MTFC4GLMDQ-AIT Z Equivalent & Substitute Parts

Part Overview

The MTFC4GLMDQ-AIT Z is a 32Gbit NAND Flash memory IC in MMC interface format, manufactured by Micron Technology Inc. and packaged in a 100-LBGA (14x18) configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

The primary reason for identifying substitute parts is the obsolete product status of the MTFC4GLMDQ-AIT Z. Active equivalent models ensure design continuity and supply chain reliability for applications requiring this memory specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTFC4GLMDQ-AIT Z is determined by strict equivalence across the following parameters:

• Memory Size: 32Gbit (exact match required)
• Memory Organization: 4G x 8 (exact match required)
• Memory Interface: MMC (exact match required)
• Package / Case: 100-LBGA (14x18) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (TA) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

The MTFC4GLMDQ-AIT A meets all substitution criteria and is classified as an active product, providing a direct functional replacement for the obsolete MTFC4GLMDQ-AIT Z.

Parameter Comparison

Engineering Selection Recommendations

The MTFC4GLMDQ-AIT A is the direct equivalent for the obsolete MTFC4GLMDQ-AIT Z. Both components are manufactured by Micron Technology Inc. and share identical electrical and mechanical specifications across all critical parameters: 32Gbit capacity, MMC interface, 100-LBGA packaging, and operating temperature range of -40°C to 85°C.

The MTFC4GLMDQ-AIT A carries active product status, ensuring ongoing availability and manufacturer support. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming compatibility for applications requiring environmental and regulatory adherence.

The supply voltage specification (2.7V ~ 3.6V) is documented for the MTFC4GLMDQ-AIT A. This parameter was not specified for the obsolete variant but represents the standard operating range for this memory class and should be applied to both parts in system design.

Frequently Asked Questions (FAQ)

Q: Can the MTFC4GLMDQ-AIT A directly replace the MTFC4GLMDQ-AIT Z in existing designs?

A: Yes. Both parts are identical in memory capacity (32Gbit), memory organization (4G x 8), interface type (MMC), package format (100-LBGA 14x18), and operating temperature range (-40°C to 85°C). No design modifications are required.

Q: What is the significance of the product status difference?

A: The MTFC4GLMDQ-AIT Z is classified as obsolete, indicating discontinued manufacturing and limited availability. The MTFC4GLMDQ-AIT A is active, ensuring reliable supply chain access and manufacturer technical support for new procurements and system updates.

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

A: No. Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level ratings (MSL 3, 168 Hours). Environmental and regulatory requirements are equivalent.

Q: Does the 100-LBGA (14x18) package format have any special handling requirements?

A: The Moisture Sensitivity Level 3 rating applies to both parts, requiring storage and handling protocols consistent with MSL 3 specifications (168-hour floor life after moisture exposure). Standard surface mount assembly procedures for BGA components apply.

Q: Is the supply voltage specification critical for substitution?

A: The MTFC4GLMDQ-AIT A operates at 2.7V to 3.6V. This specification should be applied to system designs using either part. Verify that existing power supply designs accommodate this voltage range.
