RT0805FRE0727R4L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0727R4L is a 27.4 Ohm ±1% thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring 27.4 Ohm resistive elements in compact surface-mount configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0727R4L is determined by the following critical parameters:

• Resistance Value: Must be 27.4 Ohms
• Package Format: Must be 0805 (2012 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity: MSL 1 rating ensures handling compatibility

The identified substitute part 6-1625868-9 (TE Connectivity Passive Product) meets all mandatory substitution criteria. While this substitute offers enhanced tolerance (±0.1% versus ±1%) and increased power rating (0.25W versus 0.125W), these represent performance improvements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0727R4L and 6-1625868-9 maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts should be based on application-specific requirements:

The RT0805FRE0727R4L (YAGEO) is suitable for standard applications where the specified ±1% tolerance and 0.125W power rating meet circuit requirements.

The 6-1625868-9 (TE Connectivity) is appropriate for applications requiring enhanced tolerance control (±0.1%), improved temperature stability (±25ppm/°C versus ±50ppm/°C), or higher power dissipation margins (0.25W versus 0.125W). The identical package footprint and operating temperature range ensure direct PCB compatibility without layout modifications.

Both parts are suitable for high-reliability applications given their MSL 1 rating and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 6-1625868-9 be used as a direct replacement for the RT0805FRE0727R4L?

A: Yes. Both parts share identical resistance values (27.4 Ohms), package format (0805), physical dimensions, operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3). The substitute offers improved tolerance and power rating, making it functionally compatible for direct PCB substitution without layout changes.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance specification (±0.1% versus ±1%), power rating (0.25W versus 0.125W), and temperature coefficient (±25ppm/°C versus ±50ppm/°C). These represent performance enhancements in the substitute part rather than incompatibilities.

Q: Are there any package or footprint considerations?

A: No. Both parts use the identical 0805 (2012 Metric) package with matching physical dimensions (0.079" L x 0.049" W). No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RT0805FRE0727R4L and 6-1625868-9 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They are suitable for equivalent regulatory and environmental applications.

Q: Which part should be selected for high-precision applications?

A: The 6-1625868-9 offers tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it more suitable for applications requiring enhanced accuracy and thermal stability.
