Z8523310ASG Equivalent & Substitute Parts

Part Overview

The Z8523310ASG is a specialized interface integrated circuit manufactured by Zilog in a 44-LQFP package. This component is classified as Last Time Buy, indicating discontinued production with limited availability. The part operates within a 4.5V to 5.5V supply voltage range and is designed for surface mount applications. Finding equivalent and substitute parts is necessary due to the Last Time Buy status, which restricts future procurement and requires identification of compatible alternatives for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Z8523310ASG are identified based on the following criteria:

Primary Substitution Parameters:

• Category: Interface
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Voltage Supply Compatibility: Parts operating within or overlapping the 4.5V ~ 5.5V range
• REACH Status: REACH Unaffected

The substitute parts listed represent interface components from established manufacturers with Active or Last Time Buy product status. Substitution validity depends on functional equivalence within the interface category and compliance with the same environmental and regulatory standards. Package form factors vary among substitutes, requiring PCB layout evaluation during implementation.

Parameter Comparison

Engineering Selection Recommendations

LTC4306IGN#TRPBF (Analog Devices Inc.) is an Active product with extended voltage range compatibility (2.2V ~ 5.5V) and superior moisture sensitivity rating (MSL 1). This part is suitable for applications requiring long-term availability and reduced moisture handling constraints.

MAX7359ETG+ (Analog Devices Inc./Maxim Integrated) is an Active product with MSL 1 rating. Note that the supply voltage range (1.65V ~ 3.6V) does not overlap with the Z8523310ASG operating range, limiting direct substitution in 5V-only designs.

TDA8026ET/C3Y (NXP USA Inc.) is an Active product with voltage range compatibility (2.7V ~ 5.5V) and MSL 2 rating, providing moderate moisture sensitivity performance suitable for standard manufacturing environments.

TPL9201PWPR (Texas Instruments) is a Last Time Buy product with extended voltage range (0V ~ 5.25V) and MSL 2 rating. As a Last Time Buy component, this part shares availability constraints with the main part and may not provide long-term procurement advantages.

ZSC31050FAG1-R (Renesas Electronics Corporation) is an Active product with the widest voltage range (2.7V ~ 48V), MSL 1 rating, and automotive qualification (AEC-Q100). This part offers superior long-term availability and environmental robustness.

Frequently Asked Questions (FAQ)

Q: Can I directly replace Z8523310ASG with any of these substitute parts?

A: Direct replacement depends on functional equivalence and application requirements. All listed parts share the Interface category and ROHS3 compliance. However, package form factors differ significantly (44-LQFP vs. 24-SSOP, 24-TQFN, 64-TFBGA, 20-HTSSOP, 16-SSOP), requiring PCB redesign. Voltage supply ranges must be verified against your circuit design.

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

A: LTC4306IGN#TRPBF, MAX7359ETG+, TDA8026ET/C3Y, and ZSC31050FAG1-R all have Active product status, ensuring ongoing manufacturing and supply. TPL9201PWPR shares Last Time Buy status with the main part and should not be considered for long-term designs.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: MSL ratings indicate maximum exposure time to moisture before component degradation. The Z8523310ASG has MSL 3 (168 hours), while most substitutes offer MSL 1 or 2. Lower MSL values provide greater flexibility in manufacturing and storage without requiring specialized moisture control procedures.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 Compliant and REACH Unaffected, matching the environmental compliance profile of the Z8523310ASG.

Q: Does voltage supply range overlap guarantee compatibility?

A: Voltage range overlap is necessary but not sufficient for substitution. Functional behavior, interface protocols, and pin configurations must also be evaluated. The MAX7359ETG+ voltage range (1.65V ~ 3.6V) does not overlap with Z8523310ASG (4.5V ~ 5.5V), making it unsuitable for 5V-only applications.
