Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the GS1528-CTAE3Z is determined by the following critical parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and electrical interface compatibility
• Function: Driver — functional role in video signal transmission
• Control Interface: Serial — communication protocol requirement
• Mounting Type: Surface Mount — PCB assembly compatibility
• Voltage - Supply: Operating voltage range must accommodate system requirements
• Standards Compliance: SMPTE and related video transmission standards

The M21218G-42 from MACOM Technology Solutions meets these substitution criteria. Both components share identical package specifications, surface mount configuration, serial control interface, and professional video application focus. The M21218G-42 supports both DVB-ASI and SMPTE standards, providing extended standard compatibility while maintaining the same 8-SOIC package footprint.

Parameter Comparison

Engineering Selection Recommendations

The M21218G-42 is the qualified substitute for the obsolete GS1528-CTAE3Z based on the following engineering criteria:

Product Status: The GS1528-CTAE3Z is obsolete, while the M21218G-42 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The M21218G-42 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in professional video applications.

Package Compatibility: Both components utilize identical 8-SOIC packaging with 0.154" (3.90mm) width, ensuring direct PCB footprint compatibility without layout modifications.

Functional Equivalence: Both components serve as video driver ICs with serial control interfaces for professional video applications. The M21218G-42 supports extended standards coverage (DVB-ASI and SMPTE) compared to the GS1528-CTAE3Z (SMPTE only).

Voltage Considerations: The M21218G-42 operates at 2.5V and 3.3V supply voltages. Systems designed for the GS1528-CTAE3Z operating range (3.135V ~ 3.465V) are compatible with the M21218G-42 at the 3.3V supply point.

Frequently Asked Questions (FAQ)

Q: Can the M21218G-42 directly replace the GS1528-CTAE3Z without PCB modifications?

A: Yes. Both components share identical 8-SOIC package specifications and surface mount configuration. Direct footprint compatibility is confirmed. No PCB layout changes are required.

Q: What is the voltage compatibility between these two components?

A: The GS1528-CTAE3Z operates at 3.135V ~ 3.465V. The M21218G-42 operates at 2.5V and 3.3V. The 3.3V operating point of the M21218G-42 falls within the upper range of the GS1528-CTAE3Z specification, ensuring functional compatibility in systems designed for the original component.

Q: Does the M21218G-42 support the same standards as the GS1528-CTAE3Z?

A: The M21218G-42 supports both DVB-ASI and SMPTE standards. The GS1528-CTAE3Z supports SMPTE. The M21218G-42 provides extended standard compatibility while maintaining full SMPTE support.

Q: What is the moisture sensitivity level for both components?

A: Both the GS1528-CTAE3Z and M21218G-42 have a Moisture Sensitivity Level (MSL) of 2 with a 1-year floor life rating. Identical handling and storage requirements apply.

Q: Is the M21218G-42 RoHS compliant?

A: Yes. The M21218G-42 is ROHS3 compliant. The GS1528-CTAE3Z RoHS status is not specified in the available documentation.

Q: Why is the GS1528-CTAE3Z classified as obsolete?

A: The GS1528-CTAE3Z is no longer in active production. The M21218G-42 is the recommended active substitute for new designs and ongoing system support.
