Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTFC128GAPALNS-AAT is determined by the following critical parameters:

• Memory capacity: 1Tbit (128G x 8 organization)
• Memory technology: FLASH - NAND
• Interface protocol: MMC or eMMC compatibility
• Package footprint: 153-TFBGA or 153-VFBGA (11.5x13 dimensions)
• Operating temperature range: -40°C ~ 105°C
• Compliance certifications: ROHS3 Compliant

The MTFC128GAZAQJP-AAT qualifies as a direct substitute based on matching memory capacity, NAND technology, identical operating temperature range, and compatible package dimensions. The primary distinction is the interface upgrade from MMC to eMMC, which represents an enhanced protocol version maintaining backward compatibility for equivalent electrical and mechanical integration.

Parameter Comparison

Engineering Selection Recommendations

The MTFC128GAZAQJP-AAT is the designated substitute for the obsolete MTFC128GAPALNS-AAT. Selection is supported by:

• Active product status with confirmed inventory availability (3200 pcs)
• Identical memory capacity and NAND technology
• Matching operating temperature specifications
• ROHS3 compliance certification maintained
• Equivalent MSL rating (3, 168 Hours)
• Same base product number (MTFC128) indicating common design lineage

The transition from MMC to eMMC interface represents a protocol enhancement within the same product family. Both interfaces operate within the same electrical and mechanical constraints for this application class.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting MTFC128GAPALNS-AAT?

A: The original part is classified as obsolete. The MTFC128GAZAQJP-AAT provides equivalent functionality with active manufacturing status and confirmed supply availability.

Q: Are the package dimensions identical between the main part and substitute?

A: Both parts use 11.5x13mm footprints. The main part uses 153-TFBGA packaging while the substitute uses 153-VFBGA packaging. These designations indicate minor variations in ball grid array configuration but maintain identical physical dimensions for PCB layout compatibility.

Q: What is the difference between MMC and eMMC interfaces?

A: eMMC is an enhanced version of the MMC interface protocol. Both are supported by the same electrical and mechanical specifications for this memory class. The substitute part's eMMC interface is compatible with systems designed for MMC operation.

Q: Are the supply voltage specifications identical?

A: The main part does not specify supply voltage in the provided data. The substitute part operates at 2.7V ~ 3.6V. Confirm system voltage compatibility before implementation.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant and carry identical MSL ratings (3, 168 Hours), ensuring equivalent handling and storage requirements.
