Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7024L30J is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (64Kbit, 4K x 16 configuration)
• Dual-port asynchronous SRAM architecture
• Parallel memory interface
• 84-PLCC surface mount package with identical pinout
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)

The 7024L15JG qualifies as a direct substitute based on full compatibility across all mechanical and electrical parameters. The primary distinction is improved access time performance (15 ns versus 30 ns), which represents a performance upgrade rather than a functional limitation.

Parameter Comparison

Engineering Selection Recommendations

The 7024L15JG is the appropriate substitute for the obsolete 7024L30J based on the following factors:

Product Status: The 7024L30J is obsolete, while the 7024L15JG maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The 7024L15JG achieves ROHS3 compliance, whereas the 7024L30J is non-compliant. For applications subject to RoHS regulations, the 7024L15JG is the required selection.

Performance: The 7024L15JG provides superior access and write cycle times (15 ns versus 30 ns). This performance improvement is backward-compatible with designs specified for the 7024L30J, as faster memory does not introduce timing violations in systems designed for slower components.

Electrical and Mechanical Compatibility: Both parts share identical supply voltage ranges, operating temperature specifications, package geometry, and pinout configuration, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 7024L15JG replace the 7024L30J in existing designs?

A: Yes. The 7024L15JG is electrically and mechanically compatible with the 7024L30J. The faster access time (15 ns) does not create compatibility issues in systems designed for 30 ns operation.

Q: Are the pin configurations identical between these parts?

A: Yes. Both the 7024L30J and 7024L15JG use the 84-PLCC (J-Lead) package with identical pinout and mechanical dimensions (29.31 x 29.31 mm).

Q: What is the significance of the RoHS compliance difference?

A: The 7024L15JG is ROHS3 compliant, while the 7024L30J is non-compliant. For applications subject to RoHS directives, the 7024L15JG must be selected.

Q: Do both parts operate at the same supply voltage?

A: Yes. Both parts operate within the 4.5V to 5.5V supply voltage range and share identical operating temperature specifications (0°C to 70°C).

Q: What is the MSL rating, and does it differ between parts?

A: Both parts carry an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity and storage requirements.

Q: Is the 7024L15JG available in the same packaging format?

A: Yes. The 7024L15JG is supplied in 84-PLCC surface mount packaging, identical to the 7024L30J. The substitute is available in tube packaging format.
