LVC06JR100EV Equivalent & Substitute Parts

Part Overview

The LVC06JR100EV is a 100 mOhms ±5% 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Ohmite. This current sense resistor is designed for applications requiring low-value precision resistance with moisture resistance. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain the same resistance value, tolerance, power rating, and package configuration while meeting electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the LVC06JR100EV is determined by the following critical parameters:

Primary Substitution Criteria:

Resistance value: 100 mOhms (mandatory match)
Tolerance: ±5% (acceptable match)
Power rating: 0.5W minimum (equal or higher acceptable)
Package: 1206 (3216 Metric) (mandatory match)
Composition: Thick Film (mandatory match)
Features: Current Sense capability (mandatory)

Secondary Compatibility Factors:

Operating temperature range: Must encompass or exceed -40°C ~ 125°C
RoHS compliance: ROHS3 Compliant (mandatory)
MSL rating: 1 (Unlimited) preferred
Moisture resistance: Required for equivalent substitution

Substitute parts are grouped into two categories:

Direct Substitutes (Same Specifications): Parts matching all primary criteria with identical or superior electrical characteristics.

Upgrade Substitutes (Enhanced Specifications): Parts with improved tolerance (±1% vs ±5%), higher power ratings (0.5W), or extended temperature ranges that provide superior performance while maintaining backward compatibility.

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Discontinuation):

RLP73K2BR10JTD (TE Connectivity) provides the closest electrical match to LVC06JR100EV with identical resistance, tolerance, and power rating. This part maintains ±200ppm/°C temperature coefficient and extends operating temperature range to -55°C ~ 155°C. Active product status ensures long-term availability.

CSR1206JTR100 (Stackpole Electronics) offers equivalent specifications with improved temperature coefficient (±100ppm/°C) and extended temperature range. High inventory availability (825 pcs) supports immediate deployment.

For Enhanced Performance Requirements:

RLP73K2BR10FTDF (TE Connectivity) upgrades tolerance to ±1% while maintaining 0.5W power rating and identical package. Extended temperature range (-55°C ~ 155°C) provides operational margin.

CSR1206FKR100 (Stackpole Electronics) combines ±1% tolerance with superior temperature coefficient (±100ppm/°C) and 0.5W power rating. Extensive inventory (581,040 pcs) ensures supply chain stability.

UCR18EVHJLR10 (Rohm Semiconductor) provides AEC-Q200 automotive qualification with ±5% tolerance and 0.5W rating. Suitable for automotive applications requiring current sense functionality.

For Lower Power Applications:

73L4R10J (CTS Resistor Products) and PT1206FR-070R1L (YAGEO) operate at 0.25W power rating. These parts are suitable only if circuit design permits reduced power dissipation. PT1206FR-070R1L includes AEC-Q200 automotive qualification and moisture resistance.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.25W rated substitute in place of the 0.5W LVC06JR100EV?

A: Only if your circuit design confirms that the resistor will not dissipate more than 0.25W. The 73L4R10J and PT1206FR-070R1L are rated for 0.25W maximum. Exceeding this rating will cause component failure. Verify power dissipation calculations before substitution.

Q: What is the difference between ±5% and ±1% tolerance substitutes?

A: Tolerance defines the acceptable resistance variation from the nominal 100 mOhm value. ±5% allows 95-105 mOhms; ±1% allows 99-101 mOhms. Applications requiring tighter current sensing accuracy benefit from ±1% tolerance parts (RLP73K2BR10FTDF, CSR1206FKR100, PT1206FR-070R1L, UCR18EVHFLR100).

Q: Are all substitute parts in the same 1206 package?

A: Yes. All listed substitutes use the 1206 (3216 Metric) package with identical footprint dimensions (0.120-0.126" L × 0.061-0.063" W). Physical board layout compatibility is maintained across all substitutes.

Q: Which substitute has the best temperature stability?

A: CSR1206FKR100 and UCR18EVHFLR100 offer the lowest temperature coefficients (±100ppm/°C and 0/+150ppm/°C respectively) compared to the original ±200ppm/°C specification. These parts provide superior performance across the extended operating temperature range.

Q: Do all substitutes support automotive applications?

A: PT1206FR-070R1L, UCR18EVHFLR100, and UCR18EVHJLR10 carry AEC-Q200 automotive qualification. Other substitutes are industrial-grade components suitable for non-automotive applications.

Q: What is the inventory status for immediate availability?

A: CSR1206FKR100 (581,040 pcs), RLP73K2BR10JTD (94,118 pcs), and RL73K2BR10JTD (17,408 pcs) offer the highest inventory levels for rapid procurement. All listed substitutes are active products with confirmed stock.

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

A: Yes, provided all parts meet your circuit's tolerance, power rating, and temperature requirements. Mixing parts with different temperature coefficients or tolerances may affect circuit performance if precision current sensing is critical.
