RT1206FRE073K74L Equivalent & Substitute Parts

Part Overview

The RT1206FRE073K74L is a 3.74 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant. Substitute parts are identified to provide alternatives with improved tolerance specifications or enhanced automotive qualification where application requirements permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE073K74L is determined by the following critical parameters:

• Resistance value: Must be 3.74 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power rating: Must be 0.25W (1/4W) minimum
• Composition: Thin film technology
• Operating temperature range: Must cover -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant

The ERA-8AEB3741V qualifies as a direct substitute based on matching all mandatory parameters. Enhanced specifications (±0.1% tolerance vs. ±1%, ±25ppm/°C vs. ±50ppm/°C, and AEC-Q200 automotive qualification) represent improvements over the original part and do not restrict substitution in applications where the original part was specified.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with ROHS3 compliance and identical moisture sensitivity ratings. The ERA-8AEB3741V provides tighter tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), with additional AEC-Q200 automotive qualification. Selection between these parts depends on application-specific requirements for tolerance precision and automotive environment exposure. Both parts are mechanically and electrically compatible within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3741V replace RT1206FRE073K74L in all applications?

A: Yes, provided the application does not explicitly prohibit substitution. The ERA-8AEB3741V meets or exceeds all electrical and mechanical parameters of the original part. Tighter tolerance and lower temperature coefficient represent performance improvements.

Q: Are there physical dimension differences between these parts?

A: Both parts use the 1206 (3216 Metric) package. Slight variations exist in seated height (0.65mm vs. 0.70mm maximum) and length (3.10mm vs. 3.20mm), which remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of AEC-Q200 qualification on the ERA-8AEB3741V?

A: AEC-Q200 indicates automotive-grade qualification per industry standards. This certification is relevant only if the application requires automotive-grade components. For non-automotive applications, this qualification does not affect substitution eligibility.

Q: Do both parts have identical moisture sensitivity?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
