Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0402FRE0715R4L is determined by strict adherence to the following critical parameters:

• Resistance Value: Must be exactly 15.4 Ohms
• Package Type: Must be 0402 (1005 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.063W (1/16W) or higher
• Composition: Thin film construction for stability and performance consistency
• Operating Temperature Range: Must cover -55°C ~ 155°C minimum
• Compliance: RoHS3 compliance required for regulatory alignment

The CPF0402B15R4E1 qualifies as a direct substitute because it maintains identical resistance, package, power rating, and operating temperature range while offering improved tolerance (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C). These enhancements represent performance upgrades without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0715R4L and CPF0402B15R4E1 are active products with full RoHS3 compliance and unlimited moisture sensitivity rating, making them suitable for production environments. The CPF0402B15R4E1 represents an upgrade path offering tighter tolerance control (±0.1% versus ±1%) and improved temperature stability (±25ppm/°C versus ±50ppm/°C) while maintaining identical mechanical and thermal specifications. Selection between these parts should be based on application tolerance requirements and supply availability rather than functional compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B15R4E1 be used as a direct replacement for RT0402FRE0715R4L?

A: Yes. Both components share identical resistance value, package type, power rating, and operating temperature range. The CPF0402B15R4E1 offers superior tolerance and temperature coefficient performance without introducing any compatibility issues.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both components use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W) and maximum seated height (0.014"). PCB footprints are interchangeable.

Q: What is the significance of the tolerance difference?

A: The RT0402FRE0715R4L maintains ±1% tolerance, while the CPF0402B15R4E1 maintains ±0.1% tolerance. This means the CPF0402B15R4E1 will deliver resistance values closer to the nominal 15.4 Ohms specification, beneficial for precision analog circuits and measurement applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage conditions.

Q: What is the temperature coefficient impact?

A: The RT0402FRE0715R4L exhibits ±50ppm/°C temperature coefficient, while the CPF0402B15R4E1 exhibits ±25ppm/°C. Lower temperature coefficient means resistance value remains more stable across the -55°C ~ 155°C operating range, important for temperature-sensitive applications.
