Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSS2010JT2L00 is determined by the following critical parameters that must remain constant or improve:

• Resistance value: 2 mOhms (exact match required)
• Package / Case: 2010 (5025 Metric) (mechanical compatibility)
• Power rating: 1W (thermal performance)
• Composition: Metal Element (electrical characteristics)
• Temperature coefficient: ±50ppm/°C (thermal stability)
• Operating temperature range: -55°C ~ 225°C (environmental compatibility)
• Automotive rating: AEC-Q200 (qualification requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The CSS2010FT2L00 qualifies as a substitute because it maintains all critical parameters while offering improved tolerance (±1% versus ±5%), which represents an upgrade in precision without compromising any other specification.

Parameter Comparison

Engineering Selection Recommendations

The CSS2010FT2L00 is a direct substitute for the CSS2010JT2L00 in all applications where the 2010 package footprint and 1W power rating are specified. Both parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and operating temperature range. The CSS2010FT2L00 provides superior tolerance performance at ±1% compared to the ±5% tolerance of the CSS2010JT2L00, making it suitable for applications requiring tighter resistance accuracy. The marginal increase in seated height (0.041" versus 0.035") remains within standard PCB assembly tolerances for the 2010 package class. Selection between these parts should be based on tolerance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CSS2010FT2L00 replace CSS2010JT2L00 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, and automotive qualification. The CSS2010FT2L00 offers improved tolerance specification without introducing incompatibility.

Q: What is the difference in seated height between these parts?

A: The CSS2010JT2L00 has a maximum seated height of 0.035" (0.90mm), while the CSS2010FT2L00 measures 0.041" (1.04mm) maximum. This 0.006" difference is within standard PCB assembly clearance specifications for 2010 package resistors.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the CSS2010JT2L00 and CSS2010FT2L00 carry AEC-Q200 qualification and are rated for the -55°C to 225°C operating temperature range required for automotive current sense applications.

Q: What tolerance should I specify for my design?

A: Tolerance selection depends on circuit requirements. The CSS2010JT2L00 with ±5% tolerance is suitable for general current sensing. The CSS2010FT2L00 with ±1% tolerance is appropriate for applications requiring higher measurement accuracy or tighter current limit thresholds.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are manufactured from identical metal element composition with matching temperature coefficients.
