Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2149QN+ is determined by strict alignment across the following critical parameters:

• Functional Classification: Interface IC, specifically T1/J1 Line Interface Unit (LIU)
• Voltage Specification: 5V operation
• Package Type: 28-pin PLCC
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
• Product Status: Active manufacturing status
• Moisture Sensitivity: MSL 3 (168 Hours)

Only components matching all these parameters across electrical, mechanical, and regulatory dimensions qualify as direct substitutes. The DS2149QN+ serves as both the primary reference part and its own direct equivalent, indicating no alternative part numbers are available within the specified substitution criteria.

• Established supply chain with documented inventory levels (963 Pcs New Original In Stock)
• Standardized 28-pin PLCC package ensuring consistent PCB integration
• MSL 3 rating appropriate for standard manufacturing and storage conditions

For applications requiring component substitution, the DS2149QN+ represents the direct and only equivalent meeting all specified electrical, mechanical, and regulatory parameters.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DS2149QN+?

A: A valid substitute must match all critical parameters: Interface IC category, T1/J1 LIU functionality, 5V operation, 28-pin PLCC package, ROHS3 compliance, REACH unaffected status, and Active product status. Deviation in any parameter disqualifies substitution eligibility.

Q: Is the DS2149QN+ available in alternative package types?

A: The DS2149QN+ is specified exclusively in 28-pin PLCC packaging. Alternative package configurations would constitute different part numbers and fall outside direct substitution scope.

Q: What is the significance of MSL 3 (168 Hours) for this component?

A: MSL 3 indicates the component can remain in ambient conditions (typically 30°C/60% RH) for up to 168 hours before requiring baking prior to reflow soldering. This rating is standard for most telecommunications interface ICs and does not restrict substitution eligibility.

Q: Does ROHS3 compliance affect substitution options?

A: ROHS3 compliance is a mandatory parameter for substitution. Only components with identical ROHS3 compliance status qualify as direct substitutes. This ensures regulatory consistency across the bill of materials.

Q: Can the DS2149QN+ be substituted with earlier product revisions?

A: Substitution is limited to components with Active product status. Obsolete or discontinued revisions do not qualify as valid substitutes regardless of functional similarity.

Q: What is the ECCN classification significance?

A: The EAR99 ECCN classification indicates the DS2149QN+ is subject to standard export control regulations. Substitute parts must maintain identical ECCN classification to ensure compliance with international trade requirements.
