Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR025EV is determined by the following critical parameters:

• Resistance value: 25 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense capability (required)

The substitute parts CSR2512FK25L0 and CSRN2512FK25L0 meet all mandatory electrical and mechanical compatibility criteria. Both are active products from Stackpole Electronics Inc with identical resistance, tolerance, and package specifications. The primary differences are power rating (2W vs. 1W) and temperature coefficient performance, which represent improvements over the obsolete LVC25FR025EV.

Parameter Comparison

Engineering Selection Recommendations

Both CSR2512FK25L0 and CSRN2512FK25L0 are direct functional equivalents to the LVC25FR025EV. Selection between them depends on application requirements:

CSR2512FK25L0 is suitable for general current sense applications where standard industrial specifications are sufficient. This part maintains active production status and full RoHS3 compliance.

CSRN2512FK25L0 is the preferred selection for automotive applications or designs requiring extended temperature performance. This part carries AEC-Q200 qualification, indicating compliance with automotive reliability standards. The improved temperature coefficient (±200ppm/°C vs. ±350ppm/°C) and extended operating range (-55°C ~ 155°C vs. -40°C ~ 125°C) provide superior performance stability across wider environmental conditions.

Both substitute parts offer 2W power rating, providing thermal margin beyond the original 1W specification. All parts maintain identical package geometry and electrical characteristics necessary for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FK25L0 or CSRN2512FK25L0 be used as direct replacements for LVC25FR025EV on existing PCBs?

A: Yes. Both substitute parts are mechanically and electrically compatible. The 2512 (6432 Metric) package dimensions are equivalent, and the 25 mOhms ±1% resistance specification matches exactly. No PCB layout modifications are required.

Q: What is the difference between CSR2512FK25L0 and CSRN2512FK25L0?

A: Both parts share identical electrical specifications (25 mOhms, ±1%, 2W, 2512 package). The CSRN2512FK25L0 includes AEC-Q200 automotive qualification and is recommended for automotive applications. The CSR2512FK25L0 is suitable for general industrial use.

Q: Why do the substitute parts have a higher power rating (2W vs. 1W)?

A: The 2W rating represents an improvement in thermal capability. This does not affect circuit operation but provides additional thermal margin and reliability. The parts remain suitable for applications originally designed for 1W components.

Q: Are there any compliance differences between the three parts?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The CSRN2512FK25L0 additionally carries AEC-Q200 automotive qualification. All parts use EAR99 ECCN classification.

Q: What is the temperature coefficient significance?

A: The substitute parts feature ±200ppm/°C temperature coefficient compared to ±350ppm/°C for the original LVC25FR025EV. This represents improved resistance stability across temperature variations, beneficial for precision current sensing applications.
