Substitute Part Grouping Explanation

The CSSH2512FT5L00 qualifies as a substitute for the CSS2512FT5L00 based on the following criteria:

Matching Parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Metal Element
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 225°C
• Automotive Rating: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: 3W (upgrade from 2W)
• Height - Seated (Max): 0.041" (1.04mm) vs. 0.035" (0.90mm)

The CSSH2512FT5L00 provides increased power dissipation capability while maintaining all critical electrical and mechanical specifications. The height difference remains within the 2512 package envelope and does not affect PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CSS2512FT5L00 and CSSH2512FT5L00 are active production parts from Stackpole Electronics Inc with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application power dissipation requirements:

The CSS2512FT5L00 (2W rating) is suitable for applications where the calculated power dissipation does not exceed 2W under worst-case operating conditions.

The CSSH2512FT5L00 (3W rating) provides additional thermal margin and is suitable for applications requiring higher power dissipation capability or where thermal management constraints necessitate a higher-rated component. The increased height of 0.006" (0.14mm) remains within standard 2512 package tolerances and does not impact PCB layout compatibility.

Both parts maintain identical electrical characteristics, temperature performance, and compliance certifications, ensuring functional equivalence in current sense applications.

Frequently Asked Questions (FAQ)

Q: Can CSSH2512FT5L00 be used as a direct replacement for CSS2512FT5L00?

A: Yes. Both parts share identical resistance, tolerance, temperature coefficient, operating temperature range, and AEC-Q200 automotive qualification. The CSSH2512FT5L00 provides higher power rating (3W vs. 2W) and is mechanically compatible within the 2512 package specification.

Q: What is the height difference between these parts?

A: CSS2512FT5L00 has a maximum seated height of 0.035" (0.90mm), while CSSH2512FT5L00 has a maximum seated height of 0.041" (1.04mm). This 0.006" (0.14mm) difference is within the 2512 package envelope and does not affect standard PCB layout or assembly processes.

Q: Are both parts suitable for automotive applications?

A: Yes. Both CSS2512FT5L00 and CSSH2512FT5L00 carry AEC-Q200 qualification and are rated for automotive use across the -55°C to 225°C operating temperature range.

Q: What determines substitution eligibility for these current sense resistors?

A: Substitution is based on matching resistance value (5 mOhms), tolerance (±1%), package type (2512), composition (Metal Element), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 225°C), and automotive qualification (AEC-Q200). Power rating may be upgraded without affecting compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Compliance certifications are equivalent.
