Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC25JR750EV is determined by the following mandatory parameters:

• Resistance Value: 750 mOhms (exact match required)
• Package / Case: 2512 (6432 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental reliability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitute parts may vary in tolerance (±1% or ±5%), power rating (1W or 2W), and operating temperature range, provided the core parameters remain consistent. All identified substitutes maintain the 2512 package footprint and thick film construction, ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and MSL 1 rating, providing long-term supply chain viability compared to the obsolete LVC25JR750EV.

RCWE2512R750FKEA (Vishay Dale): This 2W, ±1% substitute offers enhanced power dissipation capability and tighter tolerance. The inclusion of Automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications. Extended operating temperature range (-55°C ~ 155°C) accommodates broader environmental conditions.

CRM2512-JX-R750ELF (Bourns Inc.): This 2W, ±5% substitute maintains tolerance consistency with the original part while providing increased power rating. Active product status ensures continued availability. Operating temperature range extends to -55°C ~ 155°C.

RL73H3AR75FTDF and RL73H3AR75FTE (TE Connectivity): Both TE Connectivity parts are 1W, ±1% substitutes that preserve the original power rating while offering improved tolerance. RL73H3AR75FTE demonstrates significantly higher inventory availability (39,195 pcs). Both maintain the same operating temperature range extension and current sense functionality.

Frequently Asked Questions (FAQ)

Q: Can RCWE2512R750FKEA replace LVC25JR750EV in all applications?

A: RCWE2512R750FKEA is electrically and mechanically compatible. The 2W power rating is a superset of the 1W requirement, and ±1% tolerance is tighter than ±5%. Automotive AEC-Q200 qualification adds reliability. Extended temperature range (-55°C ~ 155°C) exceeds the original specification (-40°C ~ 125°C). Substitution is valid for applications within the original temperature range.

Q: What is the difference between the two TE Connectivity options?

A: RL73H3AR75FTDF and RL73H3AR75FTE are functionally identical 750 mOhms ±1% 1W thick film resistors in 2512 package. The primary distinction is inventory availability: RL73H3AR75FTE has 39,195 pcs in stock versus 5,965 pcs for RL73H3AR75FTDF. Both are active products with identical electrical and mechanical specifications.

Q: Does increased power rating affect circuit performance?

A: CRM2512-JX-R750ELF and RCWE2512R750FKEA both provide 2W rating versus the original 1W. Higher power rating indicates greater thermal capacity but does not alter electrical behavior at equivalent current levels. These parts are suitable for applications requiring the original 1W specification.

Q: Are all substitutes suitable for current sense applications?

A: All identified substitutes explicitly include current sense functionality. RCWE2512R750FKEA additionally specifies moisture resistance, matching the original part's environmental protection characteristics.

Q: What packaging format is available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The 2512 (6432 Metric) package footprint is consistent across all options.
