Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCANSTA101SM is determined by strict alignment of the following critical parameters:

• Package / Case: 49-LFBGA with 49-NFBGA (7x7) supplier device package
• Voltage - Supply: 3V ~ 3.6V operating range
• Interface Standard: IEEE 1149.1 compliance
• Mounting Type: Surface Mount
• Functional Category: Interface IC for testing equipment

The substitute part SCANSTA101SM/NOPB meets all these criteria, maintaining identical electrical specifications, package geometry, and functional interface requirements. The primary distinction is the packaging format (Bulk vs. standard) and the active product status of the substitute.

Engineering Selection Recommendations

The SCANSTA101SM/NOPB serves as a direct functional equivalent for the obsolete SCANSTA101SM. Selection between these parts should be based on the following factors:

Product Status Consideration: The SCANSTA101SM/NOPB maintains active product status, ensuring continued availability and potential manufacturer support. The original SCANSTA101SM, classified as obsolete, presents long-term supply chain risk.

Compliance Alignment: Both parts share identical export control classifications (ECCN: EAR99) and tariff codes (HTSUS: 8542.39.0001), ensuring regulatory consistency in procurement and deployment.

Electrical and Mechanical Compatibility: Identical voltage specifications (3V ~ 3.6V), package geometry (49-NFBGA 7x7), and IEEE 1149.1 interface compliance ensure direct pin-for-pin and functional compatibility in existing circuit designs.

Packaging Format: The SCANSTA101SM/NOPB is supplied in Bulk packaging, which may differ from the original part's packaging format. Verify packaging requirements for your procurement and assembly processes.
