Key Parameters

Substitute Part Grouping Explanation

Substitution for the 6116SA35SOG is determined by the following critical parameters that must remain constant or be compatible:

Fixed Parameters (Must Match):

• Memory Size: 16Kbit
• Memory Organization: 2K x 8
• Memory Interface: Parallel
• Voltage Supply: 4.5V ~ 5.5V
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Variable Parameters (Substitution Allowed):

• Access Time: Can be equal to or faster than 35 ns
• Write Cycle Time: Can be equal to or faster than 35 ns
• Operating Temperature: Can be extended range (-40°C ~ 85°C) or standard range (0°C ~ 70°C)
• Manufacturer: Renesas Electronics Corporation or IDT (Integrated Device Technology Inc)
• Product Status: Active parts preferred over obsolete

All substitute parts listed maintain identical memory capacity, organization, interface, voltage specifications, and physical packaging, ensuring direct functional compatibility while offering improved performance characteristics or extended operating conditions.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Standard Temperature Range): The 6116LA25SOG offers the closest performance match to the 6116SA35SOG with a 25 ns access time and write cycle time, maintaining the 0°C ~ 70°C operating temperature range. This part is active, ROHS3 compliant, and available in volume. It provides improved performance while preserving thermal operating boundaries.

For Extended Temperature Applications: The 6116LA25SOGI or 6116SA25SOGI extend the operating temperature range to -40°C ~ 85°C while maintaining 25 ns timing specifications. These parts are suitable for industrial or automotive environments requiring wider temperature tolerance.

For Maximum Performance: The 6116LA20SOG and 6116LA20SOGI deliver 20 ns access and write cycle times, representing a 43% performance improvement over the original 6116SA35SOG. The 6116LA20SOGI variant includes extended temperature range capability.

For Fastest Operation: The 6116SA15SOG from IDT provides 15 ns access time, the fastest available option, suitable for performance-critical applications where timing margins are critical.

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a faster access time part as a substitute? A: Yes. Any substitute part with equal or faster access time and write cycle time than the original 35 ns specification is functionally compatible. Faster parts operate within the timing requirements of circuits designed for the 6116SA35SOG.

Q: What is the difference between SOG and SOGI package designations? A: Both are 24-SOIC packages with identical physical dimensions (0.295", 7.50mm width). The "I" suffix typically indicates extended temperature range capability (-40°C ~ 85°C) versus standard range (0°C ~ 70°C). Mechanical compatibility is identical.

Q: Are Renesas and IDT parts interchangeable? A: Yes, for the 6116 series. Both manufacturers produce functionally equivalent 16Kbit parallel SRAM devices with identical memory organization, interface, voltage specifications, and physical packaging. Electrical performance characteristics differ only in access time.

Q: Does using an extended temperature part affect my design? A: No. Extended temperature parts (-40°C ~ 85°C) are backward compatible with standard temperature applications (0°C ~ 70°C). They provide additional operational margin without design modification.

Q: What is the inventory status for these substitutes? A: All listed substitute parts are currently in stock as new original components, with quantities ranging from 826 to 1404 pieces, ensuring availability for production and repair applications.

Q: Is RoHS compliance important for my selection? A: Renesas parts (6116LA series) are ROHS3 compliant. IDT parts do not specify RoHS status. If RoHS compliance is a design requirement, select from the Renesas 6116LA family.
