SY89328LMI-TR Equivalent & Substitute Parts

Part Overview

The SY89328LMI-TR is a mixed signal translator IC from Microchip Technology's SY89 series, designed for unidirectional signal translation between LVPECL and LVTTL logic levels. This component features 1 circuit with 2 channels per circuit in an 8-MLF® (2x2) surface mount package. The SY89328LMI-TR is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY89328LMI-TR is determined by strict equivalence across the following critical parameters:

• Translator type: Mixed Signal
• Channel configuration: Unidirectional, 1 circuit, 2 channels per circuit
• Signal compatibility: LVPECL and LVTTL input/output support
• Output capability: Differential and single-ended
• Package: 8-MLF® (2x2) form factor
• Mounting: Surface mount
• Operating temperature range: -40°C ~ 85°C
• Moisture sensitivity: MSL 1

The SY89328LMG-TR meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and product status (discontinued vs. active).

Parameter Comparison

Engineering Selection Recommendations

The SY89328LMG-TR is the direct functional equivalent to the SY89328LMI-TR. Both parts share identical electrical specifications, signal translation capabilities, and physical package dimensions. Selection between these parts should be based on the following factors:

Product Availability: The SY89328LMI-TR is discontinued at DiGi Electronics. The SY89328LMG-TR maintains active product status with current inventory availability.

Compliance Status: The SY89328LMG-TR is ROHS3 compliant, whereas the SY89328LMI-TR is RoHS non-compliant. For applications subject to RoHS regulations, the SY89328LMG-TR is the required selection.

Packaging Format: The SY89328LMI-TR is supplied in Tape & Reel format, while the SY89328LMG-TR is available in Cut Tape and Digi-Reel® formats. Packaging selection depends on production volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Are the SY89328LMI-TR and SY89328LMG-TR electrically identical?

A: Yes. Both parts are mixed signal translators with identical channel configuration (1 circuit, 2 channels), signal support (LVPECL/LVTTL), output types (differential and single-ended), operating temperature range (-40°C ~ 85°C), and package specifications (8-MLF® 2x2).

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®), product status (discontinued vs. active), and RoHS compliance (non-compliant vs. ROHS3 compliant). The electrical and functional specifications are identical.

Q: Can I use the SY89328LMG-TR as a direct replacement in my design?

A: Yes. The SY89328LMG-TR is a direct functional equivalent. No design changes are required. The 8-MLF® package footprint is identical, and all electrical parameters match.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance affects regulatory requirements and supply chain considerations, not electrical compatibility. If your application or market requires RoHS compliance, the SY89328LMG-TR is the appropriate selection.

Q: Which packaging format should I choose?

A: Tape & Reel (TR) format is typically used for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® formats are suitable for lower volumes or mixed component orders. Selection depends on your production requirements and assembly equipment.
