Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0734RL is determined by the following critical parameters:

• Resistance Value: Must be 34 Ohms
• Package Type: Must be 0402 (1005 Metric) for mechanical and electrical compatibility
• Power Rating: Must be ≥0.063W (1/16W)
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: ROHS3 and REACH compliance required for equivalent status

The CPF0402B34RE1 qualifies as a direct substitute based on matching all critical parameters while offering improved tolerance (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0734RL and CPF0402B34RE1 are active products with full ROHS3 and REACH compliance. Selection between these components should be based on application-specific tolerance and stability requirements:

The RT0402FRE0734RL is suitable for general-purpose applications where ±1% tolerance and ±50ppm/°C temperature coefficient meet circuit specifications.

The CPF0402B34RE1 provides enhanced precision with ±0.1% tolerance and ±25ppm/°C temperature coefficient, appropriate for precision analog circuits, measurement instrumentation, or applications with stringent tolerance budgets.

Both components share identical mechanical dimensions, power ratings, and thermal operating ranges, ensuring direct PCB layout compatibility and thermal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B34RE1 replace RT0402FRE0734RL in existing designs?

A: Yes. Both components are 0402 (1005 Metric) thin film resistors with identical physical dimensions, power ratings, and operating temperature ranges. The CPF0402B34RE1 offers tighter tolerance and improved temperature stability, making it a direct mechanical and electrical substitute.

Q: What are the tolerance differences between these parts?

A: The RT0402FRE0734RL has ±1% tolerance, while the CPF0402B34RE1 has ±0.1% tolerance. The CPF0402B34RE1 provides ten times tighter tolerance control, beneficial for precision applications but not required for general-purpose circuits.

Q: Are there package compatibility concerns?

A: No. Both components use the 0402 (1005 Metric) package with identical footprints (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.014", 0.35mm). PCB layouts and pick-and-place programming require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RT0402FRE0734RL and CPF0402B34RE1 are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). They meet identical regulatory and environmental requirements.

Q: What is the temperature coefficient difference?

A: The RT0402FRE0734RL has ±50ppm/°C temperature coefficient, while the CPF0402B34RE1 has ±25ppm/°C. The CPF0402B34RE1 exhibits half the resistance change over temperature, providing superior stability in applications with wide thermal operating ranges.
