Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2309-1DCGI8 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Equivalence Criteria:

• Frequency maximum rating of 133MHz or higher
• Input-to-output ratio of 1:9
• Supply voltage range of 3V to 3.6V
• PLL with bypass capability
• LVTTL or Clock-level input/output compatibility
• Single circuit configuration

Mechanical Equivalence Criteria:

• 16-SOIC (0.154", 3.90mm Width) package footprint
• Surface mount mounting type
• Packaging format compatibility (Tape & Reel or Tube)

Compliance Criteria:

• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification

The identified substitute parts meet all electrical and mechanical requirements while maintaining regulatory compliance. Packaging format differences (Tape & Reel versus Tube) do not affect functional substitution but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

Both PL123-09SC and PL123-09SC-R from Microchip Technology are functionally equivalent to the 2309-1DCGI8 for clock distribution and timing applications requiring 1:9 multiplication at frequencies up to 133MHz within the 3V to 3.6V supply range.

PL123-09SC-R is the preferred substitute when Tape & Reel packaging is required for automated assembly processes, offering significantly higher inventory availability (6849 units) and identical mechanical compatibility with the main part.

PL123-09SC is suitable for applications where Tube packaging is acceptable, providing equivalent electrical performance with lower inventory levels (661 units).

Both substitute parts maintain ROHS3 compliance and REACH unaffected status. The operating temperature range of the Microchip parts (0°C to 70°C) is narrower than the main part (-40°C to 85°C), requiring verification that application temperature requirements fall within this range. The Microchip parts feature superior moisture sensitivity ratings (MSL 1 Unlimited versus MSL 3 168 Hours), providing enhanced reliability in humid storage and handling environments.

Frequently Asked Questions (FAQ)

Q: Can PL123-09SC and PL123-09SC-R be used interchangeably with the 2309-1DCGI8?

A: Yes, both Microchip parts are electrically and mechanically equivalent. The primary difference is packaging format: PL123-09SC-R uses Tape & Reel while PL123-09SC uses Tube. Both fit the same 16-SOIC footprint and deliver identical electrical performance.

Q: What is the significance of the frequency difference (133MHz versus 134MHz)?

A: The Microchip parts are rated to 134MHz, which exceeds the 2309-1DCGI8 specification of 133MHz. This higher rating provides additional design margin and does not create compatibility issues when substituting into applications designed for 133MHz operation.

Q: Why do the operating temperature ranges differ?

A: The 2309-1DCGI8 operates from -40°C to 85°C, while the Microchip substitutes operate from 0°C to 70°C. Substitution is valid only when the application's actual operating temperature requirements fall within the 0°C to 70°C range. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must use the original Renesas part.

Q: What does Moisture Sensitivity Level (MSL) mean for component handling?

A: MSL indicates how long a component can be stored in dry conditions before moisture absorption becomes problematic. The 2309-1DCGI8 has MSL 3 (168 hours), requiring baking before reflow if exposed to humidity beyond this period. The Microchip substitutes have MSL 1 (Unlimited), meaning they can be stored indefinitely without moisture concerns, providing superior handling flexibility.

Q: Are there any signal compatibility considerations between LVTTL and Clock designations?

A: Both signal types operate within compatible voltage levels for the 3V to 3.6V supply range. The Clock designation on the Microchip parts indicates the same LVTTL-compatible signal levels as the Renesas part. No signal conditioning is required when substituting.

Q: Which substitute part should be selected for new designs?

A: PL123-09SC-R is recommended for new designs due to superior inventory availability (6849 units), Tape & Reel packaging compatibility with automated assembly, and improved moisture sensitivity characteristics. This part provides the best combination of supply chain reliability and manufacturing process compatibility.
