Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM98555CCMH is determined by strict alignment of the following critical parameters:

• Functional Category: Power Management (PMIC) with CCD Driver application capability
• Package Type: 64-TFSOP with exposed pad (0.240", 6.10mm Width)
• Voltage Supply Range: 3V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Mounting Technology: Surface Mount
• Base Product Number: LM98555

The substitute part LM98555CCMH/NOPB meets all substitution criteria. This part shares the identical base product number (LM98555), package specification, voltage and temperature operating ranges, and mounting methodology. The primary distinction is product status classification and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The LM98555CCMH/NOPB is a direct functional equivalent for the obsolete LM98555CCMH. Both parts share identical electrical specifications, package geometry, and thermal operating parameters. The substitute part carries Active product status, ensuring continued availability and manufacturing support compared to the Obsolete classification of the original part.

Both parts maintain EAR99 export classification and identical HTSUS commodity codes. The LM98555CCMH/NOPB is supplied in Bulk packaging format, whereas the original part specification does not define packaging format in the provided data.

For applications currently using the LM98555CCMH, transition to the LM98555CCMH/NOPB presents no electrical or mechanical compatibility constraints given the parameter alignment across voltage supply, temperature range, and package specifications.

Frequently Asked Questions (FAQ)

Q: Can the LM98555CCMH/NOPB be used as a direct replacement for the LM98555CCMH?

A: Yes. Both parts share the identical base product number (LM98555), package type (64-TFSOP with exposed pad), voltage supply range (3V ~ 5.5V), and operating temperature range (0°C ~ 70°C). No circuit modifications or PCB layout changes are required.

Q: What is the significance of the "/NOPB" suffix in the part number?

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free). This affects packaging and handling specifications but does not alter electrical or mechanical compatibility.

Q: Why is the original LM98555CCMH classified as Obsolete?

A: Obsolete classification indicates the part is no longer manufactured by the original supplier. The LM98555CCMH/NOPB maintains Active status, ensuring continued production and supply chain availability.

Q: Are there any compliance differences between these parts?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The original part is RoHS non-compliant; RoHS compliance status for the substitute is not specified in the provided data.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute part?

A: MSL data for the LM98555CCMH/NOPB is not provided in the available specifications. Refer to the manufacturer datasheet for detailed moisture handling requirements.
