SCANSTA111SMX Equivalent & Substitute Parts

Part Overview

The SCANSTA111SMX is a specialized interface integrated circuit manufactured by Texas Instruments, designed for testing equipment applications. This component operates within the IEEE 1149.1 standard framework and is housed in a 49-LFBGA package configuration. The main part number SCANSTA111SMX carries a product status designation of "Not For New Designs," which necessitates identification of functionally equivalent alternatives for ongoing production and new design implementations. The substitute part SCANSTA111SMX/NOPB maintains identical electrical and mechanical specifications while offering active product status and significantly higher inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCANSTA111SMX is determined by strict alignment across the following critical parameters:

• Base product number (SCANSTA111)
• Package configuration (49-LFBGA / 49-NFBGA 7x7)
• Electrical specifications (3V ~ 3.6V supply voltage)
• Interface standard (IEEE 1149.1)
• Mounting type (Surface Mount)
• Regulatory compliance (ROHS3, REACH Unaffected)

The SCANSTA111SMX/NOPB variant satisfies all substitution criteria. The "/NOPB" suffix indicates a lead-free, halogen-free packaging variant that maintains functional and electrical equivalence while offering improved product lifecycle status and supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The SCANSTA111SMX/NOPB is the direct functional equivalent for applications currently utilizing SCANSTA111SMX. Selection of SCANSTA111SMX/NOPB is supported by the following engineering considerations:

• Active product status ensures long-term availability and manufacturing support
• Identical electrical specifications and package configuration guarantee pin-for-pin compatibility
• ROHS3 and REACH compliance certifications are maintained across both variants
• Higher inventory availability (113,128 units) compared to the legacy variant (4,557 units) reduces supply chain risk
• MSL rating difference (4 versus 3) reflects standard lead-free packaging practices and does not impact functional performance in testing equipment applications

Frequently Asked Questions (FAQ)

Q: Can SCANSTA111SMX/NOPB be used as a direct replacement for SCANSTA111SMX?

A: Yes. Both parts share identical base product number (SCANSTA111), package configuration (49-LFBGA), electrical specifications (3V ~ 3.6V), and interface standard (IEEE 1149.1). The "/NOPB" designation indicates lead-free, halogen-free packaging that maintains functional equivalence.

Q: What does the "Not For New Designs" status mean for SCANSTA111SMX?

A: This designation indicates the part is in mature or end-of-life phase. Texas Instruments recommends using SCANSTA111SMX/NOPB for new designs and ongoing production to ensure long-term supply availability and manufacturing support.

Q: Are there differences in moisture sensitivity between the two variants?

A: SCANSTA111SMX carries MSL 3 (168 hours), while SCANSTA111SMX/NOPB carries MSL 4 (72 hours). Both ratings are standard for their respective packaging types and do not affect functional performance in testing equipment applications.

Q: Is the 49-NFBGA (7x7) package compatible with 49-LFBGA specifications?

A: Yes. The 49-NFBGA (7x7) is the supplier device package designation for the 49-LFBGA case style. Both designations refer to the same physical and electrical package configuration.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both SCANSTA111SMX and SCANSTA111SMX/NOPB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
