Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE0710R5L are qualified based on the following criteria:

Electrical Parameters (Must Match or Exceed):

• Resistance value: 10.5 Ohms (exact match required)
• Power rating: minimum 0.063W (1/16W)
• Operating temperature range: minimum -55°C ~ 155°C coverage
• Composition: Thin Film construction

Mechanical Parameters (Must Match):

• Package / Case: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height - Seated (Max): 0.014" (0.35mm)
• Number of Terminations: 2

Compliance Parameters (Must Match or Exceed):

Tolerance specifications may be tighter (lower values) than the main part without affecting substitution eligibility, as this represents improved precision capability.

Parameter Comparison

Engineering Selection Recommendations

The CPF0402B10R5E1 (TE Connectivity Passive Product, Neohm series) qualifies as a direct substitute for the RT0402FRE0710R5L based on matching electrical, mechanical, and compliance specifications. Both components are Active products with identical RoHS3 compliance and REACH Unaffected status.

The CPF0402B10R5E1 provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), representing enhanced precision characteristics. These improvements do not create incompatibility; they represent superior performance within the same functional category.

Both parts maintain identical package geometry, thermal characteristics, and environmental ratings, ensuring direct PCB footprint compatibility and equivalent thermal behavior in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B10R5E1 be used as a direct replacement for the RT0402FRE0710R5L?

A: Yes. Both components share identical resistance values (10.5 Ohms), power ratings (0.063W), package dimensions (0402 / 1005 Metric), and operating temperature ranges (-55°C ~ 155°C). Mechanical and electrical compatibility is confirmed.

Q: What is the difference in tolerance between these parts?

A: The RT0402FRE0710R5L carries ±1% tolerance, while the CPF0402B10R5E1 carries ±0.1% tolerance. The tighter tolerance of the substitute part does not affect substitution eligibility and may provide improved circuit performance in precision applications.

Q: Are there differences in temperature stability?
