DS3680DR Equivalent & Substitute Parts

Part Overview

The DS3680DR is a telecom interface IC manufactured by Texas Instruments in a 14-SOIC package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The DS3680DR serves specialized telecom interface applications with a 4-circuit configuration and operates across the 0°C to 70°C temperature range. Due to its obsolete status, sourcing equivalent or substitute components is necessary for production continuity and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS3680DR is determined by the following critical parameters:

• Functional Category: Both the main part and substitute must operate within the Interface category for telecom applications
• Circuit Configuration: The number of circuits (4) represents the functional complexity and pin requirements
• Operating Temperature Range: The 0°C to 70°C specification defines the thermal operating envelope
• Mounting Technology: Surface mount compatibility ensures PCB integration feasibility
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status maintain environmental and regulatory alignment
• Moisture Sensitivity: MSL rating affects storage and handling requirements

The AD9888KSZ-170 is identified as a manufacturer-recommended substitute based on functional interface capability and regulatory compliance alignment, though it operates in a different package format (128-MQFP versus 14-SOIC).

Parameter Comparison

Engineering Selection Recommendations

The AD9888KSZ-170 is designated as the manufacturer-recommended substitute for the obsolete DS3680DR. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new implementations and legacy system support.

The primary consideration for component selection is the package format transition from 14-SOIC to 128-MQFP. This change requires PCB redesign and layout modifications. The AD9888KSZ-170 is currently in active production status, providing supply chain stability and long-term availability compared to the obsolete DS3680DR.

Both components share identical ECCN and HTSUS classifications, maintaining export and tariff compliance consistency.

Frequently Asked Questions (FAQ)

Q: Why is the DS3680DR listed as obsolete? A: The DS3680DR has reached end-of-life status with Texas Instruments. Continued sourcing is limited to existing inventory. The AD9888KSZ-170 is the designated active alternative for new designs and ongoing production requirements.

Q: What is the primary difference between DS3680DR and AD9888KSZ-170? A: The primary difference is the package format. The DS3680DR uses a 14-SOIC package, while the AD9888KSZ-170 uses a 128-MQFP package. This requires PCB layout and schematic modifications for implementation.

Q: Are both components RoHS compliant? A: Yes. Both the DS3680DR and AD9888KSZ-170 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity difference between these parts? A: The DS3680DR has MSL 1 (Unlimited), while the AD9888KSZ-170 has MSL 3 (168 Hours). MSL 3 requires controlled storage conditions and has a 168-hour floor life after moisture exposure.

Q: Can I use AD9888KSZ-170 as a direct pin-for-pin replacement? A: No. The AD9888KSZ-170 is not a pin-for-pin replacement due to different package formats and pin counts. Circuit redesign and PCB layout modifications are required.

Q: What certifications apply to both components? A: Both components share EAR99 ECCN classification and 8542.39.0001 HTSUS code, maintaining consistent export and tariff treatment.
