Equivalent & Substitute Parts for RT1206CRE07180RL

Part Overview

The RT1206CRE07180RL is a 180 Ohms ±0.25% thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained while potentially offering improved tolerance specifications or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value must equal 180 Ohms
• Package must be 1206 (3216 Metric) for mechanical and electrical compatibility
• Power rating must be ≥0.25W
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance required
• MSL rating must be ≤1

Substitute parts may differ in tolerance specification (tighter tolerance acceptable), temperature coefficient (lower values acceptable), and may include additional certifications such as automotive AEC-Q200 qualification. These variations represent upgrades or specialized variants suitable for the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07180RL represents a direct upgrade from RT1206CRE07180RL, offering improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Both parts are manufactured by YAGEO and carry ROHS3 compliance.

ERA-8AEB181V provides equivalent electrical specifications to RT1206BRD07180RL with the addition of AEC-Q200 automotive qualification. This part is manufactured by Panasonic Electronic Components and is suitable for applications requiring automotive-grade reliability. Dimensional variations exist: ERA-8AEB181V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm), compared to standard 1206 dimensions of 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). These minor dimensional differences remain within 1206 package classification but should be verified for space-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07180RL be used as a direct replacement for RT1206CRE07180RL?

A: Yes. Both parts share identical resistance value, power rating, package, composition, and operating temperature range. RT1206BRD07180RL offers improved tolerance and temperature coefficient specifications, making it a suitable upgrade.

Q: What is the primary difference between RT1206BRD07180RL and ERA-8AEB181V?

A: Both parts provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. The primary difference is manufacturer and certification: ERA-8AEB181V includes AEC-Q200 automotive qualification from Panasonic Electronic Components, while RT1206BRD07180RL is a standard industrial-grade part from YAGEO. Minor dimensional variations also exist between the two parts.

Q: Are dimensional differences between ERA-8AEB181V and standard 1206 parts significant?

A: ERA-8AEB181V dimensions (3.20mm × 1.60mm, 0.70mm height) differ slightly from standard 1206 specifications (3.10mm × 1.60mm, 0.65mm height). These differences remain within 1206 package classification but should be verified for PCB layouts with tight component spacing or height restrictions.

Q: Can these substitute parts be used in automotive applications?

A: ERA-8AEB181V carries AEC-Q200 automotive qualification and is suitable for automotive applications. RT1206CRE07180RL and RT1206BRD07180RL are standard industrial-grade parts without automotive certification and should not be specified for automotive applications requiring AEC-Q200 compliance.

Q: What is the significance of ±0.1% tolerance versus ±0.25% tolerance?

A: Tolerance specifies the maximum allowable deviation from the nominal 180 Ohms resistance value. ±0.1% tolerance (RT1206BRD07180RL, ERA-8AEB181V) provides tighter resistance accuracy than ±0.25% tolerance (RT1206CRE07180RL), resulting in ±0.18 Ohms versus ±0.45 Ohms maximum deviation. Tighter tolerance is beneficial for precision analog circuits and impedance-critical applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206CRE07180RL, RT1206BRD07180RL, and ERA-8AEB181V are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).
