Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0402FRE0724R3L is based on the following critical parameters that must remain constant or improve:

• Resistance value: 24.3 Ohms (exact match required)
• Package / Case: 0402 (1005 Metric) (physical and electrical compatibility)
• Power rating: 0.063W minimum (1/16W)
• Composition: Thin Film (electrical characteristics)
• Operating temperature range: -55°C ~ 155°C minimum (environmental compatibility)
• Number of terminations: 2 (circuit interface requirement)

The substitute part CPF0402B24R3E1 meets all these critical parameters. Additionally, it offers improved tolerance (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade option.

Parameter Comparison

Engineering Selection Recommendations

The CPF0402B24R3E1 is electrically and mechanically compatible with the RT0402FRE0724R3L. Both components share identical resistance values, package dimensions, power ratings, and operating temperature ranges. The substitute part provides enhanced tolerance specifications (±0.1% versus ±1%) and improved temperature stability (±25ppm/°C versus ±50ppm/°C).

Selection between these parts should consider compliance requirements. The RT0402FRE0724R3L maintains ROHS3 compliance, while the CPF0402B24R3E1 is RoHS non-compliant. Applications requiring RoHS certification must use the YAGEO part. For applications where RoHS compliance is not mandated, the TE Connectivity part offers superior precision characteristics.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B24R3E1 be used as a direct replacement for RT0402FRE0724R3L?

A: Yes, from an electrical and mechanical standpoint. Both components have identical 24.3 Ohm resistance, 0402 package dimensions, 0.063W power rating, and -55°C to 155°C operating range. However, verify RoHS compliance requirements for your application before substitution.

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

A: The primary differences are tolerance (±0.1% versus ±1%), temperature coefficient (±25ppm/°C versus ±50ppm/°C), and RoHS compliance status. The CPF0402B24R3E1 offers tighter tolerance and better temperature stability but is RoHS non-compliant.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0402 (1005 Metric) package with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.014" (0.35mm). They are mechanically interchangeable on PCBs designed for 0402 components.

Q: Which part should I select for precision-critical applications?

A: The CPF0402B24R3E1 is suitable for applications requiring tighter tolerance control due to its ±0.1% tolerance specification compared to ±1% for the RT0402FRE0724R3L.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the RT0402FRE0724R3L and CPF0402B24R3E1 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
