Key Parameters

Substitute Part Grouping Explanation

The ZL30409DDF1 is an obsolete Stratum clock synchronizer. Active substitute parts have been identified based on the following substitution criteria:

Allowed Substitution Parameters:

• Manufacturer: Microchip Technology (same manufacturer)
• Category: Clock/Timing (same functional category)
• PLL capability: Yes (required for clock synthesis)
• Operating Temperature: -40°C ~ 85°C (matching range)
• RoHS Status: ROHS3 Compliant (regulatory compliance maintained)
• MSL Rating: 1 (Unlimited) (moisture sensitivity compatibility)

Substitute Parts:

• ZL30162GDG2 (4-channel clock translator, 750MHz, 144-LBGA)
• ZL30163GDG2 (2-channel clock translator, 750MHz, 144-LBGA)

Both substitutes are active products from Microchip Technology with PLL functionality and matching environmental specifications. These parts operate at significantly higher frequencies and feature different package configurations and channel counts compared to the original ZL30409DDF1.

Parameter Comparison

Engineering Selection Recommendations

The ZL30409DDF1 is classified as obsolete and no longer available for new production orders. Selection of an active substitute is required for design continuation and manufacturing support.

ZL30162GDG2 and ZL30163GDG2 are both active products with full manufacturing support from Microchip Technology. Both substitutes maintain compliance with ROHS3 and REACH requirements, matching the regulatory status of the original component. Both devices feature PLL functionality and identical operating temperature ranges (-40°C to 85°C), ensuring thermal compatibility in existing applications.

The primary differences between the original and substitutes are frequency capability (19.44MHz versus 750MHz), package configuration (48-BSSOP versus 144-BGA), and application focus (Stratum versus Ethernet/Fibre Channel/SONET/SDH). Selection between ZL30162GDG2 and ZL30163GDG2 depends on channel count requirements: ZL30162GDG2 provides 4 channels while ZL30163GDG2 provides 2 channels.

Frequently Asked Questions (FAQ)

Q: Why is the ZL30409DDF1 no longer available? A: The ZL30409DDF1 is classified as obsolete by Microchip Technology and has been discontinued. Active substitute parts are required for new designs and ongoing production.

Q: What are the key differences between the ZL30409DDF1 and the substitute parts? A: The primary differences are frequency rating (19.44MHz versus 750MHz), package type (48-BSSOP versus 144-BGA), and application category (Stratum versus Ethernet/Fibre Channel/SONET/SDH). All three parts share PLL capability, identical operating temperature ranges, and equivalent regulatory compliance.

Q: Can ZL30162GDG2 and ZL30163GDG2 be used interchangeably? A: Both parts are functionally similar but differ in channel count. ZL30162GDG2 provides 4 channels while ZL30163GDG2 provides 2 channels. Selection depends on the specific channel requirements of your application.

Q: Are the substitute parts compatible with existing PCB layouts designed for the ZL30409DDF1? A: No. The substitute parts use different package configurations (144-BGA versus 48-BSSOP), requiring PCB redesign and layout modifications. Pin assignments and footprints are not compatible.

Q: Do the substitute parts maintain the same regulatory compliance as the original? A: Yes. Both ZL30162GDG2 and ZL30163GDG2 are ROHS3 compliant and REACH unaffected, matching the compliance status of the ZL30409DDF1.

Q: What is the moisture sensitivity level of the substitute parts? A: Both substitute parts have an MSL rating of 1 (Unlimited), identical to the original ZL30409DDF1, indicating no moisture sensitivity restrictions.
