RT1206FRE07180KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07180KL is a 180 kOhms ±1% 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 active in production status and ROHS3 compliant. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while allowing variations in tolerance, temperature coefficient, and manufacturer-specific features.

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE07180KL are qualified based on the following criteria:

Resistance Value: Must be 180 kOhms
Package / Case: Must be 1206 (3216 Metric)
Power Rating: Must be 0.25W (1/4W)
Composition: Must be Thin Film
Operating Temperature Range: Must be -55°C ~ 155°C
RoHS Compliance: Must be ROHS3 Compliant
Moisture Sensitivity Level: Must be 1 (Unlimited)

Variations allowed in substitute parts include tolerance (tighter tolerances are acceptable), temperature coefficient (lower values indicate better stability), and manufacturer-specific features such as automotive qualification (AEC-Q200) or anti-sulfur properties. All substitute parts maintain mechanical and electrical compatibility with the original part.

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance. Selection between substitute parts depends on application-specific requirements:

RT1206BRD07180KL and RT1206DRE07180KL are YAGEO alternatives offering tighter tolerance specifications (±0.1% and ±0.5% respectively) compared to the original ±1% tolerance, with improved temperature coefficient stability in the case of RT1206BRD07180KL (±25ppm/°C versus ±50ppm/°C).

ERA-8AEB184V (Panasonic) provides automotive AEC-Q200 qualification with ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for applications requiring automotive-grade reliability.

RG3216P-1803-B-T5 (Susumu) combines automotive AEC-Q200 qualification with anti-sulfur properties and ±0.1% tolerance, offering enhanced environmental resistance for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07180KL replace RT1206FRE07180KL directly?

A: Yes. Both parts share identical resistance value (180 kOhms), power rating (0.25W), package (1206), and operating temperature range (-55°C ~ 155°C). RT1206BRD07180KL offers improved tolerance (±0.1% versus ±1%) and better temperature coefficient stability (±25ppm/°C versus ±50ppm/°C).

Q: What is the difference between ERA-8AEB184V and RG3216P-1803-B-T5?

A: Both parts are automotive AEC-Q200 qualified with ±0.1% tolerance and ±25ppm/°C temperature coefficient. RG3216P-1803-B-T5 includes anti-sulfur properties for enhanced environmental resistance. Physical dimensions differ slightly: ERA-8AEB184V is 0.126" L x 0.063" W with 0.028" max height; RG3216P-1803-B-T5 is 0.126" L x 0.063" W with 0.020" max height.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original RT1206FRE07180KL specifications.

Q: Which substitute part offers the best tolerance?

A: RT1206BRD07180KL, ERA-8AEB184V, and RG3216P-1803-B-T5 all offer ±0.1% tolerance, which is tighter than the original ±1% specification.

Q: Can I use an automotive-qualified part in a non-automotive application?

A: Yes. Automotive-qualified parts (ERA-8AEB184V and RG3216P-1803-B-T5) meet or exceed standard industrial specifications and are suitable for any application within their rated parameters.
