RT1206FRE07137KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07137KL is a 137 kOhms ±1% 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 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 resistance values, package formats, power ratings, and operating temperature ranges align with the original specification, while potentially offering improved tolerance, temperature coefficient performance, or enhanced reliability certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07137KL is determined by the following critical parameters:

• Resistance value: 137 kOhms (exact match required)
• Package format: 1206 (3216 Metric) with 2 terminations
• Power rating: 0.25W minimum
• Operating temperature range: -55°C to 155°C minimum coverage
• Composition: Thin film construction
• Compliance: ROHS3 and REACH requirements

The ERA-8AEB1373V qualifies as a direct substitute based on matching all mandatory parameters. This part maintains identical resistance, package, power rating, and operating temperature specifications while offering enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07137KL and ERA-8AEB1373V maintain Active product status and satisfy ROHS3 compliance requirements. The ERA-8AEB1373V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on application-specific tolerance and temperature stability requirements, with the ERA-8AEB1373V offering superior performance in both tolerance (±0.1%) and temperature coefficient (±25ppm/°C) specifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1373V be used as a direct replacement for RT1206FRE07137KL?

A: Yes. Both parts share identical resistance values (137 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB1373V provides equivalent or superior electrical performance.

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

A: RT1206FRE07137KL dimensions are 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). ERA-8AEB1373V dimensions are 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). Both fit the 1206 package specification and are compatible with standard PCB layouts.

Q: What is the significance of the tolerance difference?

A: RT1206FRE07137KL specifies ±1% tolerance, while ERA-8AEB1373V specifies ±0.1% tolerance. The tighter tolerance of the ERA-8AEB1373V provides greater resistance value accuracy, beneficial for precision analog circuits and applications with strict component value requirements.

Q: Does the temperature coefficient difference affect substitution suitability?

A: Both parts operate across -55°C to 155°C. The ERA-8AEB1373V temperature coefficient of ±25ppm/°C is superior to the RT1206FRE07137KL at ±50ppm/°C, resulting in better resistance stability across temperature variations. This makes the ERA-8AEB1373V suitable for temperature-sensitive applications.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
