Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC20JR180EV is determined by strict equivalence across the following parameters:

• Resistance value: 180 mOhms (exact match required)
• Power rating: 0.75W minimum
• Package: 2010 (5025 Metric) form factor
• Composition: Thick film construction
• Application class: Current sense capability
• Temperature coefficient: ±100ppm/°C
• RoHS compliance: ROHS3 Compliant

The substitute parts identified (RL73H2HR18FTDF and RL73H2HR18FTE) meet all these core electrical and mechanical parameters. Both are manufactured by TE Connectivity Passive Product and maintain active product status, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

Both RL73H2HR18FTDF and RL73H2HR18FTE are direct functional equivalents for the obsolete LVC20JR180EV. Key selection factors:

Tolerance Improvement: The substitute parts offer ±1% tolerance compared to the original ±5%, providing superior resistance accuracy for current sense applications where precision is critical.

Extended Temperature Range: Operating range extends to -55°C to 155°C versus the original -40°C to 125°C, accommodating broader environmental conditions.

Active Product Status: Both substitutes are active components with established supply chains, eliminating obsolescence risk.

Compliance Alignment: All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

Packaging Consideration: Substitute parts are supplied in Tape & Reel format, standard for automated assembly processes, whereas the original was bulk packaged.

Frequently Asked Questions (FAQ)

Q: Can RL73H2HR18FTDF and RL73H2HR18FTE be used interchangeably with LVC20JR180EV?

A: Yes. Both substitute parts match the critical electrical parameters (180 mOhms resistance, 0.75W power rating, ±100ppm/°C temperature coefficient) and mechanical specifications (2010 package, thick film composition). The ±1% tolerance of the substitutes is superior to the original ±5%, making them functionally equivalent or better for current sense applications.

Q: What is the difference between RL73H2HR18FTDF and RL73H2HR18FTE?

A: Both parts are electrically and mechanically identical. The difference lies in packaging designation (FTDF versus FTE suffix), which may reflect different tape reel configurations or supplier variants. Consult the respective datasheets for specific tape specifications if automated assembly compatibility is a concern.

Q: Are the substitute parts suitable for the full operating temperature range of my application?

A: The substitute parts operate from -55°C to 155°C, which exceeds the original component's -40°C to 125°C range. If your application operates within the original range, the substitutes are fully compatible. If your application requires temperatures below -40°C or above 125°C, the substitutes provide additional margin.

Q: Do the substitute parts maintain the same moisture resistance as the original?

A: Yes. Both substitute parts carry MSL 1 (Unlimited) rating, identical to the original LVC20JR180EV, indicating equivalent moisture resistance and handling requirements.

Q: Is the Tape & Reel packaging of the substitutes compatible with my assembly process?

A: Tape & Reel packaging is standard for automated pick-and-place assembly. If your process uses bulk components, coordinate with your supplier or assembly partner regarding packaging conversion or reel specifications for the RL73 series parts.
