Engineering Selection Recommendations

The 7132LA20JG is the direct functional equivalent of the 7132LA20J. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status and regulatory compliance. The 7132LA20J is obsolete and RoHS non-compliant, while the 7132LA20JG is active in production and ROHS3 compliant. For new designs or systems requiring regulatory compliance documentation, the 7132LA20JG is the appropriate selection. For legacy system maintenance where the original part specification must be maintained, the 7132LA20JG provides full functional compatibility as a direct replacement.

Frequently Asked Questions (FAQ)

Q: Can the 7132LA20JG be used as a direct replacement for the 7132LA20J?

A: Yes. Both parts are identical in memory capacity (16Kbit), organization (2K x 8), access time (20 ns), supply voltage (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 52-PLCC package configuration. The 7132LA20JG is manufactured by the same supplier and provides full functional compatibility.

Q: What is the difference between these two part numbers?

A: The 7132LA20J is obsolete and RoHS non-compliant. The 7132LA20JG is currently in active production and ROHS3 compliant. The electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 52-PLCC (J-Lead) surface mount package with identical pinout and mechanical dimensions (19.13x19.13 mm).

Q: What is the MSL rating for these parts?

A: Both parts carry an MSL rating of 3 with a 168-hour floor life. Proper moisture control during storage and handling is required per IPC standards.

Q: Can these parts be used interchangeably in existing PCB assemblies?

A: Yes. The 7132LA20JG is a direct pin-for-pin and functionally equivalent replacement for the 7132LA20J. No PCB modifications or design changes are required.
