Substitute Part Grouping Explanation

Substitution of the 7134SA35CB is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute, Renesas 7134LA35CB, maintains identical specifications across memory capacity, organization, access timing, voltage supply range, operating temperature range, and physical package dimensions. Both parts are manufactured by Renesas Electronics Corporation and utilize the same 48-SIDE BRAZED package configuration.

The substitution is valid based on the following matching criteria:

• Memory capacity: 32Kbit
• Memory organization: 4K x 8
• Access time: 35 ns
• Write cycle time: 35 ns
• Supply voltage: 4.5V to 5.5V
• Temperature range: -55°C to 125°C
• Package: 48-DIP through-hole
• Interface: Parallel dual-port asynchronous

The key distinction between the main part and substitute is product status: the 7134SA35CB is obsolete, while the 7134LA35CB maintains active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations
