Parameter Comparison

Engineering Selection Recommendations

The TB67S128FTG,EL is suitable as a substitute for the LC898240-2H in applications requiring motor driver functionality. Selection should be based on the following engineering factors:

Product Lifecycle Status: The TB67S128FTG,EL maintains Active product status, ensuring continued manufacturing support and long-term availability. This addresses the obsolescence of the LC898240-2H.

Regulatory Compliance: Both components satisfy ROHS3 compliance requirements and share identical ECCN and HTSUS classifications, maintaining regulatory equivalence for procurement and international distribution.

Moisture Handling: The TB67S128FTG,EL provides superior moisture sensitivity characteristics (MSL 1 vs. MSL 4), reducing handling and storage constraints during manufacturing and logistics.

Package Footprint Consideration: The TB67S128FTG,EL utilizes a 64-pin VFQFN package (9x9mm) compared to the 48-pin LQFP package (7x7mm) of the LC898240-2H. PCB layout redesign is required for physical substitution.

Frequently Asked Questions (FAQ)

Q: Can the TB67S128FTG,EL be used as a direct pin-for-pin replacement for the LC898240-2H?

A: No. The TB67S128FTG,EL uses a 64-pin VFQFN package while the LC898240-2H uses a 48-pin LQFP package. PCB redesign is necessary to accommodate the different pin count and package geometry.

Q: What are the key compliance factors for substitution?

A: Both components are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. These regulatory alignments support substitution from a compliance perspective.

Q: Why is the TB67S128FTG,EL recommended over the LC898240-2H?

A: The TB67S128FTG,EL is classified as Active, ensuring ongoing manufacturing support and availability. The LC898240-2H is obsolete, making long-term procurement difficult. Additionally, the TB67S128FTG,EL offers improved moisture sensitivity characteristics (MSL 1 vs. MSL 4).

Q: What packaging formats are available for each part?

A: The LC898240-2H is supplied in Tube packaging. The TB67S128FTG,EL is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Are there electrical parameter differences between these parts?

A: The TB67S128FTG,EL provides specified electrical parameters including 5A output current, 4.75V–5.25V supply voltage range, 6.5V–44V load voltage range, and -40°C to 85°C operating temperature.
