Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSS2725JT3L00 is determined by the following critical parameters:

• Resistance value: 3 mOhms (exact match required)
• Power rating: 4W (exact match required)
• Package / Case: Nonstandard 2725 (exact match required)
• Composition: Metal Element (exact match required)
• Operating temperature range: -55°C to 225°C (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The CSS2725FT3L00 qualifies as a substitute part because it maintains identical specifications across all critical parameters. The primary difference is tolerance specification: the substitute offers ±1% tolerance compared to the main part's ±5% tolerance. This represents an upgrade in precision without compromising any functional or environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CSS2725JT3L00 and CSS2725FT3L00 are active production parts from Stackpole Electronics Inc with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on tolerance requirements specific to the application circuit design. The CSS2725FT3L00 provides tighter tolerance control (±1%) and is suitable for applications requiring higher precision in current sensing or measurement circuits. The CSS2725JT3L00 maintains standard tolerance (±5%) and is appropriate for general-purpose current sense applications where tolerance margins are adequate. Both parts share identical physical dimensions, thermal characteristics, and environmental ratings, ensuring mechanical and thermal compatibility in board-level integration.

Frequently Asked Questions (FAQ)

Q: Can CSS2725FT3L00 be used as a direct replacement for CSS2725JT3L00?

A: Yes. The CSS2725FT3L00 is a direct substitute. It maintains identical resistance value, power rating, package dimensions, operating temperature range, and automotive qualification. The tolerance specification is tighter (±1% versus ±5%), which represents an upgrade in precision without introducing any compatibility issues.

Q: What is the physical difference between these parts?

A: The seated height differs slightly: CSS2725JT3L00 has a maximum seated height of 0.045" (1.14mm), while CSS2725FT3L00 has a maximum seated height of 0.053" (1.34mm). Both parts use the identical nonstandard 2725 package with dimensions of 0.268" L x 0.254" W (6.81mm x 6.45mm). This height variation must be considered in PCB layout and assembly clearance planning.

Q: Are both parts suitable for automotive applications?

A: Yes. Both CSS2725JT3L00 and CSS2725FT3L00 carry AEC-Q200 automotive qualification and are compliant with ROHS3 regulations. Both are rated for the full automotive temperature range of -55°C to 225°C with identical temperature coefficients of ±50 ppm/°C.

Q: Which part should be selected for current sensing circuits?

A: Selection depends on measurement accuracy requirements. The CSS2725FT3L00 with ±1% tolerance is preferred for precision current measurement applications. The CSS2725JT3L00 with ±5% tolerance is suitable for general current sensing where tolerance margins accommodate the wider specification band.

Q: Is inventory availability a factor in part selection?

A: The CSS2725FT3L00 has significantly higher inventory availability (4148 pcs in stock) compared to CSS2725JT3L00 (793 pcs in stock). For high-volume production or extended lead time mitigation, the CSS2725FT3L00 may offer supply chain advantages while maintaining full functional and environmental compatibility.
