Substitute Part Grouping Explanation

Substitution of the CSSH2512JT5L00 is determined by strict equivalence across the following critical parameters: resistance value (5 mOhms), power rating (3W), package type (2512), composition (metal element), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 225°C), automotive qualification (AEC-Q200), and compliance certifications (ROHS3, REACH Unaffected). The tolerance specification is the primary differentiator among equivalent parts. The CSSH2512FT5L00 qualifies as a direct substitute with improved tolerance performance (±1% versus ±5%) while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSSH2512JT5L00 and CSSH2512FT5L00 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on tolerance requirements for the application. The CSSH2512JT5L00 with ±5% tolerance is suitable for applications where standard tolerance current sensing is acceptable. The CSSH2512FT5L00 with ±1% tolerance provides improved accuracy for precision current measurement applications. Both parts are mechanically and thermally interchangeable with identical package dimensions, thermal characteristics, and operating ranges. Inventory availability should be considered: CSSH2512JT5L00 has 919 units in stock while CSSH2512FT5L00 has 1107 units in stock.

Frequently Asked Questions (FAQ)

Q: Can CSSH2512FT5L00 be used as a direct replacement for CSSH2512JT5L00?

A: Yes. The CSSH2512FT5L00 is a direct mechanical and electrical substitute. It maintains identical resistance value, power rating, package dimensions, and operating temperature range. The primary difference is improved tolerance specification (±1% versus ±5%).

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: resistance value (5 mOhms), power rating (3W), package type (2512), composition (metal element), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 225°C), and automotive qualification (AEC-Q200). Tolerance is a secondary parameter that may vary among equivalent parts.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the identical 2512 (6432 Metric) package with dimensions of 0.246" L x 0.130" W (6.25mm x 3.30mm) and maximum seated height of 0.041" (1.04mm). They are footprint-compatible for PCB assembly.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both CSSH2512JT5L00 and CSSH2512FT5L00 carry AEC-Q200 qualification and are ROHS3 compliant with REACH Unaffected status, meeting automotive industry standards.

Q: What is the difference in tolerance between these parts?

A: The CSSH2512JT5L00 has ±5% tolerance while the CSSH2512FT5L00 has ±1% tolerance. The ±1% tolerance part provides tighter resistance accuracy for applications requiring precision current measurement.
