Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSS2728FT50L0 is determined by the following critical parameters:

• Resistance value: 50 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Element (exact match required)
• Temperature Coefficient: ±15 ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 225°C (exact match required)
• Package/Case: Wide 2827 (7067 Metric), 2728 (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The CSSH2728FT50L0 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering an increased power rating of 4W compared to the original 3W specification. This upgrade in power handling capability does not compromise compatibility and provides enhanced thermal performance margins.

Parameter Comparison

Engineering Selection Recommendations

The CSSH2728FT50L0 is a qualified substitute for the CSS2728FT50L0 based on maintained compliance with AEC-Q200 automotive standards and ROHS3 certification. Both parts share identical electrical characteristics, mechanical dimensions, and thermal specifications. The substitute part offers increased power dissipation capability at 4W versus 3W, providing additional thermal margin in current sensing applications. Selection between these parts should be based on application power requirements and inventory availability. The CSSH2728FT50L0 maintains full compatibility with existing designs specified for the CSS2728FT50L0.

Frequently Asked Questions (FAQ)

Q: Can the CSSH2728FT50L0 be used as a direct replacement for the CSS2728FT50L0?

A: Yes. The CSSH2728FT50L0 maintains identical resistance, tolerance, temperature coefficient, operating temperature range, package dimensions, and automotive qualification. The increased 4W power rating does not affect electrical compatibility.

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

A: The power rating differs: CSS2728FT50L0 is rated at 3W while CSSH2728FT50L0 is rated at 4W. All other electrical and mechanical specifications are identical.

Q: Are both parts qualified for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry standards.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts use the Wide 2827 (7067 Metric) package with identical dimensions of 0.264" L x 0.283" W (6.71mm x 7.19mm) and maximum seated height of 0.049" (1.24mm).

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity concerns.

Q: Which part should be selected for new designs?

A: Selection depends on application power dissipation requirements. If the application requires 3W or less, either part is suitable. If higher thermal margins are desired, the CSSH2728FT50L0 with 4W rating is appropriate.
