Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0715RL is determined by the following critical parameters:

• Resistance Value: Must be 15 Ohms (exact match required)
• Package Type: Must be 0402 (1005 Metric) for PCB footprint compatibility
• Power Rating: Must be ≥0.063W (1/16W)
• Composition: Thin film technology for performance consistency
• Operating Temperature Range: Must cover -55°C to 155°C minimum
• Compliance: ROHS3 and REACH requirements must be maintained

The CPF0402B15RE1 qualifies as a direct substitute because it matches all critical parameters while offering improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring enhanced precision.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0715RL and CPF0402B15RE1 are active production components with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for commercial and industrial applications.

The RT0402FRE0715RL is the primary choice for cost-optimized designs where ±1% tolerance is acceptable. The CPF0402B15RE1 is the appropriate selection for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C), such as precision measurement circuits, calibrated signal paths, or temperature-compensated networks. Both components share identical physical dimensions, thermal operating range, and moisture sensitivity classification, ensuring direct PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B15RE1 be used as a direct replacement for RT0402FRE0715RL?

A: Yes. Both components are 15 Ohm thin film resistors in 0402 package with identical physical dimensions, power ratings, and operating temperature ranges. The CPF0402B15RE1 offers superior tolerance and temperature coefficient specifications, making it a compatible upgrade.

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

A: The primary differences are tolerance (±1% vs ±0.1%) and temperature coefficient (±50ppm/°C vs ±25ppm/°C). The CPF0402B15RE1 provides enhanced precision and stability. All other electrical and mechanical parameters are equivalent.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both components have identical 0402 package dimensions (1.00mm x 0.50mm) and maximum seated height (0.35mm), requiring no footprint or layout modifications.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the RT0402FRE0715RL and CPF0402B15RE1 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for commercial and industrial applications.

Q: Which part should be selected for temperature-sensitive applications?

A: The CPF0402B15RE1 is recommended for applications operating across the full -55°C to 155°C range or where temperature-induced resistance drift must be minimized, due to its lower temperature coefficient of ±25ppm/°C.
