RT1206FRE073K6L Equivalent & Substitute Parts

Part Overview

The RT1206FRE073K6L is a 3.6 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status with 976 units in stock.

Substitute parts are identified when they maintain the same resistance value, package form factor, and power rating while offering improved electrical characteristics such as tighter tolerance or lower temperature coefficient, or when they provide equivalent performance with additional certifications such as automotive qualification.

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE073K6L are qualified based on the following criteria:

Primary Substitution Parameters:

• Resistance value: 3.6 kOhms (exact match required)
• Package: 1206 (3216 Metric) form factor
• Power rating: 0.25W minimum
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 or equivalent

Secondary Qualification Criteria:

• Tolerance: Equal to or tighter than ±1%
• Temperature coefficient: Equal to or lower than ±50ppm/°C
• Compliance certifications: Product status active, MSL 1 rating

Two substitute parts meet these criteria: RT1206BRD073K6L (YAGEO) and ERA-8AEB362V (Panasonic Electronic Components). Both maintain identical resistance, package, and power specifications while offering improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD073K6L (YAGEO): This part provides direct substitution with improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). Both parts are manufactured by YAGEO within the same RT series, ensuring design continuity. ROHS3 compliance and MSL 1 rating are maintained. This option is suitable for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB362V (Panasonic Electronic Components): This part offers equivalent electrical performance to RT1206BRD073K6L with the addition of AEC-Q200 automotive qualification. The ±0.1% tolerance and ±25ppm/°C temperature coefficient match the YAGEO upgrade option. Physical dimensions differ slightly (0.126" L x 0.063" W vs 0.122" L x 0.063" W, with 0.028" max height vs 0.026" max height), remaining within 1206 package classification. This option is required for automotive applications or systems requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD073K6L directly replace RT1206FRE073K6L in my circuit?

A: Yes. Both parts share identical resistance (3.6 kOhms), power rating (0.25W), package (1206), and operating temperature range (-55°C to 155°C). RT1206BRD073K6L offers improved tolerance and temperature coefficient, making it a direct upgrade with no circuit redesign required.

Q: What is the difference between RT1206BRD073K6L and ERA-8AEB362V?

A: Both parts provide 3.6 kOhms ±0.1% with ±25ppm/°C temperature coefficient. The primary difference is that ERA-8AEB362V carries AEC-Q200 automotive qualification, required for automotive applications. Physical dimensions are slightly different but both conform to 1206 package specifications.

Q: Which substitute should I use for automotive applications?

A: ERA-8AEB362V is the appropriate choice for automotive applications due to AEC-Q200 certification. RT1206BRD073K6L and RT1206FRE073K6L lack automotive qualification and should not be used in automotive systems.

Q: Are there any PCB layout considerations when switching between these parts?

A: All three parts use the 1206 (3216 Metric) package with identical footprints. Physical dimensions are within acceptable tolerance for standard 1206 land patterns. No PCB layout modifications are required.

Q: What does the ±1% vs ±0.1% tolerance difference mean for my application?

A: Tolerance specifies the maximum deviation from the nominal 3.6 kOhms value. RT1206FRE073K6L allows ±36 ohms deviation (3564-3636 ohms range), while RT1206BRD073K6L and ERA-8AEB362V allow ±3.6 ohms deviation (3596.4-3603.6 ohms range). Tighter tolerance is beneficial for precision analog circuits and measurement applications.

Q: What does temperature coefficient mean and why does it matter?

A: Temperature coefficient (±50ppm/°C vs ±25ppm/°C) indicates how much the resistance changes per degree Celsius. Lower values indicate better stability across temperature extremes. At 100°C temperature change, RT1206FRE073K6L could drift ±5000ppm (±0.5%), while RT1206BRD073K6L and ERA-8AEB362V would drift ±2500ppm (±0.25%). Critical for precision applications operating across wide temperature ranges.
