Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0735R7L is determined by the following critical parameters:

• Resistance Value: Must be 35.7 Ohms
• Package Format: Must be 0402 (1005 Metric) with identical physical dimensions (0.039" L x 0.020" W, Height 0.014" max)
• Power Rating: Must support minimum 0.063W (1/16W)
• Composition: Thin film construction required
• Operating Temperature Range: Must cover -55°C to 155°C minimum
• Compliance: ROHS3 compliance required

The CPF0402B35R7E1 from TE Connectivity Passive Product qualifies as a direct substitute, meeting all mandatory electrical and mechanical parameters while offering enhanced tolerance specification (±0.1% versus ±1%) and improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0735R7L and CPF0402B35R7E1 maintain Active product status and satisfy ROHS3 compliance requirements. Selection between these components should be based on application-specific tolerance and temperature stability requirements.

The RT0402FRE0735R7L is appropriate for general-purpose applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit specifications.

The CPF0402B35R7E1 provides enhanced precision with ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for applications requiring tighter resistive accuracy and improved thermal stability. Both components are electrically and mechanically interchangeable within the specified parameter constraints.
