Equivalent & Substitute Parts for Renesas 7132SA35C

Part Overview

The Renesas 7132SA35C is a 16Kbit dual-port asynchronous SRAM with parallel interface, organized as 2K x 8, featuring 35 ns access time and 48-DIP through-hole packaging. This component is classified as obsolete, making substitute part identification essential for system redesign, legacy equipment maintenance, and production continuity. The part operates within a 4.5V to 5.5V supply range and is rated for 0°C to 70°C operating temperature.

Substitute Part Grouping Explanation

Substitution eligibility for the 7132SA35C is determined by the following critical parameters:

Memory capacity and organization (16Kbit, 2K x 8 configuration)
Dual-port asynchronous SRAM technology
Parallel interface architecture
48-DIP through-hole package compatibility
Supply voltage range (4.5V ~ 5.5V)
Access time performance requirements

The Renesas 7132LA100CB qualifies as a functional substitute based on matching memory capacity, organization, technology, interface type, and package form factor. The primary distinction is access time specification: the substitute operates at 100 ns versus the original 35 ns specification, with an extended operating temperature range of -55°C to 125°C.

Engineering Selection Recommendations

The 7132LA100CB is available as an active product from Renesas Electronics Corporation, providing supply continuity for applications requiring 16Kbit dual-port asynchronous SRAM in 48-DIP packaging. Both parts maintain identical supply voltage specifications and package form factors, enabling direct socket replacement in through-hole applications.

The substitute part operates at 100 ns access time compared to the original 35 ns specification. System designs must verify that timing margins accommodate this performance difference. The extended operating temperature range of -55°C to 125°C in the substitute part provides broader environmental coverage than the original 0°C to 70°C specification.

Both parts carry RoHS non-compliant status and are unaffected by REACH regulations. Compliance requirements for new designs should be evaluated independently.

Frequently Asked Questions (FAQ)

Q: Can the 7132LA100CB directly replace the 7132SA35C in existing circuit boards?

A: Physical and electrical compatibility is confirmed. Both parts use identical 48-DIP through-hole packaging and 4.5V to 5.5V supply voltage. However, the substitute operates at 100 ns access time versus 35 ns for the original. System timing analysis is required to confirm functional compatibility.

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

A: The 7132LA100CB has a slower access time (100 ns versus 35 ns) and an extended operating temperature range (-55°C to 125°C versus 0°C to 70°C). Both parts are identical in memory capacity, organization, interface type, and package form factor.

Q: Is the 7132LA100CB suitable for high-speed applications?

A: The 100 ns access time specification must be evaluated against system timing requirements. Applications designed for 35 ns performance may require timing margin verification before substitution.

Q: Are there any compliance differences between the original and substitute parts?

A: Both parts are RoHS non-compliant and REACH unaffected. Compliance status is identical between the two parts.

Q: What is the inventory status of the substitute part?

A: The 7132LA100CB is classified as an active product with current availability. The original 7132SA35C is obsolete.
