Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI3018-GS is determined by strict equivalence across the following critical parameters:

• Function: Direct Access Arrangement (DAA) implementation
• Interface Protocols: Parallel, SPI, and UART support
• Package Type: 16-SOIC form factor with 0.154" (3.90mm) width
• Electrical Specifications: 3V to 3.6V supply voltage range and 8.5mA supply current
• Operating Temperature Range: -40°C to 85°C
• Circuit Count: Single circuit configuration
• Mounting Technology: Surface mount assembly

The SI3018-F-GS meets all substitution criteria as a direct functional equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SI3018-F-GS is the direct substitute for the obsolete SI3018-GS. Both components share identical functional specifications, electrical parameters, and mechanical packaging. The SI3018-F-GS maintains active product status, ensuring continued availability and supply chain reliability.

The SI3018-F-GS provides additional compliance certifications including ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. The moisture sensitivity level difference (MSL 1 versus MSL 3) reflects standard industry variations in packaging and storage requirements and does not affect functional compatibility.

Selection of the SI3018-F-GS is appropriate for direct replacement in existing designs and for new implementations requiring DAA telecom interface functionality with the specified electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SI3018-F-GS directly replace the SI3018-GS in existing designs?

A: Yes. The SI3018-F-GS is a direct functional equivalent with identical supply voltage (3V to 3.6V), supply current (8.5mA), operating temperature range (-40°C to 85°C), interface protocols (Parallel, SPI, UART), and 16-SOIC package configuration. Pin-for-pin compatibility is maintained.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The SI3018-GS carries MSL 1 (unlimited moisture sensitivity protection), while the SI3018-F-GS carries MSL 3 (168 hours protection). This difference reflects packaging and storage handling requirements. MSL 3 components require controlled humidity storage and have defined floor life limits. Both ratings are standard for their respective product generations and do not affect electrical performance or functional compatibility.

Q: Are there compliance differences between these parts?

A: The SI3018-F-GS includes ROHS3 compliance and REACH unaffected certification. Both components share identical ECCN (5A991B) and HTSUS (8542.39.0001) classifications. The additional compliance certifications on the SI3018-F-GS support modern regulatory environments.

Q: Why is the SI3018-GS classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by the original supplier. The SI3018-F-GS, as an active equivalent, provides continued access to this DAA telecom interface functionality.

Q: Are there any packaging format differences?

A: The SI3018-GS packaging format is not specified in available data. The SI3018-F-GS is supplied in tube packaging. Both components use identical 16-SOIC surface mount package geometry (0.154", 3.90mm width).
