LVC20JR750EV Equivalent & Substitute Parts

Part Overview

The LVC20JR750EV is a 750 mOhms ±5% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) package, manufactured by Ohmite. This component is designed for current sense applications with moisture-resistant construction and operates across -40°C to 125°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility while meeting modern supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value: 750 mOhms (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Features: Current Sense capability (required)
• RoHS3 Compliance (required)
• MSL Rating: 1 (required)

Tolerance and power rating may vary within acceptable engineering limits. Substitute parts meeting these criteria are electrically and mechanically compatible with the original LVC20JR750EV.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and MSL 1 ratings, ensuring long-term availability and environmental regulatory compliance.

RCWE2010R750FKEA offers the highest power rating at 1W with ±1% tolerance and includes Automotive AEC-Q200 qualification, providing enhanced reliability margin and extended operating temperature range (-55°C to 155°C). This part is suitable for applications requiring automotive-grade components or higher thermal headroom.

73L6R75F, RL73H2HR75FTDF, and RL73H2HR75FTE maintain the original 0.75W power rating with ±1% tolerance and extended operating temperature ranges. RL73H2HR75FTE has the highest inventory availability (13,294 pcs), supporting immediate procurement needs. RL73H2HR75FTDF and RL73H2HR75FTE are functionally equivalent TE Connectivity products with identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R750FKEA replace LVC20JR750EV in all applications? A: RCWE2010R750FKEA is electrically and mechanically compatible. The higher 1W power rating provides additional thermal margin. The extended operating temperature range (-55°C to 155°C) exceeds the original specification (-40°C to 125°C). Verify application requirements do not restrict to the original temperature range.

Q: What is the difference between 73L6R75F and the RL73H2 series? A: Both are functionally equivalent 0.75W, ±1% tolerance parts in 2010 package. The primary difference is manufacturer: 73L6R75F is from CTS Resistor Products, while RL73H2HR75FTDF and RL73H2HR75FTE are from TE Connectivity. Electrical and mechanical specifications are identical.

Q: Why do substitute parts have ±1% tolerance instead of ±5%? A: Modern production of 750 mOhms thick film resistors in 2010 package achieves ±1% tolerance as standard. This represents improved manufacturing capability and provides tighter resistance control, which is beneficial for current sense applications.

Q: Are all substitutes available in Tape & Reel packaging? A: All four substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Which substitute has the best supply availability? A: RL73H2HR75FTE has 13,294 pcs in stock, the highest inventory level among all substitutes.
