ROHS3 compliance and MSL 1 rating.

Q: Are there package compatibility concerns?

A: No. Both parts use the 1206 (3216 Metric) package with two terminations. Minor dimensional variations (length 3.10mm to 3.20mm, height 0.65mm to 0.70mm) fall within standard 1206 package tolerances and do not affect PCB footprint design or assembly compatibility.

Q: Which part should be selected for automotive applications?

A: The ERA-8AEB9531V is qualified for automotive use through AEC-Q200 certification. The RT1206FRE079K53L is suitable for general industrial and commercial applications without automotive-specific qualification.

Q: How do tolerance specifications affect circuit performance?

A: The RT1206FRE079K53L tolerance of ±1% allows resistance values between 9.4357 kOhms and 9.6243 kOhms. The ERA-8AEB9531V tolerance of ±0.1% constrains values between 9.5147 kOhms and 9.5453 kOhms. Tighter tolerance reduces circuit parameter variation and improves performance consistency in precision applications.
