Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71024S15TYG8 is determined by the following critical parameters:

• Memory capacity and organization (1Mbit, 128K x 8 configuration)
• Parallel interface architecture
• Package compatibility (32-SOJ form factor)
• Supply voltage range (4.5V ~ 5.5V)
• Access time equal to or faster than 15 ns
• Surface mount technology
• ROHS3 compliance

The identified substitute parts maintain these core electrical and mechanical specifications. Variations in operating temperature range and access time represent performance enhancements or extended operational capability rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance. The 71024S15TYGI8 is a direct Renesas equivalent with identical electrical specifications and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). The IS61C1024AL-12JLI from ISSI provides faster access time (12 ns) and write cycle time (12 ns) with equivalent extended temperature range, representing a performance-enhanced alternative. Package, mounting type, and supply voltage specifications are identical across all three parts, ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the 71024S15TYGI8 directly replace the 71024S15TYG8?

A: Yes. Both parts are manufactured by Renesas Electronics, share identical memory capacity (1Mbit), organization (128K x 8), access time (15 ns), supply voltage (4.5V ~ 5.5V), and 32-SOJ package specifications. The 71024S15TYGI8 extends the operating temperature range to -40°C ~ 85°C.

Q: Is the IS61C1024AL-12JLI compatible with applications designed for the 71024S15TYG8?

A: Yes, within the specified electrical and mechanical parameters. The IS61C1024AL-12JLI maintains 1Mbit capacity, 128K x 8 organization, 4.5V ~ 5.5V supply voltage, and 32-SOJ package compatibility. The 12 ns access time is faster than the original 15 ns specification, and the extended temperature range (-40°C ~ 85°C) accommodates broader operational environments.

Q: What are the key differences between these substitute parts?

A: The primary differences are manufacturer (Renesas versus ISSI), access time (15 ns for Renesas parts versus 12 ns for ISSI), and operating temperature range (0°C ~ 70°C for the original 71024S15TYG8 versus -40°C ~ 85°C for both substitutes). All other electrical and mechanical parameters remain constant.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 71024S15TYG8, 71024S15TYGI8, and IS61C1024AL-12JLI are all ROHS3 compliant with MSL rating 3 (168 Hours).

Q: Does faster access time affect compatibility?

A: No. Faster access time (12 ns) is backward compatible with designs specified for 15 ns access time. The IS61C1024AL-12JLI will function correctly in any application designed for the 71024S15TYG8.
