Parameter Comparison

Engineering Selection Recommendations

Both PL123-09SC and PL123-09SC-R from Microchip Technology meet the electrical and mechanical specifications required for substitution with the 2309-1DCG8. The substitute parts exceed the maximum frequency specification at 134MHz compared to the main part's 133MHz, while maintaining identical supply voltage, operating temperature range, input-to-output ratio, and package dimensions.

All three parts maintain active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance across applications.

The primary distinction between substitute options is packaging format: PL123-09SC is supplied in Tube packaging, while PL123-09SC-R is supplied in Tape & Reel format. Selection between these substitutes should be based on procurement and assembly process requirements rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: What makes PL123-09SC and PL123-09SC-R suitable substitutes for 2309-1DCG8?

A: Both Microchip parts maintain identical electrical specifications including 1:9 input-to-output ratio, 3V to 3.6V supply voltage, 0°C to 70°C operating temperature range, and PLL with bypass functionality. The 16-SOIC package dimensions and surface mount configuration are mechanically identical. Maximum frequency specifications of 134MHz exceed the main part's 133MHz requirement.

Q: Are there differences between PL123-09SC and PL123-09SC-R?

A: The electrical and mechanical specifications are identical. The difference is packaging format: PL123-09SC uses Tube packaging while PL123-09SC-R uses Tape & Reel format. Selection depends on assembly process requirements and procurement preferences.

Q: Can these substitutes be used in existing PCB designs without modification?

A: Yes. The 16-SOIC package footprint and pin configuration are identical across all three parts, allowing direct substitution without PCB layout changes.

Q: What is the significance of the 1MHz frequency difference between the main part and substitutes?

A: The substitute parts' 134MHz maximum frequency specification exceeds the 2309-1DCG8's 133MHz rating. This provides additional performance margin and does not restrict compatibility in applications designed for the main part.

Q: Are compliance certifications equivalent across all three parts?

A: Yes. All three parts maintain RoHS3 compliance and REACH unaffected status, ensuring equivalent regulatory compliance for end applications.
