Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Electrical Compatibility Requirements:

• Maximum frequency: 133MHz or higher
• Input-to-output ratio: 1:9
• Supply voltage range: 3V ~ 3.6V
• Operating temperature range: 0°C ~ 70°C
• PLL with bypass capability
• Signal type compatibility (LVTTL or Clock input/output)

Mechanical Compatibility Requirements:

• Package type: 16-SOIC (0.154", 3.90mm Width)
• Surface mount mounting type
• Pin count: 16 pins

Compliance Requirements:

• ROHS3 compliant
• REACH unaffected status
• Active product status

Substitute parts are grouped into two categories: MFR Recommended substitutes (cross-manufacturer alternatives meeting all electrical and mechanical parameters) and Parametric Equivalents (same manufacturer variants with identical electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

MFR Recommended Substitutes (Microchip Technology):

PL123-09SC and PL123-09SC-R are manufacturer-recommended cross-platform alternatives. Both parts meet all electrical parameters with maximum frequency of 134MHz, exceeding the 133MHz specification of the main part. The primary distinction is packaging format: PL123-09SC is supplied in tube packaging, while PL123-09SC-R is supplied in tape and reel format. Both achieve ROHS3 compliance and maintain active product status. The Microchip variants feature improved moisture sensitivity (MSL 1 vs. MSL 3), providing extended shelf life and reduced handling constraints.

Parametric Equivalents (Renesas Electronics):

2309-1HDCG and 2309A-1DCG are parametric equivalents manufactured by Renesas. Both parts maintain identical electrical specifications to the main 2309-1DCG part, including 133MHz maximum frequency, 1:9 ratio, and LVTTL signal compatibility. These variants are suitable for applications requiring same-manufacturer sourcing or where existing supply chain relationships with Renesas are established. Inventory availability differs across variants, with 2309-1HDCG offering 2332 units and 2309A-1DCG offering 1109 units in stock.

Selection Criteria:

• For maximum frequency margin and improved moisture handling: select PL123-09SC or PL123-09SC-R
• For same-manufacturer continuity: select 2309-1HDCG or 2309A-1DCG
• For tape and reel packaging (high-volume assembly): select PL123-09SC-R
• For tube packaging (lower-volume or manual assembly): select PL123-09SC, 2309-1HDCG, or 2309A-1DCG

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can PL123-09SC replace 2309-1DCG in my application?

A: Yes. PL123-09SC meets all critical electrical parameters: 1:9 input-to-output ratio, 134MHz maximum frequency (exceeding the 133MHz requirement), 3V-3.6V supply voltage, 0°C-70°C operating temperature range, and PLL with bypass capability. Both parts use identical 16-SOIC packaging. The primary difference is manufacturer (Microchip vs. Renesas) and improved moisture sensitivity rating.

Q: What is the difference between PL123-09SC and PL123-09SC-R?

A: Both parts are electrically and mechanically identical. The difference is packaging format: PL123-09SC is supplied in tube packaging, while PL123-09SC-R is supplied in tape and reel format. Tape and reel packaging is standard for high-volume automated assembly, while tube packaging is typical for lower-volume or manual assembly operations.

Q: Are 2309-1HDCG and 2309A-1DCG true equivalents to 2309-1DCG?

A: Yes. Both are parametric equivalents manufactured by Renesas with identical electrical specifications to the main part. All three variants feature 133MHz maximum frequency, 1:9 ratio, LVTTL input/output, and 16-SOIC packaging. These variants differ only in internal design or manufacturing process while maintaining full functional compatibility.

Q: Does the Microchip PL123-09SC have better moisture sensitivity than the Renesas parts?

A: Yes. PL123-09SC and PL123-09SC-R have MSL 1 (unlimited shelf life), while 2309-1DCG, 2309-1HDCG, and 2309A-1DCG have MSL 3 (168-hour limit). MSL 1 provides extended storage capability and reduced handling constraints, particularly beneficial for long-term inventory management or applications with extended lead times.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. All substitute parts use identical 16-SOIC (0.154", 3.90mm Width) surface mount packaging with the same pin configuration and electrical interface. No PCB layout modifications are required for substitution.

Q: Are all these parts ROHS3 compliant?

A: Yes. All listed parts—2309-1DCG, PL123-09SC, PL123-09SC-R, 2309-1HDCG, and 2309A-1DCG—are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should I choose for a new design?

A: For new designs, PL123-09SC-R (tape and reel format) is recommended if high-volume automated assembly is planned, as it provides superior moisture sensitivity and standard packaging for production environments. For lower-volume applications or manual assembly, PL123-09SC (tube format) offers the same electrical performance with standard packaging. If manufacturer continuity is required, select 2309-1HDCG or 2309A-1DCG from Renesas.
