Z80C3010VSC Equivalent & Substitute Parts

Part Overview

The Z80C3010VSC is a specialized interface integrated circuit manufactured by Zilog, housed in a 44-PLCC package. This component operates within the 4.5V to 5.5V supply voltage range and is classified as an obsolete product. Due to its obsolete status, identifying functionally equivalent substitute components is essential for system redesign, legacy system maintenance, and ensuring continued availability for production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the Z80C3010VSC are identified based on the following critical parameters:

• Category: Interface
• Interface Type: Bus connectivity capability
• Voltage Supply Range: 4.5V ~ 5.5V compatibility
• Mounting Type: Surface Mount
• Package Compatibility: 44-PLCC or equivalent pin count/footprint alternatives
• Product Status: Active or current production status preferred for long-term availability

The substitute parts listed below meet varying degrees of these criteria. The Z80C3010VSG maintains the closest functional equivalence through identical voltage specifications and package type. Alternative substitutes (MC33660BEF, MXL1344ACAG+T, NCT6102D) provide interface functionality within different package configurations and voltage ranges, requiring design evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Z80C3010VSG is the primary substitute candidate. It shares identical voltage specifications (4.5V ~ 5.5V), package configuration (44-PLCC), and interface type (Bus) with the Z80C3010VSC. The Z80C3010VSG maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements for new designs while preserving functional compatibility.

MC33660BEF provides interface functionality with active product status and ROHS3 compliance. However, it operates within an 8V ~ 18V supply voltage range, incompatible with the original 4.5V ~ 5.5V specification. The 8-SOIC package differs significantly from the 44-PLCC footprint, requiring PCB redesign. This substitute is suitable only for applications where voltage and package modifications are feasible.

MXL1344ACAG+T is a cable terminator interface component with active product status and superior moisture sensitivity characteristics (MSL 1). It maintains 4.5V ~ 5.5V voltage compatibility but operates in a 24-SSOP package with only 6 terminations. This component is applicable only for cable termination-specific applications and requires functional verification.

NCT6102D is a controller interface component with active product status and ROHS3 compliance. It operates at a fixed 5V supply voltage and uses a 128-LQFP package. The significantly larger pin count and different interface classification (Controller versus Bus) indicate this component is suitable only for applications requiring controller-level interface functionality with substantial redesign effort.

Frequently Asked Questions (FAQ)

Q: Can Z80C3010VSG be used as a direct replacement for Z80C3010VSC?

A: Z80C3010VSG is the closest functional equivalent. Both components share identical voltage specifications (4.5V ~ 5.5V), package type (44-PLCC), and bus interface classification. The primary difference is product status: Z80C3010VSC is obsolete while Z80C3010VSG is active. Pin-for-pin compatibility should be verified against detailed datasheets before implementation.

Q: Why does MC33660BEF have a different voltage range?

A: MC33660BEF is manufactured by NXP USA Inc. and is designed for automotive-grade applications requiring 8V ~ 18V operation. This voltage specification reflects its intended application domain and is not compatible with the original 4.5V ~ 5.5V requirement without additional voltage regulation circuitry.

Q: What does MSL 1 (Unlimited) on MXL1344ACAG+T mean compared to MSL 3 (168 Hours)?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (Unlimited) means the component has no time restriction and can be stored indefinitely under standard conditions. MSL 3 (168 Hours) limits storage to 168 hours after moisture exposure. MXL1344ACAG+T offers superior moisture tolerance for extended storage scenarios.

Q: Is package compatibility the only consideration for substitution?

A: No. Voltage supply range, interface type, pin count, and functional classification must all align with application requirements. While Z80C3010VSG matches the original package, MC33660BEF, MXL1344ACAG+T, and NCT6102D require package redesign and functional verification due to different electrical specifications and interface types.

Q: Are all substitute parts RoHS compliant?

A: Z80C3010VSC is RoHS non-compliant. All listed substitutes (Z80C3010VSG, MC33660BEF, MXL1344ACAG+T, NCT6102D) are ROHS3 compliant, meeting current environmental regulations for new designs and production.

Q: What is the base product number and how does it relate to substitution?

A: The base product number identifies the core component family. Z80C3010VSC and Z80C3010VSG share the base product number Z80C30, indicating they are variants within the same product line. This relationship supports their functional equivalence for substitution purposes.
