LVC06JR270EV Equivalent & Substitute Parts

Part Overview

The LVC06JR270EV is a 270 mOhms ±5% 0.5W thick film chip resistor in 1206 package manufactured by Ohmite. This component is designed for current sense applications with moisture-resistant characteristics. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the LVC06JR270EV is determined by the following critical parameters:

Resistance Value: 270 mOhms (exact match required)
Package Type: 1206 (3216 Metric) form factor
Composition: Thick film construction
Application: Current sense functionality
Compliance: ROHS3 compliance maintained

Substitute parts are grouped into two categories based on tolerance and power rating specifications:

Category 1 - Direct Tolerance Match (±5%) Parts maintaining the original ±5% tolerance specification with equivalent or superior power ratings and operating temperature ranges.

Category 2 - Tolerance Upgrade (±1%) Parts offering improved tolerance performance (±1%) with equivalent or superior power ratings, suitable for applications requiring tighter resistance control.

Engineering Selection Recommendations

Direct Replacement (Active Status)

RLP73K2BR27JTD from TE Connectivity provides the closest functional match to the obsolete LVC06JR270EV. This part maintains identical resistance, tolerance, and power rating specifications while offering an extended operating temperature range (-55°C ~ 155°C versus -40°C ~ 125°C). Product status is active with established supply availability.

Tolerance-Upgraded Options

RLP73K2BR27FTDF, CSR1206FTR270, and RCWE1206R270FKEA offer ±1% tolerance with 0.5W power rating. These parts are suitable for applications requiring improved resistance accuracy. All three maintain ROHS3 compliance and active product status.

RCWE1206R270FKEA includes AEC-Q200 automotive qualification and moisture-resistant features, making it appropriate for automotive and harsh environment applications.

CSR1206FTR270 provides the lowest temperature coefficient (±100ppm/°C) among available options, beneficial for temperature-sensitive circuit designs.

Lower Power Option

RL73K2BR27JTD from TE Connectivity offers 0.25W power rating with ±5% tolerance. This part is suitable only for applications where 0.25W dissipation is sufficient, as it provides reduced power handling compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can RL73K2BR27JTD (0.25W) replace the LVC06JR270EV (0.5W)?

A: RL73K2BR27JTD is electrically compatible in terms of resistance and tolerance but has reduced power dissipation capability (0.25W versus 0.5W). Use this part only if circuit analysis confirms maximum power dissipation does not exceed 0.25W.

Q: What is the advantage of ±1% tolerance parts over ±5% tolerance?

A: ±1% tolerance parts (RLP73K2BR27FTDF, CSR1206FTR270, RCWE1206R270FKEA) provide tighter resistance control, reducing circuit performance variation. Select these for precision current sensing applications or where tolerance stack-up is critical.

Q: Is RCWE1206R270FKEA suitable for automotive applications?

A: Yes. RCWE1206R270FKEA carries AEC-Q200 automotive qualification and is appropriate for automotive and high-reliability applications requiring enhanced environmental performance.

Q: Are all substitute parts in 1206 package compatible with the original PCB footprint?

A: All listed substitute parts use 1206 (3216 Metric) package. Physical dimensions are within acceptable tolerance for standard 1206 footprints. Verify specific height specifications if space constraints exist.

Q: What is the operating temperature difference between the original and substitute parts?

A: The LVC06JR270EV operates -40°C ~ 125°C. All active substitute parts extend this range to -55°C ~ 155°C, providing broader temperature coverage for demanding applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original part's environmental standards.
