SY89295UTI Equivalent & Substitute Parts

Part Overview

The SY89295UTI is a programmable delay line IC from Microchip Technology's Precision Edge® series, designed for precision timing applications requiring variable delay control. This component features 1024 programmable taps with 10 ps increments, delivering delays from 3.2ns to 14.8ns in a 32-TQFP surface mount package. The part is currently obsolete, making equivalent substitutes necessary for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Functional Equivalence: 1024 programmable taps with 10 ps tap increment
• Delay Range Compatibility: Total available delays must encompass or closely align with the 3.2ns ~ 14.8ns range
• Electrical Specifications: Supply voltage range and operating temperature must support the application
• Package Compatibility: Surface mount packages (TQFP or LQFP variants) with equivalent pin counts and footprints
• Compliance Status: Active product status and RoHS3 compliance preferred for new designs

The substitute parts are grouped into two categories:

Category 1 - Direct Microchip Equivalent: SY89295UTG maintains identical electrical specifications and tap configuration with improved compliance status (Active, RoHS3 Compliant).

Category 2 - onsemi Cross-Manufacturer Equivalents: MC100EP195 series (BFAG, FAG, FAR2G variants) and MC10EP195FAG provide functional equivalence with slightly reduced delay range (2.2ns ~ 13ns) and different package designation (32-LQFP instead of 32-TQFP), but maintain the same tap count and increment specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): SY89295UTG is the optimal substitute, maintaining identical electrical specifications and tap configuration while offering Active product status and RoHS3 compliance. This part requires no circuit redesign and provides superior long-term availability and environmental compliance.

For Cross-Manufacturer Substitution: The onsemi MC100EP195 series (BFAG, FAG, FAR2G) and MC10EP195FAG provide functional equivalence with the following considerations:

• All onsemi alternatives are Active products with RoHS3 compliance
• Delay range is reduced compared to the original part (maximum 13ns vs. 14.8ns)
• Package designation changes from 32-TQFP to 32-LQFP; both are 7x7mm surface mount packages with equivalent pin counts
• Supply voltage minimum increases from 2.375V to 3V, requiring circuit verification for low-voltage applications
• Moisture sensitivity improves to MSL 2 (1 Year) across all onsemi variants

Packaging Variants: MC100EP195FAR2G is supplied in Tape & Reel format with highest inventory availability (3500 pcs), while MC100EP195FAG and MC100EP195BFAG are supplied in Tray packaging. MC10EP195FAG offers the highest inventory level (4055 pcs) among individual part selections.

Frequently Asked Questions (FAQ)

Q: Can SY89295UTG be used as a direct drop-in replacement for SY89295UTI?

A: Yes. SY89295UTG maintains identical electrical specifications, tap configuration (1024 taps, 10 ps increment), delay range (3.2ns ~ 14.8ns), supply voltage (2.375V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The primary differences are product status (Active vs. Obsolete), RoHS compliance (RoHS3 vs. non-compliant), and packaging format (Tray vs. unspecified). No circuit modifications are required.

Q: What are the key differences between the Microchip SY89295 series and onsemi MC100EP195 series?

A: Both maintain 1024 programmable taps with 10 ps increments and identical operating temperature ranges. The primary differences are: (1) delay range—SY89295 provides 3.2ns ~ 14.8ns while MC100EP195 provides 2.2ns ~ 12.2ns or 2.5ns ~ 13ns depending on variant; (2) supply voltage—SY89295 operates from 2.375V while MC100EP195 requires minimum 3V; (3) package designation—SY89295 uses 32-TQFP while MC100EP195 uses 32-LQFP, though both are 7x7mm surface mount packages with equivalent footprints.

Q: Are 32-TQFP and 32-LQFP packages mechanically compatible?

A: Both packages are 7x7mm surface mount packages with 32 pins and equivalent footprints. However, PCB layout verification is required to confirm compatibility with existing designs, as subtle differences in pin placement or lead geometry may exist between manufacturers.

Q: Which substitute part offers the best long-term availability?

A: MC10EP195FAG offers the highest current inventory (4055 pcs) and is an Active product from onsemi. MC100EP195FAR2G (Tape & Reel format) provides 3500 pcs inventory. Both are suitable for production quantities with assured long-term supply.

Q: What is the impact of the reduced delay range in onsemi substitutes?

A: onsemi MC100EP195 variants provide maximum delays of 12.2ns to 13ns compared to 14.8ns for the SY89295UTI. Applications requiring delays exceeding 12.2ns cannot use these substitutes. Verify your maximum delay requirement before selecting an onsemi alternative.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. SY89295UTG and all onsemi variants (MC100EP195BFAG, MC100EP195FAG, MC100EP195FAR2G, MC10EP195FAG) are RoHS3 compliant. The original SY89295UTI is RoHS non-compliant.
