SY89296UTI Equivalent & Substitute Parts

Part Overview

The SY89296UTI is a programmable delay line IC from Microchip Technology's Precision Edge® series, designed for precision timing applications. This 32-TQFP surface mount device provides 1024 programmable taps with a delay range of 3.2ns to 14.8ns and 10ps tap increment resolution. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SY89296UTI is determined by the following critical parameters:

Functional Equivalence Criteria:

• Number of Taps/Steps: 1024
• Function: Programmable
• Tap Increment: 10 ps
• Number of Independent Delays: 1
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

Electrical Compatibility Criteria:

• Supply Voltage Range: Must support the original 2.375V ~ 3.6V range or be compatible within design margins
• Delay Range: Must provide equivalent or superior delay coverage for the application

Package Compatibility:

• The original SY89296UTI uses 32-TQFP packaging. Substitutes may use 32-LQFP (functionally compatible but different physical footprint requiring PCB redesign)

Compliance Considerations:

• RoHS Status: Original part is non-compliant; active substitutes are RoHS3 compliant
• MSL Rating: Original part has MSL 3; active substitutes have MSL 2

Engineering Selection Recommendations

SY89296UTG (Direct Equivalent - Recommended for Pin-Compatible Replacement)

The SY89296UTG is the direct equivalent from Microchip Technology. It maintains identical electrical specifications and 32-TQFP packaging, enabling drop-in replacement without PCB modification. The part is active in production with RoHS3 compliance and improved MSL rating (2 vs. 3), providing better long-term reliability and regulatory alignment.

MC100EP196FAG and MC100EP196FAR2G (Cross-Manufacturer Substitutes - Requires PCB Redesign)

The onsemi MC100EP196 series provides functional equivalence with 1024 programmable taps and 10ps resolution. These parts use 32-LQFP packaging instead of 32-TQFP, requiring PCB footprint redesign. The delay range (2.36ns ~ 12.258ns) is narrower than the original, with a lower minimum delay. The supply voltage range is restricted to 3V ~ 3.6V, eliminating the 2.375V lower specification of the original. Both parts are active and RoHS3 compliant. MC100EP196FAR2G is supplied in Tape & Reel format for high-volume production; MC100EP196FAG is supplied in Tray format.

Frequently Asked Questions (FAQ)

Q: Can SY89296UTG be used as a direct replacement for SY89296UTI?

A: Yes. The SY89296UTG is electrically and mechanically identical to the SY89296UTI, with the same 32-TQFP package, delay specifications, and tap configuration. It can be used as a drop-in replacement without design changes.

Q: What is the primary difference between SY89296UTG and the original SY89296UTI?

A: The SY89296UTG is an active production part with RoHS3 compliance and MSL 2 rating, compared to the obsolete, non-compliant SY89296UTI with MSL 3 rating. Electrical performance is identical.

Q: Can MC100EP196FAG or MC100EP196FAR2G replace SY89296UTI without PCB modification?

A: No. These onsemi parts use 32-LQFP packaging instead of 32-TQFP, requiring PCB footprint redesign. Additionally, the supply voltage range is narrower (3V ~ 3.6V vs. 2.375V ~ 3.6V), and the delay range is reduced (2.36ns ~ 12.258ns vs. 3.2ns ~ 14.8ns).

Q: What are the key electrical differences between the Microchip SY89296 and onsemi MC100EP196 series?

A: Both provide 1024 programmable taps with 10ps increment resolution. The primary differences are: (1) Microchip supports 2.375V minimum supply; onsemi requires 3V minimum; (2) Microchip delay range is 3.2ns ~ 14.8ns; onsemi is 2.36ns ~ 12.258ns; (3) Package format differs (TQFP vs. LQFP).

Q: Which substitute should be selected for new designs?

A: For designs requiring pin-compatible replacement, use SY89296UTG. For new designs where PCB redesign is acceptable, either MC100EP196FAG (Tray) or MC100EP196FAR2G (Tape & Reel) can be selected based on production volume and packaging requirements. Verify that the narrower delay range and higher minimum supply voltage are compatible with application requirements.

Q: What is the difference between MC100EP196FAG and MC100EP196FAR2G?

A: Both parts are electrically identical. The difference is packaging format: MC100EP196FAG is supplied in Tray format for lower-volume applications; MC100EP196FAR2G is supplied in Tape & Reel format for high-volume automated assembly.

Q: Are all substitute parts RoHS3 compliant?

A: The SY89296UTG and both onsemi MC100EP196 variants are RoHS3 compliant. The original SY89296UTI is RoHS non-compliant.
