RT0402FRE0736R5L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0736R5L is a 36.5 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 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). This resistor is suitable for precision analog circuits, signal conditioning, and general-purpose applications requiring stable resistance values in compact form factors.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate specific application requirements such as enhanced tolerance specifications or alternative compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0736R5L is determined by the following critical parameters:

• Resistance Value: Must be 36.5 Ohms
• Package Format: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Power Rating: Must be 0.063W (1/16W) or higher
• Operating Temperature Range: Must cover or exceed -55°C to 155°C
• Number of Terminations: Must be 2
• Physical Dimensions: Must be compatible with 0402 footprint specifications

The CPF0402B36R5E1 manufactured by TE Connectivity Passive Product meets all substitution criteria. This part maintains identical resistance value, package format, power rating, and operating temperature range. The substitute offers enhanced tolerance specification (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter tolerance control.

Parameter Comparison

Engineering Selection Recommendations

RT0402FRE0736R5L (Primary Part): Select this part for applications requiring ROHS3 compliance. The ±1% tolerance and ±50ppm/°C temperature coefficient are suitable for general-purpose analog circuits and applications where standard tolerance specifications are acceptable.

CPF0402B36R5E1 (Substitute Part): Select this part for applications requiring enhanced tolerance control (±0.1%) and improved temperature stability (±25ppm/°C). This substitute is appropriate for precision measurement circuits, calibration networks, and temperature-sensitive analog applications. Note that this part is RoHS non-compliant; verify compliance requirements before selection for regulated applications or end markets with mandatory RoHS certification.

Both parts share identical package footprints, power ratings, and operating temperature ranges, ensuring direct PCB layout compatibility and thermal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B36R5E1 be used as a direct replacement for RT0402FRE0736R5L on existing PCBs?

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

Q: What is the primary difference between these two parts?

A: The CPF0402B36R5E1 offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The RT0402FRE0736R5L maintains ROHS3 compliance, while the substitute does not.

Q: Which part should be selected for precision analog applications?

A: The CPF0402B36R5E1 is preferred for applications requiring tolerance control better than ±1% or temperature stability better than ±50ppm/°C. Verify RoHS compliance requirements before selection.

Q: Are there any thermal or power dissipation differences between these parts?

A: No. Both parts are rated at 0.063W (1/16W) and operate across -55°C to 155°C. Thermal performance and power handling are equivalent.

Q: What is the MSL rating for both parts?

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