Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS26528GN+ is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 256-CSBGA (17x17) surface-mount package to ensure PCB layout and assembly compatibility.
• Supply Voltage Range: The substitute must operate within the 3.135V ~ 3.465V supply voltage specification.
• Operating Temperature Range: The substitute must support the -40°C ~ 85°C operating temperature range.
• Mounting Type: Surface mount configuration must be maintained.
• Compliance Standards: RoHS3 compliance and REACH unaffected status must be preserved.

The DS26518GN+ qualifies as a manufacturer-recommended substitute based on these parameters. While the DS26518GN+ features 8/8 drivers and receivers (compared to the 4/4 configuration of the DS26528GN+) and implements T1/E1/J1 protocol support, it maintains electrical and mechanical compatibility through identical package geometry, voltage specifications, temperature range, and compliance certifications.

Engineering Selection Recommendations

The DS26518GN+ is designated as the manufacturer-recommended substitute for the obsolete DS26528GN+. Selection of this substitute is supported by the following factors:

• Product Status: The DS26518GN+ maintains active product status, ensuring ongoing availability and manufacturing support compared to the obsolete DS26528GN+.
• Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.
• Electrical Specifications: Identical supply voltage range (3.135V ~ 3.465V) and operating temperature range (-40°C ~ 85°C) ensure functional compatibility in existing circuit designs.
• Package Geometry: Both parts utilize the 256-CSBGA (17x17) package, maintaining PCB footprint and assembly process compatibility.
• Moisture Sensitivity: The DS26518GN+ features improved moisture sensitivity (MSL 3 vs. MSL 4), providing enhanced reliability during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the DS26518GN+ be used as a direct replacement for the DS26528GN+ in existing designs?

A: The DS26518GN+ is electrically and mechanically compatible with the DS26528GN+ based on matching supply voltage, operating temperature range, and 256-CSBGA (17x17) package specifications. However, the DS26518GN+ provides 8/8 drivers and receivers versus the 4/4 configuration of the DS26528GN+. Design verification is necessary to confirm that the increased driver/receiver count does not introduce functional conflicts in the target application.

Q: What is the significance of the different protocols (IEEE 1149.1 vs. T1/E1/J1)?

A: The DS26528GN+ implements IEEE 1149.1 protocol, while the DS26518GN+ supports T1/E1/J1 protocol. These represent different transceiver protocol implementations. Compatibility depends on the specific protocol requirements of the application circuit.

Q: Are there differences in handling and storage between these parts?

A: The DS26518GN+ has a lower Moisture Sensitivity Level (MSL 3, 168 hours) compared to the DS26528GN+ (MSL 4, 72 hours). This indicates the DS26518GN+ can tolerate longer exposure to moisture before soldering, providing a wider processing window during assembly operations.

Q: Why is the DS26528GN+ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DS26518GN+ is recommended as the active alternative to ensure continued supply chain access and manufacturing support.

Q: Are the package designations "256-LBGA" and "256-BGA" equivalent?

A: Both designations refer to 256-pin Ball Grid Array packages. The supplier device package specification of 256-CSBGA (17x17) is identical for both parts, confirming physical and electrical compatibility at the PCB level.
