Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR330 is determined by strict equivalence across the following parameters:

• Resistance value: 330 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The RLP73K3AR33FTDF from TE Connectivity Passive Product meets all these criteria and qualifies as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR33FTDF be used as a direct replacement for CSRN2512FTR330?

A: Yes. Both parts share identical resistance, tolerance, power rating, package, composition, temperature coefficient, and operating temperature range. They are electrically and mechanically interchangeable.

Q: Are there any dimensional differences between these parts?

A: The seated height differs slightly. CSRN2512FTR330 has a maximum seated height of 0.028" (0.70mm), while RLP73K3AR33FTDF has a maximum seated height of 0.033" (0.84mm). Both conform to the 2512 package specification. Verify PCB clearance requirements for your application.

Q: Do both parts meet automotive qualification requirements?

A: The CSRN2512FTR330 carries AEC-Q200 qualification. The RLP73K3AR33FTDF does not list AEC-Q200 in the provided specifications. If AEC-Q200 certification is a design requirement, the CSRN2512FTR330 is the specified choice.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: This parameter defines the resistance change per degree Celsius across the operating temperature range. Both parts maintain this specification, ensuring predictable performance in current sensing applications across -55°C to 155°C.

Q: Are these parts suitable for high-frequency applications?

A: These are thick film chip resistors designed for current sensing. Frequency performance is not specified in the provided parameters. Consult detailed datasheets for high-frequency behavior if required.
