Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZL30122GGG is determined by strict alignment across the following critical parameters:

• Manufacturer and base product number (ZL30122 series)
• Frequency specification (622.08MHz maximum)
• Input/output signal types (LVCMOS input, LVCMOS/LVPECL output)
• Differential signal configuration (No/Yes)
• Supply voltage range (2.97V ~ 3.63V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (64-CABGA 9x9 BGA)
• PLL functionality (required)

The ZL30122GGG2 meets all these criteria as a direct substitute within the ZL30122 product family, with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ZL30122GGG2 is the direct substitute for the ZL30122GGG. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility.

The ZL30122GGG2 offers two significant advantages:

• Active product status ensures continued availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the ZL30122GGG is RoHS non-compliant

The moisture sensitivity level difference (MSL 1 versus MSL 3) reflects standard manufacturing variations and does not affect functional substitution. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ZL30122GGG2 replace ZL30122GGG in existing designs?

A: Yes. The ZL30122GGG2 is a direct substitute with identical electrical and mechanical specifications. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The ZL30122GGG is obsolete, meaning Microchip Technology no longer manufactures it. The ZL30122GGG2 is active and remains in production, ensuring long-term availability and supply chain stability.

Q: Does the RoHS compliance difference affect substitution?

A: No. RoHS compliance is a manufacturing and environmental standard. Both parts function identically in circuit operation. However, the ZL30122GGG2's ROHS3 compliance aligns with current regulatory requirements for new designs and procurement.

Q: Are the packages identical?

A: Yes. Both parts use the 64-CABGA (9x9) BGA package with identical pinout and mechanical dimensions.

Q: What does the MSL rating difference mean?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 allows unlimited storage; MSL 3 allows 168 hours. This difference reflects standard manufacturing practices and does not affect functional performance or substitution eligibility.

Q: Are there any other ZL30122 variants available?

A: Based on provided data, ZL30122GGG2 is the documented substitute. Both parts belong to the ZL30122 base product family manufactured by Microchip Technology.
