Z0853008VSC Equivalent & Substitute Parts Reference

Part Overview

The Z0853008VSC is a specialized interface IC manufactured by Zilog in a 44-PLCC package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy product support, and procurement planning. The part operates within a 4.75V to 5.25V supply voltage range and is designed for serial interface applications. Due to its obsolete status, substitute components must be evaluated based on electrical compatibility, package compatibility, and functional equivalence within the interface category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Z0853008VSC are identified based on the following critical parameters:

• Category Match: All substitutes must belong to the Interface component category
• Mounting Type: Surface mount technology compatibility
• Interface Functionality: Serial or equivalent bus interface capability
• Supply Voltage Compatibility: Operating voltage ranges that support 5V logic systems
• Product Status: Active status preferred for long-term availability and support
• Compliance Standards: RoHS and REACH compliance status for regulatory alignment

The identified substitutes (MC33660BEFR2 and LM96570SQE/NOPB) meet the interface category requirement and surface mount criteria. However, each presents distinct trade-offs in voltage specifications, package form factors, and application focus that must be evaluated against specific system requirements.

Parameter Comparison

Engineering Selection Recommendations

MC33660BEFR2 Considerations: This NXP component is actively manufactured and ROHS3 compliant, providing regulatory alignment for new designs. The 8-SOIC package represents a significant form factor reduction compared to the 44-PLCC original. The supply voltage range of 8V to 18V exceeds the original 5V specification, requiring external voltage regulation if direct substitution is intended. The automotive-grade classification indicates enhanced reliability specifications. This part is suitable for applications where package miniaturization and long-term availability are prioritized over pin-for-pin compatibility.

LM96570SQE/NOPB Considerations: This National Semiconductor interface component is actively produced and ROHS3 compliant. The 32-WFQFN package offers moderate integration density between the original 44-PLCC and the 8-SOIC alternatives. The supply voltage range of 1.71V to 1.89V is incompatible with standard 5V logic systems and requires level-shifting or dedicated power supply design. This part is specified for ultrasound imaging transmit beamformer applications, indicating specialized functional design. This component is appropriate only for applications where the lower voltage specification aligns with system architecture.

Both substitutes offer active product status and improved compliance posture compared to the obsolete Z0853008VSC. Selection depends on system voltage requirements, PCB layout constraints, and functional application alignment.

Frequently Asked Questions (FAQ)

Q: Can MC33660BEFR2 directly replace Z0853008VSC in existing designs? A: Direct pin-for-pin replacement is not possible due to different package types (8-SOIC versus 44-PLCC) and pin counts. The higher supply voltage range (8V-18V versus 4.75V-5.25V) requires circuit redesign and voltage regulation considerations.

Q: Is LM96570SQE/NOPB suitable for general serial interface applications? A: No. The supply voltage range of 1.71V to 1.89V is outside standard 5V logic levels. This component is specified for ultrasound imaging applications and requires dedicated power supply architecture incompatible with typical 5V serial interface systems.

Q: What are the package compatibility implications? A: The Z0853008VSC uses a 44-pin PLCC package. MC33660BEFR2 uses an 8-pin SOIC package, and LM96570SQE/NOPB uses a 32-pin WFQFN package. Each requires distinct PCB layout and routing strategies. No substitute offers identical pin configuration.

Q: Are both substitutes RoHS compliant? A: Yes. Both MC33660BEFR2 and LM96570SQE/NOPB are ROHS3 compliant, whereas the original Z0853008VSC is RoHS non-compliant. This compliance improvement supports regulatory requirements for new product designs.

Q: What is the moisture sensitivity consideration? A: The Z0853008VSC and MC33660BEFR2 both specify MSL 3 (168 Hours), indicating identical moisture handling requirements. LM96570SQE/NOPB does not specify MSL, requiring clarification from the manufacturer for moisture-sensitive applications.

Q: How should voltage supply differences be addressed? A: MC33660BEFR2 requires 8V-18V supply, necessitating external voltage regulation if the system provides 5V. LM96570SQE/NOPB requires 1.71V-1.89V supply, incompatible with standard 5V systems without level-shifting circuitry. System architecture must be evaluated before substitution.
