Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0735K7L are qualified based on the following electrical and mechanical parameters:

• Resistance Value: Must be 35.7 kOhms (exact match)
• Package Format: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W minimum
• Composition: Thin film construction
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: ROHS3 and REACH requirements

Tolerance and temperature coefficient are secondary parameters that may be improved in substitute parts without affecting functional compatibility. The RT1206BRD0735K7L offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). The ERA-8AEB3572V provides equivalent electrical performance with automotive AEC-Q200 qualification for applications requiring enhanced reliability standards.

Parameter Comparison

Engineering Selection Recommendations

RT1206FRE0735K7L (Original): Select for standard industrial applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit requirements. ROHS3 compliance and MSL 1 rating support general manufacturing environments.

RT1206BRD0735K7L (YAGEO Upgrade): Select when improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) are required for precision analog circuits or temperature-sensitive applications. Maintains YAGEO supply chain continuity with enhanced performance specifications.

ERA-8AEB3572V (Panasonic Automotive): Select for automotive applications, industrial equipment, or systems requiring AEC-Q200 qualification. Equivalent electrical performance with automotive-grade reliability certification. Dimensions vary slightly (0.126" L vs 0.122" L; 0.028" H vs 0.026" H maximum seated height).

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0735K7L replace RT1206FRE0735K7L directly on the PCB?

A: Yes. Both components use identical 1206 (3216 Metric) package format with matching footprint requirements. The RT1206BRD0735K7L is a direct mechanical and electrical substitute with improved tolerance and temperature coefficient specifications.

Q: Is ERA-8AEB3572V compatible with the same PCB footprint?

A: Yes, ERA-8AEB3572V uses the 1206 (3216 Metric) package. Dimensional variations are minor (length 0.126" vs 0.122"; maximum seated height 0.028" vs 0.026"). These differences do not affect standard PCB footprint compatibility but should be confirmed for applications with tight height constraints.

Q: What is the primary difference between the three parts?

A: RT1206FRE0735K7L offers standard tolerance (±1%) and temperature coefficient (±50ppm/°C). RT1206BRD0735K7L improves both specifications (±0.1% tolerance, ±25ppm/°C). ERA-8AEB3572V matches the upgraded specifications while adding AEC-Q200 automotive qualification.

Q: Which substitute should be used for automotive applications?

A: ERA-8AEB3572V is the appropriate selection for automotive applications due to AEC-Q200 qualification. This certification ensures compliance with automotive reliability and environmental stress testing requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE0735K7L, RT1206BRD0735K7L, and ERA-8AEB3572V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences between ±1% and ±0.1% affect circuit accuracy. Applications requiring tight resistance values for precision filtering, biasing, or analog signal conditioning should use RT1206BRD0735K7L or ERA-8AEB3572V. Standard tolerance (±1%) is acceptable for general-purpose applications.
