RT0805FRE07402RL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07402RL is a 402 Ohms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO and classified as Active product status, this component is widely used in precision analog circuits, signal conditioning, and general-purpose resistive networks requiring moderate tolerance specifications.

Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings are maintained while offering improved tolerance grades, enhanced temperature coefficients, or specialized certifications such as automotive qualification (AEC-Q200) or anti-sulfur properties.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07402RL is determined by the following mandatory parameters:

• Resistance Value: Must be 402 Ohms
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status
• Moisture Sensitivity: Must be MSL 1 or equivalent

Substitute parts are grouped into three categories:

Upgrade Substitutes (Improved Tolerance): Parts with tolerance grades tighter than ±1% (±0.5% or ±0.1%) while maintaining identical package, composition, and temperature specifications. These parts are direct functional upgrades suitable for applications requiring higher precision.

Direct Substitutes (Equivalent Specifications): Parts with matching tolerance (±1%) and all core electrical parameters, differing only in manufacturer or minor physical characteristics such as seated height.

Enhanced Substitutes (Specialized Certifications): Parts meeting all core parameters while adding automotive qualification (AEC-Q200) or anti-sulfur properties for specialized application environments.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RT0805DRE07402RL (YAGEO, ±0.5%) provides improved tolerance over the original specification while maintaining identical power rating and temperature range. Product status is Active with 4086 units in stock.

For Precision Analog Circuits: RT0805BRD07402RL (YAGEO, ±0.1%) or ERA-6AEB4020V (Panasonic, ±0.1%) deliver tighter tolerance and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Both are Active status products. ERA-6AEB4020V includes AEC-Q200 automotive qualification if required by application environment.

For Automotive or Harsh Environments: RG2012P-4020-B-T5 (Susumu, ±0.1%) combines AEC-Q200 automotive qualification with anti-sulfur properties. Maintains 0.125W power rating and -55°C ~ 155°C operating range. Product status is Active with 5684 units available.

For Higher Power Dissipation Requirements: 8-2176091-0 (TE Connectivity, ±0.1%) is rated at 0.25W (1/4W), providing double the power handling capacity while maintaining 402 Ohms resistance and ±0.1% tolerance. Suitable when thermal margin is critical.

All substitute parts maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and 0805 (2012 Metric) package compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE07402RL replace RT0805FRE07402RL in my circuit?

A: Yes. Both parts share identical resistance (402 Ω), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RT0805DRE07402RL offers improved tolerance (±0.5% vs. ±1%), making it a direct upgrade suitable for any application using the original part.

Q: What is the difference between ±1%, ±0.5%, and ±0.1% tolerance?

A: Tolerance specifies the maximum deviation from the nominal resistance value. At 402 Ω: ±1% allows ±4.02 Ω deviation, ±0.5% allows ±2.01 Ω deviation, and ±0.1% allows ±0.402 Ω deviation. Tighter tolerance is required for precision analog circuits, signal conditioning, and measurement applications.

Q: Why does 8-2176091-0 have 0.25W power rating instead of 0.125W?

A: 8-2176091-0 is manufactured by TE Connectivity with enhanced power dissipation capability. The 0.25W rating provides additional thermal margin in applications with higher current flow. It remains compatible with 0805 package footprints and maintains all other electrical parameters.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard ensuring the component meets reliability and performance requirements for automotive applications. ERA-6AEB4020V and RG2012P-4020-B-T5 carry this certification. Use these parts when automotive-grade reliability is specified.

Q: Are anti-sulfur properties important for my application?

A: Anti-sulfur properties (featured in RG2012P-4020-B-T5 and RG2012P-4020-D-T5) protect against sulfur-induced corrosion in high-sulfur environments such as industrial or marine settings. Standard parts like RT0805FRE07402RL are suitable for controlled indoor environments.

Q: Can I use a ±0.1% part where ±1% is specified?

A: Yes. A tighter tolerance part is always compatible with applications specifying looser tolerance. The component will perform within the original specification while providing superior accuracy.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All listed substitutes use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Seated height varies slightly (0.020" to 0.026"), but this does not affect PCB assembly compatibility.
