SY89295UTI-TR Equivalent & Substitute Parts

Part Overview

The SY89295UTI-TR is a programmable delay line IC manufactured by Microchip Technology, designed for precision timing applications requiring variable delay adjustment. This 32-TQFP surface mount device provides 1024 taps with 10 ps increments, delivering delays from 3.2ns to 14.8ns. The product is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY89295UTI-TR is determined by the following critical parameters:

• Number of Taps/Steps: Must equal 1024 to maintain programmable delay resolution
• Tap Increment: Must equal 10 ps for consistent step granularity
• Function: Must be Programmable to support equivalent control methodology
• Number of Independent Delays: Must equal 1 for single-channel operation
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Mounting Type: Must be Surface Mount
• Package Footprint: 32-pin LQFP or 32-TQFP packages with 7x7mm dimensions are mechanically compatible
• Voltage Supply Range: Must overlap with or encompass the original 2.375V ~ 3.6V specification

All identified substitute parts meet these core criteria. The onsemi MC100EP195 and MC10EP195 series devices provide equivalent functionality with active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain functional equivalence to the SY89295UTI-TR based on core delay line specifications. Selection among alternatives should prioritize the following factors:

Product Availability and Status: MC100EP195FAR2G offers the highest inventory (3500 pcs) with Tape & Reel packaging, matching the original SY89295UTI-TR packaging format. MC10EP195FAG provides 4055 pcs in stock. Both MC100EP195BFAG and MC100EP195FAG are available in Tray packaging with 1334 and 1505 pcs respectively.

Compliance and Environmental Requirements: All substitute parts are ROHS3 compliant and REACH unaffected, providing improved regulatory compliance compared to the RoHS non-compliant original. All substitutes feature MSL 2 (1 Year) moisture sensitivity, superior to the original MSL 3 (168 Hours).

Delay Range Considerations: The substitute parts provide lower initial delay values (2.2ns to 2.5ns versus 3.2ns) and reduced maximum delays (12.2ns to 13ns versus 14.8ns). Applications requiring delays within the 2.2ns to 12.2ns range are fully compatible with MC100EP195FAG, MC100EP195FAR2G, or MC10EP195FAG. Applications requiring delays above 12.2ns or below 2.5ns require evaluation of circuit-level timing adjustments.

Voltage Supply Range: Substitute parts operate at 3V ~ 3.6V, which overlaps the original 2.375V ~ 3.6V range. Designs operating below 3V require confirmation of compatibility with the substitute parts' minimum supply voltage specification.

Frequently Asked Questions (FAQ)

Q: Can MC100EP195FAR2G directly replace SY89295UTI-TR in existing PCB designs?

A: MC100EP195FAR2G is mechanically and functionally compatible. Both use 32-pin packages with 7x7mm footprints. The LQFP package of the substitute is pin-compatible with the TQFP package of the original. Verify that your circuit operates within the 3V ~ 3.6V supply range and that required delays fall within the 2.2ns ~ 12.2ns window.

Q: What is the difference between MC100EP195FAG and MC100EP195FAR2G?

A: Both parts are electrically identical with matching delay specifications (2.2ns ~ 12.2ns). The primary difference is packaging: MC100EP195FAG is supplied in Tray format, while MC100EP195FAR2G is supplied in Tape & Reel (TR) format. Select based on your assembly process requirements and inventory management preferences.

Q: Why do substitute parts have lower maximum delay values than the original?

A: The substitute parts provide maximum delays of 12.2ns to 13ns compared to the original 14.8ns. This reflects design optimization in the onsemi MC100EP and MC10EP series. Applications requiring delays above 12.2ns must implement alternative timing solutions or evaluate circuit redesign.

Q: Are the onsemi MC100EP195 and MC10EP195 series interchangeable?

A: Both series meet the core substitution criteria with identical delay specifications and tap configurations. The MC100EP series represents the higher-performance line, while the MC10EP series provides equivalent functionality. Selection between series depends on availability, cost, and specific application performance requirements.

Q: What packaging options are available for these substitute parts?

A: MC100EP195BFAG and MC100EP195FAG are available in Tray packaging. MC100EP195FAR2G is available in Tape & Reel (TR) format, matching the original SY89295UTI-TR packaging. MC10EP195FAG packaging format is not specified in available data.

Q: Do substitute parts require different PCB layout considerations?

A: All substitute parts use identical 32-pin LQFP packages with 7x7mm dimensions. PCB layouts designed for the original SY89295UTI-TR 32-TQFP package are compatible with substitute LQFP packages without modification, as both packages share the same footprint and pin spacing.
