Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0744K2L is determined by the following criteria:

• Identical resistance value: 44.2 kOhms
• Equal or tighter tolerance specification (±1% or better)
• Identical power rating: 0.25W (1/4W)
• Identical package: 1206 (3216 Metric)
• Thin film composition
• Operating temperature range encompassing -55°C to 155°C
• Tape & Reel packaging format
• RoHS3 compliance

The ERA-8AEB4422V meets all substitution criteria with an upgrade in tolerance specification (±0.1% versus ±1%) and includes automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB4422V qualifies as a direct substitute for the RT1206FRE0744K2L based on matching electrical specifications, identical package geometry, and equivalent environmental ratings. The substitute component provides improved tolerance performance (±0.1% versus ±1%) and includes automotive AEC-Q200 qualification, which extends application suitability to automotive environments while maintaining full compatibility with the original specification.

Both components maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating. The identical operating temperature range (-55°C to 155°C) and packaging format (Tape & Reel) ensure seamless integration into existing procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB4422V be used as a direct replacement for the RT1206FRE0744K2L?

A: Yes. Both components share identical resistance value (44.2 kOhms), power rating (0.25W), package type (1206), and operating temperature range (-55°C to 155°C). The ERA-8AEB4422V provides tighter tolerance (±0.1%) and automotive qualification without compromising compatibility.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE0744K2L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB4422V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). Both fit the 1206 (3216 Metric) package specification and are compatible with standard 1206 footprints.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. The ERA-8AEB4422V includes automotive AEC-Q200 qualification, which the RT1206FRE0744K2L does not specify. This additional qualification does not restrict use in non-automotive applications.

Q: What is the significance of the tolerance difference?

A: The RT1206FRE0744K2L carries ±1% tolerance, while the ERA-8AEB4422V carries ±0.1% tolerance. The tighter tolerance of the substitute component provides improved accuracy and stability, representing an upgrade in precision performance.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the RT1206FRE0744K2L and ERA-8AEB4422V are supplied in Tape & Reel (TR) format, ensuring compatibility with automated assembly equipment and standard component handling processes.
