Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7134SA35P is based on strict equivalence across the following critical parameters:

• Memory capacity and organization (32Kbit, 4K x 8 configuration)
• Dual-port asynchronous SRAM technology
• Parallel interface architecture
• Access and write cycle timing (35 ns)
• Supply voltage compatibility (4.5V ~ 5.5V)
• Physical package form factor (48-DIP, 0.600" pitch)
• Through-hole mounting compatibility

The Renesas Electronics 7134LA35CB meets all these electrical and mechanical requirements, establishing it as a direct functional equivalent. Both parts share identical memory specifications, timing characteristics, and physical packaging, enabling pin-for-pin replacement in legacy circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The 7134LA35CB is the designated manufacturer-recommended substitute for the obsolete 7134SA35P. Both components are manufactured by Renesas Electronics Corporation and maintain identical electrical specifications and physical packaging.

The 7134LA35CB offers extended operational advantages: active product status ensures continued availability and manufacturing support, expanded operating temperature range (-55°C to 125°C versus 0°C to 70°C), and improved moisture sensitivity rating (MSL 1 versus MSL 3). These characteristics make the 7134LA35CB suitable for applications requiring broader environmental tolerance and long-term component sourcing stability.

Both parts carry RoHS non-compliant status and REACH unaffected classification. Component selection should be based on specific application temperature requirements and supply chain availability constraints.

Frequently Asked Questions (FAQ)

Q: Can the 7134LA35CB directly replace the 7134SA35P in existing circuit designs?

A: Yes. Both parts are pin-for-pin compatible with identical electrical specifications, memory organization, timing characteristics, and 48-DIP package form factor. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The 7134SA35P is obsolete, while the 7134LA35CB maintains active product status. The substitute offers extended operating temperature range (-55°C to 125°C) and superior moisture sensitivity rating (MSL 1 versus MSL 3), providing enhanced environmental tolerance and manufacturing availability.

Q: Are there any compliance or certification differences?

A: Both parts share identical RoHS non-compliant and REACH unaffected status. No compliance advantages exist between the two components.

Q: Does the expanded temperature range of the 7134LA35CB affect its use in standard applications?

A: No. The 7134LA35CB's extended temperature range (-55°C to 125°C) encompasses the original part's operating range (0°C to 70°C). Applications operating within the original temperature specification remain fully compatible.

Q: What packaging format is used for the 7134LA35CB?

A: The 7134LA35CB is supplied in 48-SIDE BRAZED package configuration, maintaining the same 48-DIP physical form factor (0.600", 15.24mm pitch) as the original 7134SA35P for through-hole mounting applications.
