SI3010-KS Equivalent & Substitute Parts

Part Overview

The SI3010-KS is a Telecom Interface IC implementing Direct Access Arrangement (DAA) functionality in a 16-SOIC surface mount package. This component provides parallel, SPI, and UART interface capabilities for telecommunications applications. The SI3010-KS is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI3010-KS is determined by strict equivalence across the following parameters:

• Base product number (SI3010 series)
• Function (Direct Access Arrangement)
• Interface configuration (Parallel, SPI, UART)
• Number of circuits (1)
• Voltage supply range (3V ~ 3.6V)
• Supply current (15mA)
• Operating temperature range (0°C ~ 70°C)
• Package type (16-SOIC with identical physical dimensions)
• Mounting type (Surface Mount)

The SI3010-F-FS meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete SI3010-KS.

Parameter Comparison

Engineering Selection Recommendations

The SI3010-F-FS is the direct equivalent for the obsolete SI3010-KS. Both components share identical electrical specifications, interface configurations, and physical packaging. The SI3010-F-FS is currently in active production status, ensuring availability for replacement and new designs.

The primary distinction between these parts is the Moisture Sensitivity Level (MSL): the SI3010-KS carries MSL 1 (unlimited shelf life), while the SI3010-F-FS carries MSL 3 (168-hour floor life after moisture exposure). This difference requires adherence to standard moisture handling and storage protocols during component procurement and assembly operations.

Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can the SI3010-F-FS directly replace the SI3010-KS in existing designs?

A: Yes. The SI3010-F-FS is electrically and mechanically equivalent to the SI3010-KS across all specified parameters, including voltage supply, current consumption, operating temperature range, interface types, and 16-SOIC package dimensions.

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

A: The SI3010-KS has MSL 1 (unlimited shelf life), while the SI3010-F-FS has MSL 3 (168-hour floor life). MSL 3 components require standard moisture control measures during storage and assembly. This does not affect electrical performance or long-term reliability in deployed applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical ECCN (5A991B) and HTSUS (8542.39.0001) classifications. The SI3010-KS is RoHS non-compliant; RoHS status for the SI3010-F-FS is not specified in the provided data.

Q: What packaging options are available for the SI3010-F-FS?

A: The SI3010-F-FS is supplied in Tube packaging. Packaging specifications for the SI3010-KS are not provided in the available data.

Q: Are there any other SI3010 variants available?

A: Based on the provided data, the SI3010-F-FS is the documented substitute for the SI3010-KS. Additional variants may exist; consult component datasheets and manufacturer specifications for comprehensive product line information.
