LM98555CCMHX CCD Driver PMIC Equivalent & Substitute Parts

Part Overview

The LM98555CCMHX is a CCD Driver PMIC manufactured by Texas Instruments, designed for charge-coupled device applications requiring integrated power management and driver functionality. This component operates across a 3V to 5.5V supply voltage range and is housed in a 64-TFSOP package with exposed pad for thermal management.

The LM98555CCMHX carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, design refresh, and procurement continuity. Direct substitutes maintain identical electrical specifications and mechanical compatibility, enabling drop-in replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM98555CCMHX is determined by strict alignment across the following critical parameters:

Electrical Compatibility:

• Voltage supply range: 3V ~ 5.5V (exact match required)
• Operating temperature range: 0°C ~ 70°C (exact match required)
• Functional classification: CCD Driver PMIC

Mechanical Compatibility:

• Package type: 64-TFSOP with exposed pad (exact match required)
• Mounting method: Surface Mount
• Physical dimensions: 0.240" width, 6.10mm width specification

Regulatory & Compliance:

• Base product number: LM98555 (same silicon family)
• ECCN and HTSUS classifications must align for export and tariff purposes

The LM98555CCMHX/NOPB variant qualifies as a direct substitute, sharing identical electrical specifications, package configuration, and functional performance characteristics. The "/NOPB" suffix indicates lead-free plating compliance, representing a manufacturing variant of the same base product.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LM98555CCMHX/NOPB

The LM98555CCMHX/NOPB is the qualified direct substitute for the obsolete LM98555CCMHX. Both components share identical electrical performance across the specified voltage supply range (3V ~ 5.5V) and operating temperature window (0°C ~ 70°C). Package geometry, pin configuration, and thermal characteristics are functionally equivalent.

The LM98555CCMHX/NOPB carries Active product status, ensuring ongoing availability and manufacturing support. This variant incorporates lead-free plating, aligning with modern manufacturing standards and environmental compliance frameworks. Both components maintain identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, supporting consistent export and procurement documentation.

For systems currently deployed with the obsolete LM98555CCMHX, transition to the LM98555CCMHX/NOPB requires no circuit modifications, PCB layout changes, or firmware updates. Pin-for-pin compatibility and electrical equivalence enable direct socket replacement.

Frequently Asked Questions (FAQ)

Q: Can the LM98555CCMHX/NOPB replace the LM98555CCMHX in existing designs?

A: Yes. Both components are pin-for-pin compatible with identical electrical specifications across the 3V to 5.5V supply range and 0°C to 70°C operating temperature. No circuit redesign is required.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" designation specifies lead-free plating on the component leads, representing a manufacturing variant of the base LM98555 product. Electrical and functional performance remains unchanged.

Q: Are there differences in package dimensions between these parts?

A: No. Both the LM98555CCMHX and LM98555CCMHX/NOPB use the 64-TFSOP package with 0.240" width and 6.10mm specification, including exposed pad for thermal management. PCB footprints are identical.

Q: Why is the original LM98555CCMHX marked as Obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The LM98555CCMHX/NOPB maintains the same silicon functionality with Active status, ensuring continued supply and support.

Q: Do these components have identical moisture sensitivity requirements?

A: The LM98555CCMHX specifies MSL 4 (72 Hours). Storage and handling protocols should follow this classification for both variants to ensure reliability.

Q: Are export classifications identical for both parts?

A: Yes. Both components carry ECCN EAR99 and HTSUS 8542.39.0001 classifications, maintaining consistent export documentation and tariff treatment.
