Substitute Part Grouping Explanation

Substitution eligibility for the 7005S35G is determined by strict equivalence across the following parameters:

• Memory capacity: 64Kbit
• Organization: 8K x 8 configuration
• Technology: Dual-port asynchronous SRAM
• Access and write cycle timing: 35 ns
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Package: 68-BPGA through-hole mounting
• Parallel interface architecture

The 7005L35G meets all substitution criteria. The primary distinction is product status: the 7005S35G is obsolete while the 7005L35G maintains active status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The 7005L35G is the direct substitute for the 7005S35G. Selection is based on the following factors:

• Electrical equivalence: Identical memory capacity, timing specifications, voltage requirements, and temperature range
• Mechanical compatibility: Identical 68-BPGA package footprint and through-hole mounting configuration
• Product lifecycle: The 7005L35G maintains active manufacturing status, ensuring supply chain continuity
• Regulatory alignment: Both parts share identical RoHS, REACH, and ECCN classifications
• Manufacturer designation: The 7005L35G is the manufacturer-recommended equivalent

For applications currently using the 7005S35G, direct substitution with the 7005L35G requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can the 7005L35G replace the 7005S35G in existing designs?
