RT1206FRE0746K4L Equivalent & Substitute Parts

Part Overview

The RT1206FRE0746K4L is a 46.4 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W power dissipation. This YAGEO component operates across -55°C to 155°C and is ROHS3 compliant with unlimited moisture sensitivity rating. The part is currently active in production with substantial inventory availability. Substitute parts are identified to address applications requiring tighter tolerance specifications, enhanced temperature stability, or automotive-grade qualification while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0746K4L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 46.4 kOhms
• Power rating: 0.25W minimum
• Package type: 1206 (3216 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum

Allowable Variations:

• Tolerance may be tighter (±0.1% acceptable for ±1% requirement)
• Temperature coefficient may be lower (±25ppm/°C acceptable for ±50ppm/°C requirement)
• Mechanical dimensions within standard 1206 tolerances
• Additional certifications (AEC-Q200) do not disqualify substitution

Compliance Requirements:

• ROHS3 compliance maintained
• MSL rating 1 or better
• REACH unaffected status

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD0746K4L (YAGEO): Direct upgrade within the same manufacturer series. Provides improved tolerance specification (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package, power rating, and operating range. Suitable for applications requiring enhanced precision without automotive qualification requirements.

ERA-8AEB4642V (Panasonic): Functionally equivalent substitute with AEC-Q200 automotive qualification. Delivers identical electrical performance to RT1206BRD0746K4L with additional automotive-grade reliability certification. Mechanical dimensions vary slightly within standard tolerances (3.20mm L vs 3.10mm L; 0.70mm H vs 0.65mm H). Appropriate for automotive applications or systems requiring automotive-grade component qualification.

Both substitute parts maintain full compliance with ROHS3 and REACH requirements, with unlimited moisture sensitivity rating equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0746K4L replace RT1206FRE0746K4L in any application?

A: Yes. RT1206BRD0746K4L meets all electrical and mechanical requirements of RT1206FRE0746K4L. The tighter tolerance and lower temperature coefficient represent performance improvements compatible with any circuit designed for the original part.

Q: What is the difference between the two YAGEO parts?

A: RT1206BRD0746K4L offers ±0.1% tolerance and ±25ppm/°C temperature coefficient compared to RT1206FRE0746K4L's ±1% tolerance and ±50ppm/°C coefficient. Both share identical 1206 package, 0.25W rating, and operating temperature range.

Q: Is ERA-8AEB4642V suitable for non-automotive applications?

A: Yes. ERA-8AEB4642V meets all electrical specifications required for the original part. AEC-Q200 certification is an additional qualification that does not restrict use in standard industrial or consumer applications.

Q: Are there mechanical compatibility concerns with ERA-8AEB4642V?

A: ERA-8AEB4642V dimensions (3.20mm L x 1.60mm W x 0.70mm H) differ slightly from RT1206FRE0746K4L (3.10mm L x 1.60mm W x 0.65mm H). Both conform to 1206 package standard tolerances and are mechanically compatible with standard 1206 footprints.

Q: Do all three parts share the same tape and reel packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: What compliance certifications apply to all substitute parts?

A: All parts maintain ROHS3 compliance, REACH unaffected status, MSL rating 1 (unlimited), and EAR99 export classification.
