Substitute Part Grouping Explanation

Substitute parts are identified strictly based on matching manufacturer, category (Memory), technology (EEPROM), memory format (EEPROM), memory interface (Parallel), supply voltage (4.5V ~ 5.5V), access time (150 ns), mounting type (Surface Mount), package (28-SOIC), and compliance attributes. Compatibility is established by ensuring these parameters are equivalent or permitted in substitutions within the EEPROM category. Memory size and organization may vary, but core mechanical and electrical parameters are matched for substitution validity.

Key Parameters for Substitution:

• Manufacturer: Microchip Technology
• Category: Memory
• Memory Type: Non-Volatile
• Memory Format: EEPROM
• Technology: EEPROM
• Memory Interface: Parallel
• Voltage – Supply: 4.5V ~ 5.5V
• Access Time: 150 ns
• Mounting Type: Surface Mount
• Package / Case: 28-SOIC (0.295", 7.50mm Width)
• Supplier Device Package: 28-SOIC

Parameter Comparison

Engineering Selection Recommendations

The AT28C17E-15SC is obsolete and RoHS non-compliant. The substitute part AT28C64B-15SU from the same manufacturer is available, active, and is ROHS3 compliant. Both share essential mechanical and electrical parameters, including supply voltage, access time, package, and mounting type. The substitute part also maintains the same regulatory codes (ECCN, HTSUS) and category, ensuring compatibility under current compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What primary factors determine substitute compatibility for EEPROM memory ICs?
Compatibility is determined by manufacturer, memory format, memory technology, interface type, package/case, supply voltage range, and access time.

Q2: Does the package of AT28C64B-15SU match AT28C17E-15SC?
Both ICs have a 28-SOIC (0.295", 7.50mm Width) package and are suitable for surface mount applications.

Q3: Can different memory organizations affect substitution?
Substitution within the EEPROM category allows for varied memory organization, provided critical mechanical and electrical specifications are maintained.

Q4: Are there differences in compliance between the main and substitute parts?
AT28C17E-15SC is RoHS non-compliant, while AT28C64B-15SU is ROHS3 compliant; both are REACH unaffected.

Q5: Is the operating temperature range the same?
AT28C64B-15SU supports a wider operating temperature range (-40°C ~ 85°C) compared to AT28C17E-15SC (0°C ~ 70°C).

Q6: Do substitute parts require modifications in PCB footprint?
Both parts share identical package dimensions and supplier device package, so no changes are needed for the PCB footprint.
