Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSS2728FT25L0 is determined by the following critical parameters:

• Resistance value: Must be 25 mOhms
• Tolerance: Must be ±1%
• Package: Must be Wide 2827 (7067 Metric), 2728
• Composition: Must be Metal Element
• Temperature Coefficient: Must be ±15ppm/°C
• Operating Temperature: Must support -55°C to 225°C
• Automotive Compliance: Must maintain AEC-Q200 qualification
• RoHS Status: Must be ROHS3 Compliant

The identified substitute part CSSH2728FT25L0 meets all these criteria. The primary difference is an increased power rating (4W versus 3W), which represents an upgrade in thermal capability while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CSS2728FT25L0 and CSSH2728FT25L0 are active production parts from Stackpole Electronics Inc with full AEC-Q200 automotive qualification and ROHS3 compliance. The CSSH2728FT25L0 provides a direct substitute with identical electrical and mechanical characteristics, with the advantage of a higher power rating (4W). This upgrade is suitable for applications where thermal margin is beneficial or where circuit design may require higher power dissipation capability. Both parts share identical package dimensions, termination count, and temperature operating range, ensuring PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can CSSH2728FT25L0 be used as a direct replacement for CSS2728FT25L0?

A: Yes. The CSSH2728FT25L0 is electrically and mechanically compatible. It maintains the same 25 mOhms resistance, ±1% tolerance, ±15ppm/°C temperature coefficient, and Wide 2827 package footprint. The increased 4W power rating does not affect compatibility in applications designed for the 3W part.

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

A: The power rating differs: CSS2728FT25L0 is rated at 3W, while CSSH2728FT25L0 is rated at 4W. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

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

Q: Do these parts require different PCB footprints?

A: No. Both parts use the identical Wide 2827 (7067 Metric), 2728 package with dimensions of 0.264" L x 0.283" W (6.71mm x 7.19mm) and maximum seated height of 0.049" (1.24mm). No layout changes are required for substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both CSS2728FT25L0 and CSSH2728FT25L0 are ROHS3 compliant with MSL rating of 1 (Unlimited).
