Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2010FTR150 is determined by the following critical parameters:

• Resistance value: 150 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)
• Features: Current Sense (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Moisture sensitivity: MSL 1 (Unlimited) (handling requirement)

The CSR2010FTR150 meets all substitution criteria. Both parts share identical electrical specifications, package dimensions within acceptable mechanical tolerances, and equivalent regulatory certifications. Temperature coefficient variation (±250ppm/°C vs ±100ppm/°C) represents an improvement in the substitute part, maintaining or exceeding performance requirements.

Parameter Comparison

Engineering Selection Recommendations

The CSR2010FTR150 is a direct substitute for the CSRN2010FTR150. Both parts are manufactured by Stackpole Electronics Inc and maintain Active product status. Electrical specifications are identical across resistance, tolerance, power rating, and operating temperature range. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

The substitute part demonstrates improved temperature coefficient performance (±100ppm/°C versus ±250ppm/°C), which provides enhanced stability in temperature-sensitive applications. Mechanical dimensions are compatible within standard PCB assembly tolerances, with the substitute part featuring a slightly reduced seated height (0.026" versus 0.030"), which may provide marginal benefits in space-constrained designs.

Selection between these parts should be based on availability, lead time, and inventory requirements rather than electrical or mechanical limitations.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FTR150 be used as a direct replacement for CSRN2010FTR150?

A: Yes. Both parts share identical electrical specifications (150 mOhms, ±1%, 1W), package type (2010/5025 Metric), and regulatory compliance (ROHS3, REACH Unaffected). Mechanical dimensions are compatible within standard assembly tolerances.

Q: What is the significance of the temperature coefficient difference?

A: The CSR2010FTR150 features a temperature coefficient of ±100ppm/°C compared to ±250ppm/°C for the CSRN2010FTR150. This represents improved thermal stability and is beneficial in precision current sensing applications operating across the full -55°C to 155°C temperature range.

Q: Are there any PCB layout considerations when substituting these parts?

A: The substitute part has a maximum seated height of 0.026" versus 0.030" for the main part. Width dimensions differ slightly (2.54mm versus 2.45mm). These variations are within standard PCB assembly tolerances and do not require layout modifications for typical applications.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Which part should be selected for new designs?

A: Selection should be based on component availability and supply chain requirements. The improved temperature coefficient of the CSR2010FTR150 may provide marginal advantages in precision applications, but both parts are functionally equivalent for the specified operating conditions.
