Key Parameters

Substitute Part Grouping Explanation

Substitution of the LVC25JR075EV is determined by the following critical parameters:

• Resistance Value: Must be 75 mOhms
• Package Type: Must be 2512 (6432 Metric) for mechanical and thermal compatibility
• Composition: Thick film construction maintains electrical characteristics
• Application Class: Current sense designation ensures appropriate design specifications
• Temperature Coefficient: ±100ppm/°C maintains performance stability across operating range
• Compliance: ROHS3 compliance required for regulatory alignment

The CRM2512-FX-R075ELF from Bourns Inc. meets all substitution criteria. This part maintains the same resistance value, package footprint, and application class while offering improved tolerance (±1% versus ±5%) and higher power rating (2W versus 1W).

Parameter Comparison

Engineering Selection Recommendations

The CRM2512-FX-R075ELF is the qualified substitute for the obsolete LVC25JR075EV. Selection is based on:

• Identical Resistance and Package: Both parts maintain 75 mOhms in 2512 (6432 Metric) package, ensuring direct PCB compatibility
• Active Product Status: The Bourns component is in active production, providing long-term availability and supply chain stability
• Regulatory Compliance: Both parts are ROHS3 compliant with identical moisture sensitivity ratings
• Enhanced Specifications: The substitute offers tighter tolerance (±1%) and higher power rating (2W), providing design margin without requiring circuit modifications
• Extended Temperature Range: Operating range of -55°C ~ 155°C exceeds the original specification, supporting broader application environments

Frequently Asked Questions (FAQ)

Q: Can the CRM2512-FX-R075ELF be used as a direct replacement for the LVC25JR075EV?

A: Yes. Both parts share identical resistance value, package footprint, and thermal characteristics. The substitute maintains full mechanical and electrical compatibility with existing PCB designs.

Q: What are the differences between these parts?

A: The primary differences are tolerance (±1% versus ±5%), power rating (2W versus 1W), and operating temperature range (-55°C ~ 155°C versus -40°C ~ 125°C). The substitute offers improved specifications without requiring design changes.

Q: Does the higher power rating of the substitute affect circuit performance?

A: No. Higher power rating provides additional thermal margin and does not alter electrical behavior. The component will operate identically in circuits designed for the original 1W part.

Q: Are both parts available in the same packaging format?

A: Both parts use 2512 (6432 Metric) package. The CRM2512-FX-R075ELF is supplied in Tape & Reel (TR) format, standard for production environments.

Q: What is the significance of the ±1% tolerance improvement?

A: Tighter tolerance reduces resistance variation across the production batch, improving current sense circuit accuracy and measurement consistency in applications requiring precise current monitoring.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited). No compliance barriers exist for substitution.
