MPC507APG4 Equivalent & Substitute Parts

Part Overview

The MPC507APG4 is a dual 8:1 multiplexer/demultiplexer IC manufactured by Texas Instruments, housed in a 28-DIP package with 1.5kOhm on-state resistance. This component functions as an analog switch matrix for signal routing applications requiring dual-channel multiplexing capability.

The MPC507APG4 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this interface component.

Substitute Part Grouping Explanation

Substitution eligibility for the MPC507APG4 is determined by the following critical parameters:

Multiplexer Configuration: Must be 8:1 dual-circuit topology
Package Type: Must be 28-DIP form factor for mechanical and electrical compatibility
Voltage Supply Range: Must accommodate the ±5V ~ 22V dual supply specification
On-State Resistance: Substitute parts with lower on-state resistance values are electrically compatible and provide improved performance characteristics
Switch Timing: Substitute parts with faster or equivalent switch times maintain signal integrity
Operating Temperature: Substitute parts must support the required temperature range or a subset thereof
RoHS Compliance: Must maintain ROHS3 compliance for regulatory alignment

The DG507ACJ+ from Analog Devices Inc./Maxim Integrated meets these substitution criteria while offering enhanced electrical performance through reduced on-state resistance (450Ohm vs. 1.5kOhm) and improved leakage characteristics.

Engineering Selection Recommendations

The DG507ACJ+ is an active, in-production substitute for the obsolete MPC507APG4. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The DG507ACJ+ provides superior electrical performance through lower on-state resistance (450Ohm vs. 1.5kOhm), resulting in reduced signal attenuation and improved channel isolation. The substitute part exhibits lower leakage current (5nA vs. 500pA), beneficial for low-power or high-impedance signal applications.

Design considerations for substitution include the DG507ACJ+ operating temperature range (0°C ~ 70°C) versus the MPC507APG4 range (-40°C ~ 85°C). Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must evaluate thermal requirements against the substitute part's specifications. The DG507ACJ+ dual supply voltage range (±4.5V ~ 18V) is narrower than the MPC507APG4 (±5V ~ 22V); designs operating at supply voltages exceeding ±18V require verification of compatibility.

Both components share identical 28-DIP package geometry and pinout, enabling direct mechanical substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the DG507ACJ+ directly replace the MPC507APG4 without PCB modifications?

A: Yes. Both components utilize the 28-DIP package with identical form factor (0.600", 15.24mm) and pinout configuration, enabling direct mechanical and electrical substitution without PCB layout changes.

Q: What are the key electrical differences between these parts?

A: The DG507ACJ+ features lower on-state resistance (450Ohm vs. 1.5kOhm), lower leakage current (5nA vs. 500pA), and higher channel capacitance (6pF/45pF vs. 5pF/25pF). The MPC507APG4 offers faster turn-on time (200ns vs. 1µs) and wider supply voltage range (±5V ~ 22V vs. ±4.5V ~ 18V).

Q: Are there temperature range limitations with the DG507ACJ+?

A: The DG507ACJ+ operates from 0°C to 70°C, compared to the MPC507APG4 range of -40°C to 85°C. Applications requiring operation below 0°C or above 70°C must confirm compatibility with the substitute part's thermal specifications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the MPC507APG4 and DG507ACJ+ are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for equivalent component selection.

Q: What is the supply voltage compatibility range for the DG507ACJ+?

A: The DG507ACJ+ operates with dual supply voltages from ±4.5V to ±18V. Designs requiring operation at supply voltages exceeding ±18V must verify compatibility with this specification.
