LVC25JR910EV Equivalent & Substitute Parts

Part Overview

The LVC25JR910EV is a 910 mOhms ±5% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This thick film current sense resistor features moisture resistance and operates across -40°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC25JR910EV is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 910 mOhms (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)

Allowable Variations:

• Tolerance: May improve from ±5% to ±1% (tighter tolerance is acceptable)
• Power Rating: May increase from 1W to 2W (higher rating is acceptable)
• Operating Temperature Range: May expand beyond -40°C ~ 125°C (wider range is acceptable)
• RoHS Status: May vary based on application requirements
• Certifications: Additional certifications (AEC-Q200) are acceptable

Three active substitute parts meet these criteria with improvements in tolerance and/or power rating while maintaining identical resistance, package, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

RCWE2512R910FKEA (Vishay Dale) is the primary upgrade option. This part provides improved tolerance (±1% vs ±5%), increased power rating (2W vs 1W), expanded operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, and ROHS3 compliance. It is suitable for applications requiring enhanced performance margins and automotive-grade reliability.

RL73H3AR91FTE (TE Connectivity) is the recommended alternative for applications requiring ROHS3 compliance and active product status. This part maintains the original 1W power rating and operating temperature range while providing ±1% tolerance and expanded temperature capability (-55°C ~ 155°C). It is suitable for general industrial and consumer applications.

RL73H3AR91FTDF (TE Connectivity) is functionally equivalent to RL73H3AR91FTE but carries RoHS non-compliant status. Selection of this part requires confirmation that RoHS compliance is not a regulatory requirement for the application.

Frequently Asked Questions (FAQ)

Q: Can RCWE2512R910FKEA replace LVC25JR910EV in all applications? A: RCWE2512R910FKEA is electrically and mechanically compatible. The improved tolerance (±1%) and increased power rating (2W) provide enhanced performance margins. Verify that the 2W rating does not create thermal management conflicts in the PCB layout.

Q: What is the difference between RL73H3AR91FTDF and RL73H3AR91FTE? A: Both parts are functionally identical in electrical and mechanical specifications. The primary difference is RoHS compliance status: RL73H3AR91FTE is ROHS3 compliant, while RL73H3AR91FTDF is RoHS non-compliant. Select based on regulatory requirements.

Q: Are all substitute parts in the same 2512 package? A: Yes. All substitute parts use the 2512 (6432 Metric) package with identical footprints and mounting requirements. Dimensional variations are within standard manufacturing tolerances.

Q: Does tolerance improvement from ±5% to ±1% affect circuit design? A: Tighter tolerance improves circuit accuracy and reduces design margin requirements. No circuit redesign is necessary; the ±1% tolerance is a direct improvement over the original ±5% specification.

Q: Can these parts be used in high-temperature applications? A: All substitute parts operate to 155°C maximum, exceeding the original -40°C ~ 125°C range. Verify that component derating curves and PCB material specifications support the extended temperature range.

Q: What is the significance of AEC-Q200 certification on RCWE2512R910FKEA? A: AEC-Q200 certification indicates automotive-grade reliability testing and qualification. This certification is required for automotive applications but is optional for general industrial use.
