RT0805FRE07154RL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07154RL is a 154 Ohms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO, this component is actively produced and ROHS3 compliant. Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, optimize cost structures, and maintain design continuity when the primary part becomes unavailable or when design requirements necessitate enhanced performance characteristics such as improved tolerance or automotive-grade reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07154RL is determined by the following mandatory parameters:

• Resistance Value: Must be 154 Ohms
• Package Type: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Packaging Format: Tape & Reel (TR)

Two substitute parts meet these criteria with variations in tolerance and power rating:

1. ERA-6AEB1540V (Panasonic): Upgrade substitute with improved tolerance (±0.1%) and automotive AEC-Q200 qualification
2. 4-2176091-2 (TE Connectivity): Direct substitute with improved tolerance (±0.1%) and higher power rating (0.25W)

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB1540V is the preferred upgrade substitute when design specifications permit. This part maintains identical power rating and package dimensions while providing superior tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. ROHS3 compliance is maintained. This substitute is suitable for applications requiring enhanced precision and automotive-grade reliability.

4-2176091-2 serves as a direct functional substitute with improved tolerance and higher power dissipation capability (0.25W). However, this part is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement. The increased power rating provides thermal margin in applications approaching the 0.125W limit of the original part.

RT0805FRE07154RL remains the baseline selection for cost-optimized designs where standard tolerance (±1%) and ROHS3 compliance are sufficient.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1540V be used as a direct replacement for RT0805FRE07154RL?

A: Yes. Both parts share identical resistance value (154 Ohms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). ERA-6AEB1540V provides improved tolerance and temperature stability. Physical dimensions and termination count are equivalent.

Q: What is the primary difference between the two substitute parts?

A: ERA-6AEB1540V maintains the original 0.125W power rating with AEC-Q200 automotive qualification and ROHS3 compliance. 4-2176091-2 increases power rating to 0.25W but is RoHS non-compliant. Both offer ±0.1% tolerance improvement over the original ±1%.

Q: Is the height difference between parts significant?

A: Height variations are minimal. RT0805FRE07154RL and ERA-6AEB1540V both measure 0.024" (0.60mm) maximum seated height. 4-2176091-2 measures 0.026" (0.65mm). These differences are within standard PCB assembly tolerances and do not affect interchangeability in standard 0805 footprints.

Q: Which substitute should be selected for automotive applications?

A: ERA-6AEB1540V is the appropriate selection for automotive applications due to AEC-Q200 qualification. This certification confirms compliance with automotive reliability and performance standards.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. RT0805FRE07154RL, ERA-6AEB1540V, and 4-2176091-2 are all supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Q: What is the impact of tolerance differences on circuit performance?

A: The original part specifies ±1% tolerance, resulting in a resistance range of 152.46 to 155.54 Ohms. Both substitute parts offer ±0.1% tolerance, narrowing the range to 153.846 to 154.154 Ohms. This improved tolerance reduces circuit parameter variation and is beneficial in precision analog circuits, filters, and measurement applications.
