Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 71024S20TYG8 are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Memory Size: 1Mbit
• Memory Organization: 128K x 8
• Memory Interface: Parallel
• Voltage Supply: 4.5V ~ 5.5V
• Package / Case: 32-BSOJ (0.300", 7.62mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Performance Variation Parameters:

• Access Time: Equal to or faster than 20 ns
• Write Cycle Time: Equal to or faster than 20 ns
• Operating Temperature Range: May extend beyond 0°C ~ 70°C

All identified substitutes maintain identical memory capacity, organization, interface, electrical specifications, and physical packaging. Differences in access time and operating temperature represent performance enhancements or extended operational capability.

Parameter Comparison

Engineering Selection Recommendations

71024S15TYGI8 (Renesas Electronics)

This substitute provides faster access time (15 ns versus 20 ns) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). Both parts are manufactured by Renesas Electronics and maintain identical memory specifications, electrical ratings, and physical packaging. Selection of this part is appropriate when extended temperature operation or improved performance margin is required.

IS61C1024AL-12JLI (ISSI)

This substitute offers the fastest access time (12 ns) and extended operating temperature range (-40°C ~ 85°C). Manufactured by ISSI, this part maintains all electrical and mechanical compatibility requirements. Selection of this part is appropriate when maximum performance margin or extended temperature operation is required, with consideration for cross-manufacturer qualification in the target application.

Both substitutes are actively produced, ROHS3 compliant, and carry identical MSL ratings. Selection between substitutes depends on performance requirements, temperature range needs, and manufacturer qualification status within the application.

Frequently Asked Questions (FAQ)

Q: Can 71024S15TYGI8 or IS61C1024AL-12JLI be used as direct replacements for 71024S20TYG8?

A: Yes, both parts are direct substitutes. They maintain identical memory capacity (1Mbit), organization (128K x 8), parallel interface, voltage supply (4.5V ~ 5.5V), and 32-BSOJ package. The substitutes provide equal or faster access times and extended operating temperature ranges, making them functionally compatible in applications designed for the 71024S20TYG8.

Q: What is the difference in access time between these parts?

A: The 71024S20TYG8 has 20 ns access time. The 71024S15TYGI8 provides 15 ns access time, and the IS61C1024AL-12JLI provides 12 ns access time. Faster access times represent performance improvements and are backward compatible with designs requiring the original 20 ns specification.

Q: Are there operating temperature differences?

A: Yes. The 71024S20TYG8 operates from 0°C ~ 70°C. Both substitutes extend this range to -40°C ~ 85°C, providing operation in wider temperature environments. Applications limited to 0°C ~ 70°C can use any of the three parts without temperature-related constraints.

Q: Do all parts use the same package?

A: Yes. All three parts use the 32-BSOJ package (0.300", 7.62mm Width) with surface mount configuration. Pin-for-pin compatibility is maintained across all substitutes.

Q: Are there manufacturer differences?

A: The 71024S20TYG8 and 71024S15TYGI8 are manufactured by Renesas Electronics Corporation. The IS61C1024AL-12JLI is manufactured by ISSI (Integrated Silicon Solution Inc). Both manufacturers produce ROHS3 compliant parts with identical electrical and mechanical specifications for this memory category.

Q: What compliance certifications apply to all parts?

A: All three parts are ROHS3 compliant, carry MSL rating 3 (168 Hours), and are REACH unaffected. All parts are actively produced and available in new original condition.
