Key Parameters

Substitute Part Grouping Explanation

Substitution of the LVC25FR015EV is determined by the following critical parameters:

• Resistance Value: 15 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense capability (required)
• RoHS Compliance: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

The substitute parts CSR2512FK15L0 and CSRN2512FK15L0 meet all critical substitution criteria. Both are active products with identical resistance, tolerance, package, and composition specifications. The primary differences are power rating (2W vs. 1W) and temperature coefficient performance, which represent improvements over the original part.

Parameter Comparison

Engineering Selection Recommendations

CSR2512FK15L0 is suitable for general-purpose current sense applications requiring active product status and improved thermal performance. This part offers 2W power rating and extended operating temperature range (-55°C ~ 155°C) compared to the original 1W, 1W rating with narrower temperature range. The part is actively manufactured and maintains full ROHS3 compliance.

CSRN2512FK15L0 is the preferred selection for applications requiring automotive-grade reliability. This part carries AEC-Q200 qualification, indicating compliance with automotive industry standards for component reliability and performance. It provides identical electrical specifications to CSR2512FK15L0 with the addition of automotive certification. Inventory availability is significantly higher (118,469 pcs) compared to CSR2512FK15L0 (695 pcs), supporting production continuity and supply chain stability.

Both substitute parts are direct functional replacements for the obsolete LVC25FR015EV, with enhanced performance characteristics and active manufacturing status ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FK15L0 or CSRN2512FK15L0 be used as direct replacements for LVC25FR015EV?

A: Yes. Both parts meet all critical substitution parameters: identical 15 mOhms resistance, ±1% tolerance, 2512 package, thick film composition, current sense capability, ROHS3 compliance, and MSL 1 rating. The 2W power rating of the substitutes exceeds the original 1W specification, providing improved thermal margin.

Q: What is the difference between CSR2512FK15L0 and CSRN2512FK15L0?

A: Both parts share identical electrical specifications (15 mOhms, ±1%, 2W, ±200ppm/°C). The primary distinction is that CSRN2512FK15L0 carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring industry-standard reliability certification. CSRN2512FK15L0 also has significantly higher inventory availability.

Q: Are there any package or footprint differences between the original and substitute parts?

A: All three parts use the 2512 (6432 Metric) package. Dimensional variations are minimal: LVC25FR015EV measures 0.250" L x 0.130" W with 0.026" max height; CSR2512FK15L0 measures 0.252" L x 0.126" W with 0.026" max height; CSRN2512FK15L0 measures 0.250" L x 0.124" W with 0.028" max height. These variations are within standard PCB design tolerances and do not affect board-level compatibility.

Q: What is the temperature coefficient difference, and does it matter?

A: The original LVC25FR015EV has ±500ppm/°C temperature coefficient, while both substitutes have ±200ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations, representing an improvement in precision and performance for current sense applications.

Q: Which substitute part should be selected for new designs?

A: CSRN2512FK15L0 is recommended for new designs due to active product status, AEC-Q200 automotive qualification, superior inventory availability, and improved performance characteristics. CSR2512FK15L0 is suitable for non-automotive applications where automotive certification is not required.
