Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR010EV is determined by the following critical parameters:

• Resistance Value: Must be 10 mOhms ±1%
• Package / Case: Must be 2512 (6432 Metric) for PCB footprint compatibility
• Tolerance: Must be ±1% for precision current sensing applications
• Composition: Thick film or metal element compositions are acceptable for current sense applications
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

All substitute parts listed maintain these core electrical and mechanical specifications. Power rating may be upgraded from 1W to 2W without functional impact, as higher power ratings provide additional thermal margin. Temperature coefficient and operating temperature range variations are acceptable provided they meet or exceed the original specification requirements.

Engineering Selection Recommendations

CSR2512FK10L0 (Stackpole Electronics Inc): This substitute provides a direct upgrade path with improved temperature coefficient (±200ppm/°C vs ±500ppm/°C) and extended operating temperature range (-55°C ~ 155°C). Power rating is increased to 2W, providing additional thermal headroom. Product status is active with established supply chain availability. Suitable for general industrial and commercial applications requiring current sensing.

CSRN2512FK10L0 (Stackpole Electronics Inc): This variant adds AEC-Q200 automotive qualification to the CSR2512FK10L0 specification. Identical electrical performance with automotive-grade reliability assurance. Recommended for automotive and mission-critical applications where AEC-Q200 compliance is required or preferred. Higher inventory availability (9487 pcs) supports volume production requirements.

PMR100HZPFU10L0 (Rohm Semiconductor): This substitute features metal element composition with superior temperature coefficient performance (±100ppm/°C). Includes AEC-Q200 automotive qualification and reduced height profile (0.019" vs 0.026"). Recommended for precision current sensing applications requiring tighter temperature stability and automotive-grade reliability. Metal element construction provides enhanced frequency response characteristics for high-speed current measurement.

Frequently Asked Questions (FAQ)

Q: Can I use a 2W rated resistor as a direct replacement for the 1W LVC25FR010EV?

A: Yes. The 2W substitute parts maintain identical resistance, tolerance, and package specifications. Higher power rating provides additional thermal margin without affecting electrical performance or PCB footprint compatibility.

Q: What is the difference between thick film and metal element composition for current sensing?

A: Both compositions are acceptable for current sense applications. Metal element (PMR100HZPFU10L0) offers superior temperature coefficient stability (±100ppm/°C vs ±200ppm/°C) and lower height profile. Thick film compositions (CSR2512FK10L0, CSRN2512FK10L0) provide established performance in standard applications.

Q: Are the substitute parts pin-compatible with the original LVC25FR010EV?

A: Yes. All substitute parts use the 2512 (6432 Metric) package with identical two-termination configuration and footprint dimensions within manufacturing tolerance.

Q: Which substitute should I select for automotive applications?

A: CSRN2512FK10L0 or PMR100HZPFU10L0 are both AEC-Q200 qualified. CSRN2512FK10L0 provides thick film performance with automotive certification. PMR100HZPFU10L0 offers metal element composition with superior temperature coefficient for precision automotive current sensing.

Q: What is the impact of different temperature coefficients on circuit performance?

A: Temperature coefficient affects resistance stability across the operating temperature range. PMR100HZPFU10L0 (±100ppm/°C) provides the tightest tolerance tracking. CSR2512FK10L0 and CSRN2512FK10L0 (±200ppm/°C) offer improved stability compared to the original LVC25FR010EV (±500ppm/°C). Selection depends on circuit accuracy requirements.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all parts meet the circuit's electrical and environmental requirements. Mixing thick film and metal element compositions in the same application is acceptable if tolerance and temperature coefficient specifications are satisfied.
