Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FTR330 is determined by the following critical parameters:

• Resistance value: 330 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 (minimum requirement)

The PT2010FK-7W0R33L from YAGEO meets all substitution criteria. This part maintains identical electrical specifications and package dimensions while offering enhanced features including AEC-Q200 automotive qualification, moisture-resistant composition, and an improved temperature coefficient of ±75ppm/°C compared to the original ±100ppm/°C.

Parameter Comparison

Engineering Selection Recommendations

The PT2010FK-7W0R33L is a direct electrical and mechanical substitute for the CSR2010FTR330. Both parts are active products with ROHS3 compliance and identical core specifications. The YAGEO part offers additional value through AEC-Q200 automotive qualification and moisture-resistant composition, making it suitable for applications requiring enhanced reliability. The improved temperature coefficient of ±75ppm/°C provides superior stability compared to the original ±100ppm/°C specification. Dimensional compatibility is maintained with negligible width variation (2.50mm vs 2.54mm) that does not impact PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PT2010FK-7W0R33L replace CSR2010FTR330 in existing designs?

A: Yes. Both parts share identical resistance (330 mOhms), tolerance (±1%), power rating (1W), package (2010), and operating temperature range (-55°C ~ 155°C). Mechanical dimensions are compatible with negligible variation. No design changes are required.

Q: What is the difference in temperature coefficient between these parts?

A: The CSR2010FTR330 has a temperature coefficient of ±100ppm/°C, while the PT2010FK-7W0R33L has ±75ppm/°C. The YAGEO part provides improved temperature stability.

Q: Does the PT2010FK-7W0R33L require different handling or storage?

A: Both parts have identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control is required during storage or handling.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The PT2010FK-7W0R33L additionally carries AEC-Q200 automotive qualification, which is not a limitation but an enhancement for applications requiring automotive-grade reliability.

Q: What is the physical size difference?

A: The length is identical at 0.197" (5.00mm). Width differs slightly: CSR2010FTR330 is 0.100" (2.54mm) while PT2010FK-7W0R33L is 0.098" (2.50mm). Both have identical height of 0.026" (0.65mm). This minimal variation does not affect PCB footprint compatibility.
