Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0715R8L is determined by the following critical parameters:

• Resistance value: Must be 15.8 Ohms
• Package type: Must be 0402 (1005 Metric)
• Composition: Must be thin film
• Power rating: Must be 0.063W (1/16W) or higher
• Operating temperature range: Must cover -55°C ~ 155°C minimum
• RoHS compliance: Must maintain ROHS3 Compliant status

The CPF0402B15R8E1 qualifies as a direct substitute because it matches all critical parameters while offering enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0715R8L and CPF0402B15R8E1 are active products with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The CPF0402B15R8E1 provides superior performance characteristics with tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it the preferred choice for applications requiring enhanced precision and thermal stability. Selection between these parts should be based on application tolerance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B15R8E1 be used as a direct replacement for RT0402FRE0715R8L?

A: Yes. Both components share identical resistance value, package type, power rating, and operating temperature range. The substitute offers improved tolerance and temperature coefficient specifications.

Q: Are there any physical compatibility concerns?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W) and maximum seated height (0.014"), ensuring mechanical compatibility in PCB layouts.

Q: What is the tolerance difference impact?

A: The RT0402FRE0715R8L has ±1% tolerance, while CPF0402B15R8E1 has ±0.1% tolerance. For a 15.8 Ohm resistor, this represents a maximum deviation of ±0.158 Ohms versus ±0.0158 Ohms respectively. Applications requiring tighter resistance accuracy should use the substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for standard manufacturing and storage conditions.

Q: What is the temperature coefficient difference?

A: The RT0402FRE0715R8L has ±50ppm/°C while CPF0402B15R8E1 has ±25ppm/°C. The substitute exhibits half the temperature-induced resistance drift, beneficial for temperature-sensitive applications.
