RT1206FRE07442RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07442RL 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 (1/4W) power dissipation with ±1% tolerance and operates across the 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 when equivalent electrical performance and mechanical compatibility can be maintained while potentially offering improved specifications such as tighter tolerance, enhanced temperature stability, or automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

The ERA-8AEB4420V from Panasonic Electronic Components qualifies as a direct substitute based on the following alignment of critical parameters:

• Resistance Value: Both parts specify 442 Ohms
• Package Format: Both use 1206 (3216 Metric) package
• Power Rating: Both rated at 0.25W (1/4W)
• Composition: Both are thin film resistors
• Operating Temperature Range: Both operate from -55°C to 155°C
• Compliance: Both are ROHS3 compliant with MSL 1 rating

The ERA-8AEB4420V represents an upgrade path due to improved tolerance (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C), with additional AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07442RL and ERA-8AEB4420V maintain Active product status and full ROHS3 compliance. Selection between these parts depends on application requirements:

The RT1206FRE07442RL is suitable for general-purpose applications where standard tolerance and temperature stability are acceptable.

The ERA-8AEB4420V is appropriate for applications requiring tighter tolerance control, improved temperature stability, or automotive-grade component qualification per AEC-Q200 standard. The superior temperature coefficient of ±25ppm/°C provides enhanced performance in temperature-sensitive circuits compared to the ±50ppm/°C specification of the YAGEO part.

Both components are physically compatible within the 1206 package footprint and share identical power ratings and operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB4420V replace RT1206FRE07442RL in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, package formats, and operating temperature ranges. The ERA-8AEB4420V offers improved tolerance and temperature coefficient specifications, making it a direct mechanical and electrical substitute.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance defines the maximum deviation from the nominal resistance value. The ±0.1% tolerance of the ERA-8AEB4420V provides tighter resistance accuracy compared to the ±1% tolerance of the RT1206FRE07442RL. Applications requiring precise resistance values benefit from the improved tolerance specification.

Q: Does the temperature coefficient difference affect circuit performance?

A: Temperature coefficient measures resistance change per degree Celsius. The ERA-8AEB4420V exhibits ±25ppm/°C compared to ±50ppm/°C for the RT1206FRE07442RL. In circuits operating across wide temperature ranges, the lower temperature coefficient of the Panasonic part results in more stable resistance values and improved circuit performance.

Q: Are there physical dimension differences between these parts?

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional variations exist: RT1206FRE07442RL measures 0.122" L x 0.063" W with 0.026" maximum seated height, while ERA-8AEB4420V measures 0.126" L x 0.063" W with 0.028" maximum seated height. These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: What does AEC-Q200 qualification indicate?

A: AEC-Q200 is an automotive industry standard qualification for passive components. The ERA-8AEB4420V carries this certification, indicating compliance with automotive reliability and performance requirements. This qualification is relevant for automotive applications but not required for general industrial or consumer applications.

Q: Are both parts RoHS compliant?

A: Yes. Both RT1206FRE07442RL and ERA-8AEB4420V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for commercial and industrial applications.
