PL123-09NOC Clock Fanout Buffer Equivalent & Substitute Parts

Part Overview

The PL123-09NOC is a Clock Fanout Buffer (Distribution) IC manufactured by Microchip Technology, designed for 1:9 clock distribution at frequencies up to 134 MHz. This component is classified as Obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure long-term supply chain reliability. The part is packaged in 16-TSSOP (0.173", 4.40mm Width) surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL123-09NOC is determined by the following critical parameters that must remain constant:

• Functional Equivalence: Type (Fanout Buffer), Number of Circuits (1), and Ratio (1:9)
• Electrical Performance: Frequency - Max (134 MHz), Voltage - Supply (1.62V ~ 3.63V), Operating Temperature (0°C ~ 70°C)
• Manufacturer Consistency: Microchip Technology
• Base Product Number: PL123
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

The PL123-09NSC qualifies as a direct substitute based on identical electrical specifications and functional parameters. The primary difference is the package configuration, which transitions from 16-TSSOP to 16-SOIC, both surface mount options with compatible pinout arrangements for this device class.

Parameter Comparison

Engineering Selection Recommendations

The PL123-09NSC is the manufacturer-recommended substitute for the obsolete PL123-09NOC. Both parts maintain identical electrical specifications, functional characteristics, and compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1). The transition from 16-TSSOP to 16-SOIC packaging represents a standard industry practice for maintaining active product lines while preserving functional equivalence.

The PL123-09NSC carries Active product status, ensuring continued availability and supply chain support. Selection of the substitute part is appropriate for new designs and replacement applications where the 16-SOIC package footprint is compatible with the target PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the PL123-09NSC directly replace the PL123-09NOC in existing designs?

A: Electrical and functional compatibility is complete. PCB layout modification is required due to package geometry differences between 16-TSSOP (0.173" width) and 16-SOIC (0.154" width). Pinout arrangement remains consistent for this device class.

Q: What is the primary reason for substitution?

A: The PL123-09NOC is classified as Obsolete. The PL123-09NSC is the active equivalent from the same manufacturer, ensuring continued supply availability and support.

Q: Are compliance certifications maintained in the substitute part?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What are the key parameters that must match for substitution?

A: Functional type (Fanout Buffer), circuit count (1), input:output ratio (1:9), maximum frequency (134 MHz), supply voltage range (1.62V ~ 3.63V), and operating temperature range (0°C ~ 70°C) must remain constant.

Q: Are there inventory considerations between the two parts?

A: The PL123-09NOC has 824 pieces in stock (Obsolete status). The PL123-09NSC has 773 pieces in stock (Active status). Active product status ensures ongoing availability for the substitute part.
