MPC506AP Equivalent & Substitute Parts

Part Overview

The MPC506AP is a 16:1 analog multiplexer/demultiplexer IC manufactured by Texas Instruments, housed in a 28-DIP package. This component functions as a single-circuit switch with 1.5kOhm on-state resistance, designed for signal routing and selection applications. The MPC506AP is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPC506AP is determined by the following criteria:

Primary Compatibility Requirements:

• Multiplexer/Demultiplexer configuration: 16:1
• Number of circuits: 1
• Package type: 28-DIP (0.600", 15.24mm)
• Mounting type: Through Hole

Electrical Operating Range:

• Dual supply voltage compatibility within the specified range
• Operating temperature range coverage

Performance Parameters:

• On-state resistance (lower values indicate improved performance)
• Switch timing characteristics
• Leakage current specifications
• Channel capacitance values

The three substitute parts listed—ADG506AKNZ, DG506ACJ+, and HI3-0506A-5Z—meet the primary compatibility requirements. All three maintain the 16:1 multiplexer configuration, single-circuit topology, and 28-DIP package format. Electrical performance varies across substitutes, with differences in on-state resistance, supply voltage ranges, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

ADG506AKNZ (Analog Devices Inc.) is classified as active product status, ensuring ongoing manufacturer support and availability. This part offers the lowest on-state resistance at 300Ohm, providing superior signal integrity compared to the MPC506AP. The ADG506AKNZ operates within a narrower dual supply voltage range (±10.8V ~ 16.5V) and maintains the full operating temperature range of -40°C ~ 85°C. Switch timing is slightly slower at 300ns for both Ton and Toff. This substitute is suitable for applications where lower on-state resistance and active product support are priorities.

DG506ACJ+ (Analog Devices Inc./Maxim Integrated) maintains active product status with on-state resistance of 450Ohm. This part supports the widest dual supply voltage range (±4.5V ~ 18V), accommodating the MPC506AP's specified range. However, the operating temperature range is limited to 0°C ~ 70°C, which does not cover the full -40°C ~ 85°C specification of the original part. Switch timing shows Ton of 1µs, which is significantly slower than the MPC506AP. This substitute is applicable only in applications operating within the 0°C ~ 70°C temperature window.

HI3-0506A-5Z (Renesas Electronics Corporation) is classified as obsolete, matching the product status of the MPC506AP. On-state resistance is 1.8kOhm, closely approximating the original 1.5kOhm specification. This part operates at a fixed dual supply voltage of ±15V, which falls within the MPC506AP's range. Operating temperature range is 0°C ~ 75°C, providing partial coverage of the original specification. This substitute is suitable for legacy system maintenance where obsolete component replacement is required.

Frequently Asked Questions (FAQ)

Q: Can ADG506AKNZ be used as a direct replacement for MPC506AP in all applications?

A: ADG506AKNZ is mechanically and functionally compatible as a 16:1 multiplexer in the 28-DIP package. However, the dual supply voltage range is narrower (±10.8V ~ 16.5V versus ±5V ~ 22V). Applications requiring operation below ±10.8V or above ±16.5V cannot use this substitute without circuit modification.

Q: What are the temperature limitations when substituting with DG506ACJ+?

A: DG506ACJ+ operates from 0°C ~ 70°C, which is narrower than the MPC506AP specification of -40°C ~ 85°C. This substitute is unsuitable for applications requiring operation below 0°C or above 70°C.

Q: How does on-state resistance affect circuit performance?

A: On-state resistance determines signal attenuation and impedance characteristics. ADG506AKNZ (300Ohm) provides lower impedance than MPC506AP (1.5kOhm), improving signal fidelity in high-impedance applications. HI3-0506A-5Z (1.8kOhm) closely matches the original specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ADG506AKNZ, DG506ACJ+, and HI3-0506A-5Z are all ROHS3 compliant, matching the environmental compliance of the MPC506AP.

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

A: ADG506AKNZ and DG506ACJ+ are classified as active products, ensuring ongoing manufacturer support and supply chain availability. HI3-0506A-5Z is obsolete, similar to the MPC506AP.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, all substitute parts use the same 28-DIP (0.600", 15.24mm) package and through-hole mounting configuration, allowing direct PCB footprint compatibility without layout modifications.
