Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSS2728JT30L0 is determined by the following critical parameters:

• Resistance Value: Must be 30 mOhms
• Package Compatibility: Must use Wide 2827 (7067 Metric), 2728 package
• Mechanical Dimensions: Must maintain 0.264" L x 0.283" W (6.71mm x 7.19mm) footprint and 0.049" (1.24mm) maximum seated height
• Composition: Metal Element construction
• Temperature Coefficient: ±15ppm/°C
• Operating Temperature Range: -55°C to 225°C
• Automotive Compliance: AEC-Q200 qualification
• Environmental Standards: ROHS3 Compliant, REACH Unaffected

Tolerance and power rating variations are permitted substitution parameters. The CSS2728FT30L0 offers improved tolerance (±1% versus ±5%) at the same 3W power rating. The CSSH2728FT30L0 provides both improved tolerance (±1%) and increased power capacity (4W versus 3W) within the same package envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical mechanical compatibility and environmental compliance. Selection between these parts depends on application-specific tolerance and power dissipation requirements:

CSS2728JT30L0 is suitable for applications where ±5% tolerance meets circuit specifications and 3W power dissipation is sufficient.

CSS2728FT30L0 is appropriate for designs requiring tighter tolerance control (±1%) while maintaining the same 3W power rating and identical package footprint.

CSSH2728FT30L0 is applicable for applications demanding both improved tolerance (±1%) and increased thermal headroom with 4W power capacity. This part remains within the same package dimensions, providing enhanced performance margins without layout modifications.

All substitute parts carry active product status, AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring consistency with the original CSS2728JT30L0 specification.

Frequently Asked Questions (FAQ)

Q: Can CSS2728FT30L0 directly replace CSS2728JT30L0 in existing designs?

A: Yes. The CSS2728FT30L0 maintains identical resistance value, package dimensions, and operating temperature range. The improved ±1% tolerance provides tighter performance characteristics without requiring circuit redesign.

Q: What is the primary advantage of CSSH2728FT30L0 over the original part?

A: The CSSH2728FT30L0 combines improved tolerance (±1%) with increased power rating (4W). Both improvements occur within the same package envelope, allowing direct PCB substitution while providing enhanced thermal performance.

Q: Are all three parts suitable for automotive applications?

A: Yes. All parts carry AEC-Q200 qualification and are rated for the identical -55°C to 225°C operating temperature range, confirming suitability for automotive current sensing circuits.

Q: Do package dimensions differ between these parts?

A: No. All three parts use the Wide 2827 (7067 Metric), 2728 package with identical footprint (0.264" L x 0.283" W) and maximum seated height (0.049"), ensuring direct PCB compatibility.

Q: What environmental compliance standards apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original CSS2728JT30L0 specification.
