Substitute Part Grouping Explanation

Substitution for the 7024S20G is determined by strict equivalence in the following critical parameters:

  • Memory capacity: 64Kbit
  • Memory organization: 4K x 16
  • Interface type: Parallel, dual-port asynchronous
  • Package: 84-BPGA (27.94x27.94)
  • Voltage supply range: 4.5V ~ 5.5V
  • Operating temperature range: 0°C ~ 70°C
  • Mounting type: Through Hole

Substitute parts must maintain identical memory capacity, organization, interface architecture, and physical packaging. Access time and write cycle time may be equal or faster (lower values) without functional impact. All substitute parts listed are manufactured by Renesas Electronics Corporation and share the same base electrical and mechanical specifications as the main part.

Engineering Selection Recommendations

The 7024S20G is obsolete; active production alternatives are available. Both substitute parts maintain full electrical and mechanical compatibility with the original specification.

The 7024L20G is functionally identical to the 7024S20G, offering equivalent 20 ns access and write cycle times with active product status. This part is the direct replacement for applications requiring no timing relaxation.

The 7024S35G provides the same memory capacity and organization with extended access and write cycle times of 35 ns. This substitute is suitable for applications where the slower timing specification does not impact system performance. The 35 ns timing specification represents a relaxation of the original 20 ns requirement and is compatible with designs tolerant of increased memory latency.

Both substitute parts carry identical RoHS non-compliance status and MSL ratings as the original part. Compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.32.0041) are consistent across all three parts.

Frequently Asked Questions (FAQ)

Q: Can the 7024L20G directly replace the 7024S20G?

A: Yes. The 7024L20G maintains identical memory capacity (64Kbit), organization (4K x 16), access time (20 ns), write cycle time (20 ns), voltage supply range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 84-BPGA package specifications. The only difference is product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified).

Q: Can the 7024S35G replace the 7024S20G?

A: The 7024S35G is electrically compatible with the 7024S20G for all parameters except access and write cycle times, which are extended to 35 ns. This substitute is suitable only for applications where the system timing budget accommodates the slower memory response. If the original design requires 20 ns timing, the 7024S35G is not appropriate.

Q: Are there packaging differences between these parts?

A: All three parts use the same 84-BPGA (27.94x27.94) package with through-hole mounting. The 7024L20G and 7024S35G are supplied in Tray packaging, while the main part packaging format is not specified. This does not affect functional compatibility.

Q: What is the significance of the obsolete status?

A: The 7024S20G is classified as obsolete, indicating Renesas Electronics has discontinued production. The 7024L20G and 7024S35G are active products with ongoing manufacturing support, making them suitable for new designs and long-term system support.

Q: Are there compliance or regulatory differences?

A: All three parts share identical compliance status: RoHS non-compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8542.32.0041. MSL rating is 1 (Unlimited) for all parts.
