Engineering Selection Recommendations

For Direct Replacement (Standard Temperature Range 0°C ~ 70°C):

The 6116SA25SOG8 and 6116LA25SOG8 provide the closest performance match to the 6116SA35SOG8 with 25 ns access time. Both are active products with RoHS3 compliance. The 6116LA25SOG8 offers higher inventory availability (2587 Pcs) and is recommended for new designs requiring standard temperature operation.

For Extended Temperature Applications (-40°C ~ 85°C):

The 6116LA20SOGI8 and 6116LA25SOGI8 extend the operating temperature range to -40°C ~ 85°C. These parts are active products with RoHS3 compliance. Selection between these depends on timing requirements: 6116LA20SOGI8 for 20 ns access time or 6116LA25SOGI8 for 25 ns access time.

For Performance-Critical Applications:

The 6116SA15SOG8 provides the fastest access time at 15 ns while maintaining standard temperature range operation and active product status with RoHS3 compliance.

All substitute parts share identical electrical supply voltage (4.5V ~ 5.5V), memory capacity (16Kbit), organization (2K x 8), and 24-SOIC packaging, ensuring direct functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 6116SA35SOG8 be replaced with any of the listed substitute parts?

A: Yes, all listed parts maintain identical memory capacity (16Kbit), organization (2K x 8), parallel interface, supply voltage (4.5V ~ 5.5V), and 24-SOIC packaging. Substitution is electrically and mechanically compatible. Selection depends on required access time and operating temperature range.

Q: What is the difference between 6116SA and 6116LA series parts?

A: Both series are 16Kbit asynchronous SRAM with identical memory organization and packaging. The primary difference is access time specification and temperature range variants. The LA series offers additional temperature-extended options (SOGI8 suffix).

Q: Why do some parts have "SOGI8" suffix while others have "SOG8"?

A: The "I" in SOGI8 indicates extended industrial temperature range (-40°C ~ 85°C), while SOG8 indicates standard commercial temperature range (0°C ~ 70°C). Both use identical 24-SOIC packaging and are mechanically interchangeable.

Q: Is the 6116SA35SOG8 still available for purchase?

A: The 6116SA35SOG8 is classified as obsolete. However, 776 Pcs are currently in stock. For new designs and long-term availability, active substitute parts such as 6116LA25SOG8 (2587 Pcs available) are recommended.

Q: What are the RoHS compliance differences?

A: The main part (6116SA35SOG8) has REACH Unaffected status. All substitute parts are RoHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Can I use a faster access time part as a substitute?

A: Yes. Parts with faster access times (lower ns values) are functionally compatible. The 6116SA15SOG8 (15 ns), 6116LA20SOG8 (20 ns), and 6116LA20SOGI8 (20 ns) all provide faster performance than the original 35 ns specification and are direct substitutes.
