RT1206CRE07442RL Equivalent & Substitute Parts

Part Overview

The RT1206CRE07442RL is a 442 Ohm thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W power dissipation with ±0.25% tolerance and operates across the -55°C to 155°C temperature range. The part is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative sourcing options that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE07442RL is determined by the following critical parameters:

• Resistance value: 442 Ohms (exact match required)
• Package format: 1206 (3216 Metric) with compatible physical dimensions
• Power rating: Minimum 0.25W
• Composition: Thin film construction
• Operating temperature range: Must encompass -55°C to 155°C
• Regulatory compliance: ROHS3 and REACH status alignment

The ERA-8AEB4420V qualifies as a direct substitute based on matching all core electrical specifications and package requirements. This part maintains the same resistance value, package footprint, power rating, and operating temperature range while offering improved tolerance performance (±0.1% versus ±0.25%) and enhanced temperature coefficient stability (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206CRE07442RL and ERA-8AEB4420V maintain active production status and full regulatory compliance under ROHS3 and REACH requirements. The ERA-8AEB4420V incorporates Automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade component standards.

The dimensional variance between the two parts is minimal. The ERA-8AEB4420V exhibits a maximum length increase of 0.004" (0.10mm) and height increase of 0.002" (0.05mm) relative to the main part. These differences remain within typical PCB layout tolerances for 1206 package footprints and do not necessitate design modifications for standard applications.

Selection between these parts should be based on availability, cost considerations, and application-specific requirements for tolerance precision and temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB4420V be used as a direct replacement for the RT1206CRE07442RL on existing PCBs?

A: Yes. Both parts share the 1206 (3216 Metric) package format with compatible footprints. The dimensional differences (0.004" length and 0.002" height variance) fall within standard PCB design tolerances and do not require layout modifications.

Q: What is the significance of the tolerance difference between ±0.25% and ±0.1%?

A: The ERA-8AEB4420V provides tighter tolerance control, resulting in more precise resistance values across the production batch. This is beneficial for applications requiring high accuracy in voltage dividers, precision measurement circuits, or filter networks where tolerance stack-up is a design consideration.

Q: Does the temperature coefficient difference affect circuit performance?

A: The ERA-8AEB4420V exhibits a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), meaning its resistance value remains more stable across temperature variations. This is advantageous in applications operating across wide temperature ranges or requiring stable gain and frequency response characteristics.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB4420V carries Automotive AEC-Q200 qualification. The RT1206CRE07442RL does not specify automotive qualification. For automotive applications, the ERA-8AEB4420V is the appropriate selection.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The 1206 package dimensions are compatible with standard pick-and-place equipment and reflow soldering processes.
