CSR2010JTR330 Equivalent & Substitute Parts

Part Overview

The CSR2010JTR330 is a 330 mOhms ±5% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This thick film current sense resistor operates across -55°C to 155°C and is designed for precision current measurement applications. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and environmental ratings can be maintained while potentially offering improved specifications or enhanced feature sets.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010JTR330 is determined by the following mandatory parameters:

Resistance value must equal 330 mOhms. Package must be 2010 (5025 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Power rating must be 1W or greater. Operating temperature range must encompass or match -55°C to 155°C. Composition must be thick film. Current sense functionality must be present or compatible with the application circuit.

Tolerance may be tighter (lower value) than ±5% without affecting substitution validity, as this represents improved precision. Temperature coefficient may be lower (improved stability) without affecting substitution validity. Additional features such as automotive qualification (AEC-Q200) or moisture resistance do not prevent substitution and may enhance performance in specific environments.

The substitute part PT2010FK-7W0R33L meets all mandatory substitution criteria while offering improved tolerance (±1% versus ±5%) and enhanced temperature stability (±75ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both CSR2010JTR330 and PT2010FK-7W0R33L are Active status products with ROHS3 compliance and identical MSL ratings. Selection between these parts depends on application-specific requirements:

The CSR2010JTR330 is suitable for general-purpose current sensing applications where ±5% tolerance meets circuit specifications and standard industrial operating conditions apply.

The PT2010FK-7W0R33L is appropriate for applications requiring tighter tolerance control (±1%), improved temperature stability (±75ppm/°C), or automotive environments where AEC-Q200 qualification is mandated. The moisture-resistant thick film composition provides enhanced reliability in humid or corrosive environments.

Both parts are mechanically and electrically interchangeable within the 2010 package footprint. PCB layout modifications are not required for substitution.

Frequently Asked Questions (FAQ)

Q: Can PT2010FK-7W0R33L replace CSR2010JTR330 in existing designs?

A: Yes. Both parts share identical resistance (330 mOhms), power rating (1W), package (2010), operating temperature range (-55°C to 155°C), and current sense functionality. The PT2010FK-7W0R33L offers improved tolerance and temperature coefficient without requiring circuit redesign.

Q: What is the significance of the ±1% tolerance improvement in PT2010FK-7W0R33L?

A: Tighter tolerance reduces resistance variation across the production batch, improving measurement accuracy in current sensing circuits. This is beneficial in precision applications where current measurement error must be minimized.

Q: Does the AEC-Q200 rating on PT2010FK-7W0R33L affect non-automotive applications?

A: No. AEC-Q200 qualification indicates automotive-grade reliability testing and does not restrict use in non-automotive applications. It represents an additional quality assurance level.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical length (5.00mm) and height (0.65mm). Width differs slightly (2.54mm versus 2.50mm), which does not affect PCB footprint compatibility or soldering.

Q: What is the moisture sensitivity level (MSL) rating and why is it relevant?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These parts do not require special moisture control during storage, handling, or assembly, simplifying supply chain management.
