RT1206CRE07137RL Equivalent & Substitute Parts

Part Overview

The RT1206CRE07137RL is a 137 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 with an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, package format, and power rating while meeting or exceeding the original specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE07137RL is determined by the following criteria:

• Resistance value must be 137 Ohms
• Package must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility
• Power rating must be 0.25W (1/4W) or greater
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• Tolerance may be equal to or tighter than ±0.25%
• RoHS3 compliance required

The ERA-8AEB1370V meets all substitution criteria with improved tolerance specification (±0.1% versus ±0.25%) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB1370V qualifies as a direct substitute for the RT1206CRE07137RL based on matching electrical specifications and package compatibility. The substitute part offers improved tolerance performance (±0.1% versus ±0.25%) and includes automotive-grade AEC-Q200 qualification. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts should be based on application requirements for tolerance precision and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB1370V be used as a direct replacement for the RT1206CRE07137RL?

A: Yes. Both parts share identical resistance value (137 Ohms), package format (1206), power rating (0.25W), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute part meets or exceeds all electrical and mechanical specifications of the original part.

Q: What are the physical dimension differences between these parts?

A: The RT1206CRE07137RL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB1370V measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.028" (0.70mm). Both dimensions remain within 1206 package specifications and are compatible with standard PCB layouts.

Q: Does the improved tolerance of the ERA-8AEB1370V affect circuit performance?

A: The ERA-8AEB1370V provides tighter tolerance (±0.1% versus ±0.25%), which reduces resistance value variation. This improvement does not negatively affect circuit performance and may enhance precision in applications requiring closer component tolerances.

Q: Are both parts suitable for automotive applications?

A: The ERA-8AEB1370V carries AEC-Q200 automotive qualification. The RT1206CRE07137RL does not specify automotive qualification. Selection depends on application requirements for automotive-grade components.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-8AEB1370V has a temperature coefficient of ±25ppm/°C compared to ±50ppm/°C for the RT1206CRE07137RL. This means the substitute part exhibits lower resistance variation across the operating temperature range, providing improved stability in temperature-sensitive applications.
