Equivalent & Substitute Parts for 71024S12TYGI8

Part Overview

The 71024S12TYGI8 is a 1Mbit asynchronous SRAM manufactured by Renesas Electronics Corporation in a 32-SOJ surface mount package. This volatile memory IC operates with a 12 ns access time and write cycle time, supporting parallel data interfaces across 128K x 8 memory organization. The part is actively produced and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same memory category and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 71024S12TYGI8 are qualified based on the following criteria:

Critical Parameters for Substitution:

• Memory capacity: 1Mbit
• Memory organization: 128K x 8
• Memory interface: Parallel
• Package footprint: 32-BSOJ (0.300", 7.62mm Width)
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount
• RoHS3 compliance
• MSL rating: 3 (168 Hours)

Acceptable Variation:

• Access time and write cycle time may be equal to or faster than the main part specification (12 ns or lower)

Two substitute parts meet these criteria: the 71024S15TYGI8 from Renesas Electronics Corporation and the IS61C1024AL-12JLI from ISSI (Integrated Silicon Solution Inc).

Parameter Comparison

Engineering Selection Recommendations

71024S15TYGI8 (Renesas Electronics Corporation)

This substitute maintains identical electrical and mechanical specifications to the main part with the exception of access time and write cycle time, which are specified at 15 ns versus 12 ns. Both parts are manufactured by Renesas Electronics Corporation and carry identical RoHS3 compliance and MSL ratings. Selection of this part is appropriate for applications where the 15 ns timing specification meets system requirements. Current inventory availability is 1111 units.

IS61C1024AL-12JLI (ISSI, Integrated Silicon Solution Inc)

This substitute provides equivalent access time and write cycle time specifications (12 ns) to the main part while maintaining all other electrical and mechanical parameters. The part is manufactured by ISSI and carries identical RoHS3 compliance and MSL ratings. The package footprint and mounting type are identical. Selection of this part is appropriate for applications requiring equivalent timing performance from an alternative manufacturer. Current inventory availability is 8097 units.

Frequently Asked Questions (FAQ)

Q: Can the 71024S15TYGI8 be used as a direct replacement for the 71024S12TYGI8?

A: The 71024S15TYGI8 is mechanically and electrically compatible with identical package footprint, supply voltage, operating temperature range, and memory organization. The primary difference is the access time and write cycle time specification of 15 ns versus 12 ns. Substitution is valid only if the application timing requirements accommodate the slower access time.

Q: What is the difference between the two substitute parts?

A: The 71024S15TYGI8 is a Renesas part with 15 ns timing. The IS61C1024AL-12JLI is an ISSI part with 12 ns timing matching the original specification. Both maintain identical package footprint, voltage, temperature range, and memory organization. Selection depends on timing requirements and manufacturer preference.

Q: Are all three parts pin-compatible?

A: All three parts use the 32-BSOJ (0.300", 7.62mm Width) package with identical mounting type (Surface Mount). Pin compatibility is confirmed for PCB layout purposes.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The main part 71024S12TYGI8 and both substitute parts 71024S15TYGI8 and IS61C1024AL-12JLI are ROHS3 compliant with MSL rating 3 (168 Hours).

Q: Which substitute part should be selected for timing-critical applications?

A: The IS61C1024AL-12JLI maintains the 12 ns access time and write cycle time specification identical to the main part 71024S12TYGI8, making it the appropriate selection for applications with strict timing requirements.
