Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0741R2L is determined by the following critical parameters:

• Resistance value: 41.2 Ohms (exact match required)
• Package format: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Composition: Thin film construction
• Operating temperature range: Must encompass -55°C to 155°C
• RoHS compliance: ROHS3 Compliant

The CPF0402B41R2E1 qualifies as a substitute part because it maintains identical resistance, package, power rating, and operating temperature specifications while meeting all compliance requirements. Enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance upgrades rather than compatibility limitations.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0741R2L and CPF0402B41R2E1 maintain Active product status and full ROHS3 compliance with unlimited moisture sensitivity ratings. The CPF0402B41R2E1 offers tighter tolerance specifications (±0.1% versus ±1%) and superior temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring enhanced precision and thermal stability. Selection between these parts should be based on application-specific accuracy requirements and supply availability rather than functional compatibility, as both components satisfy identical electrical and mechanical interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B41R2E1 directly replace the RT0402FRE0741R2L in existing designs?

A: Yes. Both components share identical resistance values, package formats, power ratings, and operating temperature ranges. The CPF0402B41R2E1 features improved tolerance and temperature coefficient specifications, which represent performance enhancements rather than compatibility issues.

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

A: The primary differences are tolerance (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). The CPF0402B41R2E1 delivers superior precision and thermal stability. All other electrical and mechanical parameters remain identical.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C and maintain ROHS3 compliance throughout this range.

Q: Does the 0402 package format remain consistent between these parts?

A: Yes. Both the RT0402FRE0741R2L and CPF0402B41R2E1 use the 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.014", 0.35mm).

Q: Are moisture sensitivity considerations the same for both parts?

A: Yes. Both components carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage or handling.
