Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Resistance Value: Must be 154 kOhms (exact match required)
• Package Format: Must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power Rating: Must be 0.25W minimum
• Composition: Thin film technology maintained across all substitutes
• Operating Temperature Range: Must cover -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required

Tolerance and temperature coefficient are secondary parameters that may be improved in substitute parts without affecting compatibility. Automotive certifications (AEC-Q200) are optional enhancements that do not restrict substitution.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07154KL (YAGEO): This substitute offers improved tolerance (±0.1% versus ±1%) and superior temperature coefficient stability (±25ppm/°C versus ±50ppm/°C) while maintaining identical package dimensions and power rating. Selection is appropriate for applications requiring tighter resistance accuracy without automotive-specific requirements.

ERA-8AEB1543V (Panasonic): This substitute provides the same tolerance and temperature coefficient improvements as the RT1206BRD07154KL, with the addition of AEC-Q200 automotive qualification. Physical dimensions are marginally larger (0.126" L × 0.063" W versus 0.122" L × 0.063" W; height 0.028" versus 0.026"), but remain compatible with standard 1206 footprints. Selection is appropriate for automotive applications or environments requiring automotive-grade component reliability.

All three parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature ranges, ensuring direct substitution capability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07154KL be used as a direct replacement for RT1206FRE07154KL?

A: Yes. Both components share identical resistance value (154 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C to 155°C). The RT1206BRD07154KL provides improved tolerance (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a compatible upgrade.

Q: What are the physical dimension differences between ERA-8AEB1543V and the YAGEO parts?

A: ERA-8AEB1543V dimensions are 0.126" L × 0.063" W × 0.028" H (max), compared to 0.122" L × 0.063" W × 0.026" H (max) for the YAGEO parts. These differences are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Is AEC-Q200 certification required for this application?

A: AEC-Q200 certification is required only for automotive applications. For general-purpose electronics, standard-grade parts (RT1206FRE07154KL or RT1206BRD07154KL) are sufficient. ERA-8AEB1543V should be selected only when automotive qualification is a design requirement.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, within the constraints of your circuit's tolerance and temperature stability requirements. If your design specifies ±1% tolerance, all three parts are compatible. If tighter tolerance is required, RT1206BRD07154KL or ERA-8AEB1543V must be used.

Q: What is the inventory status for each substitute?

A: RT1206FRE07154KL: 931 Pcs in stock; RT1206BRD07154KL: 6032 Pcs in stock; ERA-8AEB1543V: 10809 Pcs in stock. Availability should be verified with your supplier for current stock levels.
