Substitute Part Grouping Explanation

Substitution between the 7024S15J and 7024L15JG is valid based on the following criteria:

Electrical Compatibility:

• Identical memory capacity (64Kbit)
• Identical memory organization (4K x 16)
• Identical access time (15 ns)
• Identical write cycle time (15 ns)
• Identical supply voltage range (4.5V ~ 5.5V)
• Identical operating temperature range (0°C ~ 70°C)
• Identical memory interface (Parallel, dual-port asynchronous)

Mechanical Compatibility:

• Identical package type (84-PLCC with J-Lead)
• Identical physical dimensions (29.31x29.31 mm)
• Identical mounting type (Surface Mount)
• Identical MSL rating (3, 168 Hours)

Regulatory Alignment:

• Both parts share identical ECCN (EAR99) and HTSUS (8542.32.0041) classifications
• Both are REACH Unaffected

The 7024L15JG differs from the 7024S15J only in product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant), with no impact on functional or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 7024L15JG is the direct functional equivalent for the obsolete 7024S15J. Selection of the substitute part is based on:

Product Availability: The 7024S15J is classified as obsolete, making the 7024L15JG the active alternative from the same manufacturer with identical electrical and mechanical specifications.

Regulatory Compliance: The 7024L15JG meets ROHS3 compliance requirements, whereas the 7024S15J does not. For applications subject to RoHS directives or customer compliance mandates, the 7024L15JG is the appropriate selection.

Pin-for-Pin Compatibility: Both parts share identical 84-PLCC packaging, pinout, and electrical characteristics, enabling direct substitution without circuit redesign.

Supply Chain Continuity: With 925 units in stock, the 7024L15JG provides supply continuity for systems currently using the 7024S15J.

Frequently Asked Questions (FAQ)

Q: Can the 7024L15JG replace the 7024S15J in existing designs?

A: Yes. The 7024L15JG is pin-for-pin compatible with identical electrical specifications (64Kbit capacity, 15 ns access time, 4.5V–5.5V supply, 0°C–70°C operating range) and identical 84-PLCC packaging. No circuit modifications are required.
