71024S12TYGI Equivalent & Substitute Parts

Part Overview

The 71024S12TYGI is a 1Mbit asynchronous SRAM memory IC manufactured by Renesas Electronics Corporation. This parallel interface memory device operates at 12 ns access time with 128K x 8 memory organization in a 32-SOJ surface mount package. The part is actively produced and ROHS3 compliant, serving applications requiring volatile parallel memory with standard 5V supply operation. Substitute parts are identified for inventory availability, extended lead times, or design flexibility while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

71024S12TYGI (Renesas Electronics Corporation) - Primary specification. 12 ns access and write cycle time. ROHS3 compliant. Active product status with 721 units in stock.

71024S15TYGI (Renesas Electronics Corporation) - Manufacturer-recommended substitute. Identical electrical and mechanical specifications except access time and write cycle time extended to 15 ns. ROHS3 compliant. Active product status with 2200 units in stock. Suitable for applications where 15 ns timing meets system requirements.

IS61C1024AL-12JLI (ISSI, Integrated Silicon Solution Inc) - Cross-manufacturer substitute. Matches 12 ns access and write cycle time performance of primary part. ROHS3 compliant. Active product status with 8097 units in stock. Packaging format is tray instead of tube. Suitable for applications requiring equivalent timing performance from alternative manufacturer source.

Frequently Asked Questions (FAQ)

Q: Can 71024S15TYGI replace 71024S12TYGI in all applications?

A: 71024S15TYGI is electrically and mechanically compatible with identical package, voltage, temperature range, and memory organization. The 15 ns access time is slower than the 12 ns specification. Substitution is valid only if system timing requirements accommodate 15 ns access time.

Q: What is the difference between tube and tray packaging for IS61C1024AL-12JLI?

A: Both packaging formats contain identical memory devices. Tube packaging is supplied in plastic tubes; tray packaging is supplied in plastic trays. Packaging format does not affect electrical performance or PCB mounting compatibility.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use 32-BSOJ (0.300", 7.62mm Width) surface mount package with identical pinout for 128K x 8 parallel SRAM interface.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant with MSL rating 3 (168 Hours) and REACH unaffected status.

Q: Which substitute part should be selected for new designs?

A: Selection depends on timing requirements and supply chain factors. For 12 ns timing requirement, IS61C1024AL-12JLI provides alternative manufacturer source. For applications tolerating 15 ns timing, 71024S15TYGI offers higher inventory availability from primary manufacturer.
