Substitute Part Grouping Explanation

Substitution of the 7130LA55PFI8 is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (8Kbit, 1K x 8)
• Dual-port asynchronous SRAM technology
• Parallel memory interface
• 64-TQFP package footprint and pinout compatibility
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)

The 7130LA25PFGI8 qualifies as a direct substitute based on identical memory specifications, package configuration, and electrical operating parameters. The primary distinction is improved access time performance (25 ns versus 55 ns), which represents a performance upgrade rather than a functional incompatibility. Both parts share the same base product number (7130LA) and are manufactured by Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

The 7130LA25PFGI8 is the qualified substitute for the obsolete 7130LA55PFI8. Selection of the substitute part is supported by the following factors:

• Functional equivalence across all memory specifications and electrical parameters
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance status, addressing regulatory requirements for new designs and manufacturing processes
• Improved access time performance (25 ns) provides timing margin for system operation
• Identical package footprint and pinout enable direct board-level replacement without layout modification
• Maintained supply voltage and temperature operating ranges ensure compatibility with existing system designs

Frequently Asked Questions (FAQ)

Q: Can the 7130LA25PFGI8 be used as a direct replacement for the 7130LA55PFI8 on existing circuit boards?

A: Yes. Both parts share identical package geometry (64-TQFP), pinout configuration, and electrical operating parameters. The substitute part can be soldered into existing PCB footprints without modification.

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

A: The 7130LA25PFGI8 features 25 ns access time compared to 55 ns for the 7130LA55PFI8. This represents faster memory response. Systems designed for the 55 ns part will operate correctly with the faster 25 ns substitute, as timing requirements are met or exceeded.

Q: Why is the 7130LA55PFI8 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Renesas Electronics Corporation. The 7130LA25PFGI8 remains in active production and serves as the current equivalent offering.

Q: Are there packaging differences between these parts?

A: The 7130LA55PFI8 is supplied in bulk packaging, while the 7130LA25PFGI8 is available in Tape & Reel (TR) format. Both contain identical die and functionality; packaging format reflects current manufacturing and distribution standards.

Q: Does RoHS compliance affect functional compatibility?

A: No. RoHS compliance status reflects manufacturing process and material composition standards. The ROHS3 compliance of the 7130LA25PFGI8 indicates adherence to current environmental and regulatory requirements without altering electrical or functional characteristics.
