Substitute Part Grouping Explanation

The CSSH2728FT20L0 qualifies as a substitute for the CSS2728FT20L0 based on the following matching parameters:

• Resistance value: 20 mOhms (identical)
• Tolerance: ±1% (identical)
• Package: Wide 2827 (7067 Metric), 2728 (identical)
• Composition: Metal Element (identical)
• Temperature Coefficient: ±15ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 225°C (identical)
• Automotive Rating: AEC-Q200 (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The primary difference is the power rating: CSSH2728FT20L0 provides 4W versus the original 3W. This represents an upgrade in thermal capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CSS2728FT20L0 and CSSH2728FT20L0 are active production parts from Stackpole Electronics Inc with identical AEC-Q200 automotive qualification and ROHS3 compliance. The CSSH2728FT20L0 provides increased power dissipation capability (4W versus 3W) while maintaining identical electrical characteristics and package footprint. Selection between these parts depends on thermal requirements of the application. The CSSH2728FT20L0 offers higher thermal margin for current sense applications with elevated power dissipation. Both parts are suitable for automotive environments within the specified operating temperature range of -55°C to 225°C.

Frequently Asked Questions (FAQ)

Q: Can CSSH2728FT20L0 be used as a direct replacement for CSS2728FT20L0?

A: Yes. Both parts share identical resistance, tolerance, package dimensions, and electrical specifications. The CSSH2728FT20L0 has a higher power rating (4W vs 3W) and slightly greater seated height (0.055" vs 0.049"), but maintains the same footprint and pin configuration.

Q: What is the primary difference between these two parts?

A: The power rating differs: CSS2728FT20L0 is rated for 3W dissipation, while CSSH2728FT20L0 is rated for 4W. The CSSH variant provides additional thermal capability for applications requiring higher current sensing or power dissipation.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both CSS2728FT20L0 and CSSH2728FT20L0 carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Do these parts have the same package footprint?

A: Both use the Wide 2827 (7067 Metric) package with identical length and width (0.264" L x 0.283" W). The seated height differs slightly (0.049" vs 0.055"), which may require PCB layout verification in space-constrained designs.

Q: Are both parts RoHS compliant?

A: Yes. Both CSS2728FT20L0 and CSSH2728FT20L0 are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).
