Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT28C010-15TC is determined by strict equivalence across the following parameters: memory capacity (1Mbit), memory organization (128K x 8), parallel interface architecture, access time (150 ns), write cycle time (10ms), supply voltage range (4.5V ~ 5.5V), and physical package specification (32-TFSOP surface mount). The AT28C010-15TU qualifies as a direct substitute based on identical electrical specifications and package form factor. Differences in operating temperature range and product status do not affect functional substitutability for applications within the specified temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

The AT28C010-15TU is the direct functional equivalent for the obsolete AT28C010-15TC. Selection between these parts should be based on the following criteria:

The AT28C010-15TU is recommended for new designs and ongoing production due to active product status and ROHS3 compliance. This part maintains identical electrical performance and package compatibility while offering an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), providing greater flexibility for diverse application environments.

The AT28C010-15TC may be retained for legacy system maintenance only where existing inventory is available and temperature operating conditions remain within the 0°C to 70°C specification. RoHS non-compliance status should be evaluated against applicable regulatory requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can AT28C010-15TU directly replace AT28C010-15TC in existing designs?

A: Yes. Both parts share identical memory capacity (1Mbit), organization (128K x 8), parallel interface, access time (150 ns), write cycle time (10ms), supply voltage (4.5V ~ 5.5V), and 32-TFSOP package dimensions. Electrical and mechanical compatibility is complete.

Q: What is the difference in operating temperature range?

A: The AT28C010-15TC operates from 0°C to 70°C, while the AT28C010-15TU operates from -40°C to 85°C. For applications within the 0°C to 70°C window, both parts perform identically. The extended range of the AT28C010-15TU provides additional margin for industrial or extreme environment applications.

Q: Does the RoHS compliance difference affect substitutability?

A: RoHS compliance status does not affect electrical or mechanical substitutability. The AT28C010-15TU (ROHS3 compliant) is preferred for new designs and applications subject to RoHS regulations. The AT28C010-15TC (RoHS non-compliant) may be used only where regulatory exemptions apply or in legacy systems.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 32-TFSOP surface mount packaging with 0.724" width (18.40mm). PCB footprints and assembly processes are interchangeable.

Q: Why is the AT28C010-15TC classified as obsolete?

A: Obsolescence reflects Microchip Technology's product lifecycle status. The AT28C010-15TU remains in active production and is the recommended path forward for component sourcing.
