RT0402FRE0725R5L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0725R5L is a 25.5 Ohm thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package format. This component is rated at 1/16W (0.063W) with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). This resistor is suitable for precision analog circuits, signal conditioning, and general-purpose applications requiring stable resistance values in compact form factors.

Equivalent and substitute parts are identified when they maintain functional compatibility through matching or exceeding critical electrical and mechanical specifications while maintaining the same package footprint and environmental compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0725R5L is determined by the following critical parameters:

• Resistance Value: Must be 25.5 Ohms (exact match required)
• Package Format: Must be 0402 (1005 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be ≥0.063W (1/16W)
• Composition: Thin film construction for performance consistency
• Operating Temperature Range: Must cover or exceed -55°C to 155°C
• Environmental Compliance: ROHS3 compliance and MSL 1 rating required

The CPF0402B25R5E1 qualifies as a direct substitute based on these parameters. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0725R5L and CPF0402B25R5E1 are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring environmental regulatory adherence. The CPF0402B25R5E1 provides enhanced performance characteristics through tighter tolerance and improved temperature stability, making it the preferred choice for precision-critical applications. The RT0402FRE0725R5L remains appropriate for general-purpose applications where the ±1% tolerance and ±50ppm/°C temperature coefficient meet design requirements. Both components share identical package dimensions, footprint, and thermal operating range, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B25R5E1 be used as a direct replacement for RT0402FRE0725R5L?
