RT1206FRE0736K5L Equivalent & Substitute Parts

Part Overview

The RT1206FRE0736K5L is a 36.5 kOhms ±1% thin film chip resistor manufactured by YAGEO in 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating 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, and power ratings are maintained while offering improved tolerance specifications or enhanced reliability features such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0736K5L are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 36.5 kOhms
• Package format: 1206 (3216 Metric)
• Power rating: 0.25W (1/4W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance may be equal to or tighter than ±1%
• Temperature coefficient may be equal to or lower than ±50ppm/°C
• Physical dimensions may vary within supplier specifications
• Additional features (automotive qualification, anti-sulfur coating) are permitted enhancements

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

ERA-8AEB3652V (Panasonic Electronic Components) is suitable for applications requiring automotive-grade reliability. This part offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. AEC-Q200 qualification indicates suitability for automotive environments.

RG3216P-3652-B-T5 (Susumu) provides the same tolerance and temperature coefficient improvements as the Panasonic option, with the addition of anti-sulfur coating. AEC-Q200 qualification is included. This part is appropriate for applications in corrosive or high-sulfur environments where extended component life is required.

Both substitute parts are Active products with ROHS3 compliance and unlimited moisture sensitivity rating, matching the compliance profile of the original RT1206FRE0736K5L.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3652V or RG3216P-3652-B-T5 be used as direct replacements for RT1206FRE0736K5L?

A: Yes. Both parts maintain the same 36.5 kOhms resistance, 0.25W power rating, 1206 package format, and -55°C to 155°C operating temperature range. The tighter tolerance and lower temperature coefficient of the substitute parts represent performance improvements rather than incompatibilities.

Q: What is the significance of the ±0.1% tolerance in the substitute parts?

A: The substitute parts offer tolerance four times tighter than the original ±1% specification. This means resistance values will remain closer to the nominal 36.5 kOhms across the operating temperature range and manufacturing process variations, resulting in improved circuit accuracy.

Q: Why do the substitute parts have lower temperature coefficients?

A: Temperature coefficient (±25ppm/°C versus ±50ppm/°C) indicates how much the resistance value changes per degree Celsius. Lower values mean the resistance remains more stable across the -55°C to 155°C operating range, improving circuit performance in temperature-sensitive applications.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies components for use in automotive applications. Both substitute parts meet this standard, making them suitable for automotive circuit designs where reliability and environmental stress testing compliance are required.

Q: What is the anti-sulfur coating on the RG3216P-3652-B-T5?

A: Anti-sulfur coating protects the component from corrosion caused by hydrogen sulfide exposure in industrial or harsh environments. This feature extends component lifespan in applications subject to high-sulfur atmospheric conditions.

Q: Are there any physical dimension differences between these parts?

A: Minor variations exist within supplier specifications. The RT1206FRE0736K5L has a maximum seated height of 0.026" (0.65mm), while both substitute parts specify 0.028" (0.70mm) for Panasonic and 0.020" (0.50mm) for Susumu. These variations remain within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part should be selected for general industrial applications?

A: Both substitute parts are suitable. Selection depends on specific environmental requirements. For standard industrial use, either part provides improved tolerance and temperature stability. For corrosive environments, the RG3216P-3652-B-T5 anti-sulfur coating offers additional protection.
