Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSS2512JT5L00 is determined by the following criteria:

Critical Parameters (Must Match):

• Resistance value: 5 mOhms
• Package / Case: 2512 (6432 Metric)
• Composition: Metal Element
• Automotive Rating: AEC-Q200
• Operating Temperature Range: -55°C ~ 225°C
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Tolerance: May be improved from ±5% to ±1%
• Power Rating: May be increased from 2W to 3W
• Manufacturer Series: CSS or CSSH series acceptable

Two substitute parts meet these criteria: CSS2512FT5L00 (improved tolerance, same power rating) and CSSH2512FT5L00 (improved tolerance and increased power rating).

Parameter Comparison

Engineering Selection Recommendations

CSS2512JT5L00 (Original Part): Select this part when tolerance specification of ±5% is acceptable and power dissipation does not exceed 2W in the application circuit.

CSS2512FT5L00 (Tolerance Upgrade): Select this part when improved tolerance of ±1% is required for current sensing accuracy while maintaining 2W power rating. This part offers tighter resistance control with reduced height profile (0.035" vs 0.041").

CSSH2512FT5L00 (Tolerance and Power Upgrade): Select this part when both improved tolerance of ±1% and increased power rating of 3W are required. This part provides the highest performance specification within the 2512 package footprint and maintains full AEC-Q200 automotive compliance.

All three parts are active production items with ROHS3 compliance and AEC-Q200 automotive qualification, ensuring compatibility with automotive current sense applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can CSS2512FT5L00 be used as a direct replacement for CSS2512JT5L00?

A: Yes. Both parts share identical resistance value (5 mOhms), package (2512), composition (Metal Element), and automotive rating (AEC-Q200). CSS2512FT5L00 provides improved tolerance (±1% vs ±5%) and is electrically and mechanically compatible. The reduced height (0.035" vs 0.041") may require PCB layout verification in space-constrained designs.

Q: What is the difference between CSS2512FT5L00 and CSSH2512FT5L00?

A: Both parts have identical resistance (5 mOhms) and tolerance (±1%). The primary difference is power rating: CSS2512FT5L00 is rated for 2W while CSSH2512FT5L00 is rated for 3W. CSSH2512FT5L00 also returns to the original height specification of 0.041". Select CSSH2512FT5L00 when application power dissipation exceeds 2W.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. CSS2512JT5L00, CSS2512FT5L00, and CSSH2512FT5L00 all carry AEC-Q200 automotive qualification and are suitable for automotive current sense applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all three parts use the same 2512 (6432 Metric) package and have identical footprints. Assembly processes and reflow profiles are compatible. Height differences (0.035" for CSS2512FT5L00 vs 0.041" for CSS2512JT5L00 and CSSH2512FT5L00) are within standard PCB assembly tolerances.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.
