Engineering Selection Recommendations

The 7130LA55JG8/2930 is the direct functional equivalent of the 7130LA55J8/2930. Both parts share identical electrical and mechanical specifications, ensuring drop-in compatibility in existing designs.

The primary distinction is product lifecycle status: the original part is obsolete, while the substitute is active production. Additionally, the substitute part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new manufacturing and procurement.

For applications requiring the 8Kbit dual-port parallel SRAM architecture with 55 ns timing in a 52-PLCC package, the 7130LA55JG8/2930 provides continuity of supply and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-for-pin compatible? A: Yes. Both the 7130LA55J8/2930 and 7130LA55JG8/2930 use the 52-PLCC J-Lead package with identical pinout and electrical characteristics.

Q: What is the difference between these part numbers? A: The parts are functionally equivalent. The primary differences are product status (obsolete versus active) and RoHS compliance certification (non-compliant versus ROHS3 compliant).

Q: Can I use the substitute in new designs? A: Yes. The 7130LA55JG8/2930 is an active production part with ROHS3 compliance, making it suitable for new designs requiring 8Kbit dual-port asynchronous SRAM with 55 ns access time.

Q: Are the timing specifications identical? A: Yes. Both parts specify 55 ns access time and 55 ns write cycle time, with identical voltage supply ranges (4.5V ~ 5.5V) and operating temperature ranges (0°C ~ 70°C).

Q: What is the package configuration? A: Both parts use a 52-PLCC (J-Lead) surface-mount package with dimensions of 19.13 x 19.13 mm.

Q: Does RoHS compliance affect functionality? A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. The substitute part maintains full functional equivalence while meeting modern regulatory requirements.
