RT0805FRE0738K3L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0738K3L is a 38.3 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.125W (1/8W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and active product status. Substitute parts are identified when equivalent resistance values, package dimensions, and electrical performance parameters align within acceptable tolerances for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0738K3L is determined by the following mandatory parameters:

• Resistance Value: Must be 38.3 kOhms
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Number of Terminations: Must be 2
• Physical Dimensions: Length 0.079" (2.00mm), Width 0.049" (1.25mm)

Substitute parts identified in this reference meet all mandatory parameters. Tolerance and power rating variations are noted as they may affect circuit performance in precision or high-dissipation applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes should be based on the following considerations:

RT0805BRD0738K3L (YAGEO): Offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. Same manufacturer as primary part.

5-2176093-7 (TE Connectivity): Provides higher power rating (0.25W vs 0.125W) with improved tolerance and temperature coefficient. Suitable for applications requiring additional thermal margin.

ERA-6AEB3832V (Panasonic): Includes AEC-Q200 automotive qualification with improved tolerance and temperature coefficient. Appropriate for automotive or high-reliability applications.

RG2012P-3832-B-T5 (Susumu): Combines AEC-Q200 automotive qualification with anti-sulfur feature, improved tolerance, and temperature coefficient. Lowest seated height (0.020" vs 0.024") among substitutes.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0738K3L replace RT0805FRE0738K3L directly? A: Yes. Both parts share identical resistance value, power rating, package dimensions, and operating temperature range. The substitute offers superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade.

Q: What is the difference between 0.125W and 0.25W power ratings? A: Power rating indicates maximum continuous power dissipation. The 0.25W variant (5-2176093-7) can safely dissipate twice the power of the 0.125W variants. Selection depends on circuit current and resistor voltage drop requirements.

Q: Are automotive-qualified parts (ERA-6AEB3832V, RG2012P-3832-B-T5) interchangeable with standard industrial parts? A: Yes, automotive-qualified parts meet or exceed industrial specifications. AEC-Q200 certification indicates additional qualification testing. These parts are suitable for any application requiring the specified electrical parameters.

Q: Does package dimension variation affect PCB layout? A: All substitutes maintain 0805 (2012 Metric) package with 0.079" length and 0.049" width. Seated height varies slightly (0.020" to 0.026"), which is negligible for standard PCB assembly processes.

Q: What does MSL 1 rating mean? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating.
