CSRL3-0R02F8 Equivalent & Substitute Parts

Part Overview

The CSRL3-0R02F8 is a 20 mOhms ±1% 3W chip resistor in 2512 (6432 Metric) package manufactured by Riedon. This current sense, non-inductive metal element resistor is designed for precision low-resistance applications requiring high power dissipation. The part is active in production with 5095 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package class and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRL3-0R02F8 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 mOhms ±1%
• Power rating: 3W minimum
• Package class: 2512 (6432 Metric)
• Composition: Metal Element
• Operating temperature range: -55°C to 170°C minimum
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part CRA2512-FZ-R020ELF meets all mandatory electrical and mechanical criteria. Dimensional variations within standard package tolerances and differences in temperature coefficient (±50ppm/°C vs. ±75ppm/°C) do not preclude substitution when the primary application requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRL3-0R02F8 and CRA2512-FZ-R020ELF are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings. The CRA2512-FZ-R020ELF carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The tighter temperature coefficient of the Bourns part (±50ppm/°C) offers improved thermal stability compared to the Riedon specification (±75ppm/°C). Selection between these parts depends on application-specific requirements for automotive qualification and thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Can CRA2512-FZ-R020ELF replace CSRL3-0R02F8 in all applications?

A: Yes, provided the application does not explicitly exclude AEC-Q200 qualified components. Both parts meet identical electrical specifications (20 mOhms ±1%, 3W) and operate across the same temperature range (-55°C to 170°C). Dimensional compatibility is maintained within standard 2512 package tolerances.

Q: What is the significance of the temperature coefficient difference?

A: The CRA2512-FZ-R020ELF has a tighter temperature coefficient (±50ppm/°C) compared to the CSRL3-0R02F8 (±75ppm/°C). This means the Bourns part exhibits smaller resistance variation across the operating temperature range, which may be beneficial in precision current sensing applications where temperature stability is critical.

Q: Are there packaging differences between these parts?

A: The CSRL3-0R02F8 is supplied in Tape & Reel (TR) format, while the CRA2512-FZ-R020ELF is available in Cut Tape (CT) and Digi-Reel® formats. Both use the same 2512 (6432 Metric) package. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet RoHS requirements?

A: Yes, both the CSRL3-0R02F8 and CRA2512-FZ-R020ELF are ROHS3 compliant with MSL 1 (Unlimited) ratings, making them suitable for applications with RoHS compliance requirements.

Q: What does AEC-Q200 qualification mean for the Bourns part?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. The CRA2512-FZ-R020ELF meets this standard, making it suitable for automotive applications where such qualification is specified or preferred.
