Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7130SA25PF is determined by the following critical parameters:

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

The 7130LA20PFG qualifies as a direct substitute based on matching all core electrical and mechanical specifications. The primary distinction is improved access time performance (20 ns versus 25 ns), which represents a performance upgrade rather than a functional limitation.

Engineering Selection Recommendations

The 7130LA20PFG is the qualified substitute for the obsolete 7130SA25PF. Selection of the 7130LA20PFG provides the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance aligns with current environmental and regulatory requirements
• Improved access time (20 ns) and write cycle time (20 ns) provide performance headroom without functional compromise
• Identical package footprint, pinout, and electrical interface enable direct board-level replacement
• Maintained supply voltage and operating temperature specifications ensure system compatibility

No design modifications are required for substitution. The 7130LA20PFG operates within all electrical and thermal parameters of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA20PFG replace the 7130SA25PF in existing designs?

A: Yes. The 7130LA20PFG is electrically and mechanically compatible with the 7130SA25PF. Both parts share identical memory capacity, organization, interface type, package footprint, supply voltage range, and operating temperature range. No circuit modifications are required.

Q: What is the difference between the 7130SA25PF and 7130LA20PFG?

A: The primary differences are access time (25 ns versus 20 ns), write cycle time (25 ns versus 20 ns), product status (obsolete versus active), and RoHS compliance (non-compliant versus ROHS3 compliant). The 7130LA20PFG represents a performance upgrade with improved timing specifications.

Q: Are the packages identical?

A: Yes. Both parts use the 64-TQFP (14x14) package with surface mount configuration. Pinout and footprint are identical, enabling direct PCB replacement.

Q: Does the faster access time of the 7130LA20PFG affect system compatibility?

A: No. Faster access time is a performance improvement that maintains backward compatibility. Systems designed for 25 ns access time operate correctly with 20 ns components.

Q: What is the RoHS compliance status difference?

A: The 7130SA25PF is RoHS non-compliant. The 7130LA20PFG is ROHS3 compliant, meeting current environmental regulations for new designs and manufacturing.

Q: Is the 7130LA20PFG available in the same packaging options?

A: The 7130LA20PFG is supplied in Tray packaging. Both parts are surface mount components suitable for automated assembly processes.
