RT1206FRE07422RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07422RL is a 422 Ohm ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternatives for procurement flexibility, inventory management, or when enhanced specifications such as improved tolerance or automotive qualification are required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07422RL is determined by the following critical parameters:

• Resistance value must be 422 Ohms
• Package format must be 1206 (3216 Metric)
• Power rating must be 0.25W (1/4W) minimum
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance required

The ERA-8AEB4220V qualifies as a direct substitute based on these parameters. While it offers enhanced tolerance (±0.1% versus ±1%) and automotive AEC-Q200 qualification, these represent improvements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB4220V (Panasonic) is a qualified substitute for the RT1206FRE07422RL. Both parts maintain Active product status and ROHS3 compliance. The Panasonic part provides tighter tolerance control (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), along with AEC-Q200 automotive qualification. These characteristics make the ERA-8AEB4220V suitable for applications requiring enhanced precision or automotive-grade reliability without compromising electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB4220V replace the RT1206FRE07422RL in existing designs?

A: Yes. Both parts share identical resistance value (422 Ohms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB4220V meets or exceeds all electrical and mechanical requirements of the original part.

Q: What are the key differences between these two parts?

A: The ERA-8AEB4220V offers improved tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. The physical dimensions differ slightly (3.20mm x 1.60mm versus 3.10mm x 1.60mm length, and 0.70mm versus 0.65mm maximum seated height), though both conform to the 1206 package specification.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. Both parts use the 1206 (3216 Metric) package format with identical termination count (2 terminations) and are suitable for standard surface mount assembly processes. Minor dimensional variations fall within normal 1206 package tolerances.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For general-purpose applications, either part is acceptable. For applications requiring tighter tolerance control, lower temperature drift, or automotive-grade reliability, the ERA-8AEB4220V is the preferred choice.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the RT1206FRE07422RL and ERA-8AEB4220V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
