RT1206CRE07255RL Equivalent & Substitute Parts

Part Overview

The RT1206CRE07255RL is a 255 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 temperature range of -55°C to 155°C. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent resistance values, package formats, power ratings, and operating temperature ranges are maintained while potentially offering improved electrical characteristics or specialized certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE07255RL is determined by the following criteria:

• Resistance value must equal 255 Ohms
• Package format must be 1206 (3216 Metric)
• Power rating must be 0.25W or greater
• Operating temperature range must encompass -55°C to 155°C
• Composition must be thin film
• RoHS3 compliance required

The ERA-8AEB2550V qualifies as a substitute part. While it offers improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent enhanced electrical characteristics that maintain backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206CRE07255RL and ERA-8AEB2550V maintain Active product status with full regulatory compliance. The ERA-8AEB2550V carries AEC-Q200 automotive qualification, which indicates suitability for automotive applications requiring enhanced reliability standards. Selection between these parts should be based on application requirements: the YAGEO part is suitable for general industrial applications, while the Panasonic part is specified for automotive environments where AEC-Q200 certification is required or preferred.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB2550V directly replace the RT1206CRE07255RL?

A: Yes. Both parts share identical resistance values (255 Ohms), power ratings (0.25W), package formats (1206), operating temperature ranges (-55°C to 155°C), and composition (thin film). The ERA-8AEB2550V offers tighter tolerance and lower temperature coefficient, making it functionally compatible for direct substitution.

Q: What is the significance of the ±0.1% tolerance on the ERA-8AEB2550V compared to ±0.25% on the RT1206CRE07255RL?

A: The ERA-8AEB2550V provides improved tolerance, meaning its actual resistance value will remain closer to the nominal 255 Ohm specification across production batches. This enhanced precision may be beneficial in precision analog circuits or measurement applications where tighter component tolerances are required.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The RT1206CRE07255RL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with a maximum seated height of 0.026" (0.65mm). The ERA-8AEB2550V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with a maximum seated height of 0.028" (0.70mm). These differences are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard indicating the component has been tested and approved for use in automotive applications. The ERA-8AEB2550V carries this certification, making it suitable for automotive-grade designs where such qualification is mandated.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RT1206CRE07255RL and ERA-8AEB2550V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements for commercial and industrial applications.
