Equivalent & Substitute Parts for Renesas 7130SA55J8/C

Part Overview

The Renesas 7130SA55J8/C is an 8Kbit dual-port asynchronous SRAM with parallel interface, housed in a 52-PLCC package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The part operates within the 4.5V to 5.5V supply range with a 55 ns access time and is suitable for applications requiring volatile memory with parallel data access.

Substitute Part Grouping Explanation

Substitution of the 7130SA55J8/C is determined by strict equivalence across the following parameters:

• Memory capacity (8Kbit) and organization (1K x 8)
• Dual-port asynchronous SRAM architecture
• Parallel interface configuration
• 52-PLCC package footprint and pinout compatibility
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)

The 7130LA20JG qualifies as a direct substitute based on identical memory specifications, package type, and electrical operating parameters. The primary distinction is improved access time performance (20 ns versus 55 ns), which represents a performance enhancement rather than a functional limitation.

Parameter Comparison

Engineering Selection Recommendations

The 7130LA20JG is the appropriate substitute for the obsolete 7130SA55J8/C. Selection is justified on the following basis:

• Functional equivalence across all memory specifications and electrical parameters
• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance addresses regulatory requirements not met by the original part
• Identical package footprint and pinout enable direct board-level replacement
• Improved access time (20 ns) provides performance margin without introducing compatibility issues
• Matching MSL rating (3) maintains moisture sensitivity handling requirements

Frequently Asked Questions (FAQ)

Q: Can the 7130LA20JG be used as a direct replacement for the 7130SA55J8/C?

A: Yes. Both parts share identical memory capacity (8Kbit), organization (1K x 8), dual-port asynchronous architecture, parallel interface, 52-PLCC package footprint, and electrical operating parameters (4.5V ~ 5.5V supply, 0°C ~ 70°C operating range). The 7130LA20JG provides faster access time (20 ns versus 55 ns), which is compatible with timing-critical applications.

Q: Are there any pinout differences between these parts?

A: No. Both the 7130SA55J8/C and 7130LA20JG use the 52-PLCC package with identical pinout configuration, enabling direct board-level substitution without layout modifications.

Q: What is the significance of the access time difference?

A: The 7130LA20JG operates with 20 ns access time compared to 55 ns for the original part. This represents improved performance and does not introduce compatibility constraints. Systems designed for 55 ns operation will function correctly with the faster substitute.

Q: Does the RoHS compliance difference affect substitution?

A: The 7130LA20JG meets ROHS3 compliance while the 7130SA55J8/C does not. For applications subject to RoHS regulations, the substitute part satisfies compliance requirements. For legacy systems without RoHS mandates, both parts remain functionally equivalent.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts carry MSL rating 3 (168 Hours), requiring identical handling and storage protocols during manufacturing and assembly processes.
