Equivalent & Substitute Parts for LVC20FR330EV

Part Overview

The Ohmite LVC20FR330EV is a 330 mOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) package. This component is designed for current sense applications with moisture-resistant characteristics. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Substitute parts must maintain the same resistance value, tolerance, package footprint, and core electrical specifications to ensure direct compatibility in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

• Resistance value: 330 mOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Application: Current Sense

Secondary Compatibility Factors:

• Power rating equal to or greater than 0.75W
• Temperature coefficient within ±100ppm/°C
• Operating temperature range encompassing the original specification
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Substitute parts are grouped into two categories based on power rating: parts maintaining the original 0.75W rating and parts with upgraded 1W rating. Both categories satisfy the core electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL rating 1, ensuring long-term availability and environmental regulatory compliance.

For equivalent replacement maintaining original specifications: Select 73L6R33F (CTS Resistor Products) or RL73H2HR33FTDF / RL73H2HR33FTE (TE Connectivity Passive Product). These parts maintain the 0.75W power rating and ±100ppm/°C temperature coefficient of the original LVC20FR330EV while providing extended operating temperature ranges (-55°C ~ 125°C or -55°C ~ 155°C).

For upgraded performance: Select CSR2010FTR330 (Stackpole Electronics Inc) or PT2010FK-7W0R33L (YAGEO). These parts provide 1W power rating, offering increased thermal margin. PT2010FK-7W0R33L includes AEC-Q200 automotive qualification and improved temperature coefficient (±75ppm/°C), suitable for applications requiring enhanced reliability.

Frequently Asked Questions (FAQ)

Q: Can I use a 1W rated resistor as a direct substitute for the 0.75W original part? A: Yes. A higher power rating provides additional thermal margin and is electrically compatible. The 1W parts (CSR2010FTR330 and PT2010FK-7W0R33L) maintain identical resistance, tolerance, and package specifications, making them suitable direct substitutes.

Q: Are all substitute parts pin-compatible with the original LVC20FR330EV? A: Yes. All substitute parts use the 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and two terminations, ensuring PCB compatibility without layout modifications.

Q: What is the significance of the temperature coefficient difference in PT2010FK-7W0R33L? A: The PT2010FK-7W0R33L has a ±75ppm/°C temperature coefficient compared to ±100ppm/°C in other parts. This represents improved temperature stability, reducing resistance drift across the operating temperature range. This is beneficial for precision current sensing applications.

Q: Does the AEC-Q200 rating on PT2010FK-7W0R33L affect its use in non-automotive applications? A: No. AEC-Q200 qualification indicates automotive-grade reliability testing and is applicable to any application. Parts meeting automotive standards are suitable for general industrial and commercial use.

Q: Are there any differences in moisture resistance between the substitute parts? A: The original LVC20FR330EV and all substitute parts have MSL rating 1 (Unlimited), indicating equivalent moisture resistance. PT2010FK-7W0R33L explicitly specifies moisture-resistant characteristics, consistent with the original part's moisture-resistant thick film composition.
