Z8523320ASG Equivalent & Substitute Parts

Part Overview

The Z8523320ASG is a specialized interface integrated circuit manufactured by Zilog in the EMSCC™ series. This 44-LQFP surface mount device operates within a 4.5V to 5.5V supply voltage range and is classified as Active in product status. The device is ROHS3 compliant with MSL 3 rating (168 hours), making it suitable for industrial and commercial applications requiring reliable interface functionality.

Identifying equivalent and substitute parts becomes necessary when the primary component faces supply constraints, end-of-life considerations, or when design flexibility allows for alternative interface solutions that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z8523320ASG is determined by the following critical parameters:

• Category: All substitutes must be classified as Interface components
• Mounting Type: Surface mount technology is required for PCB compatibility
• RoHS Compliance: ROHS3 compliance is mandatory for regulatory alignment
• Voltage Supply Range: Operating voltage must be compatible with 4.5V to 5.5V systems or support overlapping ranges
• MSL Rating: Moisture sensitivity level must be acceptable for storage and handling conditions
• Product Status: Active or equivalent status ensures ongoing availability and support

The identified substitute parts (GS6042-INE3, AD6623ASZ, MAX7347AEE+, AD7569BRZ, AD9985ABSTZ-110) meet the core interface category and surface mount requirements. However, variations in package type, pin count, and voltage specifications create distinct substitution scenarios based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

AD7569BRZ presents the closest electrical compatibility with the Z8523320ASG, offering a voltage supply range of 4.75V to 5.25V that overlaps substantially with the primary part's 4.5V to 5.5V specification. Both components maintain ROHS3 compliance and share identical HTSUS classification. The AD7569BRZ is Active in product status with MSL 1 rating, providing superior moisture handling characteristics.

GS6042-INE3 and MAX7347AEE+ operate at reduced voltage levels (3.3V and 2.4V to 3.6V respectively) and are suitable only for applications where voltage domain conversion or separate power supplies are available. Both maintain Active status and ROHS3 compliance with MSL 1 ratings.

AD6623ASZ operates in a different functional domain (Transmit Signal Processor) with significantly different pin count (128 pins) and package footprint. Substitution requires complete circuit redesign and is not recommended for direct replacement scenarios.

AD9985ABSTZ-110 carries Last Time Buy status, indicating discontinued production. While ROHS3 compliant with matching MSL 3 rating, this part should not be selected for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can AD7569BRZ directly replace Z8523320ASG in existing designs?

A: AD7569BRZ shares compatible voltage specifications (4.75V to 5.25V overlaps with 4.5V to 5.5V) and maintains identical RoHS and HTSUS compliance. However, package differences (24-SOIC versus 44-LQFP) and pin count variation (24 versus 44 pins) require PCB layout modifications and functional verification of interface signal mapping.

Q: What is the significance of MSL rating differences between substitute parts?

A: MSL 1 (Unlimited) rated components such as AD7569BRZ, MAX7347AEE+, and GS6042-INE3 tolerate indefinite storage without moisture absorption concerns. MSL 3 (168 Hours) rated components including Z8523320ASG and AD9985ABSTZ-110 require controlled storage environments and have defined floor life limitations. Selection depends on supply chain handling and storage infrastructure.

Q: Why is AD9985ABSTZ-110 listed as a substitute if it is Last Time Buy?

A: AD9985ABSTZ-110 is documented as a historical substitute reference based on the provided part list. Last Time Buy status indicates production discontinuation. This part should not be selected for new designs or applications requiring long-term component availability.

Q: Are voltage domain differences between substitutes critical for selection?

A: Yes. GS6042-INE3 (3.3V) and MAX7347AEE+ (2.4V to 3.6V) operate in different voltage domains than Z8523320ASG (4.5V to 5.5V). Direct substitution requires additional power supply infrastructure or voltage regulation circuits. AD7569BRZ (4.75V to 5.25V) provides the closest voltage compatibility with minimal additional design considerations.

Q: What packaging considerations apply when selecting substitute parts?

A: Z8523320ASG uses 44-LQFP (10x10mm) package. Substitute parts employ different packages: GS6042-INE3 (16-QFN 4x4mm), AD6623ASZ (128-MQFP 14x20mm), MAX7347AEE+ (16-QSOP), AD7569BRZ (24-SOIC 7.50mm width), and AD9985ABSTZ-110 (80-LQFP 14x14mm). Package selection impacts PCB footprint, thermal characteristics, and assembly process compatibility. Direct pin-for-pin substitution is not possible with any listed alternative.
