Z8523020VSC Equivalent & Substitute Parts

Part Overview

The Z8523020VSC is a specialized interface IC manufactured by Zilog in a 44-PLCC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates within a 4.5V to 5.5V supply voltage range and is designed for bus interface applications. Due to its obsolete status, identifying compatible alternatives is essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Z8523020VSC is determined by the following critical parameters:

Direct Substitutes (Same Package and Electrical Characteristics):

• Package compatibility: 44-PLCC / 44-LCC form factor
• Voltage supply range: 4.5V ~ 5.5V
• Interface type: Bus interface
• Mounting type: Surface mount
• Moisture sensitivity level: MSL 3

The Z8523020VSG qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while offering active product status and improved RoHS compliance.

Similar Substitutes (Different Package, Functional Equivalence):

• Functional category: Interface IC
• Voltage supply: 5V operation
• Interface capability: Specialized interface function
• Mounting type: Surface mount
• Active product status and RoHS compliance

The ADV7623BSTZ-P-RL represents a functional alternative with different packaging (144-LQFP) and enhanced specifications for HDMI interface applications, suitable when package constraints permit redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same PCB Layout): The Z8523020VSG is the primary substitute for the Z8523020VSC. Both parts maintain identical package geometry (44-PLCC), electrical specifications (4.5V ~ 5.5V), and interface characteristics (Bus). The Z8523020VSG offers the advantage of active product status and ROHS3 compliance, addressing regulatory requirements while maintaining full pin-for-pin compatibility.

For Functional Equivalence (Design Flexibility): The ADV7623BSTZ-P-RL provides functional interface capability with active product status and ROHS3 compliance. This substitute requires PCB redesign due to different package format (144-LQFP versus 44-PLCC) and is applicable only when layout modifications are feasible. The ADV7623BSTZ-P-RL is specifically designed for HDMI interface applications and operates at 5V.

Compliance Considerations: Both substitute parts meet REACH and EAR99 export classification requirements. The Z8523020VSG provides direct compliance improvement through ROHS3 certification while maintaining the original design. The ADV7623BSTZ-P-RL also provides ROHS3 compliance for new designs requiring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can Z8523020VSG be used as a direct replacement for Z8523020VSC without PCB modifications? A: Yes. The Z8523020VSG maintains identical 44-PLCC package geometry, pin configuration, voltage specifications (4.5V ~ 5.5V), and bus interface characteristics. No PCB layout changes are required.

Q: What is the primary difference between Z8523020VSC and Z8523020VSG? A: The Z8523020VSG is the active production variant with ROHS3 compliance, while the Z8523020VSC is obsolete and RoHS non-compliant. Both parts are electrically and mechanically identical.

Q: When should ADV7623BSTZ-P-RL be considered as a substitute? A: The ADV7623BSTZ-P-RL is suitable when PCB redesign is acceptable and HDMI interface functionality is required. This part uses a 144-LQFP package and requires layout modifications compared to the original 44-PLCC design.

Q: Are all substitute parts available in the same packaging format? A: No. The Z8523020VSG maintains the original 44-PLCC packaging. The ADV7623BSTZ-P-RL uses 144-LQFP packaging and requires different PCB footprint design.

Q: What is the moisture sensitivity level for these parts? A: All three parts (Z8523020VSC, Z8523020VSG, and ADV7623BSTZ-P-RL) have MSL 3 rating with 168-hour floor life requirements.

Q: Do substitute parts meet current regulatory requirements? A: The Z8523020VSG and ADV7623BSTZ-P-RL both meet ROHS3 compliance and REACH requirements. The original Z8523020VSC is RoHS non-compliant and should be replaced in new designs requiring regulatory compliance.
