Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0726R1L is determined by the following criteria:

• Identical resistance value: 26.1 Ohms
• Equal or superior tolerance: ±1% or better
• Equal or superior power rating: 0.063W minimum
• Identical package: 0402 (1005 Metric)
• Identical composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance required
• MSL rating: 1 (Unlimited) or equivalent

The CPF0402B26R1E1 from TE Connectivity Passive Product meets all substitution criteria with superior tolerance specification (±0.1% versus ±1%).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0726R1L and CPF0402B26R1E1 are Active products with full RoHS3 compliance and REACH unaffected status. The CPF0402B26R1E1 provides enhanced performance characteristics through tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring improved stability and precision. Both components are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B26R1E1 directly replace RT0402FRE0726R1L?

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

Q: Are there any package compatibility concerns?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.014", 0.35mm). PCB footprints are interchangeable.

Q: What is the significance of tolerance differences?

A: The CPF0402B26R1E1 maintains ±0.1% tolerance compared to ±1% for the RT0402FRE0726R1L. This tighter tolerance reduces resistance variation across the production batch, beneficial for precision circuits where resistance accuracy is critical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory standards.

Q: What does temperature coefficient indicate?

A: Temperature coefficient (ppm/°C) measures resistance change per degree Celsius. The CPF0402B26R1E1 at ±25ppm/°C exhibits lower drift across temperature variations compared to the RT0402FRE0726R1L at ±50ppm/°C, providing improved stability in temperature-sensitive applications.
