LVC06FR390EV Equivalent & Substitute Parts

Part Overview

The LVC06FR390EV is a 390 mOhms ±1% 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Ohmite. Designed for current sense applications with moisture-resistant characteristics, this component operates across -40°C to 125°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and ensure supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC06FR390EV is determined by strict equivalence across the following parameters:

• Resistance value: 390 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Application suitability: Current Sense
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 or better

The identified substitute parts meet all core electrical and mechanical requirements. Variations in temperature coefficient, operating temperature range, and additional certifications (such as AEC-Q200) represent enhanced or extended capabilities beyond the minimum specification.

Parameter Comparison

Engineering Selection Recommendations

Both RLP73K2BR39FTDF and RCWE1206R390FKEA are active production alternatives suitable for replacing the obsolete LVC06FR390EV.

RLP73K2BR39FTDF (TE Connectivity) provides direct functional equivalence with extended operating temperature range (-55°C to 155°C) compared to the original specification. This part maintains current sense capability and meets all core electrical parameters.

RCWE1206R390FKEA (Vishay Dale) offers the same extended temperature range and adds AEC-Q200 automotive qualification. This part includes moisture-resistant features matching the original design intent and maintains the ±100ppm/°C temperature coefficient of the LVC06FR390EV. Selection of this part is appropriate for applications requiring automotive-grade reliability or extended environmental performance.

Both substitutes are available in active production with established supply chains, eliminating obsolescence risk associated with the original component.

Frequently Asked Questions (FAQ)

Q: Can RLP73K2BR39FTDF directly replace LVC06FR390EV in existing designs?

A: Yes. Both parts share identical resistance (390 mOhms), tolerance (±1%), power rating (0.5W), package (1206), and composition (thick film). The TE Connectivity part extends the operating temperature range to -55°C to 155°C, which is compatible with designs specified for -40°C to 125°C operation.

Q: What is the difference between RLP73K2BR39FTDF and RCWE1206R390FKEA?

A: Both parts meet core electrical specifications. RCWE1206R390FKEA includes AEC-Q200 automotive qualification and maintains the ±100ppm/°C temperature coefficient of the original part, while RLP73K2BR39FTDF has a ±200ppm/°C temperature coefficient. For applications requiring tighter temperature stability or automotive compliance, RCWE1206R390FKEA is the preferred selection.

Q: Are all three parts available in the same packaging format?

A: All three parts are supplied in 1206 (3216 Metric) package with 2 terminations. RLP73K2BR39FTDF and RCWE1206R390FKEA are available in Tape & Reel (TR) format. Physical dimensions vary slightly within tolerance: LVC06FR390EV measures 0.126" L × 0.063" W, while substitutes measure 0.122" L × 0.061" W or 0.122" L × 0.063" W. These variations remain within standard PCB pad tolerances for 1206 components.

Q: Do the substitute parts maintain moisture resistance?

A: Both substitutes meet MSL 1 (Unlimited) rating. RCWE1206R390FKEA explicitly includes moisture-resistant thick film composition. RLP73K2BR39FTDF meets the same MSL specification, ensuring equivalent moisture performance for standard PCB assembly and storage conditions.

Q: Which part should be selected for new designs?

A: RCWE1206R390FKEA is recommended for new designs due to active production status, AEC-Q200 qualification, and maintained temperature coefficient matching the original specification. This part provides the broadest compatibility with existing design documentation and supply chain stability.
