Substitute Part Grouping Explanation

Substitution of the CSS2728JT20L0 is permissible with the CSSH2728FT20L0 based on the following criteria:

Matching Parameters (Required for Substitution):

• Resistance value: 20 mOhms (identical)
• Package type: Wide 2827 (7067 Metric) (identical)
• Temperature coefficient: ±15ppm/°C (identical)
• Operating temperature range: -55°C to 225°C (identical)
• Composition: Metal Element (identical)
• Automotive qualification: AEC-Q200 (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Enhanced Specifications in Substitute:

• Tolerance improved from ±5% to ±1%
• Power rating increased from 3W to 4W

The CSSH2728FT20L0 provides superior performance characteristics while maintaining full mechanical and electrical compatibility with the original CSS2728JT20L0 footprint and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both CSS2728JT20L0 and CSSH2728FT20L0 are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. The CSSH2728FT20L0 is suitable as a direct substitute where improved tolerance (±1% versus ±5%) and increased power dissipation capability (4W versus 3W) are beneficial. Both parts maintain identical thermal performance characteristics and mechanical compatibility within the Wide 2827 package footprint. Selection between these parts depends on application-specific requirements for tolerance precision and thermal margin.

Frequently Asked Questions (FAQ)

Q: Can CSSH2728FT20L0 replace CSS2728JT20L0 in existing designs?

A: Yes. The CSSH2728FT20L0 maintains identical resistance value, package dimensions, temperature coefficient, and operating temperature range. The substitute provides enhanced tolerance and power rating specifications.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use the identical Wide 2827 (7067 Metric) package with matching footprint dimensions of 0.264" L × 0.283" W (6.71mm × 7.19mm). Maximum seated height differs slightly (0.049" for CSS2728JT20L0 versus 0.055" for CSSH2728FT20L0), which remains within standard PCB assembly clearance tolerances.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both CSS2728JT20L0 and CSSH2728FT20L0 carry AEC-Q200 qualification and are suitable for automotive applications across the -55°C to 225°C operating range.

Q: What is the primary advantage of the CSSH2728FT20L0 substitute?

A: The CSSH2728FT20L0 offers tighter tolerance (±1% versus ±5%) and higher power rating (4W versus 3W), providing improved accuracy in current sensing circuits and greater thermal headroom.

Q: Are RoHS and REACH compliance identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity level (MSL 1 - Unlimited).
