Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7130LA35TFG is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory type, format, size, and organization (8Kbit dual-port asynchronous SRAM, 1K x 8)
• Memory interface (parallel)
• Supply voltage range (4.5V ~ 5.5V)
• Package type (64-TQFP)
• Mounting type (surface mount)
• RoHS3 compliance

Performance Consideration:

• Access time must be equal to or faster than the original 35 ns specification

Temperature Range Consideration:

• Operating temperature range may vary; substitutes with extended temperature ranges (-40°C ~ 85°C) are functionally compatible but represent enhanced specifications

Package Dimensions:

• 64-TQFP packages are available in two footprint sizes: 10x10 mm and 14x14 mm; these are mechanically distinct and require PCB layout verification

The substitute parts listed below maintain electrical compatibility while offering improved access time performance (20 ns or 25 ns) and varying package dimensions and temperature ratings.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Footprint): The 7130LA20TFG is the primary substitute for the 7130LA35TFG. Both use 64-TQFP (10x10) packaging, enabling direct PCB substitution without layout modification. The 7130LA20TFG offers improved 20 ns access time performance and maintains active product status, ensuring long-term availability.

For Extended Temperature Range Applications: The 7130LA25TFGI provides the same 64-TQFP (10x10) footprint as the original part while extending the operating temperature range to -40°C ~ 85°C. Access time is 25 ns, which remains faster than the original 35 ns specification.

For Alternative Footprint Designs: Parts with 64-TQFP (14x14) packaging (7130LA20PFG, 7130LA25PFGI, 7140LA25PFG) are electrically equivalent but require PCB layout verification due to different package dimensions. These options are suitable for new designs or redesigns where footprint flexibility exists.

Compliance and Availability: All substitute parts maintain ROHS3 compliance and RoHS certification status. Active product status ensures continued manufacturing and supply chain availability, contrasting with the Last Time Buy status of the original 7130LA35TFG.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA20TFG directly replace the 7130LA35TFG on an existing PCB? A: Yes. Both parts use 64-TQFP (10x10) packaging with identical footprints. The 7130LA20TFG is electrically compatible and offers faster 20 ns access time, making it a direct substitute without PCB modification.

Q: What is the difference between 64-TQFP (10x10) and 64-TQFP (14x14) packages? A: These are different physical package sizes. The 10x10 mm package is smaller and requires a corresponding PCB footprint. The 14x14 mm package is larger. Parts are not interchangeable without PCB redesign.

Q: Are the substitute parts backward compatible with the original design? A: Yes, all substitute parts maintain the same electrical specifications: 8Kbit dual-port asynchronous SRAM, 1K x 8 organization, parallel interface, and 4.5V ~ 5.5V supply voltage. Faster access times (20 ns or 25 ns) are compatible with designs specified for 35 ns operation.

Q: Why should I select an active product over the Last Time Buy 7130LA35TFG? A: Active products ensure continued manufacturing, supply availability, and long-term support. Last Time Buy components have limited stock and no future production, creating supply chain risk for ongoing production or field replacement needs.

Q: Do the substitute parts with extended temperature range (-40°C ~ 85°C) work in standard 0°C ~ 70°C applications? A: Yes. Extended temperature range parts are fully compatible with standard temperature applications. They represent enhanced specifications and can be used as direct substitutes in any application within the standard temperature range.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory compliance of the original 7130LA35TFG.
