Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SY89112UMG is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Fanout Buffer (Distribution), Multiplexer with 2:12 input-to-output ratio
• Signal Compatibility: Differential input acceptance (CML, LVDS, LVPECL) and LVPECL output generation
• Frequency Performance: Maximum operating frequency of 3 GHz
• Electrical Specifications: Supply voltage range 2.375V ~ 3.6V and operating temperature range -40°C ~ 85°C
• Physical Form Factor: 44-VFQFN Exposed Pad package (44-MLF®, 7x7 footprint)
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status

The SY89112UMY meets all substitution criteria as a direct equivalent from the same manufacturer, Microchip Technology, with identical functional and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SY89112UMY is the direct substitute for the obsolete SY89112UMG. Both parts share identical electrical, functional, and mechanical specifications. The primary distinction is product lifecycle status: the SY89112UMG is obsolete, while the SY89112UMY maintains active production status.

For new designs and production applications, the SY89112UMY is the appropriate selection. Both parts maintain ROHS3 compliance and REACH Unaffected regulatory status, ensuring compatibility with current environmental and safety standards. The packaging difference (UMG supplied in standard packaging versus UMY supplied in Tray) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SY89112UMY be used as a direct replacement for the SY89112UMG in existing designs?

A: Yes. The SY89112UMY is electrically and mechanically equivalent to the SY89112UMG. Both parts feature identical input-to-output ratios (2:12), signal types (CML/LVDS/LVPECL input, LVPECL output), frequency performance (3 GHz maximum), supply voltage range (2.375V ~ 3.6V), and package form factor (44-VFQFN Exposed Pad, 44-MLF®, 7x7).

Q: What is the difference between the SY89112UMG and SY89112UMY?

A: The primary difference is product status. The SY89112UMG is obsolete, while the SY89112UMY is active. The SY89112UMY is supplied in Tray packaging, whereas the SY89112UMG was supplied in standard packaging. All electrical and functional specifications are identical.

Q: Are there any PCB layout or thermal considerations when substituting the SY89112UMY for the SY89112UMG?

A: No layout or thermal modifications are required. Both parts use the identical 44-VFQFN Exposed Pad package (44-MLF®, 7x7 footprint), ensuring pin-for-pin compatibility and identical thermal characteristics.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SY89112UMG and SY89112UMY are ROHS3 Compliant and REACH Unaffected, meeting current environmental and safety requirements.

Q: Why is the SY89112UMG classified as obsolete?

A: The SY89112UMG has reached end-of-life status. The SY89112UMY represents the active production equivalent and is the recommended part for all new applications and procurement.
