Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSSH2728JT4L00 is determined by maintaining electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 4 mOhms
• Power rating: 4W
• Composition: Metal Element
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C to 225°C

Mechanical Parameters (Must Match):

• Package / Case: Wide 2827 (7067 Metric), 2728
• Physical dimensions: 0.264" L x 0.283" W (6.71mm x 7.19mm)
• Height - Seated (Max): 0.049" (1.24mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• Automotive rating: AEC-Q200
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameter (Allowed to Differ):

• Tolerance: The CSSH2728JT4L00 specifies ±5% tolerance. Substitute parts with tighter tolerance specifications (such as ±1%) are acceptable as they provide improved accuracy while maintaining all other electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The CSSH2728FT4L00 is a direct substitute for the CSSH2728JT4L00. Both parts are active products from Stackpole Electronics Inc with identical electrical specifications, mechanical dimensions, and automotive compliance certifications. The primary difference is tolerance specification: the substitute part offers ±1% tolerance compared to the ±5% tolerance of the main part.

Selection between these parts depends on circuit accuracy requirements. The CSSH2728FT4L00 provides tighter tolerance control for applications requiring improved measurement precision in current sensing circuits. Both parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring compatibility with automotive production standards and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can CSSH2728FT4L00 be used as a direct replacement for CSSH2728JT4L00?

A: Yes. The CSSH2728FT4L00 is a direct substitute. All electrical parameters, mechanical dimensions, package specifications, and automotive certifications are identical. The only difference is tolerance: ±1% versus ±5%.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation from the nominal 4 milliohm resistance value. The CSSH2728JT4L00 allows ±5% deviation (3.8 to 4.2 mOhms), while the CSSH2728FT4L00 allows ±1% deviation (3.96 to 4.04 mOhms). Tighter tolerance improves measurement accuracy in current sensing applications.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C to 225°C). Both are ROHS3 compliant and have unlimited moisture sensitivity level (MSL 1).

Q: Do these parts have identical physical dimensions?

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

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±25ppm/°C, meaning resistance changes by a maximum of 25 parts per million for each degree Celsius change in operating temperature.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both CSSH2728JT4L00 and CSSH2728FT4L00 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
