Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL23EP09NZSC-1HT is determined by the following critical parameters:

• Package Compatibility: All substitute parts must use 16-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout and assembly compatibility.
• Functional Topology: All substitutes maintain 1:9 fanout buffer architecture with identical input-to-output ratio.
• Signal Compatibility: Input and output signal types must be compatible with the application circuit requirements.
• Voltage Supply Range: Operating voltage must overlap or be contained within the application's supply specification.
• Operating Temperature Range: Temperature rating must meet or exceed the application's thermal requirements.

The identified substitute parts are Renesas Electronics Corporation 2309N series devices, which share identical package geometry and fanout ratio. However, these substitutes operate at reduced maximum frequency (133.33 MHz versus 220 MHz) and feature different signal level specifications (LVTTL input/output versus LVCMOS output on the original part).

Parameter Comparison

Engineering Selection Recommendations

Selection among the Renesas 2309N series substitutes must account for the following factors:

Frequency Derating: The substitute parts operate at 133.33 MHz maximum, representing a 39% reduction from the original 220 MHz specification. Substitution is valid only when the application clock frequency does not exceed 133.33 MHz.

Signal Level Translation: The original part provides LVCMOS output while substitutes provide LVTTL output. Compatibility depends on the receiving circuit's input threshold specifications. LVTTL output is generally compatible with LVCMOS input stages, but the inverse relationship requires verification.

Temperature Range: The 2309NZ-1HDCGI and 2309NZ-1HDCGI8 variants extend the operating temperature range to -40°C ~ 85°C, providing broader thermal coverage than both the original part (0°C ~ 70°C) and the 2309NZ-1HDCG/2309NZ-1HDCG8 variants (0°C ~ 70°C).

Packaging Format: The Tape & Reel (TR) format variants (2309NZ-1HDCG8 and 2309NZ-1HDCGI8) are preferred for high-volume production. Tube format variants (2309NZ-1HDCG and 2309NZ-1HDCGI) are suitable for lower-volume or manual assembly operations.

Compliance Status: All Renesas substitutes are ROHS3 compliant and REACH unaffected, supporting modern supply chain and environmental requirements. The original Skyworks part status is not specified for these certifications.

Product Lifecycle: All Renesas substitutes maintain Active product status, ensuring long-term availability and supply continuity compared to the Not For New Designs status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 2309N series parts directly replace the SL23EP09NZSC-1HT without circuit modifications?

A: Direct replacement is possible only if the application clock frequency does not exceed 133.33 MHz and the receiving circuit accepts LVTTL signal levels. The identical 16-SOIC package and 1:9 fanout ratio ensure mechanical and functional compatibility at the pin level. Signal level compatibility must be verified against the specific receiving circuit specifications.

Q: What is the primary limitation when substituting with the Renesas 2309N series?

A: The maximum frequency specification is reduced from 220 MHz to 133.33 MHz. Applications operating at clock frequencies above 133.33 MHz cannot use these substitutes. Additionally, the output signal type changes from LVCMOS to LVTTL, which may require verification in circuits with strict signal level requirements.

Q: Are there differences between the 2309NZ-1HDCG and 2309NZ-1HDCGI variants?

A: The primary difference is the operating temperature range. The 2309NZ-1HDCG operates from 0°C to 70°C, matching the original part's thermal specification. The 2309NZ-1HDCGI extends the range to -40°C to 85°C, providing broader thermal coverage. Both variants are functionally identical in frequency, voltage, and signal specifications.

Q: What is the significance of the "8" suffix in part numbers 2309NZ-1HDCG8 and 2309NZ-1HDCGI8?

A: The "8" suffix indicates Tape & Reel (TR) packaging format, optimized for automated assembly and high-volume production. Parts without the "8" suffix use Tube packaging, suitable for lower-volume or manual assembly operations. Electrical and functional specifications are identical between the two packaging formats.

Q: How does the Moisture Sensitivity Level (MSL) affect substitution decisions?

A: The original part has MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The Renesas substitutes have MSL 3 (168 Hours), requiring controlled storage and handling within 168 hours of package opening. This affects supply chain logistics and storage procedures but does not impact electrical performance if proper moisture control is maintained.

Q: Is the voltage supply range compatible between the original and substitute parts?

A: The original part specifies 2.97V ~ 3.63V while substitutes specify 3V ~ 3.6V. The substitute range is slightly narrower but overlaps substantially. Substitution is valid for applications operating within the 3V ~ 3.6V window. Applications requiring operation below 3V or above 3.6V cannot use the Renesas substitutes.
