LVC06FR050EV Equivalent & Substitute Parts

Part Overview

The LVC06FR050EV is a 50 mOhms ±1% thick film chip resistor in 1206 (3216 Metric) package rated for 0.5W power dissipation. Manufactured by Ohmite, this current sense resistor is designed for moisture-resistant applications with operating temperature range of -40°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC06FR050EV is determined by strict equivalence across the following parameters:

• Resistance value: 50 mOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in operating temperature range, physical dimensions within tolerance, and product status (active vs. obsolete) are noted but do not disqualify substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CSR1206FK50L0, 73E4R050F, and CSR1206FT50L0—meet the electrical and mechanical requirements for direct substitution of the obsolete LVC06FR050EV. Selection among these equivalents should be based on:

Product Availability and Supply Chain: CSR1206FK50L0 and CSR1206FT50L0 (Stackpole Electronics) are active products with substantial inventory (117,047 and 5,859 units respectively), ensuring long-term availability. 73E4R050F (CTS Resistor Products) is also active with 950 units in stock.

Compliance Certifications: All substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) ratings, matching the original part's environmental and handling requirements. CSR1206FK50L0 and CSR1206FT50L0 include REACH Unaffected status; 73E4R050F also includes REACH Unaffected status.

Operating Temperature Envelope: CSR1206FK50L0 and CSR1206FT50L0 extend the operating range to -55°C to 155°C, providing broader thermal margin. 73E4R050F maintains -55°C to 125°C, which encompasses the original -40°C to 125°C specification.

Physical Dimensions: CSR1206FK50L0 and CSR1206FT50L0 have slightly reduced dimensions (0.120" L x 0.061" W vs. 0.126" L x 0.063" W) with identical height (0.026"), ensuring PCB layout compatibility. 73E4R050F matches the original dimensions exactly (0.126" L x 0.063" W) with marginally increased height (0.028" vs. 0.026").

Frequently Asked Questions (FAQ)

Q: Can CSR1206FK50L0, 73E4R050F, and CSR1206FT50L0 be used interchangeably with LVC06FR050EV?

A: Yes. All three parts meet the core electrical specifications (50 mOhms ±1%, 0.5W, ±100ppm/°C) and mechanical requirements (1206 package, thick film composition, RoHS3 compliance, MSL 1). They are direct functional equivalents.

Q: What is the difference between CSR1206FK50L0 and CSR1206FT50L0?

A: Both are Stackpole Electronics CSR series 50 mOhm resistors with identical electrical specifications and operating temperature range (-55°C to 155°C). The primary difference is packaging: CSR1206FK50L0 is supplied in Tape & Reel format with 117,047 units available, while CSR1206FT50L0 is also Tape & Reel with 5,859 units available. Both have identical physical dimensions and performance characteristics.

Q: Are there any dimensional concerns when substituting these parts on existing PCBs?

A: CSR1206FK50L0 and CSR1206FT50L0 have slightly smaller length and width (0.120" x 0.061" vs. 0.126" x 0.063") but identical height (0.026"), ensuring compatibility with existing 1206 footprints. 73E4R050F matches the original dimensions exactly with negligible height increase (0.028" vs. 0.026"), which remains within standard PCB assembly tolerances.

Q: Why is the LVC06FR050EV obsolete?

A: The LVC06FR050EV is marked as obsolete by Ohmite. All listed substitutes are active products from established manufacturers (Stackpole Electronics and CTS Resistor Products), ensuring continued availability and supply chain stability.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part. CSR1206FK50L0, 73E4R050F, and CSR1206FT50L0 also include REACH Unaffected status, providing additional regulatory assurance.
