RT0402FRE0732R4L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0732R4L is a 32.4 Ohm thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package format. This component is rated at 1/16W (0.063W) with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 rating, making it suitable for high-reliability applications requiring stable resistive elements in compact form factors.

Identifying equivalent and substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements call for enhanced performance characteristics such as improved tolerance specifications or lower temperature coefficients.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0402FRE0732R4L is determined by strict adherence to the following critical parameters:

• Resistance Value: Must be exactly 32.4 Ohms
• Package Format: Must be 0402 (1005 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be rated at minimum 0.063W (1/16W)
• Composition: Must be thin film construction
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: Must maintain ROHS3 compliance and MSL Level 1 rating

The CPF0402B32R4E1 qualifies as a direct substitute because it matches all mandatory parameters while offering enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0732R4L and CPF0402B32R4E1 maintain Active product status and full ROHS3 compliance with MSL Level 1 rating. The CPF0402B32R4E1 provides enhanced performance through tighter tolerance specification (±0.1% versus ±1%) and superior temperature coefficient stability (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring greater precision and thermal stability. Both parts are electrically and mechanically interchangeable within the specified operating parameters. Selection between these parts should be based on application-specific tolerance and temperature coefficient requirements, as well as supplier availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B32R4E1 be used as a direct replacement for the RT0402FRE0732R4L?

A: Yes. Both parts share identical resistance value (32.4 Ohms), package format (0402), power rating (1/16W), and operating temperature range (-55°C to 155°C). The CPF0402B32R4E1 offers improved tolerance and temperature coefficient specifications, making it a compatible upgrade.

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

A: The primary differences are tolerance specification (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). The CPF0402B32R4E1 provides superior precision and thermal stability. All other electrical and mechanical parameters remain identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 0402 (1005 Metric) package with matching dimensions (0.039" L x 0.020" W) and maximum seated height (0.014"). PCB footprints and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RT0402FRE0732R4L and CPF0402B32R4E1 are ROHS3 compliant with MSL Level 1 rating and maintain Active product status.

Q: Which part should be selected for high-precision applications?

A: The CPF0402B32R4E1 is the appropriate choice for applications requiring tighter tolerance control and improved temperature coefficient stability due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient specifications.
