Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI6C2409-1HWIEX is determined by strict equivalence across the following critical parameters:

• Device type classification as Zero Delay Buffer
• Maximum operating frequency of 133MHz
• Input-to-output ratio of 1:9
• Integrated PLL with bypass functionality
• Supply voltage range of 3V ~ 3.6V
• Operating temperature range of -40°C ~ 85°C
• 16-SOIC surface mount package footprint
• RoHS3 compliance

The substitute part 2309-1HDCGI8 (Renesas Electronics Corporation) meets all these core electrical and mechanical requirements. While input/output logic levels differ (LVTTL vs. TTL), both operate within compatible voltage specifications for this application category.

Parameter Comparison

Engineering Selection Recommendations

The 2309-1HDCGI8 from Renesas Electronics Corporation is the primary substitute for the obsolete PI6C2409-1HWIEX. Selection is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical specifications across frequency, voltage, and timing parameters
• Matching 16-SOIC package footprint enabling direct PCB compatibility
• ROHS3 compliance maintaining regulatory alignment
• Equivalent functional performance in Zero Delay Buffer applications

The difference in logic level specification (LVTTL vs. TTL) does not preclude substitution, as both operate within the specified 3V ~ 3.6V supply range and maintain compatible signal thresholds for this application category.

Frequently Asked Questions (FAQ)

Q: Can the 2309-1HDCGI8 be used as a direct replacement for the PI6C2409-1HWIEX?

A: Yes. Both devices share identical package footprints (16-SOIC), electrical specifications (133MHz, 1:9 ratio, 3V ~ 3.6V supply), and functional classification as Zero Delay Buffers with integrated PLL and bypass capability.

Q: What is the significance of the logic level difference (TTL vs. LVTTL)?

A: Both TTL and LVTTL operate within the specified 3V ~ 3.6V supply voltage range. The voltage thresholds remain compatible for this application, and the difference does not prevent functional substitution.

Q: Why is the PI6C2409-1HWIEX classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Diodes Incorporated. The 2309-1HDCGI8 maintains active production status, ensuring availability for new designs and production continuity.

Q: Are there any handling differences between these parts?

A: The PI6C2409-1HWIEX has MSL 1 (unlimited moisture sensitivity), while the 2309-1HDCGI8 has MSL 3 (168 hours). Standard moisture control procedures for MSL 3 components are required during storage and assembly of the substitute part.

Q: Is the 16-SOIC package footprint identical between both parts?

A: Yes. Both devices use 16-SOIC (0.154", 3.90mm Width) surface mount packaging, enabling direct PCB layout compatibility without redesign.
