Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTFC4GACAJCN-4M IT is determined by strict alignment across the following critical parameters:

• Memory capacity: 32Gbit
• Memory organization: 4G x 8 configuration
• Interface standard: MMC protocol compliance
• Package footprint: 153-VFBGA (11.5x13) physical dimensions
• Electrical specifications: 2.7V to 3.6V supply voltage range
• Temperature rating: -40°C to 85°C operational envelope
• Compliance certifications: ROHS3 and REACH status

The ASFC4G31M-51BIN from Alliance Memory, Inc. meets all specified substitution criteria, maintaining identical memory capacity, organization, interface protocol, package dimensions, voltage specifications, and temperature range. Both components share equivalent RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

The ASFC4G31M-51BIN qualifies as a direct functional equivalent to the MTFC4GACAJCN-4M IT based on matching electrical, mechanical, and compliance specifications. The substitute part maintains active product status, ensuring continued availability and supply chain reliability. Both components satisfy ROHS3 compliance requirements and carry identical MSL ratings, supporting equivalent handling and storage protocols. The transition from the obsolete MTFC4GACAJCN-4M IT to the active ASFC4G31M-51BIN presents no electrical or mechanical compatibility constraints for MMC-based applications operating within the specified voltage and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the ASFC4G31M-51BIN directly replace the MTFC4GACAJCN-4M IT in existing designs?

A: Yes. Both components share identical memory capacity (32Gbit), organization (4G x 8), MMC interface protocol, package dimensions (153-VFBGA/FBGA 11.5x13), supply voltage range (2.7V–3.6V), and operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: What is the primary reason for seeking a substitute?

A: The MTFC4GACAJCN-4M IT is classified as obsolete. The ASFC4G31M-51BIN maintains active product status, ensuring long-term availability and supply continuity.

Q: Are there differences in package designation between the two parts?

A: The main part uses 153-VFBGA designation while the substitute uses 153-FBGA. Both reference identical physical dimensions (11.5x13mm) and are mechanically and electrically compatible for surface mount applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MTFC4GACAJCN-4M IT and ASFC4G31M-51BIN are ROHS3 compliant and REACH unaffected, with matching MSL ratings of 3 (168 Hours).

Q: What are the key parameters that determine substitution eligibility?

A: Memory capacity, memory organization, interface protocol (MMC), package footprint, voltage specifications, temperature range, and compliance certifications must align exactly. All specified parameters match between these two components.
