Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07549KL is determined by the following mandatory parameters:

• Resistance value: 549 kOhms (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• Composition: Thin film (maintains electrical characteristics)
• RoHS compliance: ROHS3 or equivalent

Tolerance and temperature coefficient may be upgraded to tighter specifications without affecting substitutability. Physical dimensions may vary within industry standards for the 1206 package format.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRE07549KL (YAGEO) serves as a direct upgrade path, offering tighter tolerance (±0.5% versus ±1%) while maintaining identical power rating, package format, and operating temperature specifications. Both YAGEO parts share the same series designation and thermal characteristics.

ERA-8AEB5493V (Panasonic Electronic Components) provides the highest tolerance specification (±0.1%) with improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) and includes AEC-Q200 automotive qualification. This part is suitable for applications requiring enhanced precision and automotive-grade reliability. All three parts maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRE07549KL replace RT1206FRE07549KL in any application?

A: Yes. RT1206DRE07549KL is a direct substitute with superior tolerance specification. The tighter ±0.5% tolerance is backward-compatible with circuits designed for ±1% tolerance.

Q: What is the primary difference between YAGEO and Panasonic options?

A: The ERA-8AEB5493V from Panasonic offers tighter tolerance (±0.1%), lower temperature coefficient (±25ppm/°C), and AEC-Q200 automotive qualification. YAGEO parts are standard industrial-grade components without automotive certification.

Q: Are physical dimensions identical across all three parts?

A: All three parts conform to the 1206 (3216 Metric) package standard. Minor dimensional variations exist within industry tolerance: RT1206FRE07549KL and RT1206DRE07549KL measure 3.10mm × 1.60mm; ERA-8AEB5493V measures 3.20mm × 1.60mm. These variations are within standard PCB footprint tolerances.

Q: Which part should be selected for high-precision applications?

A: ERA-8AEB5493V is recommended for applications requiring tolerance better than ±0.5% and stable performance across temperature extremes, due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
